We study how the implementation of emissions trading systems (ETS) impacts emissions reductions and the usage of renewable energy using a panel sample of the largest 100 countries worldwide. Exploiting the cross-country variations in ETS implementations, we show that ETS adoption materially...

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 adopt heterogeneous climate policies that vary both in terms of ambition and in terms of policy approach, with some jurisdictions pricing carbon and others subsidizing clean production. We distinguish two types of policy spillovers associated with diverse policy approaches to...

Reductions in greenhouse gas emissions are a global public good, which makes it efficient to act globally when addressing this challenge. We lay out several reasons that high-income countries seeking to mitigate climate change might have greater impact if they invest their resources in...
