Abstract

We examine the link between ethnic diversity and food insecurity. Using data from the Ghana Living Standards Survey, we measure food insecurity using the Food Insecurity Experience Scale and measure ethnic diversity at the district level using information from the Ghana Population and Housing Census. After addressing endogeneity, we find that an increase in ethnic diversity is associated with an increase in food insecurity. This result is robust to different approaches to addressing endogeneity, different measures of ethnic diversity and alternative ways of conceptualising food insecurity. Our findings further show that trust, threat of criminal violence and threat of war/conflict are important channels through which ethnic diversity influences food insecurity.

摘要

我们研究了种族多样性与粮食不安全之间的联系。使用加纳生活标准调查的数据，我们使用粮食不安全经验量表衡量粮食不安全状况，并使用加纳人口和住房普查的信息衡量地区层面的种族多样性。在解决内生性问题后，我们发现种族多样性的增加与粮食不安全的增加有关。这一结果对于解决内生性问题的不同方法、种族多样性的不同衡量标准以及概念化粮食不安全的替代方法来说都是稳健的。我们的研究结果进一步表明，信任、犯罪暴力威胁和战争/冲突威胁是种族多样性影响粮食不安全的重要渠道。
