Frequently, aspiring entrants have only limited information about their potential rivals’ entry decisions. As a result, the outcome of the entry game may be that more firms enter than the market can sustain; or, at least, that unnecessary entry investments are made. We refer to these outcomes...

This paper uses a case study approach to explore the effects of NAFTA and GATT membership on innovation and trade in the Mexican soaps, detergents and surfactants (SDS) industry. Several basic findings emerge. First, the most fundamental effect of NAFTA and the GATT on the SDS industry was to...

When will a monopolist have incentives to foreclose a complementary market by degrading compatibility/interoperability of his products with those of rivals? We develop a framework where leveraging extracts more rents from the monopoly market by 'restoring' second degree price discrimination. In...

The purpose of this paper is to try to shed some new light on the current industrial policy crisis. This paper proposes that the industrial policy debate is shaped by knowledge about the functioning of the underlying industrial structure, which in turn is the Gegenstand of scholars in the field...

I revisit the relation between aftermarket power and basic market competition. I consider an infinite period model with overlapping consumers: in each period, one consumer is born and joins one of the existing installed bases, then aftermarket payoffs are received by sellers and consumers, then...

We study the repeal of a regulation that imposed maximum wholesale and retail markups for all but five fresh fruits and vegetables. We compare the prices of products affected by regulation before and after the policy change and use the unregulated products as a control group. We find that...

We estimate, using event study techniques, the impact of the main events in an antitrust investigation on a firm’s stock market value. A surprise inspection at the firm’s premises has a strong and statistically significant effect on the firm’s share price, with its cumulative average...

This paper empirically investigates the effectiveness of competition policy by estimating its impact on Total Factor Productivity (TFP) growth for 22 industries in 12 OECD countries over the period 1995-2005. We find a robust positive and significant effect of competition policy as measured by...

The paper discusses economic theories of harm for anti-competitive margin squeeze by unregulated and regulated vertically integrated firms. We review both predation and foreclosure theories, as well as the mere exploitation of upstream market power. We show that foreclosure provides an...

The uniform pricing puzzle for vertically differentiated products states that a monopolist sells high and low quality products at the same price despite the fact that quality is perfectly observable and that there are no significant costs of adjusting prices. The puzzle is relevant for movies,...
