By exploiting exogenous variations in air quality during the 2008 Beijing Olympic Games, we estimate the effect of air pollution on mortality in China. We find that a 10 percent decrease in PM₁₀ concentrations reduces the monthly standardized all-cause mortality rate by 8 percent. Men and women...

We empirically test four hypotheses regarding differences between agricultural worker earnings (wages and bonuses) during recession and non-recessionary times, between agricultural worker time use during recession and non-recession times, between outcomes for undocumented and documented workers,...

This paper estimates the production technology of the U.S. computer industry using firm market value to control for the correlation between inputs and unobservable productivity shocks. We show that firm market value can serve as a proxy for unobservable productivity shocks. We also show that...

This study examines legislation that would grant growers termination damages if their contracts are terminated. Our model suggests that, with no contracting frictions, damages would not reduce ex ante efficiency as processors can contract around damages through contract restructuring. Growers...

We investigate the long-term causal impact of PM2.5 on cognition ability among middle-aged and older adults in China. Using a regression discontinuity design we find that a 10-μg/m3 increase in long-term PM2.5 exposure reduces overall cognitive ability score by 0.7 standard deviation (SD). The...

Using individual-level data of antidepressant prescriptions filled and the local bias phenomenon of investors in the United States, we study the effects of stock declines on the psychological health of investors and find that a one standard deviation decrease in local stock returns increases...

China greatly reduced its air pollution over the past two decades. Using firm-level data, we show how the emission reduction was achieved differently by state-owned enterprises (SOEs) and non-state -owned enterprises (NSOEs): SOE cut more emissions and did so by investing in abatement...

This paper examines the relationship between income, pollution, and mortality in China from 1991-2012. Using first-difference models, we document a robust positive association between city-level GDP and life expectancy. We also find a negative association between city-level particulate air...

By exploiting exogenous variation in air quality during the 2008 Beijing Olympic Games, we estimate the effect of air pollution on mortality in China. We find that a 10-μg/m^3 (roughly 10%) decrease in PM_10 concentrations reduces monthly standardized all-cause mortality by 6.63%. The...

Using a dynamic principal-agent model, we analyze termination damages that protect growers from contract termination or non-renewal. We show that government imposed breach damages can be distortionary and may not necessarily lead to increased grower welfare.
