我们研究一个市场模型，其中有许多不同类型的不可分割的商品出售。货物可以是可替代的，也可以是互补的。每种商品都有多个单位。每个代理人可能消费几种商品，并且在货币方面具有准线性效用。引入了保证瓦尔拉斯均衡存在的一般条件，推广了总替代、强替代、总替代与互补条件。确定了这种新情况的几个特征。提出了一个全局收敛于瓦尔拉斯均衡的价格调整过程。
We study a market model where there are many different types of indivisible goods for sale. The goods can be substitutable or complementary. There are multiple units of each good. Each agent may consume several goods and has quasi-linear utilities in money. A general condition is introduced to guarantee the existence of a Walrasian equilibrium and generalize gross substitutes, strong substitutes, and gross substitutes and complements conditions. Several characterizations of this new condition are identified. A price adjustment process is proposed which converges globally to a Walrasian equilibrium.
