The Econometrics of Piecewise-Linear Budget Constraints
阐述和综述了当预算约束为分段线性时，估计消费者需求函数的最大似然技术，强调了随机设定（包括偏好异质性和测量误差）的重要性，并讨论了估计与检验中的计量问题。
In this article maximum likelihood techniques for estimating consumer demand functions when budget constraints are piecewise linear are exposited and surveyed. Consumer demand functions are formally derived under such constraints, and it is shown that the functions are themselves nonlinear as a result. The econometric problems in estimating such functions are exposited, and the importance of the stochastic specification is stressed, in particular the specification of both unobserved heterogeneity of preferences and measurement error. Econometric issues in estimation and testing are discussed, and the results of the studies that have been conducted to date are surveyed.
