摘要翻译:
研究了享乐市场中消费者和供应商具有保留效用且效用函数对价格可分的均衡。有一种不可分割的善,它有不同的品质;每个消费者购买0或1个单位,每个供应商销售0或1个单位。消费者类型、供应商类型和质量可以是离散的,也可以是连续的,在这种情况下,它们可以是多维的。价格起着双重作用:他们把一些代理商排除在市场之外,他们把剩下的人配对。我们定义了均衡价格和均衡分布,证明了均衡存在,研究了均衡价格和均衡分布的唯一性,并证明了均衡是有效的。在存在一个类型连续统的特殊情况下,当满足广义的Spence-Mirrlees条件时,我们证明了纯平衡的存在性,其中需求分布实际上是需求函数,并证明了它在多大程度上是唯一的。其证明依赖于凸分析,并注意用实例来说明该理论。

英文摘要:
We study equilibrium in hedonic markets, when consumers and suppliers have reservation utilities, and the utility functions are separable with respect to price. There is one indivisible good, which comes in different qualities; each consumer buys 0 or 1 unit, and each supplier sells 0 or 1 unit. Consumer types, supplier types and qualities can be either discrete of continuous, in which case they are allowed to be multidimensional. Prices play a double role: they keep some agents out of the market, and they match the remaining ones pairwise. We define equilibrium prices and equilibrium distributions, and we prove that equilibria exist, we investigate to what extend equilibrium prices and distributions are unique, and we prove that equilibria are efficient. In the particular case when there is a continuum of types, and a generalized Spence-Mirrlees condition is satisfied, we prove the existence of a pure equilibrium, where demand distributions are in fact demand functions, and we show to what extent it is unique. The proofs rely on convex analysis, and care has been given to illustrate the theory with examples.
