This code replicates the figures and tables presented in the article “Components of Agricultural Productivity Change: Replication of US Evidence and Extension to the EU”, published in Applied Economics Perspectives and Policy: https://doi.org/10.1002/aepp.13377
The files are as follows:
- 01a-01e: R codes to compile all data needed for estimation. Data are either automatically downloaded by the program, or the links and instructions to do so are provided.
- 02a-02h: R codes to estimate productivity indices and components for the state-level data provided by USDA.
- 03: R codes to estimate the productivity index for the country-level data provided by USDA.
- 04a-04b: R codes to estimate productivity indices and components for the country-level data provided by Eurostat.
- 05a-05b: R codes to estimate productivity indices and components for the country-level International Agricultural Productivity data set provided by USDA.
- 06_Stata_CompareDensities.do: Stata codes to estimate the kernel-analysis procedure
The files in the subfolder "R_aux" contain the data envelopment analysis (DEA) programs to estimate and decompose all productivity indices computed in this study.
The script was successfully run in R version 4.2.0 and Stata version 16.1.
