Market Excess Demand in Exchange Economies with Identical Preferences and Collinear Endowments
证明，在价格集合边界附近任意小的邻域内，任何给定的超额需求函数都可以被视为一个由足够多具有相同偏好的个体组成的经济体的超额需求，且个体禀赋可共线选择以产生任意与价格无关的相对财富分布。
In this paper we show that up to an arbitrary small neighbourhood of the boundary of the set of prices any given excess demand function can be considered as the excess demand of an economy with any large enough but finite number of individuals having identical preferences. Moreover, the individual endowments can be chosen collinear and in such a way that they yield any arbitrary price independent distribution of relative wealth.
