The Loanable Funds Market: practice worksheet
1. The supply of loanable funds primarily comes from:
- (A) Business investment spending
- (B) Household and government saving
- (C) Federal Reserve open market operations

- (A) Supply of loanable funds shifts left, raising the real interest rate
- (B) Demand for loanable funds shifts right, lowering the real interest rate
- (C) Supply shifts right, lowering the real interest rate
- (D) No change, because government borrowing does not affect private markets
3. Crowding out refers to the situation where:
- (A) Private investment increases due to government spending
- (B) Government borrowing raises interest rates, reducing private investment
- (C) Foreign investors leave the country due to economic instability

4. Which of the following would shift the demand for loanable funds to the right?
- (A) A decrease in business optimism about future profits
- (B) A government budget surplus
- (C) An investment tax credit that makes new capital cheaper for businesses

5. In an open economy, higher real interest rates in the U.S. compared to other countries will most likely:
- (A) Cause capital outflows from the U.S.
- (B) Attract foreign capital inflows, increasing the supply of loanable funds
- (C) Have no effect on international capital flows
- (D) Reduce the value of the U.S. dollar
6. The loanable funds market determines:
- (A) The nominal interest rate, controlled by the Federal Reserve
- (B) The real interest rate, through the interaction of saving and investment
- (C) The federal funds rate
- (D) The inflation rate
7. If the government implements a policy that significantly increases business investment tax credits, the most likely effect on the loanable funds market is:
- (A) Supply shifts right, interest rates fall
- (B) Demand shifts right, interest rates rise
- (C) Supply shifts left, interest rates rise
- (D) Demand shifts left, interest rates fall
8. Which of the following would cause the supply of loanable funds to shift right?
- (A) An increase in government deficit spending

- (C) Government tax incentives for retirement savings accounts
- (D) A decrease in business investment
9. When the government runs a budget surplus, the loanable funds market experiences:
- (A) A leftward shift in supply, raising interest rates
- (B) A rightward shift in supply, lowering interest rates
- (C) A rightward shift in demand, raising interest rates
- (D) No effect, as government finances are independent of private markets
10. A decrease in the real interest rate from 6% to 4% would most likely:
- (A) Decrease the quantity of loanable funds demanded
- (B) Increase the quantity of loanable funds demanded (a movement along the demand curve)
- (C) Shift the demand curve to the left
- (D) Have no effect on investment decisions
The Loanable Funds Market: answer key
1. (B) Saving is what feeds the loanable funds market. Households put aside part of their income, and a government running a surplus adds to the pool. Those savings become the funds available for others to borrow. Option A describes the demand side, since businesses are borrowers, not suppliers. Option C confuses the money market with the loanable funds market; the Fed changes the nominal rate there, not the real rate here. Option D is partially relevant in an open economy but isn't the primary source.
2. (A) A bigger deficit means less government saving, so national saving drops and the supply of loanable funds shifts left. Real interest rates rise. That rate increase is what crowds out some business investment projects. Option B is a common mistake; government borrowing affects supply (through reduced national saving), not demand. Option D ignores the whole crowding-out mechanism that shows up on AP free-response questions every year.
3. (B) Government borrowing competes with businesses for the same pool of savings. More borrowers chasing the same savings pushes rates up. Higher rates knock out private projects that only penciled out at the lower rate. That displacement of private investment is crowding out. Option A has the direction backwards. Option D describes a different mechanism tied to tax policy, not borrowing.
4. (C) Investment tax credits make a given project more profitable, so the expected return on borrowed funds rises. More projects now exceed any given interest rate, and demand for loanable funds shifts right. Option A reduces investment demand, shifting it left. Option B increases supply, not demand. Option D shifts supply right, not demand.
5. (B) Foreign investors chase higher returns. U.S. rates above global rates means capital flows in, which expands the supply of loanable funds in the U.S. and pushes rates back down. This is the capital-flow channel that links the loanable funds market to exchange rates and ultimately net exports, and it appears on the AP FRQ nearly every year. Option A has the direction backwards. Option D also contradicts the standard framework, since capital inflows strengthen the dollar rather than weaken it.
6. (B) The loanable funds market settles the real interest rate (adjusted for inflation) where saving and investment balance. The money market handles the nominal rate. Keeping the two separate is essential because using Federal Reserve language in a loanable funds question (or vice versa) costs points on the FRQ. Option C refers specifically to overnight interbank lending, which is a money market concept.
7. (B) Investment tax credits make business investment more profitable after taxes, so firms want to borrow more at every interest rate. Demand for loanable funds shifts right, pushing the real interest rate up. That higher rate may indirectly encourage more saving, but the initial shift is on the demand side. Option A reverses which curve moves.
8. (C) Tax incentives for retirement accounts (like 401(k) or IRA contributions) raise household saving at any given interest rate, which shifts the supply of loanable funds right. Option A reduces supply through higher government borrowing. Option B reduces supply by definition. Option D affects demand, not supply.
9. (B) Surplus means the government is a net saver rather than a borrower. That addition to national saving shifts the supply of loanable funds right, pushing real interest rates down and encouraging private investment. The 1998-2001 Clinton surpluses worked exactly this way. Option A describes the deficit case. Option D ignores the direct link between government saving and national saving.
10. (B) A lower real interest rate is a price change on the loanable funds market, which causes movement along the existing demand curve, not a shift of the curve itself. Projects that weren't profitable at 6% (say, an expected 5% return) now pencil out at 4%, so businesses borrow more. Watch for the distinction between movements along a curve and shifts of the curve because it's a classic FRQ trap.
