This article, published in 1991, describes the two great ideologies of the market and the state that shaped antitrust law at its inception. In the evolutionary vision, market outcomes are spontaneous and unintended results of countless interactions of self-interested individuals; the resulting...

Antitrust enforcement regimes rely on two types of penalties for deterrence: penalties against the violating firm and penalties against the agents of the violating firm. In this paper I examine the economics of punishing agents versus firms. My area of application is antitrust, but the argument...

We analyze how leniency affects cartel pricing in an infinitely-repeated oligopoly model where the fine rates are linked to illegal gains and detection probabilities depend on the degree of collusion. A novel aspect of this study is that we focus on the worst possible outcome. We investigate the...

This paper deals with the optimal enforcement of competition law between merger and anti-cartel policies. We examine the interaction between these two branches of antitrust, given the budget constraint of the public agency, and taking into account the ensuing incentives for firms in terms of...

Henry G. Manne, our friend, Mentor, and colleague, was a pioneer in the economic analysis of law. By consistently challenging the notion that existing institutions were well understood, he expanded the domain of economics to new and fertile ground. In that spirit, our goal in this article is to...

This paper analyses how the endogenous detection of an upstream cartel by a down-stream buyer allows the detecting firm to raise rivals' cost. We model a market with a vertical structure, where a stable all-inclusive cartel is operating in the upstream market which provides an input to a...

The focus of cartel damages law is on the recovery of the cartel overcharge. Parties other than purchasers are often neglected, not only as a matter of judicial practice, but also due to legal restrictions. We argue that a narrow concept of standing—which excludes parties that supply either...

A bundled discount occurs when a seller charges less for a bundle of goods than for its components when sold separately. A characteristic of such discounting is that a rival who makes only one of the products in the bundle may have to give a larger per item discount in order to compensate the...

Antitrust Law can be described as the set of legal rules that regulate the current or potential power of the companies on a certain market, on behalf of public interest. In practice, the Antitrust Law prohibits the execution of restrictive competition practices, the acquisition of a dominant...
