Financial Liquidity as an Independent Buffer Against Foot-and-Mouth Disease–Related Income Vulnerability in Mixed-Species Smallholder Farms

Abstract

Complete reproducibility package for a study testing whether farm-household financial liquidity (cash relative to debt) is associated with reduced FMD-attributable income vulnerability independently of off-farm income diversification, using survey data from 286 mixed-species smallholder farms in Samsun Province, Turkiye, during the 2022-2023 production period, which coincided with a confirmed FMD incursion. Includes: Python source code reproducing dataset construction, descriptive statistics, OLS and fractional logit regression (main-effects and interaction models), outcome-decomposition and trimmed-sample robustness checks, VIF diagnostics, an Oster (2019) coefficient-stability bounding analysis for unobserved confounding, a minimum-detectable-effect precision analysis, a stratum-heterogeneity test, and all reported figures; The complete farm-level analytical dataset (N=286 farms) and the original raw survey file; Full documentation (codebook, data description with variable-level provenance and known data-quality notes, reproducibility checklist, and a step-by-step replication guide). The study finds that net financial liquidity is negatively associated with FMD-attributable income vulnerability under both OLS and fractional logit specifications, that this association is robust to outlier trimming and to a formal bound on unobserved confounding, and that no evidence of interaction with off-farm income diversification or heterogeneity across farm-size strata was detected. This package is organized around the study itself rather than any single journal submission, so that it remains valid regardless of the eventual publication venue or manuscript title.
