Article
Average property insurance premiums have risen by more than 30 percent since 2020, and there is wide variation by location. Premiums have risen the most for homeowners in areas with the highest risk of natural disasters such as hurricanes or wildfires.While premiums have always been higher in riskier locations, the relationship between disaster risk and premiums has grown stronger over time. If present trends in the incidence of natural disasters continue, premiums are...
Article
Protracted periods in foster care can lead to negative long-term outcomes for children. Many states have tried to shorten foster care stays by moving children into either permanent adoptive homes or kinship care. While foster parents receive financial support for the children in their care, adoptive parents or kin guardians often receive less — or no — support. In Financial Incentives for Adoption and Kin Guardianship Improve Achievement for Foster Children (NBER...

On July 1, the Program on Children was renamed the Program on Children and Families. This change, which better captures the range of research carried out by its 171 affiliates, in part marks a return to the program’s roots. In 1993, the late Alan Krueger launched an NBER project on the Economics of Families and Children. It subsequently became a program and has been known as the Program on Children since 1997.1 Broadening the program name recognizes the complex web of...

Air pollution has serious and longstanding negative effects on human health. The primary focus of research on air pollution in the United States since the enactment of the Clean Air Act Amendments of 1990 has been the health implications of particulate matter. In comparison, there has been relatively little work on air pollution and health in historical periods, even though air pollution was much higher in earlier times than it is today. Research on historical air pollution...

Article
Social Security Disability Insurance (DI) “family maximum” rules cap the benefits that can be paid to a disabled worker’s family at the lower of 85 percent of the worker’s average indexed monthly earnings and 150 percent of their primary insurance amount. The effect of these rules is that family payments are the same whether a DI beneficiary has one or many dependents, and when DI beneficiaries have low benefit determinations, there are no payments for dependents at...
Article
It costs the government more to cover the same beneficiary under Medicare than Medicaid, according to a study of disabled individuals who aged from one program into the other.In Medicaid vs Medicare: Evidence from Medicaid to Medicare Transitions at 65 (NBER RDRC Paper NB20-15), Timothy Layton, Nicole Maestas, Daniel Prinz, Mark Shepard, and Boris Vabson find that most of the difference stems from higher payment rates to providers rather than from...

Article
As the population ages, the need for surrogate decision-makers for patients near the end of their lives is rising. When hospitalized older adults are unable to actively participate in decisions about their care, surrogates must make choices, often with limited information. Advance care planning with written directives may improve surrogate decision-making, but directives have limitations: preferences may change after completion, directions may not apply to the ultimate...
Article
Between 1995 and 2010, the share of births in Sweden that involved assisted reproductive technologies (ART) rose from 2 to 10 percent.

Immigrants play a significant role in the entrepreneurial landscape. In the United States, immigrants are 80 percent more likely to start businesses than native-born Americans. More than half of America's billion-dollar startup companies trace their roots to immigrant founders. There is limited research, however, on the factors that influence immigrants' decisions about where to locate their startup businesses. In The Effect of Immigration Policy on Founding...
