We investigate costly yet futile attempts at self-control when consumption of a harmful product has a binary breakdown/no-breakdown nature and individuals tend to underestimate their need for self-control. Considering time-inconsistent preferences as well as temptation disutility, we show that...

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...

Early results of evolutionary game theory showed that the risk dominant equilibrium is uniquely selected on the long run by 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 any...

We estimate a model of importers in Hungarian micro data and conduct counterfactual policy analysis to investigate the effect of imports on productivity. We find that importing all foreign varieties would increase firm productivity by 12 percent, almost two-fifths of which is due to imperfect...

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...
