Supplement, data and code: "Coastal Proximity and Individual Living Standards: Econometric Evidence from Geo-Referenced Household Surveys in Sub-Saharan Africa"

This fileset contains the supplement, the data and the replication code for the paper "Coastal Proximity and Individual Living Standards: Econometric Evidence from Geo-Referenced Household Surveys in Sub-Saharan Africa" <br> Abstract: We investigate geo-referenced household-level data consisting of up to 128,609 individuals living in 11,261 localities across 17 coastal sub-Saharan African countries over 20 years. We analyze the relevance of coastal proximity, measured by geographic distance to harbors, as a predictor of individual economic living standards. Our setting allows us to account for country-time fixed effects as well as individual-specific controls. Results reveal that individuals living further away from the coast are significantly poorer measured along an array of welfare indicators. Our findings are robust to the inclusion of other geographic covariates of development such as climate (e.g. temperature, precipitation) or terrain conditions (e.g. ruggedness, land suitability). We also explore mechanisms through which coastal proximity may matter for individual welfare and decompose the estimated effect of coastal proximity via formal mediation analysis. Our results highlight the role of human capital, urbanization as well as infrastructural endowments in explaining within-country differences in individual economic welfare.

摘要：本研究使用20年间覆盖撒哈拉以南非洲17个沿海国家、11261个调查点、共计多达128609名个体的地理参考家庭层面微观数据，探究以到港口的地理距离衡量的沿海区位对个体经济生活水平的预测效力。本研究设定可控制国家-时间固定效应与个体层面控制变量。结果显示，基于一系列福利指标测算，居住地点距海岸越远的个体贫困程度显著更高。研究结论在纳入其他发展相关地理协变量（如气温、降水等气候因素，或崎岖度、土地适宜性等地形条件）后依然稳健。本研究同时探讨了沿海区位影响个体福利的作用机制，并通过正式中介分析拆解了沿海区位的估计效应。结果表明，人力资本、城市化水平与基础设施禀赋在解释一国内部个体经济福利差异中发挥重要作用。
