The history of innovation in the chemical industry offers many insights for accelerating energy innovation. In this chapter, we begin by laying out the early history of the chemical industry for an overview of the role innovation has played in its development. We then explore three noteworthy...

Covid-19 is the single largest threat to global public health since the Spanish Influenza pandemic of 1918-20. Was the world better prepared in 2020 than it was in 1918? After a century of public health and basic science research, pandemic response and mortality outcomes should be better than in...

Twenty-seven percent of the Union Army prisoners captured July 1863 or later died in captivity. At Andersonville the death rate may have been as high as 40 percent. How did men survive such horrific conditions? Using two independent data sets we find that friends had a statistically significant...

A key challenge for research on many questions in the social sciences is that it is difficult to link historical records in a way that allows investigators to observe people at different points in their life or across generations. In this paper, we develop a new approach that relies on millions...

This year marks the centennial of the Nineteenth Amendment, which provided American women a constitutional guarantee to the franchise. We assemble data from a variety of sources to document and explore trends in women’s political participation, issue preferences, and partisanship since that...

The Catholic Church has been making saints for centuries, typically in a two-stage process featuring beatification and canonization. We analyze determinants of rates of beatification and canonization (for non-martyrs) over time and across six world regions. The research uses a recently assembled...

Trends in BMI values are estimated by centiles of the US adult population by birth cohorts 1886-1986 stratified by ethnicity. The highest centile increased by some 18 to 22 units in the course of the century while the lowest ones increased by merely 1 to 3 units. Hence, the BMI distribution...

The introduction of the direct reduction (fully-amortized) loan contract to the U.S. residential mortgage market is an important instance of financial innovation. We describe the adoption of this contract within the building and loan (B&L) industry beginning in the 1880s and culminating in the...
