We analyze how a country pursuing a unilateral climate policy may contribute to a reduction in global CO2 emissions in a cost-effective way. To do so its system of energy taxes and subsidies must account for leakage of emissions from the domestic to the foreign economy. We focus on leakage...

We analyse the optimal design of unilateral climate policy in an open economy where the government is committed to a target for reduction of domestic CO2 emissions but where it is also concerned about carbon leakage. We highlight the importance of distinguishing between leakage at the extensive...

We provide evidence of an energy efficiency gap in China. Using an incentivized field experiment, we document that providing information to consumers on the energy costs of lightbulbs significantly affects their willingness to pay for energy efficient bulbs. Unlike previous literature, we do not...

Will a carbon tax improve the welfare consequences of policies to promote electric vehicles? This paper examines when a complementarity could exist between carbon pricing and high electric vehicle adoption. We analyze electricity generation in recent years to show that in several regions, carbon...

Denmark has a highly ambitious goal of reducing greenhouse gas emissions 70 percent below 1990 levels by 2030. While there is general agreement that carbon pricing should be the centerpiece of Denmark’s mitigation strategy, pricing needs to be effective, address equity and leakage concerns,...

The long-term trend toward more work from home due to digitization has found a strong new driver, the Covid-19 pandemic. The profound change in urban mobility patterns supports the often-held view that reducing the number of commuting trips can lower carbon emissions to a certain degree. We...

We develop and implement a new method for identifying wasted subsidies, and use it to provide systematic evidence on the misallocation of carbon offsets in the Clean Development Mechanism—the world’s largest carbon offset program. Using newly constructed data on the locations and...

This paper analyses an electricity market in which a monopolist that employs fossil-fuel base-load and peak-load technologies competes against a fringe of renewable energy (RE) generators. The optimal technology and electricity mix can be decentralised by levying technology-dependent capacity...

We study the spatial misallocation resulting from subsidies for residential solar panels in the US and quantify the associated environmental costs. We build a structural model of solar panel demand and electricity production across the country and estimate the model by combining 1) remotely...

We study the effect of climate policy on companies’ greenhouse gas emissions using emissions data for the headquarters and subsidiaries of the world’s biggest manufacturing, energy, and utility companies. Our results suggest that financial incentives and legal requirements to audit energy...
