We analyze two and three-dimensional variants of Hotelling's model of differentiated products. In our setup, consumers can place different importance on each product attribute; this is measured by a weight in the disutility of distance in each dimension. Two firms play a two-stage game; they...

A number of products that display positive network effects are used in variable quantities by heterogeneous customers. Examples include corporate operating systems, infrastructure software, web services and networking equipment. In many of these contexts, the magnitude of network effects are...

This paper develops a model of airline competition. The model is based on a demand and pricing equation system, which is estimated for the Spanish airline market. The empirical implementation of the equation system relies on a simultaneous rather than a consecutive procedure. I test the...

This paper develops a foreign expansion index (FEI) of the firm which integrates various dimensions of commitment to internationalization, i.e. exports, foreign penetration operations and FDI. This study focuses on Italy, constructing FEIs for each of some 4,000 firms for three periods...

This paper investigates the effect of capacity constraints on the sustainability of collusion in markets subject to cyclical demand fluctuations. In the absence of capacity constraints (i.e. a limiting case of our model), Haltiwanger and Harrington (1991) show that firms find it more difficult...

Bidders have to decide whether and when to incur the cost of estimating their own values in auctions. This can explain why people seem to get carried away, bidding higher than they had planned before the auction and then finding they had paid more than the object was worth to them. Even when...

The article examines the optimal choice of monitoring intensity when workers face external incentives (incentives that are not provided by the firm), such as tips, satisfaction from working well, or the desire to build reputation in order to be more attractive to other employers. Increase in...

The point of departure in this paper is the diagnosis of Hoehn and Szymanski (1999) that the interlocking system of European football creates an unbalanced system. To secure competitive balance at both the European and the national level, they recommend to reform European football into a closed...

It is usual to estimate willingness-to-pay in discrete choice models through Logit models –or their expanded versions-. Nevertheless, these models have very restrictive distributional assumptions. This paper is intended to examine the above mentioned issue and to propose an alternative...

Comparative advertising by one brand against another showcases its merits versus the demerits of the other. In a two-stage game among finitely many firms, firms decide first how much to advertise against whom. In the second stage, given the advertising configuration, firms compete as Cournot...
