This study investigates the role of institutions in environment–health outcomes nexus in sub-Saharan African over the period 1996–2016. The study employs different surrogates for capturing the three key variables of concern. These include institutions consisting of control of corruption, government effectiveness, and regulatory quality; environment comprising of carbon emissions and ecological footprints; and health outcomes involving human longevity, child mortality and health expenditures respectively. The study is based its empirical estimations on system of generalized method of moments, of which the following findings are established: First, environmental degradation captured with carbon emissions and ecological footprint is found to reduce human life expectancy by substantial statistical magnitudes. Second, carbon emissions are found to amplify the infant mortality rates, even when the variable interacts with institutional quality variables like government ineffectiveness and poor regulatory quality. Third, both carbon emissions and ecological footprint are found to escalate the cost of health expenditure, but with the dominating influence of the former over that of the latter. Fourth, the defective nature of the African institutional environment receives further empirical validation. Lastly, some other auxiliary variables specific to each health surrogate are also acknowledged. On the policy ground, reducing carbon emissions and strengthening institutional environment hold the key to improving health and other health-related outcomes.

机构在环境-健康成果中的作用Nexus:撒哈拉以南非洲的经验证据

本研究调查了1996-2016年间机构在撒哈拉以南非洲环境与健康结局之间的作用。该研究采用了不同的替代方法来捕获所关注的三个关键变量。这些机构包括控制腐败,政府效力和监管质量的机构;由碳排放量和生态足迹组成的环境;和健康成果分别涉及人类寿命,儿童死亡率和卫生支出。这项研究基于广义矩法的经验估计,并建立了以下发现:首先,发现碳排放和生态足迹捕获的环境退化会大幅降低人类的预期寿命。第二,即使该变量与诸如政府无效和监管质量不佳之类的机构质量变量相互作用时,也发现碳排放会增加婴儿死亡率。第三,发现碳排放量和生态足迹都会使卫生支出的成本上升,但前者的影响要大于后者。第四,非洲体制环境的缺陷性质得到了进一步的经验验证。最后,还承认了针对每个健康代理的其他一些辅助变量。在政策基础上,减少碳排放和加强体制环境是改善健康状况和其他与健康相关的结果的关键。即使变量与体制质量变量(如政府无效和监管质量不佳)相互影响。第三,发现碳排放量和生态足迹都会使卫生支出的成本上升,但是前者的影响要大于后者。第四,非洲体制环境的缺陷性质得到了进一步的经验验证。最后,还承认了针对每个健康代理的其他一些辅助变量。在政策基础上,减少碳排放和加强体制环境是改善健康状况和其他与健康相关的结果的关键。即使变量与体制质量变量(如政府无效和监管质量不佳)相互影响。第三,发现碳排放量和生态足迹都会使卫生支出的成本上升,但前者的影响要大于后者。第四,非洲体制环境的缺陷性质得到了进一步的经验验证。最后,还承认了针对每个健康代理的其他一些辅助变量。在政策基础上,减少碳排放和加强体制环境是改善健康状况和其他与健康相关的结果的关键。但是前者的影响力要强于后者。第四,非洲体制环境的缺陷性质得到了进一步的经验验证。最后,还承认了针对每个健康代理的其他一些辅助变量。在政策基础上,减少碳排放和加强体制环境是改善健康状况和其他与健康相关的结果的关键。但是前者的影响力要强于后者。第四,非洲体制环境的缺陷性质得到了进一步的经验验证。最后,还承认了针对每个健康代理的其他一些辅助变量。在政策基础上,减少碳排放和加强体制环境是改善健康状况和其他与健康相关的结果的关键。
