We formulate a simple static equilibrium model for the electricity market taking account of both Green certificated and CO2-emission permits. The objective is to investigate the relationship between these markets under the existence of upper and lower price-bounds on the Green certificates, both...

In this paper, we study the effects of introducing endogenous costs in a Tullock model of rent-seeking. We show that unions can be efficiency improving, and that the firms' level of effort depends more critically upon the number of firms participating in the contests when unions are present. We...

The main objects below are transferable-utility games in which each agent faces an optimization problem, briefly called production planning, constrained by his resource endowment. Coalitions can pool members's resources. Such production games are here extended to accomodate uncertainty about...

The organisation of the paper is as follows. Section II provides a short review of the job search and job-match theory, together with a discussion of previous empirical findings. In Section III, we give a brief description of some institutional features of the Norwegian educational system and...

In non-cooperative models of the family, improved productivity in contribution to a family good typically implies that, in equilibrium, one contributes more to the public good, while one's spouse contributes less. Thus, improves contribution productivity has a negative strategic effect on one's...

In non-cooperative family models, being good at contributing to family public good like household production may reduce one's utility, since it tends to crowd out contributions from one's spouse. Similar effects also arise in cooperative models with non-cooperative threat point: improved...

A multinational enterprise is subject to taxation by two jurisdictions who compete to capture its rents, while being aware that the firm also has investment options outside these jurisdictions. The firm has private informatio about its efficiency. We show that a higher outside option for the...

In this paper, we attempt to develop an intertemporal model of rural-to-urban migration in the context of a poor rural economy. With a peasant household as the decision making unit we explore how rural-to-urban migration may be adopted as a strategy mto cope with the income risks arising from...

In most member states of the European Union (EU), issues concerning sound and sustainable finances are high on the political agenda. This paper briefly reports the findings of 12 country studies that investigate the impact of the demographic transition on the intergenerational stance of current...

Employment of apprentices seems to follow the business cycle. An interesting question is whether this is based on an investment policy where firms recruit when the labour market indicates skill shortage. Alternatively it may be that the firms are myopic and basically hire apprentices in booming...
