Replication Data for: \"Stimulant or depressant? Resource-related income shocks and conflict\"

Abstract: We provide evidence on the mechanisms linking resource-related income shocks to conflict, focusing on illegal crops. We hypothesize that the degree of group competition over resources and the extent of law enforcement explain whether opportunity cost or contest effects dominate. Combining temporal variation in international drug prices with spatial variation in the suitability to produce opium, we show that higher prices increase household living standards and reduce conflict in Afghanistan. Analyzing shifts in conflict tactics and using geo-referenced data on drug production networks and territorial control highlight the importance of opportunity costs, and reveal heterogeneous effects consistent with our theory. Replication package: The replication package allows the replication of most files and figures in the paper, and comes together with a latex files that allows compiling the document. Confidential data were replaced with random numbers, allowing the package to run through. All decisions and processes are described with sources in the readme.

摘要：本研究聚焦非法作物，为资源相关收入冲击与冲突之间的关联机制提供实证依据。我们提出假说：群体间资源竞争程度与执法力度共同决定了机会成本效应（opportunity cost effect）与争夺效应（contest effect）何者占据主导地位。结合国际毒品价格的时序波动与鸦片（opium）种植适宜性的空间差异，本研究表明，价格上涨能够提升阿富汗家庭的生活水平并降低当地冲突发生概率。通过分析冲突战术的演变，并结合毒品生产网络与领土控制的地理参考数据（geo-referenced data），本研究证实了机会成本效应的重要性，并揭示出与理论假说相符的异质性影响结果。复现工具包（replication package）：本复现工具包可复现论文中的绝大多数文件与图表，附带可用于编译论文文档的LaTeX源文件。机密数据已替换为随机数值，确保工具包可正常运行。自述文件（readme）中已对所有决策与处理流程及对应来源进行了详细说明。
