This paper is concerned with the economics of urban externalities. We start by reviewing the literature on urban externalities, and observe that although many interesting contributions have been made, there seems to be sufficient scope and need for further research, both theoretically and...

Promoting investments in energy saving technologies is an important means for achieving environmental goals. Unfortunately, the empirical evidence on success conditions of policies is scarce. Based on a survey among Dutch firms, this paper sets out to identify the factors that determine the...

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

Ohta (2001) claims to have resolved a die-hard controversy on traffic congestion modeling by defining an inverse aggregate demand function that has traffic density as its argument-in Ohta's terminology the 'primitive term.'Using this demand function, Ohta shows that 'hypercongestion' may very...

We study interaction between the trips of two types of drivers on a two-lane road who differ by their desired speeds. The difference in desired speeds causes congestion, because slow drivers force fast drivers to reduce their speed. An interesting aspect of this type of congestion is that...

We explore the properties of various types of public and private pricing on a

A dynamic 'car-following' extension of the conventional economic model of traffic congestion is presented, which predicts the average cost function for trips in stationary states to be significantly different from the conventional average cost function derived from the speed-flow function. When...
