The Affordable Care Act and the market for higher education
Investment in human capital is a key determinant of wages and an important contributor to economic growth. However, incomplete markets for health insurance may distort educational incentives because of the link between employment and health insurance. The Medicaid expansion of the Affordable Care Act (ACA) dramatically broadened insurance offerings, and thus may have affected people’s incentives for education. To study how increasing efficiency in insurance markets affects educational investments, we use a triple-difference strategy comparing counties with different levels of uninsurance ...

Is Health Insurance Good for Your Financial Health?
What is the purpose of health care? What is the purpose of health insurance? When people fall ill, they seek health care in order to get better. But insurance has a slightly different function: Its main role is not to protect our health per se, but to protect our finances. For most people, lifetime health expenditures are quite low. However, some people have enormous health costs owing to major illnesses or health conditions. And this is where health insurance comes in?its goal (like that of any other form of insurance) is to protect these individuals against large, and sometimes ruinous, ...

Unequal Burdens: Racial Differences in ICU Stress during the Third Wave of COVID-19
A critical risk during the COVID-19 pandemic has been the possibility of the hospital system becoming overwhelmed. COVID-19 not only has killed nearly 2 percent of people with confirmed infections but causes many more who contract it to develop severe complications that are potentially fatal if not treated in an intensive care unit (ICU). As ICU capacity is based on typical needs for intensive care before the pandemic, a surge of COVID-related ICU patients may leave no room for individuals requiring intensive care for other reasons—such as heart attacks—or may exceed the total ICU ...

The Spread of COVID-19 and the BCG Vaccine: A Natural Experiment in Reunified Germany
As COVID-19 has spread across the globe, several observers noticed that countries still administering an old vaccine against tuberculosis—the BCG vaccine—have had fewer COVID-19 cases and deaths per capita in the early stages of the outbreak. This paper uses a geographic regression discontinuity analysis to study whether and how COVID-19 prevalence changes discontinuously at the old border between West Germany and East Germany. The border used to separate two countries with very different vaccination policies during the Cold War era. We provide formal evidence that there is indeed a ...

Rural Households Hit Hardest by Inflation in 2021-22
To conclude our series, we present disparities in inflation rates by U.S. census region and rural status between June 2019 and the present. Notably, rural households were hit by inflation the hardest during the 2021-22 inflationary episode. This is intuitive, as rural households rely on transportation, and especially on motor fuel, to a much greater extent than urban households do. More generally, the recent rise in inflation has affected households in the South more than the national average, and households in the Northeast by less than the national average, though this difference has ...

Newer need not be better: evaluating the Penn World Tables and the World Development Indicators using nighttime lights
Nighttime lights data are a measure of economic activity whose measurement error is plausibly independent of the errors of most conventional indicators. Therefore, we can use nighttime lights as an independent benchmark to assess existing measures of economic activity (Pinkovskiy and Sala-i-Martin 2016). We employ this insight to find out which vintages of the Penn World Tables (PWT) and of the World Development Indicators (WDI) better estimate true income per capita. We find that revisions of the PWT do not necessarily dominate their predecessors in terms of explaining nighttime lights (and ...

The Affordable Care Act and the COVID-19 Pandemic: A Regression Discontinuity Analysis
Did Medicaid expansion under the Affordable Care Act affect the course of the COVID-19 pandemic? We answer this question using a regression discontinuity design for counties near the borders of states that expanded Medicaid with states that did not. Relevant covariates change continuously across the Medicaid expansion frontier. We find that (1) health insurance changes discontinuously at the frontier, (2) COVID-19 testing is discontinuously larger in Medicaid-expanding states, and (3) the fraction of beds occupied in ICUs is discontinuously smaller in Medicaid-expanding states. We also find ...

Did State Reopenings Increase Social Interactions?
Social distancing—avoiding nonessential movement and largely staying at home—is seen as key to limiting the spread of COVID-19. To promote social distancing, over forty states imposed shelter-in-place or stay-at-home orders, closing nonessential businesses, banning large gatherings, and encouraging citizens to stay home. Over the course of the last month, virtually all of these states have reopened. However, these reopenings were preceded by a spontaneous increase in mobility and decline in social distancing. Did the reopenings decrease social distancing, or did it ratify ex post what was ...

How Have Racial and Ethnic Earnings Gaps Changed after COVID-19?
Racial and ethnic earnings disparities have been salient features of the U.S. economy for decades. Between the pandemic-driven recession in 2020 and the rising inflation since 2021, workers’ real and nominal earnings have seen rapid change. To get a sense of how recent economic conditions have affected earnings disparities, we examine real and nominal weekly earnings trends for Asian, Black, Hispanic, and white workers. We find that average real weekly earnings have been declining in the past year, but less so for Black and Hispanic workers than for white and Asian workers. Black and ...

Nonconforming Preferences: Jumbo Mortgage Lending and Large Bank Stress Tests
The 2010s saw a profound shift towards jumbo mortgage lending by large banks that are regulated under the Dodd-Frank Act. Using data from the Home Mortgage Disclosure Act, we show that the “jumbo shift” is correlated with being subject to the Comprehensive Capital Analysis and Review (CCAR) stress tests, and that financial regulation caused CCAR-regulated banks to change preference for nonconforming relative to conforming loans of similar size. We discuss potential mechanisms through which regulation could have affected bank incentives.
