We study social interactions in the risky behavior of best-friend pairs in the National Longitudinal Study of Adolescent Health (Add Health). Focusing on friends who had not yet initiated a particular behavior (sex, smoking, marijuana use, truancy) by the first wave of the survey, we estimate...

Households' and firms' subjective inflation expectations play a central role in macroeconomic and intertemporal microeconomic models. We discuss how subjective inflation expectations are measured, the patterns they display, their determinants, and how they shape households' and firms' economic...

We examine ten cohorts of male eighth graders in public schools in Chicago, IL: 1995-2004. We find that composite measures of math achievement, reading achievement, and neighborhood SES during elementary school are strong predictors of future felony arraignment and incarceration, even among...

The traditional historical narrative claims that White women were rarely involved in market transactions for enslaved people in the antebellum United States. Using transaction records, notary statements, and runaway advertisements, we provide the first quantitative estimates of the extent of...

Using longitudinal data from the German Socio-Economic Panel, we analyze the effects of exposure to globalization on the fertility and marital behavior in Germany, until recently a lowest-low fertility setting. We find that exposure to greater import competition from Eastern Europe led to worse...
