We propose a Walrasian explanation for the existence of fixed prices, i.e., of trades in which either the price or the quantity exchanged do not reflect all publicly available information. Such trades result in a rigid price system that facilitates the sharing of social risks; they may also...

We study the selection of an equilibrium for coordination games: symmetric, simultaneous move, complete information games which have multiple, Pareto-ranked Nash equilibria. We design and experiment to explore regularities in the observed outcomes for this class of games. With replication, we...

Regular consumer demand systems almost invariably employ specifications that involve common functional forms in all equations. When applications involve crosssectional data it is often the case that demographic effects are important. However it is plausible that demographic effects are...

This paper studies hours, employment, vacancies and unemployment at micro and macro levels. It is built around a set of facts concerning the variability of unemployment and vacancies in the aggregate and, at the establishment level, the distribution of net employment growth and the comovement of...

This paper investigates the dynamic behavior of an economy with multiple Nash equilibria. The first part of the paper analyzes an abstract game exhibiting multiple equilibria. A history dependent selection criterion is proposed which induces correlated behavior in equilibrium even though agents...

We study labor adjustment costs. We specify a dynamic optimization problem at the plant-level, allowing for both convex and non-convex adjustment costs. We estimate the parameters of the adjustment process using an indirect inference procedure in which simulated moments are matched with data...
