Output, income, and employment fall when money saved exceeds intended investment, until savings equals investment |
Savings equals investment in equilibrium (ignoring government or foreign sector)
Interest rates fall when money saved exceeds the demand for those funds for investment, until savings equals investment
"In the long run, we're all dead
Demand, particularly intended investment, drives supply |
Capitalist economies tend to full employment, at least in the long run
In equilibrium, aggregate demand (total planned spending) must equal output and income |
Investment and savings are primarily functions of the rate of interest

The paradox of thrift |
|||
Output, income, and employment fall when money saved exceeds intended investment, until savings equals investment |
|||
Supply creates its own demand |
|||
Capitalist economies will normally fail to reach full employment due to insufficient aggregate demand |
|||
Savings equals investment in equilibrium (ignoring government or foreign sector) |
S =I at full employment |
S = I even below the full employment level |
|
Capitalist economies tend to full employment, at least in the long run |
Only the short-run was considered. Governments should act fast in the short-run rather than wait for market forces to fix the economy over time. |

Saving is a leakage out of, and investment is an injection into, the spending flow |
|||
Investment and savings are primarily functions of the rate of interest |
|||
Interest rates fall when money saved exceeds the demand for those funds for investment, until savings equals investment |
|||
In equilibrium, aggregate demand (total planned spending) must equal output and income |
