Making it right? Social norms, handwriting and human capital

Inhalt Can early childhood interventions compensate for innate deficits? In this paper, I study the forced right-hand writing of left-handed children (“switching”). While previous literature has found that due to innate cognitive deficits left-handers obtain less human capital and lower wages than right-handers, I find that switched left-handers perform equally well or even better in the labor market than right-handers. Only non-switched left-handers exhibit the deficits of left-handers found in earlier studies. To address potential selection bias, I employ a difference-in-difference approach, where I exploit the rapid decline of switching across cohorts. Cohort trends of the outcome variables of right-handers, who were never switched, are used as a counterfactual for left-handers. Using rich data from the German Socio-Economic Panel (SOEP), I show that the observed differences in outcomes occur due to differential human capital accumulation, rather than cognitive or non-cognitive skills. My findings are consistent with switching compensating for the innate deficits of left-handers.
