This paper proposes a method for implementing counterfactual experiments in estimated models that have multiple equilibria. The method assumes that the researcher does not know the equilibrium election mechanism and wants to impose minimum restrictions on it. Our key assumption is that the...

In a hub-and-spoke network, the total profit function of an airline is supermodular with respect to its entry decisions at different city-pairs. This source of complementarity implies that a hub-and-spoke network can be an effective strategy to deter entry of competitors. This paper presents a...

Empirically studying dynamic competition in oligopoly markets requires dealing with large states spaces and tackling difficult computational problems, while handling heterogeneity and multiple equilibria. In this paper, we discuss some of the ways recent work in Industrial Organization has dealt...

The development of two-step econometric methods for dynamic structural models has afforded researchers the ability to estimate models with large state spaces without having to compute a full solution of the model even once. However, regardless of the method used for estimation, the...

The Riegle-Neal Act in 1994 established the conditions for the removal of restrictions on interstate banking and branching in US. One of the primary motivations for enacting this act was permitting banks to diversify geographic risk. The purpose of this paper is to study the role of...

We propose a dynamic model of an oligopoly industry characterized by spatial competition between multi-store retailers. Firms compete in prices and decide where to open or close stores depending on demand conditions and the number of competitors at different locations, and on location-specific...

type="main" xml:lang="en" <p>This paper evaluates the effects of a labor market reform in Spain that removed restrictions on fixed-term or temporary contracts. Our empirical results are based on longitudinal firm-level data that cover observations before and after the reform. We posit and estimate...</p>

We derive marginal conditions of optimality (i.e., Euler equations) for a general class of Dynamic Discrete Choice (DDC) structural models. These conditions can be used to estimate structural parameters in these models without having to solve for or approximate value functions. This result...

We survey the recent empirical literature on structural models of market entry and spatial competition in oligopoly retail industries. We start with the description of a framework that encompasses various models that have been estimated in empirical applications. We use this framework to discuss...
