This paper shows the strategic aspects of international outsourcing in an oligopolistic market, if outsourcing is attractive because of fixed cost savings. We show that outsourcing decisions are strategic substitutes. Furthermore, we demonstrate that due to decreasing individual output,...

Due to different costs of integrated production and outsourcing, the choice of a firm influences the strategy of the competitor via the output price. Therefore, the resulting market constellation depends...

The paper analyzes the sustainability of governmental debt and its welfare properties in an overlapping generations economy with stochastic production and capital accumulation. In the absence of taxation, equilibria with positive debt generically converge to debtless eauilibria are typically...

During the 1990s, temporary agency work has increased rapidly in most OECD countries. We augment the equilibrium unemployment model developed by Pissarides and Mortensen with temporary work agencies. Our model implies that technological improvements for placements and de-regulation of the sector...

Enrolment rates to higher education reveal quite large variation over time which cannot be explained by productivity shocks alone. We develop a human capital investment model in an overlapping generations framework that features endogenous fluctuations in the demand for education. Agents are...

I develop an agent-based computational economics (ACE) model with which I evaluate the aggregate impact of labor market policies. The findings are that governmentfinanced training measures increase the outflow rate from unemployment to employment. Although the overall effect is positive this...

To evaluate the effects of a universal program, i.e. all targeted get access, is associated with the problem that there are no individuals who represent the hypothetical or counterfactual state of being eligible to the program but not participating in it. In this study of a Swedish universal...
