Clash of the Financial Titans 10-18

Clash of the Financial Titans

Financial market observers may have suffered a bit of cognitive whiplash with this week’s announcement of the joint winners of the Nobel Prize in economics. Two of the winners appear, on first glance, to be polar opposites. Eugene Fama is the father of the iconic efficient markets theory, and Robert Shiller suggests that markets are anything but efficient – often greatly overreacting or underreacting to new information. But Wharton finance professor Amir Yaron says that the ideas of the two winners are ultimately complementary. In this Knowledge@Wharton podcast, he explains why.
An edited transcript of the conversation follows.
Knowledge@Wharton: We’re meeting today with Amir Yaron, a Wharton finance professor, about the recent awarding of the Nobel Prize in economics to Eugene Fama and Lars Peter Hansen of the University of Chicago, and Robert Shiller, from Yale. All won for their work covering trends in asset prices. So, thank you for joining us at Knowledge@Wharton today, Amir.
Amir Yaron: Thank you.
Knowledge@Wharton: There are a couple of interesting things about this year’s winners. Professor Fama is famous for his ideas that markets are efficient. This has long been textbook theory, since he introduced these ideas in the late 1960s, early 1970s — that they reflect all the information – at least, publicly available information — that’s out there.
One idea that flows from this is that you can’t really predict what markets will do in the future, because prices have already taken into consideration all the possibilities. Robert Shiller, you might say, comes along and says [in effect], wait, not so fast. Markets are not that rational. In fact, they can be irrational. They can be too exuberant, too depressed. They overreact, and underreact, in an emotional way.
So, at first glance, it seems a bit odd for these two finance minds to share the Nobel Prize, because in some ways, they seem to be polar opposites. Could you give your views about that?
Yaron:  Sure. There’s an element of correctness in that polar view idea that you are stating. But I think there’s a broader message about trying to analyze financial markets. And the way I view the connection is that Gene’s early work focused mostly on short-run predictability. By and large, they’ve shown, using daily or specific announcements, or even weekly or monthly [ones], that there’s very little room for predictability. And I think that evidence, by and large, stands. In fact, that led to practical issues such as [the creation of] index funds — things that have really helped the common person, in the sense of the construction of a low-fee index funds. So, there’s clear contribution there.
The work of Shiller showed – what he’s really cited for is less for the elements of underreaction or overreaction that are due to psychology — his excess volatility paper, which  just shows that prices have moved too much, relative to purely constant discount dividends. And then, later on [he] also showed that there is [price] predictability over a multi-year horizon.
One has to understand that this is an important finding. But that finding can be interpreted by a rational model that either attributes [cause and effect in price changes longer term] to different risk aversions, or to different market conditions, which would justify, let’s say, low prices in a recession, that can therefore predict future expected return, and rationalize it. Or, it could be interpreted as [as result of] some behavioral elements that may change expectation. And part of what we are still doing research on is trying to decipher those two phenomena. But the two [views] are complementary, in my view, rather than polar opposites — at least in terms of the findings that the Nobel committee has posed.
Knowledge@Wharton: As a common denominator, would it be fair to say that both [Fama and Shiller] are saying that prices are difficult to predict in the short term, but in the medium and longer term, there’s some ability to make some reasonably accurate predictions?Yaron:  There are certainly certain variables. Let’s say if we’re talking about the aggregate market portfolio, such as the price-dividend ratio. We know that when that’s low, it tends to predict higher return down the road. And the question is, is that due to some behavioral traits? Or, as I mentioned, it could be interpreted that we are in a recession. People are highly risk-averse. We are seeing low cash flows, and therefore people demand higher expected return down the road. And that’s the form of predictability. One could be interpreted [as a result of] … a rational world. And another [interpretation] could be as a more behavioral finance interpretation, which is sort of the path that professor Shiller had taken subsequently.
Knowledge@Wharton: The idea of polar opposites could be seen in that some people have argued that Fama’s ideas and theories didn’t see the financial crisis that began in 2008 coming, whereas Shiller’s view of the world kind of predicted it. And therefore, in that sense, they did have different ways of looking at the world.
Yaron: Well, obviously, Shiller is partly known in the popular press for calling the dot-com and the housing market [bubbles]. As to Gene, I think he would just say – you know, markets, the volatility in the market, it was expected upon such a crisis. That’s what you expect in an efficient market, where it’s hard to aggregate, and there’s a lot of uncertainty, and the difficulty of calling it is inherent in what is happening in such markets.
Knowledge@Wharton: The third prize-winner, who hasn’t gotten quite as much attention as the other two famous names, is Lars Peter Hansen, who you actually have a personal relationship with. Could you talk about that briefly, and then tell us about his ideas?
Yaron: Lars was my main advisor at Chicago. I know him very well. I’ve actually written a paper with him. Lars’ contribution is in developing statistical models, for testing many of the theories that we’ve discussed. The very theory basically asserts that if you save a dollar today, you have an expected return on what that dollar will give you tomorrow. He laid out the foundational ground for doing the testing, and that’s called the general method of moments.
And in the original test, what a dollar means to you today in utility and in the future, the specifications were very simple, and the basic model was rejected. And that was consistent with the notion of rejecting the consumption CAPM [the capital asset pricing model], which is consistent with the Shiller finding that prices were too volatile to be reconciled by a simple [calculation of the] present value of dividends.
Knowledge@Wharton: When you say the model was rejected, what do you mean, exactly?
Yaron:  What it means is when you compare in the data, the cost side of saving a dollar today, versus the benefits of getting tomorrow the dollar and the expected return, those didn’t seem to be lined up with reasonable risk attitudes that we think ought to [be able to] reconcile them with. And so, the profession has moved on, consistent with these two background topics that you’ve mentioned: the lack of predictability in the short run, and some predictability in the longer term by Shiller. And this evidence has moved on, in a couple facets. One is to change the preferences, but still stay in a rational world. So, when I say change preferences, I mean … for example, [recognizing] that people are very risk-averse in a recession. And when they see a lot of uncertainty or low expected cash flows, price-to-dividend ratios are low. But nonetheless, expected returns are high. And that is a completely rational story.
Another approach is to go somewhat to the behavioral route, and basically claim that people have certain behavioral biases, and that changes their expectations. And that could [lead to] some changes. A third approach would be to essentially talk more about market frictions. 
That cost and benefit side that I mentioned – saving today, borrowing today to invest in the market, is not so easily done…. And in this mix, there’s also the issue of how you measure the risks — the present value of dividends. Obviously [that carries] uncertainty. We see the Vix [the Chicago Board Options Exchange Market Volatility Index, often called the fear index] now, and other measures of uncertainty. They become very important. And so, just the measured risks have been challenged, to some extent. And I’ll put in a plug for my own work, which is actually related to that. I like to think it actually influenced some of Lars’ more recent work, which has to do with whether we are measuring the riskiness in dividends and in uncertainty appropriately.
So, if you look at U.S. dividends, they look very much like what we call white noise, which would not rationalize a lot of risk.
Knowledge@Wharton: Why do they look like white noise?
Yaron:  They go up and down. So, if you just look at them in a plain vanilla sense, you would think they shouldn’t be too risky. But if you looked at them more carefully, there is some signal there. And part of the debate is whether that signal is there or not — and those are statistical issues. But if it’s there, and with appropriate preferences, again, with a rational story, you can go a pretty long way towards reconciling some of the price movement that we’ve observed. And so, Lars’ contribution has been in developing these methods, pushing them, and also developing methods about what we call alternative preferences, where people are afraid of not knowing the environment they are living in.
So, in that sense, he’s also filling up the gap, to some extent, you could say, a little bit between Shiller and Fama, in the sense that he’s not strictly viewed as a behavioral. But some of his very recent research on robust control, and with another Nobel Laureate –Tom Sergeant — has pushed the agenda of robust control, which takes very seriously the idea that agents are not completely confident of what environment they are in. And consequently, they are behaving [as if they were] in a more fearful environment. And that affects prices in a particular way.
Knowledge@Wharton:  So, when an individual investor is going to make a decision about what they’re going to invest in, how do those ideas fit into what might be an unconscious decision for them?
Yaron:  One way that we examine the data is on the aggregate economy. And we often look at aggregate data. And that view is in the context of the consumption [based] CAPM [or CCAPM] — that somebody there on the margin is saving a dollar today, let’s say, and investing it. And they’ve got to be compensated the right way. And they are very cognizant when they do that. Of course, there are a lot of people who are – partly because of the lack of predictability — sort of happy, and should be happy, putting their money in index funds, because it’s going to be quite difficult to beat the market by timing it.
Knowledge@Wharton:  And this is what professor Fama’s theory had led to, which is you can’t really predict the market. Therefore, an index fund … just tracks the general market.
Yaron:  The general markets. Right. And it saves you costs. And so, that’s in terms of the aggregate. Gene also later developed issues about, actually, the failure of the CAPM, in the cross-section. The CAPM basically tells you that stocks that have high-exposure to the market return should have the highest return. But he also showed that other factors – their exposure to size, and their exposure to book-to-market – is very important for understanding the universe of returns. And that has also translated into very practical notions. If you go to many investment houses today, you will see that the universe of stock advice is: Do you want to invest in high growth? Do you want to invest in value? Big [large cap], small? That is, in some sense, a testament of how that research got translated very fast into practical implementation in the real world.
Knowledge@Wharton: Could you just make that connection? How that led to this segregation of the theories?
Yaron:  Well, it suggests that it’s not just the market that is the sort of univariate risk that’s out there.…  But rather, there are these other two risk factors: Book-to-market, which you can think of as value stocks versus growth stocks, [and size]. …When you go and first put your money [down], [analysts will] divide up the universe of stocks in that dimension. And I think that’s a testament [to the theories], that that view has transcended to the practitioners’ side. Today, when people propose a new model, and whether a particular model is supposed to generate a trading strategy or a better return, it is often benchmarked against what’s called the Fama-French three-factor models. So, it needs to show that it gets a better return not against the CAPM but against this three-factor model.
Knowledge@Wharton: So many modern investment ideas have their foundation on Fama’s ideas. Why do you think it took so long for him to get the recognition that he got this week?
Yaron: I don’t have a great answer to that. His name was out there for a while. Maybe they thought, this is the balance [awarding Fama the Nobel Prize jointly with Shiller]. This balanced view is the right view. I’m not sure. This is probably something the committee should answer.

Social Activist Anna Hazare: ‘The First Task Is to Remove Corruption’ 10-18

Social Activist Anna Hazare: ‘The First Task Is to Remove Corruption’

In 2011, Indian social activist Anna Hazare hit the headlines when he went on a fast demanding a comprehensive and effective Citizen’s Ombudsman Bill, popularly known as the Jan Lokpal Bill. The 74-year-old Gandhian, who began his journey in 1975 promoting rural development, is now seen as a crusader against corruption. Hazare believes that the Jan Lokpal Bill will ensure that the money meant for development would reach the common man and not get diverted.
In a conversation with Knowledge@Wharton and Devesh Kapur, director of the University of Pennsylvania’s Center for the Advanced Study of India  , Hazare talks about the inspiration behind his social activism, his philosophy and his vision for India. “If we manage to create social pressure, then we can agitate on any issue in the country,” he says.
An edited transcript of the conversation follows. (Video in Hindi available below.)
Knowedge@Wharton: What inspired you to become a crusader against corruption?
Anna Hazare: Very early in life, I was inspired by [Swami] Vivekananda [a 19th century Indian monk]. I used to wonder about the meaning of human life all the time. Everyone begins life empty handed and­­­ ends it empty handed. But throughout life, people keep running, hankering after things, desperately trying to have everything. That puzzled me. What is the meaning of this race? What is the purpose of all this? Why did God create this world at all? ….
One day, at the New Delhi railway station, I chanced upon a book by Vivekananda. It was a revelation. It shed light on my dilemma. It told me about the purpose of my life. Human life has been created for service. To serve others should be the aim of life. We call four walls a mandir(temple), a mosque or a gurudwara. So also, our nation is a temple. To serve this nation, to serve the people, is to serve God. This is what I understood after reading Vivekananda. And then, at the age of 26, I made a decision. I decided that my life [would] be dedicated to the service of the people [and] the nation.
In the beginning, [inspired by Mahatma Gandhi] I took up the work of development of villages. I created a model village. And then I discovered that this development work suffers from leaks caused by corruption. Unless these leaks are plugged, no development is possible. That is how I took up the issue of corruption and started a movement against it. Remember, my work on rural development started in 1975 and in 1990 I started the movement against corruption. Wherever I found instances of corruption, I agitated against them.
Knowledge@Wharton: You have been in public life since you were 26. What was the biggest challenge you encountered and how did you deal with it?
Hazare: When we start working at the grassroots, there is usually someone whose fortunes are bound to suffer due to our work. He feels threatened. He will oppose you. There [are] black-marketers, there are Patels or village chieftains, who control everything in the villages. They feel that if this movement succeeds and things start working according to rules they would become insignificant. There are opponents of this type we have to face. But since I had decided to dedicate my life to the service of the people, I was very sure about the correctness of my path. Nothing could deter me. I did not stop.
I have five principles that rule my life: Shuddh achar[clean conduct]; shuddh vichar [clean thoughts];nishkalank jeevan [life without blemishes]; jeevan mein tyag [a life of sacrifice]; and strength to face insults without flinching. These five principles have helped me remain steadfast in the face of all adversities.
Knowledge@Wharton: What were your hopes or dreams when you started your movement? And how have your ideas and strategies changed as a result of your experience?

Hazare: As I told you, I decided very early in life that I have to serve the people. And that is why I decided that marriage and family was not for me. If I was a married man, my life would have been consumed earning bread and butter to sustain my [family]. I kept working without aspiring for any returns. Karmanye vadhikaraste, Ma phaleshu kada chana [Your duty is to act but be detached from the fruits of your actions.] With this in mind, I went on working. How does one get frustrated? Only when one has some expectations.
As I gained new experiences in my movement, I made changes, adopted new strategies. Initially, I was working at the level of the state (province). Then I felt that corruption [has] pervaded our entire nation. And the idea of Jan Lokpal (Citizen’s Ombudsman) emerged.

 We thought that we should put pressure on the government to enact a law for Jan Lokpal. This is how we brought a change in our movement. In the beginning, we got the Right to Information Act. Then the issue of Gram Sabha (local self- government) drew my attention.

 After that I saw that people have to run from one table to another to get their work done. So, I thought about a law to ensure that public services are delivered in time. Since I did not have any selfish interest to serve, all this could be done …. I got ideas from my lived experiences.
Devesh Kapur: In your opinion, what is the root cause of corruption?
Hazare: The root cause of corruption is selfishness; the selfish nature of human beings. They go to any lengths to pursue their self-interest …. Second, there is no deep thinking about the purpose of life. And since there is no purpose to life, we want to fill that void with commodities, things. You become an MLA (member of legislative assembly) and an MP (member of Parliament) and in a short period of two or three years, you become a billionaire. How? Do you really need so much? Since you keep increasing your needs, corruption increases.
Kapur: If self-interest is the root of corruption, then how do you think the new Jan Lokpal legislation is going to make a difference? Do we expect the Lokpal to control selfishness?
Hazare: Today, the common masses find it impossible to make both ends meet. Poor people cannot get their work done without dishing out money as bribes. How can they live then? Corruption leads to inflation in the prices of things. Due to corruption only 10% of the money raised for development reaches its target. I have given my life to serve the people. 

Their misery led me to think that Jan Lokpal could be a way of ensuring a just life for the masses. If the law for Jan Lokpal were enacted, the money meant for development would at least be used for it and would not be plundered. We would be able to develop our country. The poor would get justice. This thinking led me to fight for Jan Lokpal.
Kapur: Forty years ago, [political leader] Jayaprakash Narayan (JP) had launched a mass movement. But that achieved little as regards corruption. In your view, what was his mistake?
Hazare: The JP Movement in itself was excellent, very powerful. For the first time in independent India we saw a real mass movement. The flip side was his decision to include political parties. He had no idea that these parties would use this movement to achieve their own partisan ends.
Knowledge@Wharton: JP had called for ‘Total Revolution.’ What should be the slogan for the youth of our times?
Hazare: I say that we need total transformation of the system. Total transformation of the system would require a lot more than the Jan Lokpal. If you want to eradicate corruption, you would need the Right to Reject [elected representatives] and the Right to Recall. Only a combination of these measures can put a brake on corruption. And after this we‘ll need to turn to the farmers.
 In India, farming is still the main occupation of the masses. What is the condition of the farmers? While talking about total systemic transformation, we have to keep the farmer in mind. He should get a real return for his investment in farming, he should be able to realize the real value of his work. Then there are the working masses. [The ruling elite] are sucking the blood of these laborers.
Nature and humanity are being plundered. This is not true development. So, the problems of farmers and labor have to be kept in mind when we speak about transforming the system. Then comes education, which is a very important area. We find that educational shops are mushrooming. It has been commercialized in a crass manner. We have to change that through a total transformation of the system.
Knowledge@Wharton: How would you bring about this total transformation? 

What is your strategy?
Hazare: First, we have to ensure that laws like Jan Lokpalare adopted. These laws would guarantee that the money which gets squandered or diverted due to corruption reaches its target. If it gets fully used for development, we’ll see its fruits. So, the first task is to remove corruption. Then comes the right to reject and recall. We have to see to it that the right kinds of people are sent to legislative bodies, the Parliament ….
Knowledge@Wharton: Thirty or forty years ago, people believed that the license-permit regime in India was the source of corruption. But 1991 saw the advent of liberalization. Liberal reforms meant deregulating the economy. How did things change after liberalization? Did corruption increase or decrease after liberalization?
Hazare: What we have seen is a phenomenal growth in corruption. It has not decreased at all. There could be many reasons for that. But the main reason, according to me, is increasing criminalization of politics. Political parties give tickets to criminal elements, rapists, corrupt people, and ensure that they are elected as people’s representatives. When such people reach Parliament what occupies their minds is not development. They are busy cornering money for themselves. And this leads to an increase in corruption.
Kapur: You are right about political parties giving tickets to criminals. But why do people elect them?
Hazare: I agree with you. People are at fault here. But this is because people do not know what our Constitution says. Nowhere in the Constitution do we find the political party system mentioned. What does it say? People should have independent candidates in place of candidates of political parties, and to elect persons with impeccable credentials. Deviation from this started in the first Parliamentary elections in 1952. In that general election political parties contested against one another. Contrary to constitutional provisions, they got elected and sat in power and destroyed our Constitution. Our democracy was destroyed by these political parties ….

We keep beating the drum of democracy. Where is it, I ask? Democracy as we know it, for the people, by the people, of the people, where is it? What we have today is ‘party’cracy, ‘government’cracy. There is no democracy …. Today you see corruption everywhere. The party system is to blame for this. Money fetches power, power brings money. Read our Constitution, you will not find the party system there.
Kapur: You and (social activist) Arvind Kejriwal were together in the anti-corruption movement. Later, Kejriwal decided to start his political party. You did not agree with him. Why?
Hazare: I believe in my Constitution. India has to abide by it. Laws are made in accordance with the constitutional values and provisions. I still have faith in it. And therefore I cannot agree with the party system. I am busy in my awareness drive, trying to awaken people. If the voter is convinced that the political party system has to be done away with for real democracy, he can do it.
Knowledge@Wharton: What are your most significant achievements? What would you like to achieve in the future?
Hazare: The most significant achievement in my view is rural development. Mahatma Gandhi had said that we will have to transform our villages if we wanted to transform our nation. And we did it in practice …. First, we adopted some villages. Around 80% people living there were going hungry. They had nothing to eat, not a drop to drink. It was a drought-prone area.
We promoted rain harvesting and encouraged people to recharge the ground water. In a village where it was impossible to irrigate 350 acres of land to get a single crop, now we have enough water to ensure two crops for an area of 1,500 acres of land. The village economy there has been totally transformed. A village that could barely produce 400 liters of milk is now selling 5,500 liters. This was Mahatma Gandhi’s dream. We have to change our villages to change the country.
Secondly, if we want to change the nature of the economy of our country, we’ll have to change the economy of our villages. Unless we do it, the national economy would remain where it is now. What is important is to understand that a development based on the destruction of nature cannot sustain itself. It is not viable. We have adopted 50 villages, a very small number if you look at the size of our nation.
Knowledge@Wharton: What do you want to do next?
Hazare: First, to speed up rural development. Second, to get the laws on Jan Lokpal, Right to Reject, Right to Recall, enacted. I want to organize at least five crore (50 million) people, if not 120 crore. I am traveling extensively, trying to persuade people to join this movement. If we manage to create this social pressure, then we can agitate on any issue in the country. But that is in the future.

Incentive plan for Washington teachers drives performance gains, Stanford, Virginia researchers say 10-18

Incentive plan for Washington teachers drives performance gains, Stanford, Virginia researchers say


New study counters earlier research showing performance pay is ineffective, and suggests that under certain conditions incentives influence behavior.


SmileyManWithAHat/Creative CommonsD.C. school bus with Capitol in the background.
Researchers examined the teacher incentive plan at Washington, D.C., schools.
IMPACT, the controversial teacher-evaluation system recently introduced in the District of Columbia Public Schools (DCPS), appears to have caused hundreds of teachers in the district to improve their performance markedly while also encouraging some low-performing teachers to voluntarily leave the district's classrooms, according to a new study from the Stanford Graduate School of Education   and the University of Virginia Curry School of Education  .
IMPACT is a performance-assessment system linking high-powered incentives and teacher evaluations. It grabbed immediate national attention for its explicit dismissal policy for teachers it rated as ineffective as well as for its substantial financial rewards for high-performing teachers.
Specifically, high-performing teachers as assessed by IMPACT earn an annual bonus of as much as $25,000, as well as an opportunity for similarly large and permanent increases in their base salaries. In contrast, teachers who are unable to achieve an "effective" rating after two years are dismissed.
The findings run counter to a spate of recent studies that found that incentives linked narrowly to test scores were not associated with a change in teacher performance. The study   will be posted this week as a National Bureau of Economic Research (NBER) Working Paper.
"IMPACT provides a unique opportunity to examine the effects of a multi-faceted system of teacher evaluation and supports coupled with non-trivial incentives for teacher performance. We find strong evidence that this system causes meaningful increases in teacher performance," said James Wyckoff  , a professor of education at the University of Virginia Curry School of Education and co-author of the study.

Teacher assessments

"We know that good teachers make a dramatic difference in the lives of their students. However, we also know that there is considerable variation in teacher quality and too many disadvantaged children don't have access to the highly effective teachers they need to realize their potential," added Thomas Dee  , a professor of education at the Stanford Graduate School of Education and co-author of the study.
To try to address that issue, DCPS introduced IMPACT during the tenure of Chancellor Michelle Rhee and first began evaluating teachers during the 2009-10 school year. IMPACT's teacher performance assessments are based on multiple measures of performance, not just students' test results. Teachers, for example, are observed in their classrooms five times throughout the year and rated on nine explicit criteria that the district uses to define effective instruction, including how well they explain concepts and if they check for student understanding. School administrators also rate DCPS teachers on their support of school initiatives, their efforts to promote high expectations and their demonstration of core professionalism.
The aggregation of these measures rates teachers on a scale of 100 to 400. A score of 350 or more means highly effective; 250 or more, effective; under 250, minimally effective; and under 175, ineffective.
Teachers who score above 350 receive a bonus for a given year, and a permanent pay increase if they exceed the bar a second consecutive year. Effective teachers receive their scheduled pay increases while ineffective teachers are immediately dismissed. The "minimally effective" teachers (i.e., scores below 250 but above 174) are told they have one year to become effective or they face the threat of dismissal.
Since the study was completed, the district has made adjustments to the scoring scale.

The results

The study found that in IMPACT's first year a minimally effective rating had no clear effect on either a teacher's retention or their performance. However, following the second year of IMPACT, the authors found that teachers who had one minimally effective rating were much more likely to voluntarily exit and those who remained disproportionately improved. Similarly, teachers eligible for increases in base pay as a result of being rated highly effective twice also showed strong improvement relative to high performing teachers not eligible for the pay increases.
Teachers who had been rated just below 250 and returned for the 2011-12 school year increased their IMPACT scores by roughly 12.6 points more than teachers who had been rated at 250 and just above. That is, these teachers who faced a dismissal threat surpassed most of the teachers whose scores were just above the "effective" threshold and therefore did not face the same incentives. This gain in teacher performance is equivalent to moving a teacher from the 10th to the 15th percentile of the district's performance distribution. This gain is also similar to half of the performance gains observed among the district's novice teachers during their first three years in the classroom.
"Highly effective" teachers, who may have been motivated by the chance of earning a permanent pay increase if they maintained their rating for a second consecutive year, also showed a noticeable jump in their measured performance. According to the findings, they improved, on average, by roughly 10.9 IMPACT points, a gain equivalent to moving a teacher from the 78th to the 85th percentile of the district's performance distribution.
The researchers also found that dismissal threats shaped the district's teaching workforce through the voluntary attrition of low-performing teachers. Approximately 20 percent of the DCPS teachers who received a score just above the effective threshold rating for the 2010-11 school year did not return for the subsequent year. For the minimally effective teachers just below this threshold, the probability of not returning to the district's classrooms jumped to 31 percent, an increase of more than 50 percent.
In contrast, the study found that the base-pay incentives did not clearly increase the retention rates of highly effective teachers who were already retained at much higher rates than low-performing teachers.
"A key part of what makes these results compelling to us is our ability to credibly rule out alternative explanations. Our research design compares outcomes among teachers whose performance in the prior year happened to place them just above or just below the score thresholds that separate IMPACT's rating categories," said Dee. "In short, our study identifies the differences in outcomes between teachers who face sharp differences in performance incentives but who are essentially identical in all other respects. Thus, this research design allows us to isolate the effects of the incentives in IMPACT from the effects of differences in prior performance."
The study notes that the findings do not necessarily speak to those teachers who score away from the thresholds – those who are consistently scored as solidly "effective," for example.

Incentives and support

According to Dee and Wyckoff, these results are almost certainly about more than incentives alone. There have been a number of previous studies of financial incentive programs, including tests of pilot programs in Nashville, New York City and Chicago, and they have not yielded evidence of meaningful change in teacher performance. Some researchers speculate that those programs didn't offer big enough rewards and that they focused too narrowly on test scores rather than the instructional practices teachers can control more directly.
Dee and Wyckoff contend that the IMPACT program is a much better case study to determine whether more sophisticated performance assessments of teachers coupled with incentives are an effective strategy to motivate and retain high-quality teachers. IMPACT spans one of the nation's major urban school districts, features bigger pay incentives and focuses on the differential retention of high-performing teachers rather than only seeking to raise the performance of existing teachers. In addition, IMPACT, which is currently in its fifth year, has proven more durable than most teacher-compensation programs, so DCPS teachers are unlikely to view it as provisional policy.
"For these reasons, we viewed IMPACT as a uniquely powerful test. If the high-powered incentives and supports that IMPACT created didn't work during a sustained application, we would've viewed that as a nail in the coffin of this literature," Dee said.
While the researchers say the results should be encouraging for districts on the fence about implementing incentive programs, they also warn that IMPACT is not one size fits all.
"Perhaps most important are the implementation details that were coupled with these incentives," Wyckoff added. "IMPACT appears to have been comparatively successful in defining what teachers need to do in order to improve their scores and providing corresponding supports. Evaluations and incentives are likely to have little effect if teachers lack the knowledge and support to act on the information the evaluations provide."
"It's not easy for districts to develop and implement a system of this scale and sophistication," said Dee. He noted that the program includes data systems management, communications, careful training of raters on the district's structured rubrics and ongoing support of teacher improvement (for example, instructional coaches).
The researchers cautioned that if school districts push out lower performing teachers, they must also consider whom they hire to replace them. The study found that DCPS was able to recruit new teachers whose performance substantially exceeded the performance of those they replaced.
Funding for the study came from the Carnegie Corporation of New York and the National Center for the Analysis of Longitudinal Data in Education Research, or CALDER.


Designing Effective Knowledge Networks 10-17

Designing Effective Knowledge Networks

Reproduced from MIT Sloan Management Review

In today’s interconnected world, networks for sharing knowledge are increasingly important. By paying careful attention to eight dimensions of network design, leaders of knowledge networks can facilitate desired behaviors and outcomes.
“Knowledge networks” are collections of individuals and teams who come together across organizational, spatial and disciplinary boundaries to invent and share a body of knowledge. The focus of such networks is usually on developing, distributing and applying knowledge. For-profit and nonprofit organizations of all sizes are seizing on this model to learn more quickly and collaborate productively. However, for every successful network, others have lost steam due to poor participation, goal ambiguity, mixed allegiances or technology mismatches.


Knowledge networks are as old as human commerce, as knowledge was often implicitly exchanged in the production and exchange of goods and services. In the medieval days of guilds and apprentices, formal networks existed between artists, artisans and tradesmen. However, in recent years, Web-based collaboration has streamlined the identification and distribution of codified knowledge, at lower cost and over greater physical distance.1 In his classic 1937 article “The Nature of the Firm,” economist Ronald Coase predicted that companies would grow larger as information costs fell.2 Instead, we have witnessed less the rise of company size than the rise of intercompany collaborations. The knowledge network has been trumpeted as a model for innovation and scale — one that capitalizes on the agility and reach of human connections while integrating practical insight into the day-to-day work of network members. Networks can be 10 people across a handful of organizations or 1,000 people across continents and industries.

Knowledge network members come together around a common goal and share social and operational norms. Most researchers agree that network members participate out of common interest and shared purpose rather than because of contract, quid pro quo or hierarchy. However, researchers don’t agree about the importance of formal structure, organization and leadership. Some emphasize that members are simply “linked together by interdependent exchange relationships” while others call for formalized roles, routines and metrics.3 What’s clear is that knowledge network leaders can influence members’ behavior through network design and facilitation. And that can mean the difference between magnetism and fizzle, between knowledge sharing and hoarding, between inspiration and cynicism.

We sought to better understand the leverage that network leaders have. Much recent writing in both the academic and popular presses about knowledge networks has focused on their outcomes and products, such as knowledge diffusion, new knowledge creation, influence and intercompany and interpersonal connectivity.4 However, there is considerably less attention paid to how leaders systematically initiate and monitor members’ values and behaviors, for example, by reframing inherent conflicts of interest. The question we asked was: How do leaders balance emergent, voluntary “interdependent exchanges” with the practicalities of achieving goals?

Our initial research, funded by the Bill & Melinda Gates Foundation, focused on how knowledge networks could improve the spread of evidence about childhood and maternal nutrition. (See “About the Research.”) We used that research to develop a model of knowledge networks, and later validated our model in organizations outside the international health space. In that process, we developed case studies of ConocoPhillips, the world’s largest independent exploration and production oil company, and Women’s World Banking, a global nonprofit that operates in 28 countries and is dedicated to providing low-income women with access to financial tools and resources. These different examples provided a good test for the model: At ConocoPhillips, knowledge networks are an intermediate good, a means to an end and a vehicle to create products or drive efficiencies. At Women’s World Banking, the creation and diffusion of knowledge is the product — the value Women’s World Banking brings to market.

ABOUT THE RESEARCH
Our initial research for the Bill & Melinda Gates Foundation in 2011 studied how knowledge networks could improve the spread of evidence about childhood and maternal nutrition — across socioeconomic, political and geographic boundaries, and across academic, policy, health care and tribal practice domains.i Looking across the for-profit and nonprofit sectors, we asked network conveners, members, researchers and network participants how they negotiated the goals of their networks. We probed into which member behaviors resulted in the achievement of goals and which dynamics guided those behaviors. Finally, we asked what leverage leaders could have by explicitly designing to achieve these dynamics.

ConocoPhillips has more than 10,000 unique network members in multiple networks, yielding a membership of more than 30,000 in just over 100 global networks. Each network is purpose-driven, sponsored by functional leadership to connect employees to just-in-time insights on topics as diverse as production engineering and information technology solutions. “We realize that the future of our company will be born out of a web of human conversations,” explained Dan Ranta, ConocoPhillips’ director of knowledge sharing. “Connecting our knowledge workers purposefully gives our company a greater opportunity to create regular, sustainable business value.”

In 2009, Women’s World Banking launched the Center for Microfinance Leadership, with a mission to “develop principled and visionary leaders” for the microfinance industry.5 In 2012, Sarah Buitoni, the Center for Microfinance Leadership’s manager for alumni networks, launched the Women’s World Banking Leadership Community with seed funding from the Cisco Foundation. The goals were to improve the adoption of leadership approaches in the microfinance industry and to extend microfinance industry leaders’ support for each other as they “re-enter” their organizations after attending a training session or conference. “The ability to tap into and leverage a network of experts will drive our success in being responsive to leaders’ needs,” said Buitoni. “At the same time, this will enable us to continue to deliver high-quality programs and raise the bar across the microfinance industry on issues of leadership, governance and diversity.”

Four Knowledge Network Goals

Considerable research shows that unless goals are clearly stated and agreed upon, networks can easily lose energy and underperform.6 Even if network leaders develop and communicate these goals, this isn’t a guarantee that the goals can animate members. We wanted to know if specific purposes and named outcomes call for different network designs. Is the network’s primary purpose knowledge development (for example, through convening, brokering or funding knowledge creation) or the diffusion, scaling and absorption of ideas by knowledge network participants? Depending on the answer, what leadership model and convening process work best?

Answers by knowledge network leaders, consultants and researchers to these questions of designing for outcomes fall into distinct categories. We saw some network goals that were externally focused, collective and product-oriented — such as group coordination and knowledge-capital publication. And we saw some goals that were internally focused or individual-focused, such as problem solving, support of individuals, and member teams’ translation or adaptation into their local context. We discerned four distinct types of goals.

1. Coordination.

When coordination is a key goal, the network coordinates and leverages members’ existing knowledge activities through its structures, incentives and norms. For example, ConocoPhillips’ networks are focused on coordinating specific global practices, mainly in domains related to exploration and production. In one such network, an Australian operation identified a new technique for underwater tank inspections that a partner-operated facility in the North Sea adopted as well, resulting in a coordinated inspection approach that could be optimized across geographies.

2. Learning/Innovation.

When learning and innovation are important goals, the knowledge network commissions, accumulates and distributes knowledge for its members’ consumption, or as a general public good. Some learning is also inward-looking: The network learns systematically about itself and its processes. The Learning Innovations Laboratory, run by Harvard Graduate School of Education’s Project Zero, brings together chief learning officers across a wide variety of global organizations. Project Zero team members convene the knowledge network several times annually in Cambridge, Massachusetts (as well as asynchronously). The 25 chief learning officers in the network routinely explore changes in the landscape for corporate learning, experiment with new practices and return to their organizations to pilot new ideas gained from their participation in the network.7

Women’s World Banking introduced “project circles” for members to synthesize shared practices and artifacts, such as middle management competency models and “re-entry strategies” when alumni return to their organizations after attending a training or workshop. Co-created knowledge products are then published outside the community for public consumption.

At ConocoPhillips, network leaders move closed discussion items into the enterprise-wide wiki (called OneWiki), searchable from multiple network platforms. ConocoPhillips commissions special assignment teams, called workgroups, to solve specific issues, creating explicit practices that are then shared back with the networks.

3. Translation/Local Adaptation.

When translation and local adaptation are primary network goals, teams join the knowledge network to identify and adapt knowledge to their specific local challenges. By joining the network as a unit, they can safely vet and translate new or controversial ideas before returning to their home context. Teams improve their absorptive capacity when they become a “voting bloc.” They don’t simply remix or reframe ideas but become networks themselves, supporting each other back at home through their common experience and vocabulary. For example, Cambridge, Massachusetts-based Institute for Healthcare Improvement’s IMPACT communities are comprised not of individuals but of teams made up of nurses, administrators, physicians, project managers and pharmacists seeking to reduce medical errors and inefficiencies. By joining other teams and “taking off the white coats,” individuals exchange ideas and learning across hospital teams, unfettered by hierarchy. Setting aside the political trappings of rank and power, the team members are also able to reflect together on the relevancy or applicability of lessons about how to put IHI’s healthcare improvement methods into practice.8

ConocoPhillips often works on a regional team-based model, so team-driven translation comes naturally. For example, Canadian business unit members harvested ideas from the unconventional reservoirs network that was mainly working in the Eagle Ford geological formation area of South Texas. The Canadian business unit members attempted to announce those ideas to their local colleagues only after vetting them and adapting them to Canadian geological environments.

Similarly, Women’s World Banking’s Center for Microfinance Leadership is expanding its engagement with entire leadership teams through in-house leadership development programs. In the next phase of its Women’s World Banking Leadership Community, the Center is exploring how leadership teams that have engaged in those programs can capitalize on their new shared language to more rapidly have an impact at home.

4. Support of Individual Members.

When this is an important goal, individuals join the network to develop, accumulate and adapt knowledge to support their own and their colleagues’ work. Support of individual members is the most common goal of the corporate knowledge networks we examined. We also saw this strongly in the global health and development arenas. For example, Knowledge Management for Development, KM4Dev.org, founded in 2000, is an approximately 3,400-member virtual knowledge network that individuals in the international development field can join regardless of their organizational level or accomplishments.

Freedom for an individual to ask questions without manager scrutiny and peer criticism is a central goal of the knowledge network models for both ConocoPhillips and Women’s World Banking. In addition to individuals tapping the network for problem solving, Women’s World Banking has incorporated peer coaching into its network model. For example, two microfinance leaders from Jordan and from Uganda have peer-coached each other with daily check-ins on the topic of time management. ConocoPhillips, meanwhile, promotes network membership as part of the onboarding process for new employees; the company’s knowledge networks help new and experienced hires connect up and down the ConocoPhillips hierarchy from the start.

A Framework for Effective Knowledge Networks

Meeting any of the four goals of a knowledge network requires members to act by capitalizing on the cohesion, conversation and connectedness of the network. Those traits don’t just emerge out of thin air. We sought to understand the larger effects that influence knowledge network performance. Borrowing from the organizational learning field, we studied the knowledge network through the lens of what is called a leverage framework. (See “A Framework for Knowledge Network Effectiveness.”) First, we read the diagram from left to right to see the chain of influences (Design → Dynamics → Behaviors → Outcomes). Then, reading from right to left, we can peel back the layers that lead to the outcomes.

A FRAMEWORK FOR KNOWLEDGE NETWORK EFFECTIVENESS

View Exhibit

Outcomes

Outcomes can be described as meeting the four knowledge network goals of coordination, learning/innovation, translation/local adaptation and support of individual members. Depending on the context, the network achieves measurable change in the area of focus, whether that focus is revenue, operations, job satisfaction, learning, sustainability or profitability.

Behaviors

Behaviors are those that are conducive to outcomes: cohesion, demonstration of trust, connection sharing, using a common technology platform and making investments in collaboration, such as taking time out to answer fellow members’ questions. In a successful knowledge network, members identify with the network and its aspirations, readily share their connections inside and outside the network and are committed to moving knowledge sharing to the platform so that everyone can benefit. For example, ConocoPhillips’ network members use a discussion forum called “Ask & Discuss” to ask questions and conduct problem solving through the platform.

Dynamics

Dynamics are feedback loops, the systems and structures that sustain a given behavior. Dynamics can also be patterns of interaction with the outside world, such as reactions to market threats and incentives. For example, in our research for the Gates Foundation, we saw a “safety-absorption pattern” for new ideas: To gain uptake and spread health practices, members who were implementing the new practices needed first to safely inquire into and troubleshoot what they perceived to be translation obstacles. Similarly, members of the Women’s World Banking microfinance network, by participating over time in asynchronous online Alumni Circle discussions — and live Skype conversations — safely “try on” new leadership behaviors in the company of other members before taking those behaviors back to their microfinance institutions.

Design

Design encompasses the set of conditions that network leaders explicitly put in place to trigger those dynamics and, in turn, set behaviors into motion. Highly successful knowledge network leaders that we interviewed saw design as either positive leverage or an Achilles’ heel. They fluently traced disappointing outcomes through the layers of behaviors and dynamics and finally to an overlooked design component. They explained the relationships between design choices and the dynamics they sought and took pains to influence those dynamics. In fact, they saw themselves as social artists, continually tweaking the knowledge network design.

Designing Knowledge Networks for Success

Experienced knowledge network leaders that we interviewed endeavored to create a consistency between structures (such as operating model, charter and technologies) and strategy (such as purpose, network composition and learning context). They used visible performance information and incentives (such as reputation, recognition and sense of belonging) to inspire, motivate and redirect the behaviors of the members. We identified eight design dimensions of knowledge networks. (See “The Eight Design Dimensions of Knowledge Networks.”) The following eight dimensions cover the spectrum — from negotiating leadership to chartering, operating and adapting the network to changes in the social, economic, technical and political environment. (See “Knowledge Network Design Questions to Consider” for the questions to ask about each design dimension.)

THE EIGHT DESIGN DIMENSIONS OF KNOWLEDGE NETWORKS

View Exhibit

KNOWLEDGE NETWORK DESIGN QUESTIONS TO CONSIDER

Download Exhibit (PDF)

1. Leaders’ Shared Theory of Change.

Successful knowledge network leaders can describe the mechanisms through which network activities will have an impact on members and organizations. That is, they can state their theories of change. For example, they can state whether members respond and learn from written evidence or from visceral experiences. When they are able to discuss how the network mechanisms work, leaders (including core teams and sponsors) are well aligned and therefore act consistently with each other. They regularly discuss network designs and impacts, for example, choosing the mechanisms that are conducive to support network participants, intellectual capital development or coordination. The theory of change is included in a strategy or charter document.

This design dimension is as much about being explicit about how to have an impact as about how to be a leadership team. We found that good leaders were role models, inspiring members to act, and they did not delegate work such as being online and responding to discussions. They were routinely visible — as a cohesive team — to the community.

For example, ConocoPhillips senior leaders have gone on record endorsing cross-organizational knowledge sharing of their Networks of Excellence as critical to innovation in the company’s exploration and production process. While ConocoPhillips tends to designate senior practitioners and subject matter experts to guide the networks, it expects those leaders to routinely join the fray, answering posts and mentoring other members’ contributions in a moderator role.

At Women’s World Banking, humility and inclusion are basic ingredients in the leaders’ theory of change. For example, when a new cohort of leaders-in-training joined the organization’s Leadership Community four months after the network’s launch, founding member-leaders took the time to write on the “walls” of new members to welcome them to the community.

2. Objectives/Outcomes/Purpose.

Leaders help to define the network’s purpose and target outcomes. Outcomes can be solving a specific problem or combining forces and knowledge. They can be classified as one or more of the network goals described earlier, such as support of individual members. A charter or similar document lays out the network’s objectives and purpose, which need to be sufficiently crisp that members can state them. Objectives are best negotiated in a way that reflects the leaders’ shared theory of change and the goals themselves.

ConocoPhillips’ Networks of Excellence are formal, purpose-driven, global groups with clear coordination and process innovation agendas. Their charters are vetted and approved by senior functional management and must tie to larger global organizational metrics for productivity and innovation. Similarly, Women’s World Banking launched the design process of its Leadership Community by conducting consultations with microfinance leaders to determine which knowledge network goals resonated most closely with their needs and to model a core value and goal of the community — “leaders as experts and drivers of their own learning.”

3. Role of Expertise and Experimentation (also called the expert-learner duality).

Leaders need to be clear on how the network makes it safe for even the expert to be vulnerable and learn and for the learner to speak of bold possibilities. High-performing knowledge network leaders we interviewed thought deeply about how to trade off showcasing experts with supporting members who were stepping into the vulnerability of learning. The leaders did this with a deep understanding of the disparities of knowledge in their membership. For example, they had experts share and mentor, with learners asking questions where there were clear knowledge differences. Or in some cases they designed meetings (for example, using stories, questions or round robins) to set a tone of safety and encourage humility. When grandstanding or retreating occurred, leaders intervened appropriately.

To encourage participation, ConocoPhillips each year awards four Networks of the Year commendations to those networks that don’t just produce solutions but also achieve broad global participation across hierarchy levels. And in the Women’s World Banking Leadership Community, alumni of the Women’s World Banking Center for Microfinance Leadership participate in the community’s core team alongside Women’s World Banking staff — thus bridging the gap between expert, learner and convener. Community members also share stories of survival with one another, and in their interpretation of those experiences, community members play the roles of both expert and integrator.

4. Inclusion and Participation.

Knowledge network leaders position the knowledge network or network program among other operations or competing organizational models. The network’s core team explicitly defines what types of members they seek and actively recruits them. For example, they may seek out cognitive, geographical and professional diversity, or an amalgamation of separate social networks. They may seek to balance technical or operational expertise with convening or networking skills.9 Depending on the network goals, they may guard against having employees from competing companies, have new joiners approved by existing members or require joiners to come in teams.

For example, each ConocoPhillips network has a public profile for attracting members. Managers encourage employees to participate in multiple Networks of Excellence, and network leaders cross-post online discussions to extend the diversity of participation and the quality of problem solving.

By contrast, Women’s World Banking’s network includes “Alumni Circles” that are private, in order to enable senior leaders to freely share challenges they face within a trusted group. However, when posting resources on matters pertaining to the whole community, members may (and often do) share knowledge assets outside the Alumni Circles, for the benefit of all network members.

5. Operating Model.

Knowledge network leaders decide what roles, responsibilities and decision processes are needed for optimal network operations. All stakeholders, including the public, should be described in the operating model, and there should be clarity about how resources are allocated. For example, there may be core team members (including managers of content, membership, events or measurement) as well as small project teams or working groups that assemble for just a few months to complete a task. Typical projects for working groups might involve integrating viewpoints, conducting a survey or drafting a policy. Operations over time are expected to change. The core leadership team may rotate to add fresh ideas and reduce burnout. Schedules are published and tracked.

Operating models for each of the four knowledge network goals could be quite different. Where coordination is critical, core team membership could include representatives of each organization. Where the emphasis is on the individual practitioner’s learning, the operating model may have more roles and more rotations to expand individuals’ learning and social capital. Where the emphasis is on creation of intellectual capital, content manager and synthesizer roles are critical. Where translation by teams of local change agents is crucial, there may be a formal representative of each organization who seeks to take ideas home.

ConocoPhillips’ operating model includes executive sponsorship by functional leaders, network leadership through a core team and support from a centralized support team. Network processes balance ad hoc knowledge sharing with more explicit innovation, authoring and publishing.

At Women’s World Banking, the Leadership Community governing group includes the organization’s grantor (Cisco), network member-leaders and a support team. The support team prepares meeting topics, onboards new members, plans platform improvements and posts training content from the Center for Microfinance Leadership programs.

6. Convening Structures and Infrastructures.

Network leaders understand how online and real-time or live convenings serve to build cohesion, connectivity, collaboration and engagement. Core network teams may develop a matrix proposing what channels or vehicles are used for what purpose and with what members. In our research for the Gates Foundation, we found that despite much excitement about social media and collaboration portals, network leaders and researchers named real-time human connections (meetings, conference calls, video teleconferences) as prerequisites for trust building and knowledge sharing. This is consistent with recent research that found that teams’ performance correlated directly to the frequency and variety of real-time interactions.10 The degree of face-to-face and voice-to-voice interaction depends on the network objectives. Rapid idea development and innovation require live discussions (online or in meetings), while intellectual capital management requires document management and broadcast communication.

Network leaders look for evidence of success or failure in network participation, as well as ways to incentivize people to join, participate and engage.
ConocoPhillips’ collaboration platforms have both document sharing and social functionality such as discussions, activity feeds, wikis, chat and notifications. The company emphasizes the text-based, asynchronous mode of communication, which the company’s network leaders call “the great equalizer” for people for whom English is a second language. Increasingly, ConocoPhillips is bringing the network to the members, rather than making members go out to a network platform. The company is using a feed of knowledge network content in day-to-day process applications, such as purchasing. Semantic analysis of users’ work (predicting what content users are more likely to access and reuse) is shortening search and browse times on network platforms.

Women’s World Banking built a collaboration website where members discuss topics, share documents, read activity feeds and collaborate on wikis, chats and discussions. The nonprofit has placed a strong emphasis on real-time interaction, using Skype to enable leaders to speak directly to each other. The organization strives to align diversity of technology with member diversity. “Technology allows learning to continue well after an in-person training,” said Charu Adesnik, corporate affairs manager at Cisco. “The [Women’s World Banking] Leadership Community is drawing together a diverse set of microfinance leaders who now have a global platform to share best practices and access resources that improve the impact of their services.”

7. Facilitation and Social Norm Development.

Knowledge network leaders take on the roles of facilitators and change agents, not just project managers. They convene members in meetings, discussions, games, events and other interactions to draw out their hidden insights or to provoke a common curiosity.11 In high-performing networks, network leaders agree about how to model and develop positive interactions within the network. Social norms — such as inclusion, openness, transparency, accountability, curiosity and quality — are integrated explicitly into the facilitation processes. For example, respect for diversity could be conveyed in the tone and language of meeting agendas, discussions, blogs and quick polls.

The core team members for ConocoPhillips’ networks are asked to prod discussions, periodically nudging, playing back or “translating,” in addition to asking probing questions. In network leader Ranta’s words, they draw out the “know-how, know-what and know-why” to help others solve problems and learn. Women’s World Banking Community administrators, meanwhile, play a clear convening role but draw on members to act as facilitators of Skype calls and webinars, thereby modeling the network’s norm that network participants own the agenda.

8. Measurement, Feedback and Incentives.

Network leaders look for evidence of success or failure in network participation, as well as ways to incentivize people to join, participate and engage. One goal is to signal to outsiders and sponsors that the network is effective. Metrics must be credible and appropriate in terms of effort and relevance. Network performance metrics are elusive, as outcomes are often felt at the members’ home organizations and thus are separated in space and time from inputs like discussion participation. Leaders address these delays between knowledge network behaviors and impacts by having a map that shows the pathway between inputs and outcomes. There are clear checkpoints during the monthly or quarterly schedule when network leaders look at performance data and look at improvements to plans. Incentives include the extrinsic (community celebrations or letters or appreciation directed to managers or network members) as well as the intrinsic (learning something new or solving a problem quickly). High-performing network leaders manage to minimize bureaucratic review and tie performance to incentives quickly so that members feel pride, connection and even healthy competition.

ConocoPhillips routinely publicizes the business impacts of its Networks of Excellence. For example, recall the anecdote mentioned earlier about how a North Sea business unit adopted a technique for underwater tank inspection from an Australian business unit. The company also publishes input statistics, such as membership and discussion posts, as well as numbers of published lessons learned. Network participation and knowledge-sharing rates roll up to functional and business unit performance metrics, which link to a discretionary portion of ConocoPhillips employees’ variable compensation. Ranta is clear on this issue: “If you are not in a network that can help your work, or if you are not active, you are not contributing to the greater good of the company.”

The Importance of Knowledge Network Design

In his foreword to a 2011 United Nations publication called “Networks for Prosperity,” Jan Wouters, director of the Leuven Centre for Global Governance Studies at KU Leuven, wrote: “Networks, formal and informal, local and global, are increasingly important channels for pursuing policy goals in a globalizing world.”12 Knowledge networks are clearly vital to our connected world. Yet our research indicates that we, as leaders, must be thoughtful about how we design and manage them. Though much network behavior is emergent, the way network leaders catalyze action makes a difference. The network effectiveness framework and, in particular, the eight design dimensions offer a holistic approach for achieving collaboration, network cohesion and broad connectivity — which, in turn, help yield the important outcomes of coordination, learning/innovation, translation/local adaptation and participant support
