Margaret Sanger established the first birth control clinic in New York in 1916. From the mid-1920s, "Sanger clinics" spread over the entire U.S. Combining newly digitized data on the roll-out of these clinics, full-count Census data, and administrative vital statistics, we find that birth...

This paper empirically examines the degree of persistence in four precious metal prices (i.e., gold, palladium, platinum, and silver) during the last four U.S. recessions. Unit root tests and fractional integration techniques suggest that gold still is the most prominent safe haven asset within...

This paper examines ethnicity among highly skilled immigrants to the United States. The paper focuses on five classic components of ethnicity - country of birth, race, skin color, language, and religion - among persons admitted to legal permanent residence in the United States in 2003 in the...

Nearly a quarter of Mexico's workforce is self-employed. In the United States, however, rates of self-employment among Mexican Americans are only 6 percent, about half the rate among non-Latino whites. Using data from the Mexican and U.S. population census, we show that neither industrial...

This paper examines the US gun-related murder (GM) rate and places it in an international context. The US GM rate is 27 times the average rate for 22 other developed countries (ODC). Its gun ownership rate is 5.4 times that of ODC and the murder rate per gun is 5 times that of ODC. Thus, as is...

Social scientists have long documented that many components of socioeconomic status such as income and education have strong ties across generations. However, health status, arguably a more critical component of welfare, has largely been ignored. We fill this void by providing the first...

This paper studies how birth town migration networks affected long-run location decisions during historical U.S. migration episodes. We develop a new method to estimate the strength of migration networks for each receiving and sending location. Our estimates imply that when one randomly chosen...

Manufacturing accounts for more than three-quarters of U.S. corporate patents. The competitive shock to this sector emanating from China's economic ascent could in theory either augment or stifle U.S. innovation. Using three decades of U.S. patents matched to corporate owners, we quantify how...

We discuss the effects of offshoring on the labor market in a matching model with endogenous adjustment of educational skills. We carry out a comparative statics analysis and show that offshoring leads to a restructuring of the economy through skill-biased technical change (SBTC) where overall...
