The purpose on this paper is twofold. First, we present an alternative model of agglomeration and trade that displays the main features of the recent economic geography literature while allowing for the derivation of analytical results by means of simple algebra. Second, we show how this...

Backward vertical integration by a dominant firm into an upstream competitive industry causes both input and output prices to rise. The dominant firm's cost advantage may or may not offset the negative effect to higher prices on social welfare. Whether it does depends on a simple indicator...

We consider a homogenous good oligopoly with identical consumers who learn about prices either by (sequentially) visiting firms or by consulting a price agency who sells information about which firm charges the lowest price.

Built on the location model, this paper studies the rivalry of two firms in an industry through two-part tariffs. It is found that kinky profit functions are responsible for the coincidence of imperfectly competitive equilibrium and cartelization outcome. A duopoly likely results in higher entry...

We analyze two-part tariffs in oligopoly, where each firm commits to a certain quantity. The model is an extension of the one introduced in Harrison and Kline (2001).We show that their main results are reversed when the model is extended from one to two types of consumers.

The main objective of this paper is to analyze the links between product market competition, innovation and growth. We capture the idea that firms innovate in order to try to escape - albeit temporarily - from the pressure of competition exerted on them by their rivals. At each date, an industry...

In our study of four industries, we confirmed that there is a relationship between the stage through which the industry is going, thus its level of turbulence, and the nature of cooperative strategies. More specifically it appears in situations of industry reconfiguration, that the smaller, more...

This paper aims at measuring the impact of competition on productivity growth of the Tunisian manufacturing sector at the firm level. To investi-gate the impact of competition on productivity we use two procedures. The first one is a two-step procedure; the second one is a one step procedure. We...
