Many economic studies find market concentration positively related to profits. The findings may be explained either by oligopoly behavior or by greater efficiency of firms with large market shares

An analytical model is employed to investigate competitive markets characterized by asymmetric consumer information as to product quality. Support is found for Leland's conclusion [1979] that a

Regulators often confront the question of whether they should allow a regulated firm to vertically integrate. The relevant policy concerns are whether the downstream price will rise from the vertical

This paper provides a formal treatment of how vertical integration may deter entry "by reducing rivals' revenues". We examine a spatial market with the locations of firms fixed due to location

Based on the concept of weakly separable utility (which applied empirical work implicitly or explicitly assumes), this paper develops a theoretical condition that a set of own and cross-elasticity of

This note compares the efficiency of a joint venture with supply, output royalty and lump sum arrangements in the context of firms contributing complementary inputs to some project. In a world of

Price conjectural variations are estimated to measure the degree of price competition in a product differentiated oligopoly. The empirical model is a simultaneous equation system of product demand and

This paper compares two econometric methods that have been proposed for market definition: price correlations and residual demand curve estimation. Econometric theory is used to demonstrate that price
