This note estimates the long-run demand for skilled and unskilled labor using panel data for Colombian manufacturing plants. Unobserved heterogeneity and measurement error problems that commonly arise in microdata production estimates are examined. Output measurement errors cause OLS estimators to underestimate the output and wage response of employment demand. Time-difference estimators exaggerate the measurement error biases. Instrumental-variable estimates of the output elasticities are 0.89 and 0.76 and own-wage elasticities are −0.42 and −0.65 for skilled and unskilled labor, respectively. The output elasticity is larger for skilled labor whereas the wage elasticity is larger for unskilled labor in virtually every industry.

This paper explores the link between financial market incompleteness and human capital accumulation. We examine how child school attendance responds to seasonal fluctuations in the income of agrarian households using panel data from rural India. To pinpoint market imperfections, we study responses to aggregate and idiosyncratic, as well as to anticipated and unanticipated, income shocks. Our main finding is that seasonal fluctuations in school attendance are a form of self-insurance, but one which does not result in a substantial loss of human capital on average.
