较少的国家。假设教育只影响劳动效率的水平。再假设这两个国家在其他方面是相同的：它们有相同的储蓄率、相同的折旧率、相同的人口增长率和相同的技术进步率。这两个国家都可以用索洛模型来描述，并且都处于其稳定状态。你预期以下变量会是多少？

a．总收入增长率。

b．人均收入水平。

c．资本的实际租赁价格。

d．实际工资。

The amount of education the typical person receives varies substantially among countries. Suppose you were to compare a country with a highly educated labor force and a country with a less educated labor force. Assume that education affects only the level of the efficiency of labor. Also assume that the countries are otherwise the same: they have the same saving rate, the same depreciation rate, the same population growth rate, and the same rate of technological progress. Both countries are described by the Solow model and are in their steady states. What would you predict for the following variables？

a．The rate of growth of total income.

b．The level of income per worker.

c．The real rental price of capital.

d．The real wage.
