In this paper we show that existence of a Markov perfect equilibrium (MPE) in the Ericson & Pakes (1995) model of dynamic competition in an oligopolistic industry with investment, entry, and exit requires admissibility of mixed entry/exit strategies, contrary to their assertion. This is...

The conventional wisdom in economic theory holds that switching costs make markets less competitive. This paper challenges this claim. We find that steady-state equilibrium prices may fall as switching costs are introduced into a dynamic pricing model. To assess whether this finding is of...

In this paper we analyze tax and transfer choices in an OLG economy with capital accumulation and endogenous growth coming from public investment, such as education. We solve for a Markov perfect equilibrium when electoral competition targets the votes of young and old households. We find that...

We study a standard quantitative model of sovereign default in which the government in a small open economy (SMO) decides how much to save and whether to default on its debt. In contrast with previous quantitative studies, we do not assume that a defaulting country is exogenously excluded from...

We examine pricing strategies for a multiproduct monopolist. We show that simple quantity discounting strategies are almost as profitable as fully optimal bundling. We investigate this in an empirical example, using data from a theater company

This paper explains market turbulence, such as the recent dotcom boom/bust cycle, as equilibrium industry dynamics triggered by technology innovation. When a major technology innovation arrives, a wave of new firms implement the innovation and enter the market. However, if the innovation...
