A cross‐section analysis of food insecurity in developing countries: Its magnitude and sources
分析了50个缺粮国家粮食不安全的严重程度，指出问题源于国内粮食生产和外汇获取的波动，并探讨了不同国家应对粮食短缺方式的多样性。
Short‐term instability in food supplies continues to be a severe problem for many developing countries. From the viewpoint of an individual country, this problem arises primarily from fluctuations in domestic food production and in foreign exchange availability. The present paper aims to establish the magnitude and seriousness of the problem in a sample of 50 food deficit countries. It also aims to broaden the scope of discussion of the food security problem by taking into account the possibility that food insecurity may manifest itself in a country in a variety of ways which depend in part on the manner in which the domestic authorities respond to periodic shortfalls in food supplies.
