我们构建了一个独特的数据集来研究贝宁，加纳，马里和塞内加尔的政治边缘化，交通基础设施公共投资和粮食安全之间的关系。我们首先显示了粮食安全和道路基础设施之间的强有力的关系控制后，已知的影响粮食安全的其他因素，包括气候和土地生产力。为了追踪政治边缘化影响粮食安全的潜在机制，我们研究了它与国家内部道路分配的关系。我们发现支持的论点，即政治因素影响道路的位置后，控制的经济重要性的地区，以及许多其他因素。这一发现对许多替代规范具有稳健性。我们的结论是，政治边缘化地区的道路明显较少，从而支持我们的主张，政治边缘化间接影响粮食安全，破坏了质量和分配的交通基础设施。虽然我们在这里没有建立因果关系，这项研究是第一个在微观层面上实证这种关系。版权所有2013，牛津大学出版社。
We have constructed a unique dataset to study the extent of the relationship between political marginalisation, public investment in transport infrastructure, and food security in Benin, Ghana, Mali and Senegal. We first show a strong relation between food security and road infrastructures after controlling for other factors known to affect food security, including climate and land productivity. To trace a potential mechanism by which political marginalisation impacts on food security, we then look at its relation with the allocation of roads within countries. We find support for the argument that political factors affect the location of roads after controlling for the economic importance of the areas, as well as many other factors. This finding is robust to a number of alternative specifications. We conclude that politically marginalised areas have significantly fewer roads, thus supporting our claim that political marginalisation indirectly affects food security, by undermining the quality and the allocation of transport infrastructures. Although we do not establish a causal effect here, this study is the first to empirically substantiate this relationship at the micro-level. Copyright 2013 , Oxford University Press.
