为什么在没有充分就业的情况下，贬值会带来产出的增加？

嗨，爱思考的PZer你好：

同学你好，根据原版本书If there is excess capacity in the economy, then by switching demand toward domestically produced goods and services, depreciation of the currency can increase output/
income. Because some of the additional income will be saved, income rises relative to
expenditure and the trade balance improves.

就业不充分时，如果经济处于贬值的状态，本国商品价格相对下降储蓄增加，收入的增加会改善贸易状况。
