CEREAL YIELDS IN FRAGILE STATES: THE ROLES OF ECONOMIC GROWTH, INFLATION, CLIMATE VARIABILITY, AND GOVERNANCE

This repository contains the replication dataset and supporting documentation for the manuscript titled “Macroeconomic Instability, Climate Variability, and Cereal Yields in Fragile States: Evidence from Dynamic Heterogeneous Panels.” The study uses a balanced annual panel covering 15 countries and 315 observations over the period 2002–2022. The archived dataset includes the variables YEAR, COUNTRY, govE, POL, GDPPCC, INF, RF, TEM, POPG, and CY. These correspond to government effectiveness, political stability, GDP per capita, inflation, rainfall, temperature, population growth, and cereal yield. The dataset was compiled from publicly available sources. GDP per capita, inflation, population growth, and cereal yield were drawn from the World Development Indicators (WDI). Government effectiveness and political stability were drawn from the Worldwide Governance Indicators (WGI). Rainfall and temperature were drawn from the World Bank Climate Change Knowledge Portal (CCKP). The repository includes the final panel dataset in Excel and CSV formats, a codebook, source and extraction notes, and country coverage information. For full empirical replication, users should also consult the transformation/estimation files used to generate logged variables and reported regression outputs.本仓库包含题为《脆弱国家的宏观经济不稳定、气候波动与谷物产量：基于动态异质性面板的实证证据》的学术论文的复现数据集与配套支撑文档。 本研究采用2002年至2022年间覆盖15个国家、共315条观测值的平衡年度面板数据。归档数据集包含以下变量：YEAR（年份）、COUNTRY（国家）、govE（政府效能）、POL（政治稳定性）、GDPPCC（人均GDP）、INF（通货膨胀率）、RF（降雨量）、TEM（气温）、POPG（人口增长率）及CY（谷物产量）。 本数据集整合自公开可得的数据源：人均GDP、通货膨胀率、人口增长率及谷物产量数据源自世界发展指标（World Development Indicators, WDI）；政府效能与政治稳定性数据源自全球治理指标（Worldwide Governance Indicators, WGI）；降雨量与气温数据源自世界银行气候变化知识门户（World Bank Climate Change Knowledge Portal, CCKP）。 本仓库包含格式为Excel与CSV的最终面板数据集、变量编码手册、数据源及数据提取说明，以及国家覆盖范围信息。若需完整复现实证结果，使用者还需参考用于生成对数化变量及报告回归结果的转换/估计脚本文件。
