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...

Water is scarce in many countries. One instrument to improve the allocation of a scarce resource is (efficient) pricing or taxation. However, water is implicitly traded on international markets, particularly through food and textiles, so that impacts of water taxes cannot be studied in...

This paper analyzes the qualitative properties of a multisectoral, multiregional computable general equilibrium model where some industries include heterogeneous firms as in Melitz (2003). The model, formulated according to Roson, R. and Oyamada (2014), adds endogenous productivity effects to a...

This paper discusses which changes in the architecture of a standard CGE model are needed in order to introduce effects of trade and firm het- erogeneity à la Melitz. Starting from a simple specification with partial equilibrium, one primary production factor and one industry, the framework is...

This paper uses WITCH, an integrated assessment model with a game-theoretic structure, to explore the prospects for, and the stability of broad coalitions to achieve ambitious climate change mitigation action. Only coalitions including all large emitting regions are found to be technically able...

Virtual water trade refers to the implicit content of water in the production of goods and services. When trade is undertaken, there is an implicit exchange of water. Furthermore, when water gets scarce, water intensive goods become more expensive to produce and the economy compensates through...

An integrated assessment model (ENVISAGE), including a CGE-based economic module and a climate module, is used to assess the effects of a variety of economic impacts induced by climate change. These impacts include: sea level rise, variations in crop yields, water availability, human health,...

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...

We use a general equilibrium model of the world economy, and a regional economic growth model, to assess the economic implications of vulnerability from extreme meteorological events, induced by the climate change. In particular, we first consider the impact of climate change on ENSO and NAO...

A Climate Change Damage Function (CCDF) is a reduced form relationship linking macroeconomic aggregates (e.g., potential GDP) to climate indicators (e.g., average temperature levels). This function is used in a variety of studies about climate change impacts and policy analysis. However, despite...
