Existence of Equilibria in Economies with Bads
研究存在无限消费者且部分商品为有害品（带来负效用）的交换经济，给出无竞争均衡的例子，并说明有限经济中均衡分配的一致可积性条件可能失效。
We consider an exchange economy in which there are infinitely many consumers and some commodities are bads, that is, cause disutility to consumers. We give an example of such an economy for which there is no competitive equilibrium or its variants (quasi- or pseudo-equilibrium), and an example of the failure of the so-called uniform integrability condition of equilibrium allocations of increasingly populous finite economies.
