This paper develops an econometric model of industry dynamics for concentrated markets that can be estimated very quickly from market-level panel data on the number of producers and consumers using a nested fixed-point algorithm. We show that the model has an essentially unique symmetric...

Abstract: This paper develops an econometric model of industry dynamics for concentrated markets that can be estimated very quickly from market-level data on demand shifters and the number of producers. We show that the model has an essentially unique symmetric Markov-perfect equilibrium that...

The aim of this paper is to survey the recent empirical IO literature analysing differentiated products markets. The focus is restricted to the discrete choice approach that is carefully described and some recent applications of the full random coefficients model are analysed. The full random...

In this paper I analyze the kind of behavior which can be considered evolutively stable in an oligopolistic market

This paper discusses how numerical techniques may be used to solve the simultaneous functional equations that arise in general dynamic stochastic games. Unlike the conventional linear-quadratic approach, our methods may be used to address general model specifications that may include...

This paper studies the diffusion of a new technology that is brought to market while its potential is still uncertain. We consider a dynamic game in which an incumbent and a startup firm improve both a new and a rival old technology while learning about the relative potential of both...

Se estudia la evolución de la competencia en el mercado español de electricidad, proponiendo un análisis mediante teoría de juegos. Se elabora un modelo basado en juegos dinámicos siguiendo el concepto de Equilibrio Perfecto de Markov, tomando como bloque elemental una descripción de la...

Capacity addition and withdrawal decisions are among the most important strategic decisions made by firms in oligopolistic industries. In this paper, we develop and analyze a fully dynamic model of an oligopolistic industry with lumpy capacity and lumpy investment/disinvestment. We use our model...

This paper studies oligopolistic markets with differentiated products, with endogenous union structures and quality improvement-R&D investments. In the context of a dynamic game-theoretic analysis we investigate the conditions under which firm-level unions may strategically collude, or not, and...
