This is a survey of the economic principles that underlie antitrust law and how those principles relate to competition policy. We address four core subject areas: market power, collusion, mergers between competitors, and monopolization. In each area, we select the most relevant portions of...

This paper presents a Cournot oligopoly model with R&D spillovers both within and across industries. The aim is to provide an appropri- ate theoretical foundation for three different hypotheses regarding the impact of the local production structure on innovation and output, as well as addressing...

Our article investigates the impact of vertical integration (without foreclosure) on innovation. We compare cases where either (i) two manufacturers or (ii) a manufacturer and a vertically integrated retailer invest. Then, the independent manufacturer(s) and the retailer bargain over non-linear...

This paper considers a general symmetric quantity-setting oligopoly where the "coefficient of cooperation" defined by Cyert and DeGroot (An Analysis of Cooperation and Learning in a Duopoly Context, 1973) is interpreted as the parameter indicating severity of competition. It is obtained that...

This study compares energy and emission taxes used to control pollution and provide incentives for the adoption of an advanced abatement technology in a Cournot oligopoly. We examine multistage games where the government may intervene in order to maximize social welfare by setting an...

This article explores the possibility of associating firm size vis-à-vis industry size with firm-level R&D led-innovation and the resultant impact(s) on industry level output and price. We consider an oligopolistic industry having one dominant firm and some fringes. Innovation by the dominant...

We examine optimal industrial and trade policies in a series of dynamic oligopoly games in which a home and a foreign firm compete in R & D and output. Alternative assumptions about the timing of moves and the ability of agents to commit intertemporally are considered. We show that the home...

Allowing firms to cooperate in their R&D is an industrial policy, which has received much attention in recent economics literature. Many of these contributions are based on the seminal analysis of d'Aspremont and Jacquemin (1988). We provide a general version of their model, which encompasses...

Firms raise cost-reducing alliances before competing with each other, but cannot fully internalize the shared knowledge. When spillovers are local and transit through the network of alliances, stable architectures with a moderate level of asymmetry are identified.
