Energy efficiency and conservation are considered key means for reducing greenhouse gas emissions and achieving other energy policy goals, but associated market behavior and policy responses have engendered debates in the economic literature. We review economic concepts underlying consumer...

In a 1991 essay in Scientific American, Michael Porter suggested that environmental regulation may have a positive effect on the performance of domestic firms relative to their foreign competitors, by stimulating domestic innovation. We examine the stylized facts regarding environmental...

This paper examines the choice between revenue-raising and non-revenue-raising instruments for environmental protection in a second-best setting with pre- existing factor taxes. We find that interactions with pre-existing taxes influence the costs of regulation and seriously militate against...

This paper uses analytical and numerical general equilibrium models to study the costs of achieving pollution reductions under a range of environmental policy instruments in a second-best setting with pre-existing factor taxes. We compare the costs and efficiency impacts of emissions taxes,...
