In the absence of a broad international agreement, national climate policies are less efficient, due to carbon leakage, and more costly, due to causing unemployment and a loss of competitiveness on international markets. As, in many countries, a substantial fraction of emissions results from the...

A carbon tax is an efficient economic instrument to reduce emissions of carbon dioxide released from fossil fuel burning. Its impacts on production of renewable energy depend on how it is designed-particularly in the context of the penetration of biofuels into the energy supply mix for road...

A carbon tax is an efficient economic instrument to reduce emissions of carbon dioxide released from fossil fuel burning. If designed properly, it could also help significantly to promote renewable energy. Using a multi-sector, multi-country computable general equilibrium model this study...
