This Article studies the durapolist, the durable-goods monopolist. Durapolists have long argued that, unlike perishable-goods monopolists, they face difficulties in exercising market power despite their monopolistic position. During the past thirty years, economists have extensively studied the...

We posit and empirically test the hypothesis that airlines are able to charge a fare premium in markets that originate in their domestic country relative to similar markets that originate in foreign countries. To this end, we focus on intercontinental one-stop air travel trips for which the...

A known policy dilemma occurs between the need to curb extra-large profits by some industries, like pharmaceuticals, and the need to ensure the incentive to produce is not damaged. This paper shows that a profit cap, imposed via taxation on a group of firms, can simultaneously eliminate...

This paper examines whether there is a natural barrier to entry in the credit rating industry. We consider an in nite horizon model in which each period, an original incumbent faces competition from an entrant randomly selected from a pool of ex ante identical potential entrants. The incumbent's...

We present an infinite horizon model that studies the competition between a relatively ineffective incumbent Credit Rating Agency (CRA) and a sequence of entrant CRAs that are potentially more effective but whose ability in appraising default risk is unproven at the time they enter the market....

We consider an empirical model of worldwide airline alliances that we apply to a large set of companies for the period 19952000. Using observations at the network level, we estimate a cost, capacity, and demand system that accounts for cross-price elasticities. Our contribution consists in...

This paper presents an updated narrative of the history of the global lysine cartel and the legal consequences for its members in the United States. The story focuses especially upon the role of economists in calculating the size of overcharges and how the estimates can affect the decisions of...
