Separability in farm-household economics: An experiment with linear programming
讨论农户生产和消费可分性假设的局限性，通过汤加农户案例，将计量需求估计与线性规划生产模型结合，发现可分性模型在分析消费时优于忽略生产消费联系，但生产侧限制导致线性规划解不现实，阻碍以生产为重点的研究采用该假设。
The assumption of separability between farm-household production and consumption facilitates analysis, but entails several important restrictions. The implications of assuming separability are discussed here in relation to the modelling of a representative Tongan farm-household. Econometric estimation of household demand is coupled with a linear programming (LP) model of farm-household production. When analysing consumer demand, separable farm-household economics is undoubtedly preferable to ignoring the production/ consumption linkages entirely. However, the restrictions which must be imposed on the production side of the separable model are such that a realistic LP solution is unlikely to be obtained. This is likely to be a major deterrent to adopting the separable approach for studies in which the main focus is on production rather than consumption.
