Replication Package for: "Nonlinear Inflation–Growth Nexus in Asia, Latin America, and Sub-Saharan Africa: A Cross-Regional Institutional Analysis

This replication package contains all data, code, and documentation required to reproduce the empirical results in Botsyoe (2025), "Nonlinear Inflation–Growth Nexus in Asia, Latin America, and Sub-Saharan Africa: A Cross-Regional Institutional Analysis." The paper estimates institutionally conditioned, region-specific inflation thresholds using Hansen's (1999) fixed-effects panel threshold regression across 111 countries in Asia (34), Latin America (30), and Sub-Saharan Africa (47) over 1970–2023. A sign reversal in the inflation–growth relationship is confirmed in every region: below the threshold, inflation is growth-accommodating; above it, the effect turns negative and significant. Key findings include thresholds of approximately 4.87% (Asia), 5.05% (Latin America), and a Francophone–Anglophone divide within SSA (3.84% vs. 5.06%) attributable to CFA franc zone monetary discipline. Institutional quality is shown to moderate both threshold levels and regime-specific growth effects across all regions. Inflation endogeneity is addressed using the lagged US Federal Funds Rate as an external instrument. Contents: Stata do-files for all estimation, robustness checks, and IV diagnostics; master panel dataset and regional subsamples (WDI/WGI/IMF IFS/UNCTAD sources); variable construction notes; and a README with full replication instructions. Software: Stata 16 or later. Required packages: xthreg, xtabond2, xtivreg2. Data sources: World Bank WDI, Worldwide Governance Indicators (WGI), IMF International Financial Statistics (IFS), UNCTAD.本复现包包含复现Botsyoe（2025）发表的论文《亚洲、拉丁美洲与撒哈拉以南非洲的非线性通胀-增长关系：跨区域制度分析》中实证结果所需的全部数据、代码与文档。 该论文采用汉森（1999）提出的固定效应面板门槛回归模型，针对1970—2023年间亚洲（34国）、拉丁美洲（30国）与撒哈拉以南非洲（47国）共计111个国家，估算了受制度约束的区域特定通胀门槛。研究证实各区域内通胀与增长的关联均存在符号反转：当通胀低于门槛值时，通胀对增长具有促进作用；当通胀高于门槛值时，该效应转为负向且显著。核心研究发现包括：亚洲地区的通胀门槛约为4.87%，拉丁美洲地区约为5.05%；撒哈拉以南非洲内部存在法语区与英语区的分化，门槛值分别为3.84%与5.06%，这一差异可归因于非洲金融共同体法郎区（CFA Franc Zone）的货币纪律约束。研究同时表明，制度质量会对所有区域的门槛水平以及不同区制下的增长效应产生调节作用。本文采用滞后的美国联邦基金利率作为外部工具变量，以解决通胀的内生性问题。 本复现包的内容包括：用于所有估计、稳健性检验与工具变量诊断的Stata do文件；主面板数据集与区域子样本（数据源自世界发展指标（WDI）、全球治理指标（WGI）、国际货币基金组织国际金融统计（IFS）以及联合国贸易和发展会议（UNCTAD））；变量构建说明；以及包含完整复现步骤的README文档。 所需软件为Stata 16及以上版本，依赖的扩展包包括xthreg、xtabond2与xtivreg2。 数据来源包括：世界银行世界发展指标（WDI）、全球治理指标（WGI）、国际货币基金组织国际金融统计（IFS）以及联合国贸易和发展会议（UNCTAD）。
