This discussion paper resulted in a publication in the <A href="http://www.sciencedirect.com/science/article/pii/S0014292108000810">European Economic Review</A>.<p>We study a two-sided market where a platform attracts firms selling differentiated products and buyers interested in those products. In the unique subgame perfect equilibrium of the game, the platform fully...</p></a>

Travelers often are incompletely informed about travel alternatives, which has important implications for various domains of travel behavior such as whether or not to make a trip, modal choice, the timing of a trip or route choice. During the last decade large efforts have been made to increase...

Despite a busy lifestyle – or perhaps as a result of a stressful lifestyle – more people than ever before make leisure trips, sometimes for a long time but in many cases just for short periods. Modern telecommunication technology brings attractive tourist destinations directly into the...

See the article in <I>Tourism Economics</I> (2013). Volume 19, Issue 5, pages 987-1004.<P> As a result of advances in ICT-services, transportation, and local development, among others, an increasing number of destinations is competing to attract both national and international visitors.

We study mergers in a market where N firms sell a homogeneous good and consumers search sequentially to discover prices. The main motivation for such an analysis is that mergers generally affect market prices and thereby, in a search environment, the search behavior of consumers. Endogenous...

This paper studies the incentives to merge in a Bertrand competition model where firms sell differentiatedproducts and consumers search for satisfactory deals. In the pre-merger symmetricequilibrium, the probability that a firm is the next one to be visited by a consumer is equal acrossfirms not...

By combining two large data sets (on international trade flows and cross-border mergers and acquisitions – M&As), we test two implications of Neary’s (2003, 2007) general oligopolistic equilibrium (GOLE) model (incorporating strategic interaction between firms in a general equilibrium...

This discussion paper led to an article in <I>Games and Economic Behavior</I> (2012), pp. 120-138.<P> 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,...</p></i>

Consider a government tendering a facility, such as an airport or utility, where one bidder owns a competing facility. With a "standard auction", this "existing operator" bids above the auctioned facility's expected profit, as winning means being a monopolist instead of a duopolist. This auction...

The search literature assumes that consumers know which firms sell products they are looking for, but are unaware of the particular variety and the prices at which each firm sells. In this paper, we consider the situation where consumers are uncertain whether a firm carries the product at all by...
