Who pays for fertilizer-import market power? A CGE-microsimulation analysis for Burkina Faso

Description

This package contains the code and calibration materials needed to reproduce all results, tables, and the figure in the article. It comprises three components. First, a GAMS implementation of a single-country, recursive-dynamic computable general equilibrium model of the PEP-1-t family, extended with an ad valorem fertilizer-import markup, together with the 2016 social accounting matrix for Burkina Faso, the elasticity and calibration files, and the benchmark and counterfactual solution files. Second, a Stata pipeline that couples the CGE model, top-down and bottom-up, to a microsimulation on the EHCVM-2 household survey: it prepares the household data, estimates a QUAIDS demand system, runs the microsimulation, iterates the labor-supply feedback to convergence, and computes the welfare incidence (equivalent variation) and the sensitivity and robustness experiments, all driven by a master do-file. Third, post-processing scripts (Python and JavaScript) that build the manuscript tables and the marginal-cost figure. A README documents the software requirements (GAMS, Stata, Python), the folder structure, and the step-by-step order in which to run the files. The package does not include the raw EHCVM-2 microdata. These are the property of the Institut National de la Statistique et de la Démographie (INSD) of Burkina Faso and are available only under restricted access from INSD; the code documents the variables used and the steps required to reproduce the derived files once access has been granted.
