According to Keynes, the following actions may lead to an increase in the level of output

and employment:

[1] The money supply can be decreased, leading to higher interest rates and lower

inflation.

[2] Both taxation and government spending can be decreased to allow an increase in

consumption spending by households.

[3] Increasing the budget deficit and more borrowing by the government.

[4] All of the above.

[5] None of the above.
