This paper estimates a model of airline competition that captures the two major features of the industry: product differentiation and economies of density. The results not only provide support to some of the traditional common wisdom in the industry, but are also useful for understanding major...

This paper focuses on how changes in the economic and regulatory environment have affected production costs and product characteristics in the automobile industry. We estimate cost functions characteristics. Then we examine how this cost surface has changed over time and how these changes relate...

This paper develops new techniques for empirically analyzing demand and supply in differentiated products markets and then applies these techniques to analyze equilibrium in the U.S. automobile industry. Our primary goal is to present a framework which enables one to obtain estimates of demand...

In this paper, we exploit new sources of cross-sectional data to estimate a detailed product-level demand system for new passenger vehicles. We use four data sources: on the characteristics of products, on the attributes of the U.S. population of households, on the match between the first and...

The U.S. airline industry went through tremendous turmoil in the early 2000's. There were four major bankruptcies and two major mergers, with all legacy carriers reporting a large profit reduction. This paper presents a structural model of the airline industry, and estimates the impact of demand...

This paper considers the problem of estimating the distribution of payoffs in a discrete dynamic game, focusing on models where the goal is to learn about the distribution of firms' entry and exit costs. The idea is to begin with non parametric first stage estimates of entry and continuation...

We consider identification of nonparametric random utility models of multinomial choice using "micro data," i.e., observation of the characteristics and choices of individual consumers. Our model of preferences nests random coefficients discrete choice models widely used in practice with...

In May, 1981, a voluntary export restraint (VER) was placed on exports of automobiles from Japan to the United States. As trade policies go, this one was important. At about the same time, though to much less fanfare, international trade theorists were obtaining (then) startling results from...

We consider the invertibility of a nonparametric nonseparable demand system. Invertibility of demand is important in several contexts, including identification of demand, estimation of demand, testing of revealed preference, and economic theory requiring uniqueness of market clearing prices. We...

Recent technological changes may have altered the balance between technology and copyright law for digital products. While file-sharing has reduced revenue, other technological changes have reduced the costs of bringing creative works to market. As a result, we don't know whether the effective...
