AP Macroeconomics - Hard Policy Analysis

Front

Bond Prices vs. Interest Rates

Back

There is an inverse relationship: when market interest rates rise, the price of previously issued bonds falls. This is because newer bonds pay higher rates, making existing bonds with lower coupon rates less attractive and cheaper to sell.

Front

Complete Crowding Out

Back

A situation where increased government borrowing fully offsets the expansionary effect of deficit spending. It occurs when the loanable funds market is perfectly inelastic (vertical supply) or when private investment is extremely sensitive to interest rate changes, leaving total aggregate demand unchanged.

Front

Money Market vs. Loanable Funds Market

Back

The **Money Market** determines the short-run nominal interest rate based on liquidity preference (supply of money vs. demand for money). The **Loanable Funds Market** determines the long-run real interest rate based on savings and investment behavior. They are distinct models used for different policy analysis.

Front

Automatic Stabilizers

Back

Mechanisms that automatically counteract economic fluctuations without explicit new legislation, such as progressive income taxes and unemployment benefits. During expansions, they reduce disposable income (taxes rise, benefits fall), cooling demand; during recessions, they increase disposable income, cushioning the downturn.

Front

Exchange Rate Effect on AD

Back

Also known as the net export effect. A higher domestic price level makes domestic goods more expensive relative to foreign goods, reducing exports and increasing imports (Net Exports decrease). This causes the Aggregate Demand curve to slope downward.
