This paper reports the results of a laboratory experiment on network formation among heterogeneous agents. The … experimental design extends the basic Bala-Goyal (2000) model of network formation with decay and two-way flow of benefits by … network has a star structure. We find that with homogeneous agents, equilibrium predictions fail completely. In contrast, with …

We present an economic experiment on network formation, in which subjects can decide to form links to one another … Goyal (2000). They distinguish between two scenarios regarding the flow of benefits through a network, the so-called 1-way … asymmetry, i.e., payoff inequity, plays an important role in the network formation process. …

Workers are embedded within a network of social relationships and can communicate through word-of-mouth. They can find …. We show that, when the network size increases, on average, the unemployed workers hear about more vacancies through their … social network but, at the same time, it is more likely that multiple vacancies reach the same unemployed worker. Above a …

We provide some of the first rigorous evidence on performance spillovers and social network in the workplace. The data … network. Specifically rural low-ability weavers are found to improve their performance as their high-ability teammates (who …

Then, using network econometrics, we show that the observed … homophily is not only an outcome of endogenous network formation, but is also a result of friends influencing each others … other demographic characteristics (Jackson, 2010). We present novel evidence on an understudied source of homophily, namely …
