The world has pledged to protect 30 percent of its land and waters by 2030 to halt the rapid deterioration of critical ecosystems. We summarize the state of knowledge about the impacts of protected area policies, with a focus on deforestation and vegetation cover. We discuss critical issues...

The European Union designates 26% of its landmass as a protected area, limiting economic development to favor biodiversity. This paper uses the staggered introduction of protected-area policies between 1985 and 2020 to study the selection of land for protection and the causal effect of...

Payments for Ecosystem Services (PES) are a widely used approach for forest conservation through which people are paid to avoid deforesting land they enroll in the program. We present findings from a randomized trial in Mexico that tested whether a PES contract that requires enrollees to enroll...

Two factors have elevated recent academic and policy interest in tropical deforestation: first, the realization that it is a major contributor to climate change; and second, a revolution in satellite-based measurement that has revealed that it is proceeding at a rapid rate. We begin by reviewing...

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...

Quantifying factors giving rise to temporal variation in forest fires is important for advancing scientific understanding and improving fire prevention. We demonstrate that eighty percent of the large year-to-year variation in forest area burned in California can be accounted for by variation in...

Rapid progress has been made in identifying links between human genetic variation and social and behavioral phenotypes. Applications in mainstream economics are beginning to emerge. This review aims to provide the background needed to bring the interested economist to the frontier of...

The governance and transaction cost insights of Oliver Williamson (1975, 1985, 1996, 2010) and Ronald Coase (1937, 1992) have framed antitrust polices and firm management strategies. Transaction cost economics explain efficient governance adaptation. With a focus on private efficiency gains...

The use of private capital to finance biodiversity conservation and restoration is a new practice in sustainable finance. This study sheds light on this new practice. First, we provide a conceptual framework that lays out how biodiversity can be financed by i) pure private capital and ii)...

In an effort to measure and track marine-dependent economic activities, the United States National Oceanic and Atmospheric Administration (NOAA) has developed two statistical tools: The Economics: National Ocean Watch (ENOW) and the Marine Economy Satellite Account (MESA). In both efforts, the...
