We present estimates of 4 and 8 firm concentration ratios by industry and in weighted aggregate form for the manufacturing sector for Chinese enterprises for 2002 and 2007. These are then compared to available estimates for the same years and industrial classification for the US. These...

This survey examines recent developments in economic research relating to antitrust, paying specific attention to research in the areas of collusion and merger enforcement. Research relating to both collusion and mergers has made significant advances in the last twenty years. With respect to...

In this paper, we provide a conceptual framework for understanding the phenomenon of exclusive dealing, and we explore the motivations for and effects of its use. For a broad class of models, we characterize the outcome of a contracting game in which manufacturers may employ exclusive dealing...

In response to the "standardless" approach used in LePage's v. 3M, the Antitrust Modernization Commission (AMC) and others advocate using a discount allocation approach to assess whether bundled loyalty discounts violate Section 2 of the Sherman Act. This approach treats loyalty discounts like...

Recent empirical evidence indicates that capital structure changes affect pricing strategies. In most cases, prices increase following the implementation of a leveraged buyout of a major firm in an industry, with the more levered firm charging higher prices on average. Notable exceptions exist...

We consider vertical contracts where the retail market may involve search frictions. Minimum advertised price restrictions (MAP) act as a restraint on customers' information and so can increase search frictions in the retail sector. Such restraints, thereby, soften retail competition--an impact...

Merger policy is the most active area of U.S. antitrust policy. It is now widely believed that merger policy must move beyond its traditional focus on static efficiency to account for innovation and address dynamic efficiency. Innovation can fundamentally affect merger analysis in two ways....

This paper examines the rationale for vertical restraints. It shows that there are important circumstances under which these restrictions have significant anti-competitive effects. The paper focuses on the consequences of exclusive territorial arrangements among the retailers of two products...

Entry represents a fundamental threat to cartels engaged in price fixing. We study the extent and effect of this behavior in the largest price fixing case in US history, which involves generic drugmakers. To do so, we link information on the cartel's internal operations to regulatory filings and...

A supergame theoretic price-setting model of collusion is calibrated to data from the North American passenger car market before, during, and after the voluntary restraint arrangements (VRAs) with Japan. Conclusions about whether the model is consistent with the bans from the various regimes...
