In this article, a model is introduced that has 2 distinguishing features. First, the multidimensional nature of competition in media markets characterized by free access and advertising is acknowledged, through explicit modeling of vertical and horizontal differentiation. Second, the price of...

In this article, we construct a model to study competing payment networks, where networks offer differentiated products in terms of benefits to consumers and merchants. We study market equilibria for a variety of market structures: duopolistic competition and cartel, symmetric and asymmetric...

A recent literature, dealing with special markets characterized by bilateral network externalities, is summarized and critically assessed. Specific features of these markets, in terms of pricing principles and externalities, are discussed first. Afterwards, several issues related to competition...

This paper presents a theoretical and empirical study of the problem of valuation of local public transport services. A contingent valuation exercise, considering two case studies in northern Italy, is illustrated. This serves as a basis for an econometric analysis aimed at highlighting the role...

Relatively small sectoral productivity shocks could lead to sizable macroeconomic variability. Whereas most contributions in the literature analyze the issue of aggregate sensitivity using simple general equilibrium models, a novel approach is proposed in this paper, based on stochastic...

The PESETA research project integrates a set of high-resolution climate change projections and physical models into an economic modelling framework to quantify the impacts of climate change on vulnerable aspects of Europe. Four market impact categories are considered (agriculture, river floods,...

Relatively small sectoral productivity shocks could lead to sizable macroeconomic variability. Whereas most contributions in the literature analyze the issue of aggregate sensitivity using simple general equilibrium models, a novel approach is proposed in this paper, based on stochastic...

This paper deals with the construction, decomposition and comparison of water footprint time series in 40 countries and one aggregate macro-region, in the period 1995-2009. The analysis of the different “footpaths” allows us to investigate on the possible causes behind the time evolution of...
