I show that the trend towards single households among older nonmarried women, the majority of whom were widows, has been ongoing only since 1940 and investigate the factors that fostered the rise in separate living quarters since mid-century by examining the impact of Old Age Assistance on...

We analyze time use studies to describe how people allocate their time as they age, especially among paid work, unpaid work, leisure, and personal care. We emphasize differences in time allocation between older (i.e., those aged 65+) and younger people; between developed and developing countries;...

The Medicare trust funds face huge prospective deficits by the end of this decade.This paper discusses trends in six areas that bear on the Medicare problem: the number of the elderly, their health status, use of medical care, labor force participation, income, and living arrangements.

This paper presents new evidence on cost-of-living indices and annual inflation rates for the elderly population as well as the general population. It employs a now fairly widely accepted adjustment for the inappropriate treatment of housing in the Consumer Price Index. We disaggregate by...

To assess age-specific infection fatality rates (IFRs) for COVID-19, we have conducted a systematic review of seroprevalence studies as well as countries with comprehensive tracing programs. Age-specific IFRs were computed using the prevalence data in conjunction with reported fatalities four...

Although income and wealth are frequently used as indicators of well-being, they are increasingly augmented with subjective measures such as life satisfaction to capture broader dimensions of individuals' well-being. Based on data from large surveys of individuals, life satisfaction in...

In this paper, we investigate the impact of attending school on body weight and obesity. We use school starting age cutoff dates to compare weight outcomes for similar age children with different years of school exposure. As is the case with academic outcomes, school exposure is related to...

Individuals who are likely to realize the largest benefits from improvements in air quality often depend on other members of their households to make time or monetary contributions to their care. The presence of these dependency relationships among household members poses challenges for benefit...

Forty years ago, 96% of six-year-old children were enrolled in first grade or above. As of 2005, the figure was just 84%. The school attendance rate of six-year-olds has not decreased; rather, they are increasingly likely to be enrolled in kindergarten rather than first grade. This paper documents...

We estimate the effects of having more mature peers using data from an experiment where children of the same age were randomly assigned to different kindergarten classrooms. Exploiting this experimental variation in conjunction with variation in expected kindergarten entry age to account for...
