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...

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,...

In situations where the traditional instruments of trade policy are not available, protection for importcompeting industries can be given only indirectly. One of the candidates of giving indirect subsidies is environmental regulation. The competitiveness of a domestic industry can be improved by...

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...

This paper surveys the literature on the relationship between international trade in goods and the factors and the environment. Traditional approaches based on the Heckscher-Ohlin trade model and more recent models looking at non-competetive market structures are discussed. Moreover, the paper...

Social norms and intrinsic motivations lead to voluntary environmentally responsible behaviour even in the absence of environmental policy. The paper shows that the introduction of environmental policy may lead to a reduction of voluntary abatement and sometimes may increase emissions and...
