Models of spatial competition are typically static, and exhibit multiple free-entry equilibria. Incumbent firms can earn rents in equilibrium because any potential entrant expects a significantly lower market share (since it must fit into a niche between incumbent firms) along with fiercer price...

In this article we propose an innovative way of delineating geographical markets based on easily accessible data. We apply this concept for the day care industry and investigate providers' location choices relative to local market characteristics to evaluate the widespread presumption that local...

This paper empirically examines the impact of entry by Wal-Mart on competition in the supermarket industry. Using a detailed panel dataset spanning 1994 to 2006, we estimate the impact of Wal-Mart on firm outcomes and market structure, controlling for persistent local trends and systematic...

We study the relationship between market size and a number of firms in several healthcare professions in Slovakia to provide a new evidence about their entry decisions and a toughness of competition in the market. The size of a local market to support the entry of the first general practitioner...

We investigate private and social incentives for standardization to ensure market-wide system compatibility in a two-dimensional spatial competition model. We develop a new methodology to analyze competition on a torus and show that there is a fundamental conflict of interest between consumers...

Using data about all de novo entrants into Canadian manufacturing sectors during 1984-1998, we studied location choices as a function of firms' initial resources and capabilities. Employing nested logit estimation, we examined the impact of various location traits such as: agglomeration,...

In merger analysis and other antitrust settings, risk is often cited as a potential barrier to entry. But there is little consensus as to the kinds of risk that matter- systematic versus non-systematic and industry-wide versus firm-specific - and the mechanisms through which they affect entry. I...

We revisit the relationships between competition and various market outcomes in a differentiated Cournot oligopoly. Consider an oligopolistic market with two differentiated varieties, where each firm sells one of the varieties. We show that social welfare and consumer surplus can decrease with...
