Agricultural Commercialisation and Food Security in Rural Economies: Malawian Experience
研究了经济作物采纳对农户营养结果的影响，发现生产与消费决策不可分离，农业收入向食品支出和膳食改善的传导较弱。
This paper contributes to the debate on the nutrition-related outcomes of cash crop adoption by using a model with essential heterogeneity and a semi-parametric estimation technique. The model explicitly frames non-separability between production and consumption decisions of farming households providing an original test of separability. The empirical application is run using Malawian data. The results imply rational anticipations and decision process of agrarian households relative to the crop portfolio choice, disparate strength of market barriers faced by the farmers, non-separability between production and consumption decisions and a weak transmission from agricultural incomes to higher food expenditures and better diet.
