This study examines the influence of business cycles in childhood on economic performance later in life. I relate unemployment rates between the year before one's birth and the year of one's 15th birthday to schooling, employment, and income as an adult. The analysis exploits variation in macroeconomic conditions across states over time. I address a number of identification challenges related to cohort effects, linear trends, current events, and economic persistence. The caregiving behaviors and background characteristics of parents are also studied. The average unemployment rate in childhood normally has a negative effect on human capital in adulthood.
