The paper analyses the impact of tax competition on innovation in the public sector. It is shown that the effects of increased mobility of the tax base on innovation and growth are ambiguous. The negative relationship is more likely, however. Moreover, it is shown that a Leviathan government may...

The paper uses a continuous-time overlapping-generations model with endogenous growth and pollution accumulation over time to study the link between longevity and global warming. It is seen that increasing longevity accelerates climate change in a business-as-usual scenario without climate...

We develop a model where firms profit from coercing workers into employment under conditions violating national law and international conventions and where bureaucrats benefit from accepting bribes from detected perpetrators. Firms and bureaucrats are hetero-geneous. Employers differ in their...

This paper looks at a model in which two countries trade agricultural and manufactured commodities. The manufactured-goods sector produces with increasing returns to scale under conditions of monopolistic competition. It is shown that an increase in land endowment (or an increase in agricultural...

The paper investigates the spatial patterns of industrial location and environmental pollution in a new-economic-geography model. Factors of production and their owners are mobile, but factor owners are not required to live in the region in which their factors are employed. Under laisser-faire,...

Is tax competition good for economic growth? The paper addresses this question by means of a simple model of endogenous growth. There are many small jurisdictions in a large federation and individual governments benevolently maximise the welfare of immobile residents. Investment is costly:...

The paper combines an economic-geography model of agglomeration and periphery with a model of species diversity and looks at optimal policies of biodiversity conservation. The subject of the paper is 'natural' biodiversity, which is inevitably impaired by anthropogenic impact. Thus, the economic...

The paper looks at a model of directed technical change in an environmental-economics context. Firms can do conventional or 'green' R&D or they can abate emissions at the end of pipe. The paper has two main foci. On the one hand, it investigates the impact of environmental regulation on the...

Commodities do not only serve the purpose of satisfying direct needs in the production and con-sumption process. Some of them can also be used to display social status and to affect the position of an individual in society. This paper addresses the question under which circum-stances...

The paper surveys economic aspects of sustainability and the use of complex ecological systems. In a first step, an economist's view of the concept of sustainability is presented. Then, a simple model of the economic use of a dynamic ecological system is discussed. It is shown how economically...
