	abstract={We estimate the causal effect of schooling on log earnings using instrumental variables (IV), addressing the endogeneity of schooling by using father’s education as an instrument. The IV estimate implies a return of approximately 7.7 percent per additional year of schooling. First-stage and endogeneity tests confirm instrument strength and the need for IV.},
