We consider a simple model of market structure determination with discrete product differentiation and strategic interaction between firms. Our equilibrium concept is based on a set of relatively weak conditions that describe the profits of active and potential firms in a market. In our model,...

Despite the pervasiveness of industry regulation, there are few studies of its impact on industry productivity. Assessing regulation's impact on productivity has been difficult for a number of reasons, including the complexity of regulations and the difficulty measuring productivity. We study an...

We provide a framework for inference in discrete games that involve multiple decision makers and use it to study airline market structure in the US. We make inferences on a ``class of models'' rather that looking for point identifying assumptions that pin down a unique model. We extend the...

This paper studies the economics of intellectual property transfer using new data on the transfers of patents. We first present evidence about how the transfer and the expiration of patents relate to age, patent citations received, whether the patent has been previously traded or not, and the...

We propose a method for point estimation of discrete games similar to those considered by Bresnahan and Reiss (1991). In the model, the vNM utilities are a function of observed co-variates and random preference shocks. The model also explicitly parametrizes the probability of selecting a given...

We describe a two-step algorithm for estimating dynamic games under the assumption that behavior is consistent with Markov Perfect Equilibrium. In the first step, the policy functions and the law of motion for the state variables are estimated. In the second step, the remaining structural...

The purpose of this paper is to develop a framework that allows one to distinguish between the extent to which differences in firm productivity are intrinsic and the proposition that higher paying firms employ more able workers. For this purpose, we adapt the equilibrium stochastic model of firm...

We consider sufficient conditions for uniqueness in two-sided matching models with transfers. We analyse the strategy-proofness of allocation mechanism
