Search models with wage posting and match-specific heterogeneity generate wage dispersion. Given K values for the match-specific variable, it is known that there are K reservation wages that could be posted, but generically never more than two actually are posted in equilibrium. What is unknown...

Abstract We develop a two-country, two-currency, search-theoretic model of monetary exchange, extending previous such models by endogenizing prices using bargaining theory. We analyze features of the environment that make it more likely that a given money circulates internationally. We show the...

We analyze models where agents search for partners to form relationships (employment, marriage, etc.), and may or may not continue searching for different partners while matched. Matched agents are less inclined to search if their match yields more utility, and also if it is more stable. If one...

This paper generalizes Rubinstein and Wolinsky's model of middlemen (intermediation) by incorporating production and search costs, plus more general matching and bargaining. This allows us to study many new issues, including entry, efficiency and dynamics. In the benchmark model, equilibrium...

Are financial intermediaries inherently unstable? If so, why? What does this suggest about government intervention? To address these issues we analyze whether model economies with financial intermediation are particularly prone to multiple, cyclic, or stochastic equilibria. Four formalizations...

The generation and implementation of ideas, or knowledge, is crucial for economic performance. We study this process in a model of endogenous growth with frictions. Productivity increases with knowledge, which advances via innovation, and with the exchange of ideas from those who generate them...
