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...

Climate change not only impacts production and market consumption, but also the relative scarcity of non-market goods, such as environmental amenities. We study fundamental drivers of the resulting relative price changes, their potential magnitude, and their implications for climate policy in...

We study how the scarcity of non-market goods, such as environmental amenities, affects the economic appraisal of climate policy. To this end, we perform a comprehensive analysis of the change in relative prices of non-market goods in the widespread climate-economy model DICE. We show that DICE...

This paper is a revised version of: "https://ssrn.com/abstract=2667972" https://ssrn.com/abstract=2667972.The Analytic Climate Economy (ACE) closes a gap between analytic climate change assessments and quantitative numeric integrated assessment models (IAMs) used in policy advising. Its...

Conventionally, benefit-cost analysis focuses on economic efficiency, summing the values of a policy’s costs and benefits based on the preferences of those affected. There is widespread agreement that it should be supplemented with information on how the impacts are distributed across...

Benefit-cost analysis and other forms of economic evaluation are powerful tools, encouraging the systematic collection and assessment of the evidence needed to support sound policy decisions. In low-and middle-income countries, where resources are very scarce and needs are very great, such...

In benefit-cost analysis, ideally the values placed on nonfatal risk reductions would reflect the preferences of those affected by a policy; i.e., individuals’ willingness to exchange their own income to achieve a reduction in their own risk. Presumably, this willingness to pay (WTP) accounts...

The paper analyzes optimal climate policy under uncertainty. It endows a recent quantitative analytic integrated assessment model (IAM) with long-run risk, adapting methods from the asset pricing literature to deal with endogenous climate risk. The model solves in closed-form for general degrees...

This paper offers a framework for regulating internalities. Using a simple economic model, we provide four principles for designing and evaluating behaviorally-motivated policy. We then outline rules for determining which contexts reliably reflect true preferences and discuss empirical...
