Thus, the first principle of macroeconomic policy is that because only the government can create the investment-grade financial assets that are in short supply in a depression, it is the government’s task to do so. The government must ensure that the money supply matches the full-employment level of money demand, and that the supply of safe savings vehicles in which investors can park their wealth also meets demand.
因此可以归纳出宏观经济政策的第一条原则：因为只有政府才能生产出萧条中紧缺的投资级别金融资产，所以它必须承担这一责任。政府可以确保货币供应与充分就业所需的货币量相符合，并提供足够的安全储蓄工具以供投资者们安置他们的财富。
