Separability in farm‐household economics: an experiment with linear programming
研究了农户生产和消费之间可分性假设的含义,通过汤加农户案例,将家庭需求计量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有用,但生产侧限制导致难以获得现实的线性规划解。
Abstract 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.
