Climate change is generating demonstrable harm around the world. Political and legal efforts have sought to associate climate impacts with specific emissions, including in recent international policy discussion of Loss and Damage (L&D). However, no quantitative definition of L&D exists, nor does...

Shared socioeconomic pathways (SSPs) are perhaps the most influential economic policy analyses today. My paper evaluates their development, natural associations, logical consequences, and economic identification. All five SSP baseline scenarios are predicting scenarios that historical...

We study the role of trade policy in one of the most pressing climate policy challenges that developing countries face: meeting voluntary emission restraints (VERs). To do so, we develop a general equilibrium trade model that extends Caliendo and Parro (2015) in three dimensions. First, we model...

Forests accompany the cities we build. There are an estimated 5.5 billion urban trees in the United States. Globally, about 25 percent of urban land is covered by tree canopy. This study examines urban forests as a policy tool for air pollution mitigation. We study an afforestation program in...

How much of the economy is focused on protecting, rehabilitating, or managing the environment? To answer this question, we develop a proof-of-concept environmental activity account to quantify the environmental goods and services sector (EGSS) in the United States. Methodologically, we employ a...

Extensive research has documented that elevated air pollution increases mortality and morbidity, with estimates reaching 8 million deaths per year. Many of the world's one billion urban poor face both high ambient concentrations and even higher transient peaks. Should government interventions...

This paper proposes that strong financial, judicial, and labor market institutions provide comparative advantage in clean industries, and thereby improve a country's environmental quality. Five complementary tests support this hypothesis. First, industries that depend on institutions are...

Forestation is viewed as an important means of removing CO₂ from the atmosphere and thereby reducing net CO₂ emissions. But how much CO₂ can be removed, and at what cost? Focusing on forested and forestable areas in South America, and using spatially disaggregated data, we estimate a...

How responsive to health shocks are healthcare systems in the developing world? Developing countries are known to have both lower levels of hospital infrastructure and serious health shocks driven by air pollution. These shocks are transitory and may be marginal relative to other health demands,...

Historically coal has offered both benefits and costs to urban areas. Benefits include coal's role in fueling industry and thus employment. The primary costs are air pollution and its impact on human health. This paper starts by using a Rosen-Roback style model to examine how differences in...
