Crowding Out

The government of Verrenport finances a very large permanent increase in spending by issuing an unprecedented volume of government bonds, at a time when the economy is already operating near full employment. Economist Ruth Adeyinka warns of CROWDING OUT. What is she describing?

1. A.That government purchases will physically consume the goods and materials that private firms would otherwise have bought.Incorrect. Crowding out operates through the market for savings and interest rates, not through direct physical competition for goods.
2. B.That heavy government borrowing competes for available savings and pushes interest rates up, so private investment projects become uneconomic and are displaced.Correct. Higher yields needed to place the debt raise borrowing costs economy-wide and reduce private capital spending.
3. C.That the central bank will be forced to buy the bonds, which increases the money supply and produces inflation.Incorrect. That describes monetising the deficit, a different mechanism. Crowding out occurs even when the central bank does not intervene.
4. D.That the increased spending will raise output so much that the economy overheats and unemployment falls below zero.Incorrect. Unemployment cannot fall below zero, and crowding out describes a reduction in private investment, not runaway growth.

Why: Crowding out is the displacement of private sector investment by government borrowing. When the government issues a very large volume of bonds it becomes an enormous additional competitor for the pool of available savings. To place that supply it must offer higher yields, and because government yields anchor the pricing of corporate and mortgage debt, borrowing costs rise across the economy. Businesses then find that projects which were viable at lower rates no longer clear their hurdle rate, so private capital spending falls and partially offsets the stimulus the spending was intended to deliver. The effect depends heavily on the state of the economy. With substantial slack and idle resources, deficit spending can raise output with little upward pressure on rates, so crowding out is small. Near full employment, which is the case described, real resources are already fully employed and the effect is at its strongest, so a larger share of the fiscal expansion simply displaces private activity rather than adding to it.

The federal government finances a large increase in spending by issuing a great deal of new debt. Which effect works against the stimulus the spending was meant to deliver?

1. A.The additional spending is offset dollar for dollar by higher household saving.Wrong. Households may save more against future taxes, but a full dollar-for-dollar offset is not the standard argument.
2. B.Bond prices rise as the new supply arrives, reducing the return available to lenders.Wrong. A flood of new supply pushes bond prices down rather than up, and lower prices mean higher yields.
3. C.The Federal Reserve must sell securities whenever the Treasury issues new debt.Wrong. The Fed's operations are independent of Treasury issuance and are aimed at policy objectives, not at funding.
4. D.Heavy government borrowing pushes interest rates up, discouraging private investment.Correct. Competing for a limited pool of savings raises borrowing costs for everyone, private firms included.

Why: Deficit-financed spending injects demand directly, but the government has to find buyers for the new debt. Attracting them requires offering higher yields, and every private borrower then faces a higher cost of capital, so some corporate investment and household borrowing never happens. That offsetting effect is crowding out, and it is why the net stimulus is smaller than the headline outlay. The effect is mild when idle savings are plentiful and severe when credit is already tight.
