Steps to reproduce
Download the dataset from the Mendeley Data repository. Import the data into a statistical software environment (Stata). Deflate all nominal monetary variables using Mali’s rural Consumer Price Index (CPI) to obtain real values. Apply natural logarithmic transformations to all variables except precipitation. Conduct unit-root tests (ADF and KPSS) to confirm mixed integration orders (I(0)–I(1)). Estimate a Structural Vector Autoregression (SVAR) model with four lags using short-run (recursive) identification restrictions. Compute impulse response functions (IRFs) and cumulative IRFs to analyze dynamic shock transmission. Perform forecast error variance decomposition (FEVD) to assess the relative contribution of each structural shock. Conduct robustness checks by varying lag length, structural ordering, and subsample periods (1990–2006 and 2007–2023).
