There is a large and diverse body of evidence that people condition their behavior on the characteristics of others. If type is visible then one agent seeing another with whom they are interacting, or observing some other close proxy for type, can affect outcomes. We explore the economics of...

We use a unique, new, database to examine micro depositor level data for a bank that faced a run. We use minute-by-minute depositor withdrawal data to understand the effectiveness of deposit insurance, the role of social networks, and the importance of bank-depositor relationships in influencing...

In social and economic networks linked agents often share additional links in common. There are two competing explanations for this phenomenon. First, agents may have a structural taste for transitive links -- the returns to linking may be higher if two agents share links in common. Second,...

The factors leading individuals to immigrate to developed nations are widely studied, but comparatively less is known about those who emigrate from them. In this paper, we use data from a nationally representative cohort of Australian adults to develop longitudinal measures of emigration and to...

We document that individuals who grew up in areas with high density of firms are more likely, as adults, to become entrepreneurs, controlling for the density of firms in their current location. Conditional on becoming entrepreneurs, the same individuals are also more likely to be successful...

We design a laboratory experiment to investigate bilateral link formation in a setting where payoffs are pair-specific. Our link formation rule is decentralized and players can make link offers and counter-offers, as in a Beckerian marriage market. The game is designed in such a way that a...

Agents often use noisy signals from their neighbors to update their beliefs about a state of the world. The effectiveness of social learning relies on the details of how agents aggregate information from others. There are two prominent models of information aggregation in networks: (1) Bayesian...

Referred workers are more likely than non-referred workers to be hired, all else equal. In three field experiments in an online labor market, we examine why. We find that referrals contain positive information about worker performance and persistence that is not contained in workers' observable...
