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 etimates of entry and continuation...

We provide an asymptotic distribution theory for a class of Generalized Method of Moments estimators that arise in the study of differentiated product markets when the number of observations is associated with the number of products within a given market. We allow for three sources of error: the...

This paper is a revised version of a keynote address delivered at the inaugural International Industrial Organization Conference in Boston, April 2003. I argue that new econometric tools have facilitated the estimation of models with realistic theoretical underpinnings, and because of this, have...

Atlanta's rail rapid transit system (MARTA), which began operations in 1979 and has cost U.S. taxpayers and residents of the Atlanta metropolitan area more than $3.5 billion (1990s), has been identified by advocates of new rail systems in other U.S. cities as one of the most successful rail...

This paper solves numerically the intertemporal consumption and portfolio choice problem of an infinitely-lived investor who faces a time-varying equity premium.

Optimal growth theory is sometices used to motivate green accounting by interpreting the "linearized" Hamiltonian at the present time as a proxy for an inclusive measure of NPP. A linearized Hamiltonian, is, in effect, an affine transformation of the utility function that makes consumption be...

Empirical work relating trade liberalization and income distribution has identified an important anomaly. The Stolper-Samuelson theorem predicts that trade liberalization will shift income toward a country's abundant factor. For developing countries, this suggests liberalization will principally...

This paper contains the first results from a monster study of more than 1.8 million Taxas elementary school students. The principal focus of the larger study is the impact, if any, of growing minority access to suburban schools on the performance of minority students on standardized achievement...
