There is a consensus among economists that a carbon tax is the best approach for addressing the effects of CO2 emissions on the global climate. However, past international agreements on climate change instead specify caps on emissions (a quantity target) for each country. This paper explores...

This paper investigates the impact of carbon pricing on the economy, with a focus on European carbon taxes and the carbon market. Our analysis reveals three key findings. First, while both policies have successfully reduced emissions, the economic costs of the European carbon market are larger...

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...

While carbon pricing, in general, and carbon taxes, in particular, are popular with economists, they are subject to considerable misunderstanding among policy makers and the public. In this paper I consider and refute five myths about carbon taxes: 1) that a carbon price will hurt economic...

I study how policymakers can access and act on the information about climate change damages that is dispersed throughout the economy. I analyze a new dynamic deposit-refund instrument (called "carbon shares") that I show can: i) efficiently price emissions conditional on information, ii)...

Economists have for decades recommended that carbon dioxide and other greenhouse gases be taxed--or otherwise priced--to provide incentives for their reduction. The United States does not have a federal carbon tax; however, many state and federal programs to reduce carbon emissions effectively...

Experiences in real-world pollution markets suggest that firms make persistent errors in forecasting allowance and credit prices that inform their investment decisions. The residual uncertainty characterizing allowance and credit trading means that pollution markets may fail to deliver...

This paper studies the economic impacts of carbon pricing. Exploiting institutional features of the European carbon market and high-frequency data, I document that a tighter carbon pricing regime leads to higher energy prices, lower emissions and more green innovation. This comes at the cost of...

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...

With few exceptions, economic analyses of "cap-and-trade" permit trading mechanisms for climate change mitigation have been based on first-best scenarios without pre-existing distortions or regulations. The reason is obvious: interactions between permit trading and other regulations will be...
