As a result of the BoJ's large-scale asset purchases, the consolidated Japanese government borrows mostly at the floating rate from households and invests in longer-duration risky assets to earn an extra 3% of GDP. We quantify the impact of Japan's low-rate policies on its government and...

Many environmental hazards produce health effects that take years to arise, but quasi-experimental studies typically measure outcomes and treatment over short time periods. We develop a new approach to overcome this challenge and use it to gauge the effect of exposure to air pollution on US life...

This paper uses U.S. loan-level credit register data and the 2018-2019 Trade War to test for the effects of international trade uncertainty on domestic credit supply. We exploit cross-sectional heterogeneity in banks' ex-ante exposure to trade uncertainty and find that an increase in trade...

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...

Commercial real estate accounts for roughly 20% of the U.S. fixed asset stock, and commercial land use is highly regulated. However, little is known about the quantitative impact of these regulations on economic activity or consumer welfare. This paper develops a spatial general equilibrium...

There is substantial evidence that cost-sharing in medical care constrains total health spending. However, there is relatively little (and unclear) evidence on its health effects, particularly in low- and middle-income countries. This paper re-evaluates the link between outpatient cost-sharing...

We study the effects of job-protected leave policies on intergenerational mobility, long-run child outcomes, and parental decisions (labor market, investments in children, and fertility). We merge rich sources of historical information on family leave policies across the United States since 1973...

We measure the impact of the initial Indian national COVID-19 lockdown on digital activity using browser histories of 1,094 individuals, spanning over 31.5 million website visits on computers and mobile devices. Reflecting the predicted increase in the value of online activity, both men and...

We study the evolution of belief systems that suppress productive effort. These include concerns about the envy of others, beliefs in the importance of luck for success, disdain for competitive effort, and traditional beliefs in witchcraft. We show that such demotivating beliefs can evolve when...

We estimate the effects of government spending along the supply chain using disaggregated U.S. government procurement data. We first identify sectoral public spending shocks and combine them with input-output tables to measure upstream and downstream exposure through the production network. We...
