Biomarkers and Long-term Labour Market Outcomes: The Case of Creatine

Using the Young Finns Study (YFS) combined with the Finnish Linked Employer-Employee Data (FLEED) we show that quantities of creatine measured in 1980 prior to labour market entry affect labour market outcomes over the period 1990-2010. Those with higher levels of creatine (proxied by urine creatinine) prior to labour market entry spend more time in the labour market in the subsequent two decades and earn more. Creatine is not associated with high educational attainment.
