Almost every aspect of government has an important economic component. A few examples of the kinds of economic policies that exist include: [1] Macroeconomic stabilization policy, which attempts to keep the money supply growing at a rate that does not result in excessive inflation, and attempts to smooth out the business cycle.
The Market for Capital (the Loanable Funds Market) and the Crowding Out Effect. An increase in government deficit spending "crowds out" private investment by increasing interest rates and lowering the quantity of capital available to the private sector [sic].

However, eventually the depreciation rate will limit the expansion of capital: savings will be used up replacing depreciated capital, and no savings will remain to pay for an additional expansion in capital.
Whether an incremental increase to government spending will have a multiplier effect is thought to depend on circumstances in the economy: first, particularly on the extent to which unemployment of resources may be high, so that the additional demand represented by government purchases may be realized by additional production and higher ...
