Using data on U.S. state and federal taxes and transfers over a quarter century, we estimate a regression model that yields the marginal effect of any shift of market income share from one quintile to another on the entire post tax, post-transfer income distribution. We identify exogenous income...

This paper constructs high-frequency and timely income distributions for the United States. We develop a methodology to combine the information contained in high-frequency public data sources--including monthly household and employment surveys, quarterly censuses of employment and wages, and...

Americans are notoriously bad savers. Large numbers are reaching old age too poor to finance retirements that could last longer than they worked. This study uses the 2018 American Community Survey to impute retirement ages for 2019 Survey of Consumer Finance (SCF) respondents. Next, we run the...

There is limited causal evidence on the effects of different public procurement regulations on project quality and value-for-money for projects funded by national governments and foreign aid donors. This paper uses policy and experimental variation to study how two key contracting...

An impulse response is the dynamic average effect of an intervention across horizons. We use the well-known Kitagawa-Blinder-Oaxaca decomposition to explore a response's heterogeneity over time and over states of the economy. This can be implemented with a simple extension to the usual local...

The COVID-19 pandemic triggered a large and immediate drop in employment among US workers, along with major expansions of unemployment insurance and work from home. We use Current Population Survey and Social Security application data to study employment among older adults and their...

This article examines the consequences and causes of low enrollment of Black patients in clinical trials. We develop a simple model of similarity-based extrapolation that predicts that evidence is more relevant for decision-making by physicians and patients when it is more representative of the...

Lack of information and advising prior to college matriculation may contribute to poor post-secondary outcomes among non-traditional students. We conducted a large-scale, multi-arm field experiment with the U.S. Army to investigate whether a package of research-based personalized information and...

We investigate the impact of a set of place-based subsidies introduced in Turkey in 2012. Using firm-level balance-sheet data along with data on the domestic production network, we first assess the policy's direct and indirect impacts. We find an increase in economic activity in...

This paper examines the tradeoffs of monitoring for wasteful public spending. By penalizing unnecessary spending, monitoring improves the quality of public expenditure and incentivizes firms to invest in compliance technology. I study a large Medicare program that monitored for unnecessary...
