This paper tests whether income affects the body weight and clinical weight classification of elderly Americans using a natural experiment that led otherwise identical retirees to receive significantly different Social Security payments based on their year of birth. We exploit this natural...

We study the effects of state hospital regulations intended to increase breastfeeding by requiring certain care standards during the postpartum hospital stay. Policy adoption increased breastfeeding initiation by 3.3-4.1 percentage points (4.2-5.2 percent) and breastfeeding at 3 months...

Nutritional disparities across socioeconomic groups contribute to health inequality in the U.S. This paper studies the role of heterogeneous consumer preferences in food choices and explores pricing policies that can promote healthier eating among disadvantaged consumers. Using detailed...

The decline in the physical stature of the American population for more than a generation beginning with the birth cohorts of the early 1830s was brought about by a diminution in nutritional intake in spite of robust growth in average incomes. This occurred at the onset of modern economic growth...

Little is known about whether breastfeeding may prevent disabilities throughout childhood. We evaluate the effects of breastfeeding on child disability using data from the National Survey of Family Growth merged to the National Health Interview Survey for a large nationally representative sample...

Iodine deficiency is the leading cause of preventable mental retardation in the world today. The condition, which was common in the developed world until the introduction of iodized salt in the 1920s, is connected to low iodine levels in the soil and water. We examine the impact of salt...

We study the causes of "nutritional inequality": why the wealthy tend to eat more healthfully than the poor in the U.S. Using event study designs exploiting supermarket entry and households' moves to healthier neighborhoods, we reject that neighborhood environments have meaningful effects on...

This paper analyzes the impact of paid family leave (PFL) policies on informal and formal care for middle-aged and older adults with disabilities in the U.S., and how the heterogeneous benefits accrue to different families. We use data from the 1998-2018 Health and Retirement Study (HRS) and...

Using data from the National Health Interview Survey (NHIS), we construct two measures of the longevity of older wives and husbands. For definiteness, we focus on couples in which the wife was 60 and the husband 62 in 1988. Our first measure utilizes a 4 x 4 "longevity matrix" in which the bins...
