Unit 3 Flashcards
Aggregate Demand
All goods/services (real GDP) that buyers are willing/able to purchase at different prices
What is the relationship between price level and real GDP (direct or inverse?)
inverse
Aggregate demand equation
AD= C+I+G+Xn
3 things (effects) that cause AD to slope downward
- Wealth effect
- interest rate effect
- foreign trade effect
wealth effect
higher price levels reduces purchasing power and the quantity of expenditures
Interest rate effect
when price levels increase, lenders charge higher interest rates to get a real return on loans
foreign trade effect
when US Prices rise, foreign buyers purchase less US goods, and Americans buy more foreign goods
shifters of AD (4)
- Change in consumer spending
- changes in investment spending
- changes in govt. spending
- changes in net export spending
things that cause a change in consumer spending
higher incomes, consumer expectations, household debt
things that cause a change in investment spending
real interest rates, future business expectations, taxes
things that cause a change in govt. spending
govt. expenditures, increase in public works programs
things that cause a change in net exports
