Various plants and resources such as orchards are vulnerable to the detrimental effects of successful invasions by alien animal or plant species. To outline an appropriate policy response, we first use renewal theory to construct a stochastic model of optimal orchard management in the presence...

This paper studies urban sustainability from the perspective ofexternalities. We develop a general spatialequilibrium model of a monocentric city, in which two types ofexternalities occur. On the one hand, pollution inthe industrial centre leads to a spatially differentiateddeterioration of the...

This paper gives a concise overview of environmental-economicanalysis. Important issues and modern developments in the field aresurveyed in a systematic way. Next, the concept of sustainabledevelopment is discussed, as it has dominated environmental economicsfor almost a decade now. In addition,...

There is an increasing awareness of the potential of nonlinear modeling in regional science, which can partly be explained by the recognition of the limitations of conventional equilibrium models in complex situationsand partly by the easy availability and accessibility of sophisticated...

The effect of economic behaviour of different actors on the size of a market area is a classical subject of study in regional economics and over the years many studies have been published on this subject. Regional market differences are not only relevant in (location-) allocation theory, but...

After the Kyoto agreements the need has arisen to trace the implications ofvarious international environmentalstrategies. In this paper, we discuss relevant modelling issues ofincorporating important environmental policy measures in one ofthe popular applied general equilibrium models for...

There is an increasing demand for transport decisions to be made in thelight of some form of what may generically be called cost benefit analysis(CBA). The actual techniques may vary and often deviate quite significantlyfrom the conventional economic concept of CBA but in all cases theprocedures...

This paper presents a framework for analysing spatial aspects of environmental policies in the regulation of trans-boundary externalities. A spatial price equilibrium model for two regions is constructed, where interactions between these regions can occur via trade and transport, via mutual...
