When workers send applications to vacancies they create a network. Frictions arise because workers typically do not … friction affects network formation, while the second coordination friction affects network clearing. We show that those … that can arise and the number of matches on a given network. Equilibria that exhibit wage dispersion are inefficient in …

We explore network effects on generosity for different network dimensions. To this end we elicit multiple network … matters for friendship ties but that structural network variables are important in all network dimensions. Importantly, these … effects are not invariant across different network dimensions. We also find that individual characteristics are unrelated with …

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 …

We develop and estimate a theory-consistent gravity model for interregional migration flows in the presence of … equation for bilateral mobility that embodies a co-determined local unemployment term. As a theory of migration, our model …

We specify and implement a test for the importance of network effects in determining the establishments at which people … importance of network effects for groups broken out by race, ethnicity, and various measures of skill, for networks generated by …
