Early results of evolutionary game theory showed that the risk dominant equilibrium is uniquely selected in the long run under the best-response dynamics with mutation. Bergin and Lipman (1996) qualified this result by showing that for a given population size, the evolutionary process can select...

What is the effect of imports on productivity? To answer this question, we estimate a structural model of producers using product-level import data for a panel of Hungarian manufacturing firms from 1992 to 2001. In our model with heterogenous firms, producers choose to import or purchase...

We build a model of social capital in networks based on repeated interactions. The strength of a relationship in part derives from the value of transactions it enables in the future. We show that shocks can be amplified through a network multiplier, because trust withdrawal that constrains...

double-counting.

We present a theory of individual choice in which the decisionmaker focuses more on, and hence weights more heavily, attributes on which the options in her consideration set are more different. Consistent with evidence on salience in monetary choices, our model predicts that the decisionmaker is...

We seed noisy information to members of a real-world social network to study how information diffusion and information aggregation jointly shape social learning. Our environment features substantial social learning. We show that learning occurs via diffusion which is highly imperfect: signals...

The present paper investigates the portfolio allocation decisions of an investor with infinite horizon when available financial assets differ in their degrees of liquidity. A model with risk neutral agents allows us to endogenously determine the liquidity premium. With risk averse agents, we...
