We study firms' incentives to create switching costs using a four-period model consisting of two consecutive price-competing stages intervened by options to create switching costs early (before price competition) and late (during price competition). Acknowledging that many real/social switching...

Entrants are typically found to be more innovative than incumbent firms. Furthermore, these innovative ideas often originate with established firms in the industry. Therefore, the established firm and the start-up firm seem to select different types of projects. We claim that this is the...

This paper reviews a framework for numerically analyzing dynamic interactions in imperfectly competitive industries. The framework dates back to Ericson and Pakes [1995. Review of Economic Studies 62, 53–82], but it is based on equilibrium notions that had been available for some time before,...

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...

We provide a general model of dynamic competition in an oligopolistic industry with investment, entry, and exit. To ensure that there exists a computationally tractable Markov perfect equilibrium, we introduce firm heterogeneity in the form of randomly drawn, privately known scrap values and...

The degree of collusiveness of a market with consumer switching costs is studied in an infinite-horizon overlapping-generations model of duopolistic competition. In contrast to previous models of switching costs, this paper assumes that firms compete for the demand for a homogeneous good by...

An economy is considered in which new firms require time to learn whether they will grow in size and profitability in the long run. The labor market is imperfectly competitive. I show that inefficient levels of firm entry will generally exist. Whether under or over entry occurs is tightly...
