- 1. The Loanable Funds theory We use the term “loanable funds market” to describe the arrangements and institutions by which saving of households is made available to borrowers.
- 2. Factor income Consum ption 1. Leakages must be recycled if total spending is to match full-employment GDP. 2. According to the Classical theory, the loanable funds market acts as a conduit to transfer spending power (S) from households to borrowing units (firms and government units). 3. Saving (S) is the “source” of loanable funds. Saving Nettaxes
- 3. 1. To have a more secure future, to start a business, to finance a child’s education, to satisfy miserliness, . . . 2. To earn interest. We view interest as the “reward for saving” or the “reward for postponing gratification.”
- 4. Interest rate Future value 4% $1,127.27 5% $1,161.47 6% $1,196.68 7% $1,232.93 8% $1,270.24 9% $1,308.65 10% $1,348.18 11% $1,388.88 12% $1,430.77 Value of $1,000 in 3 years at alternative interest rates The opportunity cost of spending now (measured in lost future spending) is positively related to the interest rate.

- 6. •To finance the acquisition of long-lived capital goods. •The rate of interest is the cost of borrowing or the price of loanable funds. •The investment demand curve indicates the level of investment spending at various interest rates. •As the interest rate decreases, more investment projects become attractive in the assessment of business decision- makers—hence, the investment demand function is downward-sloping with respect to the interest rate.
- 7. Investment Demand Trillions of Dollars 0 Interestrate 3% 5% 1.5 Demand for Funds by Business 1.0 A B When the interest rate falls, investment spending and the business borrowing needed to finance it rises.
- 8. Public sector borrowing •Let G denote public sector (or government) spending for goods and services in a year •T is net tax receipts in a year. •If G is greater than T, the the public sector has a budget deficit equal to G – T. •If T is greater than G, then the public sector has a surplus equal to T – G. •If the public sector has a budget deficit, it must borrow.
- 10. Public Sector Borrowing in Classica G = $2 trillion T = $1.25 trillion Therefore, Budget Deficit = G – T = $2 trillion - $1.25 trillion = $0.75 trillion 0.750 5% 3% Government Demand for Funds InterestRate Trillions of Dollars A B

- 14. Why does the loanable funds theory guarantee the validity of Say’s law? S = IP + G - T Quantity of Funds Supplied Quantity of Funds Demanded Now, rearrange the equation above by bringing T to the left side: S + T = IP + G Leakages Injections
- 15. So long as the loanable funds market “clears,” leakages (Saving) will be offset to injections (investment and government spending).

- 17. Changes in government spending, transfer payments, and taxes designed to change total spending in the economy and thereby influence total output and employment.
- 18. The Classical view of Fiscal policy Friends, we believe that fiscal policy is unnecessary and ineffective. The economy is doing just fine without meddling by Washington.
- 19. •Crowding out is the idea that an increase in one component of spending will cause a decrease in other spending components. •An increase in G may cause a decrease in C, IP , or both—that is, government spending may “crowd out” private spending.
