We categorize the primary incentive-based mechanisms under consideration for addressing greenhouse gas emissions from electricity generation--pricing carbon, setting intensity standards, and subsidizing clean energy--and compare their market outcomes under similar expansions of clean electricity...

Jurisdictions employing emissions trading systems (ETSs) to control emissions often utilize other environmental or energy policies as well, including policies to support renewable energy and reduce energy consumption. Interactions with these other policies lead to different outcomes from what...

The firm response to regulation is seldom as controversial as in the context of fuel economy standards, a dominant policy to reduce emissions from vehicles worldwide. It has long been argued that such standards lead to vehicle weight changes that increase accident fatalities. Using unconditional...

Despite widespread agreement that a carbon tax would be more efficient, many countries use fuel economy standards to reduce transportation-related carbon dioxide emissions. We pair a simple model of the automakers' profit maximization problem with unusually-rich nationally representative data on...

China's recently launched CO2 emissions trading system, already the world's largest, aims to contribute importantly toward global reductions in greenhouse gas emissions. The system, a tradable performance standard (TPS), differs importantly from cap and trade (C&T), the principal emissions...

Many transportation policies indirectly affect vehicle travel and resulting externalities by inducing changes in vehicle scrappage rates. We leverage the staggered removal of state-level safety inspection programs across the United States within an instrumental variables (IV) framework to...
