A well-known principle of welfare economics states that an efficient resources allocation can be achieved in a competitive economy when market prices are in line with social marginal costs. When applied to the transport sector, this implies that the price of the various transport modes should be...

An integrated assessment model is used to simulate the introduction of various emissions trading schemes based on the Kyoto protocol on the reduction of greenhouse emissions. The implications of the various systems in terms of income distribution are illustrated, and it is claimed that the issue...

Markets for transport are often characterised by unequal demand in both directions: every morning during peak hours the trains are crowded while moving towards the direction of large cities, whereas they may be almost empty in the other direction. In this paper we discuss the implications of...

This paper analyses some of the economic issues involved in the diffusion of modern intermodal technologies and the impact of intermodality on the functions performed by nodes in transportation networks. Two simple economic models are presented: the first considers why an intermodal transport...

The carbon emissions abatement, undertaken by some countries, may induce other countries to increase their own emissions. This effect, known as "carbon leakage", may be due to rather different mechanisms. The simplest case is when outside countries do not change their environmental policies and...

The economy-wide implications of sea level rise in 2050 are estimated using a static computable general equilibrium model. Overall, general equilibrium effects increase the costs of sea level rise, but not necessarily in every sector or region. In the absence of coastal protection, economies...

This paper studies the economic implications of climate-change-induced variations in tourism demand, using a world CGE model. The model is first re-calibrated at some future years, obtaining hypothetical benchmark equilibria, which are subsequently perturbed by shocks, simulating the effects of...

A dynamic general equilibrium model of the Italian economy is used to assess the impact of carbon taxation (or auctioned carbon permits), where additional revenue is used to cut either existing taxes on labour or on capital income. Simulation results do not support the existence of the so-called...

International trade negotiations have recently tackled the issue of possible free trade restrictions, justified - among others - on the basis of environmental concerns. Also, some analyses of international environmental agreements (especially in the field of climate change) have highlighted the...

Agricultural sectors play a key role in the economics of climate change. Land as an input to agricultural production is one of the most important links between economy and the biosphere, representing a direct projection of human action on the natural environment. Agricultural management...
