We explore voluntary participation in pension arrangements. Individuals only participate when participation is more attractive than autarky. The bene􀏐it of participation is that risks can be shared with future generations. We apply our analysis to a pay-as-you-go system, a funded system...

A model is presented that explains the mix between funded and unfunded pension systems. It turns out that total pension and the relative shares of the two systems may be explained and are determined by the population growth rate, technological growth, the time-preference discount rate, the...

This paper studies markets plagued with asymmetric information on the quality of traded goods. In Akerlof's setting, sellers are better informed than buyers. In contrast, we examine cases where buyers are better informed than sellers. This creates an inverse adverse selection problem: The market...

We study an insurance model characterized by a continuum of risk types, private information and a competitive supply side. We use the model to investigate the welfare effects of discrimination (also known as risk selection). We postulate that a test is available that determines whether an...

In many countries, wind turbines are constructed as part of a strategy to reduce dependence on fossil fuels. In this paper, we measure the external effect of wind turbines on the transaction prices of nearby houses. A unique house price dataset covering the period 1985-2011 is used, including...

We derive and discuss a general, but simple geographical economics model with congestion, allowing us to explain the economic viability of small and large locations. The model generalizes some previous work and lends itself to analyzing the impact of public policy in terms of infrastructure...

This discussion paper resulted in a publication in 'Industry and Innovation', 2011, 18(3), 317-334.<P> This article presents a model of sequential decisions about investments in environmentally dirty and clean technologies, which extends the path-dependence framework of Arthur (1989). This allows...</p>

Popular urban tourist destinations are attracting large numbers of both overnight visitors and excursionists. Since urban cities perform a multitude of functions, the space requirements of tourists can, at times, interfere with those of local users. This paper addresses the issue of disutilities...
