在劳动力市场模型中以及在商品不可分割的交换经济中,总替代性被用作保证竞争均衡存在的一种属性。本文提出了一种简单的方法来检查总替代效用函数的不可分割的商品(或雇员)和货币的有限集。凹性是必须满足的条件之一。只有一个其他的,但类似的关系类型必须检查,以保证总的可替代性。
In labor market models as well as in exchange economies with indivisible goodsgross substitutabilityis used as a property to guarantee the existence of competitive equilibria. This paper develops an easy way to check gross substitutability for utility functions concerning a finite set of indivisible goods (or employees) and money. Concavity is one of the conditions that has to be satisfied. Only one other, but similar, type of relation must be checked to guarantee gross substitutability.
