The Telecommunications Act of 1996 (the "1996 Act"), by stressing the reduction or elimination of entry barriers that prevent the fragmentation of market structure and an increase in the number of competitors, established competition and deregulation as the foundation for public policy towards...

This paper evaluates how different lengths of entry regulation impact market structure and market performance using a dynamic structural model. We formulate an oligopoly model in the tradition of Ericson and Pakes (1995) and allow entry costs to vary over time. Firms have the opportunity to...

We focus on the estimation of market entry costs that are declining over time and evaluate their impact on competition and market performance. We employ a dynamic oligopoly model in which firms make entry, exit, and production decisions in the presence of declining entry costs and learning by...

We examine a variant of Hotelling model where prices and locations are fixed but quality is a choice variable. We show that when sellers of a horizontally differentiated product are price-constrained and compete in quality, entry can lead to degradation of quality offered in equilibrium and...

In this paper, we review the literature on declining business dynamism and its implications in the United States and propose a unifying theory to analyze the symptoms and the potential causes of this decline. We first highlight 10 pronounced stylized facts related to declining business dynamism...

Ease of entry is crucial to well-functioning electricity markets. This paper investigates the patterns of entry in the generation segment of the electricity industry of OECD countries and seeks to provide an understanding of their key determinants. It aims to derive implications for the design...

Empirical studies have found high correlation between entry and exit across industries, indicating that industries differ substantially in their degree of firm turnover. I propose a computational model of dynamic oligopoly with entry and exit in a turbulent technological environment. I examine...

In many settings where spatial preemption might be expected to produce tightly concentrated industry structures, firms share the market instead. Using a strategic investment model, I show that this can be rationalized by heterogeneous brand preferences, which cause new product introductions by...
