In this journal, van Reeven (2008) develops a model aimed at showing that scale economies on users' time costs would not provide a justification for public transport subsidies. He claims that a profit-maximising operator allowed to take the demand effects of its pricing into account would offer...

A monopolist in public transport may oversupply frequency relative to the social optimum, as van Reeven (2008) demonstrates with homogeneous consumers. This paper shows that oversupply may also occur if this assumption is relaxed. Whether a monopolist oversupplies or undersupplies frequency...

Despite numerous studies showing the effectiveness of speed enforcement, especially automated speed enforcement, in reducing crashes, public debate still continues in regard to the revenue-raising aspect of speed enforcement. Using speed camera enforcement data from the City of Edmonton, this...

In this paper we developed a methodology based on the input-output approach to estimate the effect that charging Heavy Goods Vehicles (HGVs) may have on the Consumer Price Index (CPI). In order to test this methodology, we applied the model to the case study of Spain. We found that the increase...

This paper proposes and analyses a simple model of schedule competition, where transport providers choose service frequency and fares. The key assumptions are that passengers care about average schedule delay, a consequence of committing to travel before knowing their departure times, and that...

This paper proposes a formal model of per capita private car ownership based on very simple and general assumptions on income distribution and consumers' spending decisions. The author justifies a theoretical S-shaped curve describing changes in ownership as a function of average per capita...

This paper studies the competitive and welfare implications when an airport offers airlines the option of sharing its concession revenue. By studying a non-congested airport whose aeronautical charge is regulated, we find that revenue sharing allows the airport and airlines to internalise a...

A growing number of empirical studies involve the assessment of influences on a choice amongst ordered discrete alternatives. Ordered logit and probit models are well known, including extensions to accommodate random parameters and heteroscedasticity in unobserved variance. This paper extends...

Oil spills are a major cause of environmental concern, in particular for Europe. We extend the traditional approach of assessing the welfare losses for individuals potentially affected by an oil spill, by taking into full account the implications of the probabilistic nature of the related...

Van Reeven (2008) argues that the Mohring effect is not relevant to the determination of transit subsidies because a profit-maximising monopolist would supply frequencies that are the same as, or greater than, those that are socially optimal. We find that his results depend on the reduction or...
