Ethnic Diversity and Food Insecurity: Evidence from Ghana
利用加纳生活水平调查和人口普查数据，研究发现地区族群多样性增加会加剧粮食不安全，信任、犯罪暴力和战争冲突威胁是重要传导渠道。
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.
