A principal uses security bid auctions to award an incentive contract to one among several agents in the presence of hidden action and hidden information. Securities range from cash to equity and call options. “Steeper” securities are better surplus extractors that narrow the gap between the...

If bidders are uncertain whether the auctioneer sticks to the announced reserve, some bidders respond by strategic non-participation, speculating that the auctioneer may revoke the reserve. However, the reserve inadvertently signals the auctioneer’s type, which drives a unique separating and a...

In a spatial competition setting there is usually a non-negative relationship between competition and quality. In this paper we offer a novel mechanism whereby competition leads to lower quality. This mechanism relies on two key assumptions, namely that the providers are motivated and...

Competing firms often have the possibility to jointly determine the magnitude of consumers’ switching costs. Examples include compatibility decisions and the option of introducing number portability in telecom and banking. We put forward a model where firms jointly decide to reduce switching...

Building on a model of the interaction of risk-averse firms that compete in forward and spot markets, we develop an empirical strategy to test whether oligopolistic firms use forward contracts for strategic motives, for risk-hedging, or for both. An increase in the number of players weakens the...

Using longitudinal data on individuals from the European Community Household Panel for thirteen countries during 1995-2001, I investigate the wage premium for permanent jobs relative to temporary jobs. For men, the wage premium for a permanent job is lower for older workers and native born...

We empirically test the relationship between hiring discrimination and labour market tightness at the level of the occupation. To this end, we conduct a correspondence test in the youth labour market. In line with theoretical expectations, we find that, compared to natives, candidates with a...

This paper analyses a model in which firms cannot pay discriminate based on year of entry to a firm, and develops an equilibrium model of wage dynamics and unemployment. The model is developed under the assumption of worker mobility, so that workers can costlessly quit jobs at any time. Firms on...

The objective of this paper is to construct and quantitatively assess an equilibrium search model with on-the-job search and general human capital accumulation. In the model workers enter the labour market with different abilities and firms differ in their productivities. Wages are dispersed...

We determine workforce composition and wages in firms in the presence of productivity spill-overs between co-workers. In equilibrium, workers’ wages depend on the production structure of firms, own group size, and aggregate workforce composition in the firm. We estimate the wage effects of...
