April 2018Geography and Agricultural Productivity: Cross-Country Evidence from Micro Plot-Level Data
with Diego Restuccia: w24532
Why is agricultural productivity so low in poor countries relative to the rest of the world? Is it due to geography or constrained economic choices? We assess the quantitative role of geography and land quality for agricultural productivity differences across countries using high-resolution micro-geography data and a spatial accounting framework. Our rich spatial data provide in each cell of land covering the entire globe actual yields of cultivated crops and potential yields for 18 crops, which measure the maximum attainable output for each crop given soil quality, climate conditions, terrain topography, and a level of cultivation inputs. While there is considerable heterogeneity in land quality across space, even within narrow geographic regions, we find that low agricultural productivit...
January 2017Misallocation, Selection and Productivity: A Quantitative Analysis with Panel Data from China
with Loren Brandt, Jessica Leight, Diego Restuccia: w23039
We use household-level panel data from China and a quantitative framework to document the extent and consequences of factor misallocation in agriculture. We find that there are substantial frictions in both the land and capital markets linked to land institutions in rural China that disproportionately constrain the more productive farmers. These frictions reduce aggregate agricultural productivity in China by affecting two key margins: (1) the allocation of resources across farmers (misallocation) and (2) the allocation of workers across sectors, in particular the type of farmers who operate in agriculture (selection). We show that selection can substantially amplify the static misallocation effect of distortionary policies by affecting occupational choices that worsen the distribution of ...
