|February 2017||Land Misallocation and Productivity|
with Diego Restuccia: w23128
Using detailed household-level data from Malawi on physical quantities of outputs and inputs in agricultural production, we measure total factor productivity (TFP) for farms controlling for land quality, rain, and other transitory shocks. We find that operated land size and capital are essentially unrelated to farm TFP implying substantial factor misallocation. The aggregate agricultural output gain from a reallocation of factors to their efficient use among existing farmers is a factor of 3.6-fold. We directly link factor misallocation to severely restricted land markets as the vast majority of land is allocated by village chiefs and not marketed. In particular, the output gain from reallocation are 2.6 times larger for farms with no marketed land than for farms that only operate marketed...
|September 2009||Methods versus Substance: Measuring the Effects of Technology Shocks on Hours|
with José-Víctor Ríos-Rull, Frank Schorfheide, Cristina Fuentes-Albero, Maxym Kryshko: w15375
In this paper, we employ both calibration and modern (Bayesian) estimation methods to assess the role of neutral and investment-specific technology shocks in generating fluctuations in hours. Using a neoclassical stochastic growth model, we show how answers are shaped by the identification strategies and not by the statistical approaches. The crucial parameter is the labor supply elasticity. Both a calibration procedure that uses modern assessments of the Frisch elasticity and the estimation procedures result in technology shocks accounting for 2% to 9% of the variation in hours worked in the data. We infer that we should be talking more about identification and less about the choice of particular quantitative approaches.
