We consider nonparametric identification in models of differentiated products markets, using only market level observables. On the demand side we consider a nonparametric random utility model nesting random coefficients discrete choice models widely used in applied work. We allow for...

High-quality producers in a vertically differentiated market can reap superior profits by charging higher prices, selling greater quantities, or both. If qualities are known by consumers and production costs are constant, then having a higher quality secures the producer both higher price and...

When a firm forms a market closes. Resources that were previously allocated via the price system are allocated by managerial authority within the firm. We explore this choice of organizational form using a model of price formation in which agents negotiate prices on behalf of their principals...

This is an invited chapter for the forthcoming Volume 4 of the Handbook of Industrial Organization. We focus on "selection markets," which cover markets in which consumers vary not only in how much they are willing to pay for a product but also in how costly they are to the seller. The chapter...

This paper investigates the drivers of support for market mechanisms (competition and optimizing behavior by agents). We elicit such attitudes using concrete and simplified situations where respondents face a tradeoff between an economically efficient situation and a pro-social objective. We...

This paper has a simple goal, that of understanding the joint behaviorof prices and quantities in a particular market. More precisely, it examines whether we can find decision problems for suppliers and buyers, together with a market equilibrium structure, which are consistent with the observed...

This study explores empirically the price dynamics within two distinct market institutions - a double oral auction, which resembles modern asset markets, and a bilateral exchange market, which represents markets that have existed for centuries. To provide a theoretical basis to our...

We develop a competitive equilibrium theory of a market for votes. Before voting on a binary issue, individuals may buy and sell their votes with each other. We define the concept of Ex Ante Vote-Trading Equilibrium, identify weak sufficient conditions for existence, and construct one such...

We complete the study of comparative statics initiated in Caplin and Leahy [2010], which introduced a new mathematical apparatus for understanding NTU allocation markets, as such covering the housing market and other markets for large indivisible goods. We introduce homotopy methods to...

In recent years, cases in which state governments chose to override federal environmental regulation with tighter regulations of their own have become increasingly common, even for pollutants that have substantial spillovers across states. This paper argues that this change arose at least in...
