Improving early prenatal and postnatal conditions account for at least 16 to 17 percent of the decline in ten year mortality rates of 60-79 year olds between 1900 and 1960-80. Historical trends in early prenatal and postnatal conditions imply that while the baby-boom cohort may be particularly...

This paper provides the first estimates of overall CPI bias prior to the 1970s and new estimates of bias since the 1970s. It finds that annual CPI bias was -0.1 percent between 1888 and 1919 and rose to 0.7 percent between 1919 and 1935. Annual CPI bias was 0.4 percent in the 1960s and then rose...

I discuss the health transition in the United States, bringing new data to bear on health indicators, and investigating the changing relationship between health, income, and the environment. I argue that scientific advances played an outsize role and that health improvements were largest among...

The US Civil War provides researchers a unique opportunity to identify wartime leaders and thus to test theories of leadership. By observing both leaders and followers during the war and forty years after it, I establish that the most able became wartime leaders, that leading by example from the...
