The recent revision of the European Commission's Energy Tax Directive intends to tax fuels based on both energy content and related carbon dioxide emissions. To explore the implications of such a tax regime for automobile travel, this paper undertakes a comparative econometric analysis of price...

A procurement approach commonly used for construction projects involves paying a fixed price per unit conducted - that is, unit price contracts. We develop an analytical model to study the optimal procurement quantity and monitoring intensity when the required quantities are uncertain. The...

This paper reports the largest meta-analysis yet of price elasticities of travel demand, covering 167 UK studies and 1,633 elasticities for the surface modes of car, rail, bus, and underground. A large number of influences on price elasticities have been examined and methodological issues...

Dynamics in iron ore markets are driven by changes in economic activities that affect commodity markets, trade flows, and shipping activity and safety. This article investigates the relation between these variables in Southeast Asia and the Australasian region. Steel production in China, Japan,...

We study the impact of car user taxes on vehicle quality and demand for kilometres. First, holding car prices fixed, we find that a higher fuel tax leads households to choose cars of better fuel efficiency, provided that the demand for car use is inelastic. Surprisingly, a higher kilometre tax...

This paper analyses the relationship between traffic volume and maintenance costs, and derives estimates for the cost elasticity and the marginal maintenance cost for pricing decisions. Two types of multi-output cost functions were estimated: a translog form and a hybrid form with output...

This paper is concerned with variations in the efficiency of European air navigation service providers. Much analysis has been conducted on the efficiency of airlines, but less has been done on air traffic control, or strictly air navigation services. The diversity of air navigation service...

Recently, differentiations in airport charges have been the subject of juridical complaints. This study identifies key drivers for differentiated passenger service charges. The results suggest airports tend to apply differentiations in favour of their most important users. This is illustrated by...

Considering body congestion in carriage and vehicle congestion in bottleneck queues in a competitive highway/transit system, we investigate the departure patterns of commuters through analysing the equilibria under three road-use pricing strategies. Each strategy is the combination of a...

Since its introduction in the 1950s, containerised shipping has grown dramatically. Accompanying this growth has been a substantial growth in concentration. In this paper, we theoretically identify the effects of firm growth on concentration, and then examine the determinants of firm growth...
