General equilibrium approaches:

在前面的分析中解决消费者和生产者的目标，我们仅考虑了所谓的部分平衡。请注意，属性“部分”是指在一个市场中仅考虑一个特定商品的市场。就像您已经弄清楚对农产品的需求增加仅由于收入增加而增加的情况，而农业部门的其他活动也没有发生任何事情。也就是说，需求变化对投入和就业等市场的影响尚未生效。看到这些其他市场也将体验到我们已经忽略的变化。

A model that includes the interdependencies of all the markets in the economy can account for the fact that if the equilibrium price in one market changes, the equilibrium prices and hence quantities in other markets are also affected.

To understand such dimensions, we need a model that can accommodate the interactions of all market simultaneously and determine the properties of equilibria in all the markets. We have to develop a general equilibrium model, in contrast to the partial equilibrium models used thus far.
