We document that nearly half of the global decline in agricultural employment was driven by new cohorts entering labor market. A dataset policy reforms supports an interpretation these cohort effects as human capital. Using a model frictional reallocation, we conclude capital growth led to sharp supply, accounting, at fixed prices, for 40 percent decrease employment. This aggregate effect is ha...
