We study the implications of vertical integration in logistics and transport operations for welfare-optimal port access charges and hinterland congestion tolls. We show that, first, vertical integration of terminal operators and transport firms does not affect the optimal congestion toll rule...

In this paper, we take a political economy approach to study the introduction of urban congestion tolls, using a simple majority voting model. Making users pay for external congestion costs is for an economist an obvious reform, but successful introductions of externality pricing in transport...

In this paper we study the taxation of car ownership, car use and public transport in the presence of externalities within the framework of a discrete/continuous choice model. We first derive optimal taxes in a simplified setting, emphasizing the specific role of fixed car ownership taxes and...

Social conflicts are a serious obstacle to economic growth in many Latin American societies, affecting economic activity both in the short- and the long-run. The purpose of this paper is twofold. First, we develop a methodology to estimate the direct, short-run impact of frequently occurring...

This note proposes a new decomposition of the Malmquist productivity index to account for changes in plant capacity utilisation. Using a primal, non-parametric specification of technology, the Malmquist index is decomposed into technical efficiency change, variations in plant capacity...

This paper deals with costs-benefit analysis of investment in transport infrastructure. Its contribution is twofold. Firstly, we develop a general equilibrium model to explore the impact of a small budgetary-neutral investment in transport infrastructure in a second-best setting, where other...

We consider a model of urban transport with two trip purposes, commuting (assumed perfectly complementary to labour supply) and non-commuting, to analyse the effects of transport tax reform on the value of time and marginal external congestion costs. Higher commuting taxes plausibly reduce time...

The purpose of this paper is to analyse optimal two-part tariffs in the presence of externalities within the framework of a model of discrete choice. The prototype application of the model is optimal taxation of car ownership and car use to correct for external costs. The externality we consider...

We consider binary choices on the trade-off between money and travel time, and formulate a model of reference-dependent preferences based on a linear reference-free utility function. Reference-dependence is captured by value functions that are centered at the reference. The model predicts a...

In this paper, we consider a region that invests in infrastructure used by both local demand and through transport. We then compare transport systems that have, for a given capacity, the same total infrastructure cost but vary in the proportion of fixed costs and variable capacity costs. We...
