We incorporate a renewable resource as a factor of production and store of value into an overlapping generations model. We characterize dynamics and stability of steady state equilibria by introducing the concave resource growth function. The nature of equilibria in the presence of...

The purpose of this paper is to analyze an optimal one-period labor contract between one firm and one worker when there is no precommitment on employment. I assume, instead, that implementation is the responsibility of a third party (e.g. court of law) that observes only the wage rate and the...

We investigate the effect of government policies on fertility in a model where children are mainly seen as investment goods. To illustrate this effect we construct a simple overlapping generations economy in which households (parents) can invest both in children and financial assets. An...

We ask the question: Why is it proposed that successful structural economic reforms (such as deregulation) require accompanying fiscal policy actions? And under what conditions can gradual reforms succeed? We use a dynamic general equilibrium model. We show that financial repression increases...

In this paper we let economic agents choose whether to become fully rational or stay boundedly rational. Boundedly rational agents are less sophisticated in their information processing abilities. It is costly to acquire information needed to become fully rational, and thus not all agents are...

We study the effects of labour market imperfections and the capital stock on equilibrium unemployment. With an exogenous capital-labour ratio, stronger labour market imperfections promote equilibrium unemployment. However, the relationship between the long-run unemployment and the capital stock...

We address the question of whether competition makes loan markets more fragile in the sense of increasing the equilibrium bankruptcy risk of firms. This is done using a model of the interaction between the concentration of the banking sector and the investment strategies of imperfectly...

The main proposals for the reform of payroll-based employers' social security contributions have been the (partial) replacement of the contribution by increased sales tax and the so called SII-contribution, in which the base would consist of the wage bill and the operating margin of the firm. In...

This paper deals with some aspects of the Finnish economic crisis in the 1990s by starting with a quick description of the main macroeconomic features of the crisis together with some empirical evidence on price and wage as well as interest rate determination. With these as a background a...
