In this paper we study price competition, equilibrium market configurations and entry when firms compete in vertically-di¤erentiated markets producing complementary goods. We consider two complements and start from a configuration where the market for one complement is a duopoly, whereas the...

We study reactions to entry in a Cournot model, contrasting the case where firms are endowed with unchangeable technologies against that where technologies are flexible. By the latter we mean that firms can change the installed production technique at zero cost (fully flexible technologies). We...

A free entry model with linear costs is considered where firms first choose their entry time and then compete in the market according to the resulting timing decisions. Multiple equilibria arise allowing for infinitely many industry output configurations encompassing one limit-output dominant...

We demonstrate that a downstream firm (an incumbent) may source to an upstream firm (a potential entrant) for the sole purpose of entry deterrence. The reason is that, on the one hand, as a supplier, the potential entrant would have a second mover's disadvantage upon its entry into the...

This study analyzes the optimal provision of goods in a market characterized by vertical product differentiation. We consider a duopoly model in which incumbents may introduce a new product with certain quality, and decide whether to keep or to withdraw the existing product from the market. We...

The article examines a differentiated-products duopoly model where the firms make entry decisions to two markets and then choose prices. The effects of product differentiation and entry costs are analyzed in two games: with and without price discrimination between the markets. Allowing price...

We document entry and capacity expansion in US long-distance fiber-optic networks before and during the "telecom boom." We disentangle the many swaps and leases between networks in order to measure owned route miles versus route miles shared with other carriers. Entry appears much more moderate...

The number of producers in the U.S. tire industry grew for 25 years and then declined sharply, and the industry evolved to be an oligopoly. The role of technological change in shaping the industry's market structure is explored. A model of industry evolution featuring technological change is...

We examine the effects of entry on the pricing behavior of incumbent legacy airlines in a market where the newcomer is a rapidly expanding low-cost carrier - the Brazilian airline industry in the early 2000s. We estimate the timing and the determinants of price responses to entry allowing them...
