Studies in the Economics of Aging is the fourth book in a series from the National Bureau of Economic Research that addresses economic issues in aging and retirement. Building on the research in The Economics of Aging (1989) , Issues in the Economics of Aging (1990), and Topics in the Economics of Aging (1992), this volume examines elderly population growth and government spending, life expectancy and health, saving for retirement and housing values, aging in Germany and Taiwan, and the utilization of nursing home and other long-term care.

Japanese and American economists assess the present economic status of the elderly in the United States and Japan, and consider the impact of an aging population on the economies of the two countries.

With essays on labor force participation and retirement, housing equity and the economic status of the elderly, budget implications of an aging population, and financing social security and health care in the 1990s, this volume covers a broad spectrum of issues related to the economics of aging. Among the book's findings are that workers are retiring at an increasingly earlier age in both countries and that, as the populations age, baby boomers in the United States will face diminishing financial resources as the ratio of retirees to workers sharply increases.

This work analyzes the effects of prices, taxes, income, and anti-smoking regulations on the consumption of cigarettes in California (a 25-cent-per-pack state tax increase in 1989 enhances the usefulness of this exercise). Analysis is based on monthly time-series data for 1980 through 1990. Results show a price elasticity of demand for cigarettes in the short run of -0.3 to -0.5 at mean data values, and -0.5 to -0.6 in the long run. We find at least some support for two further hypotheses: that antismoking regulations reduce cigarette consumption, and that consumers behave consistently with the model of rational addiction.

This study used 1982-1986 data on 262 private community hospitals to evaluate the effects of selective contracting for inpatient services by California's Medicaid program. Selective contracting by Medicaid significantly reduced the rate of inflation in average costs per admission and per patient day, while slightly increasing average lengths of patient stays. Private sector contracting also reduced cost inflation rates significantly and caused small, non-significant, reductions in lengths of stays. Hospital savings in 1986 due to Medicaid selective contracting were $836 million, 7.6% of what hospital expenditures would have been in the absence of contracting.
