This paper uses a computable general equilibrium (CGE) microsimulation model to explore the distributional and poverty-related effects of price reform in the electricity sector of Mali, a poor country in West Africa. In the first part of the paper we analyze the distribution of electricity in...

Quebec’s forests represent 20% of the Canadian forest and 2% of world forests. They play a major role for habitat preservation, supplying goods and services to the population and hence contributing to the economy of this Canadian province. Climate change (CC) will have an impact on forests...
