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,...

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...

Can directed technical change be used to combat climate change? We construct new firm-level panel data on auto industry innovation distinguishing between "dirty" (internal combustion engine) and "clean" (e.g. electric and hybrid) patents across 80 countries over several decades. We show that...
