The aim of this paper is to analyze and depict urban equilibrium from the perspective of a complex force field between (positive) agglomeration economies and (negative) environmental externalities. Based on a simplified representation of a linear urban economy, a general-equilibrium model is...

The article contains a welfare economic analysis of road transport's external effects. First, we discuss the definition of external effects. Applying this definition, it is concluded that road transport activities give rise to a wide range of external costs. However, there are no external...

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...

This paper aims to analyze and depict urban equilibrium from the perspective of a complex force field between (positive) agglomeration economies and (negative) environmental externalities. Based on a simplified representation of a linear urban economy, an archetypical model based on general...

In this paper, we investigate congestion caused by differences in desired or possible speeds. Especially outside peak hours, speed differences are probably one of the most important reasons for congestion. Although the model setting, with one lane and no overtaking, may seem simple at first...

Private toll roads are now seriously considered as an alternative to public (free-access) road infrastructure. Nevertheless, complete private provision without governmental control is only rarely considered. A main consideration against private roads would be that operators would be primarily...

Environmental sustainability issues have in recent years received much attention from the side of environmental scientists and economists. There is a broad recognition on the relevance of external effects in open and interacting spatial systems. It would be helpful if ecological economic...

In urbanised areas around the world, road pricing policies are considered more and more frequently, the aim often being to alleviate (some of the) external traffic-related costs. To assess the effects of a proposed road pricing measure, several evaluation measures can be used, coming from...
