We consider an oligopolistic market where firms compete in price and quality and where consumers are heterogeneous in knowledge: some consumers know both the prices and quality of the products offered, some know only the prices and some know neither. We show that two types of signalling...

In this paper a model, based on the nested multinomial logit model, is used to analyze airport competition and airline competition in a multiple airport region. It is shown that if the frequency elasticity of demand is smaller than 1, airfare-frequency and airport tax equilibria exist and are...

In its landmark ruling in Illinois Brick Co. v. Illinois in 1977, the U.S. Supreme Court restricted standing to sue for recovery of antitrust damages to direct purchasers. However, antitrust damages are typically (in part) passed on to intermediaries lower in the chain of production and...

This paper analyzes the relative economic power position of home carriers in hub-and-spoke systems. Hub-and-spoke systems may lower costs on densely traveled routes and enable economically viable operations on less densely traveled routes. The reverse side is probably that carriers enjoy...

Commercial firms are increasingly tying the sales of their products with donations to a charitable cause. Apart from a charitable motive, offering these charity-linked bundles could be a strategic instrument for firms to increase profits. We report the results of an experiment that investigates...

This paper develops a model in which market structure is determined endogenously by the choice of intermediation mode. We consider two representative business modes of intermediation that are widely used in real-life markets: one is a middleman mode by which an intermediary holds inventories...

We extend the models in ("Competition in two-sided markets" of Armstrong (2006, Rand Journal of Economics) by adding within-group externalities. In the monopoly and duopoly cases, positive within-group externalities reduce the price of the own group. Negative externalities have an opposite price...

This paper shows that Hausman-McFadden and related tests for the multinomial logit model are not informative about failure of IIA, but only about specification error in the deterministic part of the utilities attached to choice alternatives. It is shown that the multinomial logit cannot be...

In the last decade, many European countries have seen a sharp increase in the number of automated fueling stations. We study the effect of this process innovation on prices at stations that are automated and their competitors using a difference-in-differences matching strategy. Our estimates...
