Summary and main findings
- A large share of cross-country differences in productivity is explained by differences in agricultural productivity.
- Using a combination of sub-national agricultural statistics and geospatial datasets on crop-specific potential yields, the authors study the main drivers of this variation from a macroeconomic perspective.
- Differences in geographically-induced crop-specific comparative advantages can explain a substantial share of the variation in yields across the world.
- Data reveal substantial gaps between potential and observed yields in most countries.
- When decomposing these within-country gaps, crop selection gaps are on average larger than those induced by input usage alone.
- The results highlight the importance of understanding the interaction of geography and crop selection drivers in assessing aggregate agricultural productivity differences.
Methods and data
- Data sources: sub-national agricultural statistics and geospatial datasets on crop-specific potential yields.
- Analytical perspective: macroeconomic decomposition of yield variation into geographically-induced comparative advantages, crop selection, and input usage.
Policy implications and interpretation
- Assessments of aggregate agricultural productivity differences should account for both geography-induced crop-specific comparative advantages and domestic crop selection decisions.
- Narrowing gaps between potential and observed yields requires addressing both crop selection choices and input usage; crop selection gaps are on average larger than input-usage-induced gaps.
