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 …

-in-means model where each individual has his own specific reference group. Interactions are thus structured through a social network … exogenous effects are generally identified under network interaction, although identification may fail for some particular … structures. Monte Carlo simulations provide an analysis of the effects of some crucial characteristics of a network (i …

We employ a standard identification strategy from the peer effects literature to investigate the importance of network … Survey (Add Health) to construct two network definitions that are less ad hoc than the school-grade cohorts commonly used in … the educational peer effects literature. We demonstrate that accurate definitions of the peer network seriously impact …

When agents can … choose geographic locations, there is a tendency for those who are more central in the social network to locate closer to the …

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.
