Estimating Mortality Rates for the US Homeless Population Figure

Estimating Mortality Rates for the US Homeless Population


While low socioeconomic status is well known to be associated with heightened mortality risk, little is known about the mortality rate of the most disadvantaged segment of the US population, people experiencing homelessness. In Life and Death at the Margins of Society: The Mortality of the US Homeless Population (NBER Working Paper 31843), Bruce D. MeyerAngela Wyse, and Ilina Logani illustrate the stark health disparities associated with homelessness.

The researchers follow 140,000 people recorded as sheltered and unsheltered homeless during the 2010 Census through 2022, tracking all-cause mortality using administrative data from the Social Security Administration (SSA). They compare homeless individuals’ mortality risk to that of a representative...

Disease and Economic Surveillance during the COVID-19 Pandemic


Policymaking during a novel pandemic requires information about the spread and impact of infection or about the impact of nonpharmaceutical and pharmaceutical interventions. This is also critical for scientific understanding, whether one is developing models of the disease, the economy, or both. However, because the contagion is novel, we may not know what to measure before the event, and our existing data-gathering infrastructure may be lacking. We have to quickly adapt our surveillance, analysis, and models as we learn more about the threat.

This adaptation was on display during the COVID-19 pandemic. I illustrate this with a series of papers that responded to questions from policymakers and were written with coauthors who sacrificed their regular research to assist with the pandemic response. These papers estimated…

Social Security and Retirement around the World

Social Security and Retirement around the World


Over the past 25 years, labor force participation at older ages has increased dramatically. In the 12 countries that are part of the NBER’s International Social Security (ISS) project, participation among those aged 60 to 64 has risen by an average of over 20 percentage points for men and over 25 percentage points for women.

In The Effects of Reforms on Retirement Behavior: Introduction and Summary (NBER Working Paper 31979), authors Axel Börsch-Supan and Courtney Coile report on the most recent work of the ISS project. The current analysis builds on previous project phases which showed that changes in health and education could…

Broadband Internet Access Improves Health Outcomes for Medicare Patients


Access to a high-speed internet connection provides patients with a low-cost means of collecting information related to medical decisions and the quality of medical care providers. In Broadband Internet Access and Health Outcomes: Patient and Provider Responses in Medicare (NBER Working Paper 31579), Jessica Van Parys and Zach Y. Brown link information on broadband availability by ZIP code from the Federal Communications Commission to Medicare claims data from 1999 to 2008. They analyze the effect of high-speed internet access on health outcomes and provider choices for Medicare beneficiaries who are undergoing common procedures.

C-Suite Differences: Public versus Privately Held Firms figure

C-Suite Differences: Public versus Privately Held Firms


Private equity (PE) firms’ business model is to acquire privately held companies, to change their strategy and operations with the goal of improving profitability and growth, and ultimately to sell the companies for a profit. The senior management team is replaced at a majority of private equity acquisitions. More than 40 percent of PE firms report that this is a key way to improve their acquisitions’ success.

In The Market for CEOs: Evidence from Private Equity (NBER Working Paper 30899), Paul Gompers, Steven Kaplan, and Vladimir Mukharlyamov compare the characteristics of CEOs installed by PE firms to the characteristics of those who become...

Jill HorwitzAustin NicholsCarrie H. Colla, and David M. Cutler find that Certificate of Need (CON) laws that apply to magnetic resonance imaging (MRI) and computed tomography (CT) machines reduce the number of low-value uses of these technologies but largely leave high-value care unaffected.

For the first two years of the COVID-19 pandemic, movements in aggregate US import prices were largely explained by fluctuations in a global index of import prices, but after late 2022, idiosyncratic US demand shocks accounted for a larger share of the variation, according to Mary AmitiOleg Itskhoki, and David Weinstein.

The responsiveness of firms’ labor demand to variations in profitable opportunities declined between the 1980s and the 2000s, Russell CooperJohn C. Haltiwanger, and Jonathan Willis find, largely as a result of increased costs of employment adjustment. 

The special status that the United States holds in global safe-asset markets augments its debt capacity by as much as 30 percent, Jason ChoiDuong Q. DangRishabh Kirpalani, and Diego J. Perez find.

All else equal, the observed increase in the spatial dispersion of wages in the US would have increased internal migration in 1990-2013, because migrants are increasingly responsive to earnings levels, but this positive effect on migration was more than offset by rising housing cost disparities that impede internal mobility, William W. Olney and Owen Thompson find.
