Price elasticities of transport demand are an important tool toassess the impacts of pricing policies. Empirical research on these elasticitiesleads to a rather wide range of outcomes. There is obviously a need for a morerigorous methodological framework. This paper provides a new...

In this paper we compare the predictive abilility of Stochastic Volatility (SV)models to that of volatility forecasts implied by option prices. We develop anSV model with implied volatility as an exogeneous var able in the varianceequation which facilitates the use of statistical tests for...

This paper introduces and surveys ecological-economic analysis ofbiodiversity. It seeks to identify the complex linkages betweeneconomic and ecological systems with a view to a solid exploration ofvaluation issues in biodiversity. Against this background the studyoffers a review of key...

After the Kyoto agreements the need has arisen to trace the implications ofvarious international environmentalstrategies. In this paper, we discuss relevant modelling issues ofincorporating important environmental policy measures in one ofthe popular applied general equilibrium models for...

Convergence in gross domestic product series of five European countriesis empirically identified using multivariate time series models that arebased on unobserved components with dynamic converging properties.We define convergence in terms of a decrease in dispersion over timeand model this...

Various economic theories are available to explain the existence of credit and default cycles. There remains empirical ambiguity, however, as to whether or these cycles coincide. Recent papers_new suggest by their empirical research set-up that they do, or at least that defaults and credit...

This paper investigates business cycle relations among different economies in theEuro area. Cyclical dynamics are explicitly modelled as part of a time series model. Weintroduce mechanisms that allow for increasing or diminishing phase shifts and for time-varyingassociation patterns in different...

The Commonwealth of Virginia abolished parole and reformed sentencing for all felony of-fenders committed on or after January 1, 1995. We examine the impact of this legislationon reported crime rates using different time series approaches. In particular, structuraltime series models are...

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...
