This paper explores the inerrelations between pricing, capacity choice and financing in transportation networks. It builds on the famous Mohring-Harwitz result on self-financing of optimally designed roads under optimal congestion pricing, and specifically asks the following questions: (1) to...

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 deals with some of the features of static models of road traffic congestion that have caused much debate in the literature. It first focuses on the difficulties arising with the backward-bending cost curve defined over traffic flows in the context of `continuous congestion'. The...

This paper addresses the issue of spatial environmental externalities from a spatial general equilibrium perspective. We present a general equilibrium model of an island economy, with one city and a rural hinterland. Apart from market-internal interactions such as those governing trade and...

This paper develops a continuous time - continuous place model of road traffic congestion, based on car-following theory. The model fully integrates two archetype representations of traffic congestion technology, namely "flow congestion", originating in the works of Pigou, and "vertical queuing"...

Large-scale investments in transport infrastructure have been traditionally evaluated assuming the equivalence between direct and indirect economic effects (Jara-Diaz,1986), which is only correct under -generally non-guaranteed- perfect competition assumptions. Despite this common practice there...

This paper considers second-best congestion pricing in the monocentric city, with endogenous residential density and endogenous labour supply. A spatial general equilibrium model is developed that allows consideration of the three-way interactions between urban density, traffic congestion and...

Congestion on highways often occurs by sudden transitions from free flow traffic to synchronized traffic. Associated with such phase transitions are large decreases in speed. Such phase transitions seem to be often caused by temporal distortions in traffic flows, such as a short peak in the flow...
