Clements (2004) makes the following two claims: (i) unlike direct network effects, increases in the size of the market do not, in the case of indirect network effects, make standardization more likely, but (ii) indirect network effects are associated with excessive standardization. We show in...

In this paper we analyse the role of asymmetric information between firms and consumers about market conditions. In standard models of oligopoly informational advantages of firms over customers do not play a role because all prices are observable. When customers are unable to observe all...

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...

R&D is an inherently dynamic process which involves different intermediate steps that need to be developed before the completion of the final invention. Firms are not necessarily symmetric in their R&D abilities; some may have advantages in early stages of the R&D process while others may have...

In traditional Keynesian and neoclassical models, the transmission of product demand changes to the labour market generally involves wage-price sluggishness or counter-cyclical real wage movements. In practice, however, real wages are often acyclical or procyclical, and wages and prices are...

This paper is a reflective survey of past and recent econometric work on the growth of firms. Most of this work suggests that firm size follows a random walk; i.e. that corporate growth rates are random. The survey documents this, and shows what a strong result this is by contrasting it with...

The deregulation of the telecommunications industry has resulted in a variety of industry structures which have been created in the hope of increasing competition. One example is the licensing of cellular telephone services in the United States. In the face of scarce radio spectrum, the Federal...

This paper studies the impact that capital market imperfections have on the natural selection of the most efficient firms by estimating the effect of the pre-deregulation level of leverage on the survival of trucking firms after the Carter deregulation. Highly leveraged carriers are less likely...

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...

In this paper we specify and estimate a structural model of competition for the European airline industry to assess the potential for price reductions if competition increases. The model has two distinguishing features: First, we allow for firms to make short- and long-run decisions by...
