We extend the analysis carried out by Valletti (2000) by considering an environmental externality in a vertically differentiated duopoly where firms compete à la Cournot with fixed costs of quality improvement.We show that, if the weight of the external effect is high enough, the resulting...

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...

This analysis of global competitiveness of emerging market economies accounts for non-price aspects of competitiveness. Building on the methodology pioneered by Feenstra (1994) and Broda and Weinstein (2006), we construct an export price index that adjusts for changes in the set of competitors...

Building on the methodology pioneered by Feenstra (1994) and Broda and Weinstein (2006), we construct an export price index that adjusts for changes in the set of competitors (variety) and changes in non-price factors (quality in a broad sense) for nine emerging economies (Argentina, Brazil,...

Why are higher quality niches seen as intrinsically more profitable in business circles? Why do high quality products sometimes have a low real price, while it is unusual to see low quality products with high real prices? Can markets have quality differentiation as well as quality bunching? In...

We investigate how price ceilings and floors affect outcomes in continuous time, double auction markets with discrete goods and multiple qualities. When price controls exist, the existence of competitive equilibria (the solution concept of classical market theory) is no longer guaranteed; hence, we...

This paper considers horizontal merging decision under price and quality competition and examines whether two competing firms should merge and which merging strategy (i.e., centralized or decentralized merger) is optimal. Although horizontal mergers are prevalent in practice and have been...
