This paper examines the shift in childbirth from home to hospital that occurred in the United States in the early twentieth century. Using a panel of city-level data over the period 1927-1940, we examine the shift of childbirth from home to hospital and analyze the impact of medical care on maternal mortality. Results suggest that increased operative intervention on the part of physicians and a resultant greater risk of infection increased maternal mortality prior to the introduction of sulfa drugs in 1937. However, the introduction of sulfa enabled doctors to reduce maternal mortality by enabling them to do potentially life-saving procedures (such as cesareans) without the risk of subsequent infection. Regressions estimated separately by race suggest that the impact of medical care on mat...

This paper uses a unique data set from 1957 to examine whether or not Blue Cross and Blue Shield suffered from an adverse selection death spiral after for-profit commercial insurance companies entered the market for health insurance. Results suggest that moving to experience rating may have helped the Blues counteract adverse selection in the group health insurance market. Adverse selection posed a greater problem for the Blues in the market for individual health insurance, possibly because of differences in the way the Blues screened potential enrollees relative to commercial insurance companies.

This paper examines the racial gap in infant mortality rates from 1920 to 1970. Using state-level panel data with information on income, urbanization, women's education, and physicians per capita, we can account for a large portion of the racial gap in infant mortality rates between 1920 and 1945, but a smaller portion thereafter. We re-examine the post-war period in light of trends in birth weight, smoking, air pollution, breast-feeding, insurance, and hospital births.

In 1954, the Internal Revenue Service stipulated that employer contributions to the health insurance plans of their employees were to be excluded from employee taxable income. Today, the tax subsidy is major feature of the U.S. health care market. This paper examines the initial effects of the tax subsidy on the demand for health insurance using previously unexamined data from 1953 and 1958. Results suggest that the tax subsidy increased the growth of group insurance, particularly among union members and employed persons. This is a critical effect because group insurance is not only less expensive than individual insurance, but it is also easier to obtain, and households with access to group health insurance are far more likely to purchase health insurance coverage than those without simil...
