Question

leakage(泄露）在宏观经济学中怎么理解？

关于定义和内容。

Answer 1

leakage is the non-consumption uses of income, including saving, taxes, and imports. In the Keynesian injection-leakage or circular flow model, leakages are combined with injections to identify equilibrium aggregate output. The model is best viewed as a circular flow between national income, output, consumption, and factor payments. Savings, taxes, and imports are "leaked" out of the main flow, reducing the money available in the rest of the economy.
