Compensating Variation and Hicksian Choice Probabilities in Random Utility Models that are Nonlinear in Income
在收入非线性的离散选择模型中推导希克斯需求与补偿变差的分布，给出价格政策变化后支出与选择概率的简单公式，便于福利测量。
In this paper we discuss Hicksian demand and compensating variation in the context of discrete\nchoice. We first derive Hicksian choice probabilities and the distribution of the (random) expenditure\nfunction in the general case when the utilities are nonlinear in income. We subsequently derive exact and\nsimple formulae for the expenditure and choice probabilities under price (policy) changes conditional\non the initial utility level. This is of particular interest for welfare measurement because it enables the\nresearcher to compute the distribution of compensating variation in a simple way.We also derive formulae\nfor the joint distribution of expenditure, the choice before and after a policy change has been introduced.
