This paper sheds light on a recent empirical controversy about the effect of competition on price discrimination in airline markets (Borenstein and Rose (1994), Gerardi and Shapiro, (2009)). We introduce individual demand uncertainty into Hotelling’s model of horizontal product differentiation...

We develop and empirically test a labor market model with Public Employment Agencies (PEA) in order to understand why not all vacancies use the costless services provided by the PEA. We show that both the search market and the PEA can be active in equilibrium. In such an equilibrium, workers...

An advantage of collective wage agreement is that search and business-stealing externalities can be internalized. A disadvantage is that it takes more time before an optimal allocation is reached because more productive firms (for a particular worker type) can no longer signal this by posting...

A dynamic 'car-following' extension of the conventional economic model of traffic congestion is presented, which predicts the average cost function for trips in stationary states to be significantly different from the conventional average cost function derived from the speed-flow function. When...

The application of aggregate indicators in environmental-economic research has received littleattention so far. An important reason is the incompleteness of environmental data. This articlepresents a systematic approach to construct indicators of environment and economy on a macrolevel. It...
