Recent empirical work has shown that there exists a negative relation between wages and unemployment estimated across regions. Our model recognises the spatial dimension of the so-called wage curve by using a Hotelling/Salop framework in which a finite number of firms compete for heterogeneous...

In this paper, we analyze how to utilize discount rates in intergenerational projects. Firstly, neoclassical decision-making is depicted in Ramsey and overlapping-generations models (OLG-models). Afterwards we investigate the utilization of time preference rates and opportunity cost rates in an...

This paper analyses the choice of an inter-generational discount rate as well as a method for inter-generational discounting. It is shown that the pure time preference rate is irrelevant for inter-generational comparisons. However, the application of the growth time preference rate - with...

Ecological damages have to be evaluated in monetary terms for implementation in an economic analysis. Economic theory is based upon individual preferences (methodological individualism): Ecological damages can only be socially evaluated when individual values are available. However, in sharp...

This paper investigates the sustainability of the German economy when reaching the Kyoto emissions reduction target. We use a special intergenerational discounting technique which actually takes into account intergenerational peculiarities in an overlapping generations modeling framework which...

We investigate the simultaneous impact of output and input market imperfections on the characteristics and size of regional economic activity. Firms, producing imperfect Substitutes, face product specific demand shocks which translate into firm-specific shocks. The more different the products...

We investigate the consequences of redistribution policy on migration and trade in a Standard two-good Heckscher-Ohlin framework. With free trade and factor price equalization, abolishing migration barriers is redundant. With the introduction of government activity, matters change drastically....

We develop a growth model with endogenous technological progress in which the financial sector plays an explicit role. Thereby we discuss the role of different financial regimes in the growth process. We contrast a bank-dominated financial system with a market-dominated system. In the first one...

We analyze the possibility and consequences of coalition-formation amongst suppliers of retail services. We first provide a framework in which producers of Substitutes have an incentive to Cluster in market places in order to attract consumers dispersed in space. Owing to spatial externalities,...
