This replication package contains all data, code, and documentation required to reproduce the empirical results in Botsyoe (2025), "Institutional Thresholds and the Activation of Human Capital: A Theory of Regime-Contingent Growth in Developing Economies."
The paper develops the Institutionally-Mediated Threshold Activation (IMTA) framework — an overlapping-generations model in which institutional quality governs the minimum public education expenditure required to activate the Lucas–Romer human capital growth mechanism — and validates four theoretical propositions using Hansen's (1999) fixed-effects panel threshold regression (PTR) across 115 developing countries in Sub-Saharan Africa (47), Asia (38), and Latin America (30) over 1970–2023.
Contents: Stata do-files (00–07), master panel dataset and three regional subsamples (WDI/WGI/UNESCO sources), variable construction notes, and a README with full replication instructions.
Key results: Full-sample thresholds of 3.14% (SSA), 4.03% (Asia), and 6.96% (Latin America) of GDP confirm the cross-regional ordering predicted by the IMTA framework. Stability-stratified sub-group estimates with non-overlapping confidence intervals confirm institutional compression of the activation threshold (∂γ*(ι)/∂ι < 0). Causal identification uses FE–IV (Cragg–Donald F = 950.2 for Latin America, 66.9 for Asia) and System GMM with collapsed instruments.
Software: Stata 16 or later. Required packages: xthreg, xtabond2, xtivreg2.
