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...

We exploit substantial variation in land-market institutions across Indian states and detailed micro household-level panel data to assess the effect of distortions in land rental markets on agricultural productivity. We provide empirical evidence that states with more rental-market activity...

The National Park Service and other agencies have argued that our recreation lands face a crisis of deferred maintenance. This paper evaluates two proposals for funding public lands, increasing gate fees and taxing recreational gear. It analyzes the joint welfare effects of such taxes and the...

Smoke from massive wildfires blanketed Indonesia in late 1997. This paper examines the impact this air pollution (particulate matter) had on fetal, infant, and child mortality. Exploiting the sharp timing and spatial patterns of the pollution and inferring deaths from "missing children" in the...

Little is known about how pollution impacts worker health and workplace safety. This paper leverages high-frequency, plausibly exogenous variation in wildfire smoke to estimate the impact of pollution on workplace injuries. Our analysis draws on unique data we construct through linking...
