This review considers the role of environmental effects in transport investment appraisal, mainly from the perspective of cost-benefit analysis, the most widely adopted appraisal technique. Although the basic principles of CBA are straightforward, several complications are identified that may...

This paper studies urban sustainability from the perspective of externalities. We develop a general spatial equilibrium model of a monocentric city, in which two types of externalities occur. On the one hand, pollution in the industrial centre leads to a spatially differentiated deterioration of...

One of the policy options to increase the efficiency in the provision of scarce water resources is a reduction in transaction costs in water chains by developing integrated forms of water management. Integrated water management in case of river basin areas may comprise inter alia: (1) increasing...

The widespread use of pesticides in agriculture provides a particularly complex pattern of multidimensional negative side-effects, ranging from food safety related effects to the deterioratian of farmland ecosystems. The assessment of the economic implications of such negative processes is...

This paper aims to provide a statistical analysis of the relative economic performance of Italian tourist areas. It uses two modelling approaches to estimate the competitiveness of these regions, viz. data envelopment analysis (DEA) and the Malmquist method. Our results show that the...

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...

Information and Communication Technologies (ICT) have become important tools to promote a variety of public goals and policies. In the past years much attention has been given to the expected social benefits from deploying ICT in different fields (transportation, education, public participation...

Many networks such as the Internet have been found to possess scale-free and small-world network properties reflected by so-called power law distributions. Scale-free properties evolve in large complex networks through self-organizing processes and more specifically, preferential attachment. New...

This paper offers both a conceptual and an operational model that aims to map out the causes and implications of ICT perceptions and views of urban policy makers and/or administrative officials (denoted as urban front liners). This is followed by the presentation of an opera- tional path model,...

A consistent mapping of all complex ramifications (including direct and indirect effects) of various greenhouse policies in an open institutional economy requires the use of a general equilibrium framework. From the existing set of available equilibrium models we have selected the so-called...
