We study clean energy subsidies in a quantitative climate-economy model. Clean energy subsidies decrease carbon emissions if and only if they lower the marginal product of dirty energy. The constrained-efficient subsidy equals the marginal external cost of dirty energy multiplied by the marginal...

Based on analysis of recent data on the evolution of global temperatures, snow and ice covers, and sea level rise, the Intergovernmental Panel on Climate Change (IPCC) has recently declared that "warming of the climate system is unequivocal." Global surface temperatures, in particular, have...

Government strategies for setting energy prices are not uniform across the Latin America and the Caribbean (LAC) region-- or even across fuels. Instead, they cover a full spectrum, ranging from discretionary price-fixing at one end to pure market-based approaches at the other. In between is a...
