Automobile gasoline demand can be expressed as a multiplicative function of fuel efficiency, mileage per car and car ownership. This implies a linear relationship between the price elasticity of total fuel demand and the price elasticities of fuel efficiency, mileage per car and car ownership....

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',...

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...

The demand for air transport is largely determined by the spending capacity of customers. Thispaper aims to offer more insight into the determinants of price elasticities in the aviation sector. Itseeks to identify both common and contrasting factors that influence the price elasticities, on...
