Food insecurity, income inequality, and the changing comparative advantage in world agriculture
探讨亚洲土地贫乏国家在经济发展中面临的粮食不安全、收入不平等和比较优势下降问题，并提出亚洲、撒哈拉以南非洲和拉丁美洲应分别采取不同策略以避免全球粮食短缺加剧贫困。
Abstract I would like to argue in this article that in the process of economic development in land‐poor countries in Asia, agriculture faces three distinctly different problems: food insecurity, sectoral income inequality, and the declining food self‐sufficiency associated with the declining comparative advantage in agriculture at the high‐income stage. Massive imports of food grains to Asia, if they occur, will aggravate the world food shortage, which will have significant implications for the poverty incidence in the world. I argue that in order to avoid such a tragedy, Asia should expand farm size to reduce labor cost by adopting large‐scale mechanization, sub‐Saharan Africa should realize a green revolution in grain production, and Latin America should further expand its grain production capacity.
