In this paper, a dynamic model of road traffic congestion is presented, with an elastic overall demand for morning peak road usage, and with the congestion technology used being 'flow congestion'. It is demonstrated that in such a case, the optimal time-varying toll should include a 'flat',...

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...

This paper studies some of the properties and fundamentals of static models of road traffic congestion that have triggered much debate in the literature. The first part of the paper focuses in particular on the difficulties arising with the backward-bending cost curve in the context of...

This paper analyses the adoption of energy-efficiency enhancing technologies by heterogeneous firms. The fact that energy use does not only cause external environmental costs through pollution, but also directly affects the profitability of the firm and hence its behaviour on input and output...

Conventional economic wisdom suggests that congestion pricing would be an appropriate response to cope with the growing congestion levels currently experienced at many airports. Several characteristics of aviation markets, however, may make naive congestion prices equal to the value of marginal...

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

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

This paper proposes an alternative, dynamic framework for estimatingtime-varying values of travel time savings and values of schedule delay, in whichtime-preferences are represented as the time-varying excess willingness to pay(EWPT) to being in the one location, over being elsewhere. It is...

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...

In this article we study patterns of vertical product differentiation in a multi-product monopoly using a random utility model. Prior research shows that applying such a model in a multi-product setting implies symmetric patterns of product differentiation in which all product variants of a...
