Chapter 8 Flashcards
aggregate expenditure
total spending in the economy
planned aggregate expenditure
consumption (C) + planned investment (I) + government purchases (G) + net exports (NX)
macroeconomic equilibrium
when total spending (planned aggregate expenditure) equals total production (GDP)
when planned aggregate expenditure is greater than GDP, inventories will ___, and GDP and total employment will ___
decline, increase
when planned aggregate expenditure is less than GDP, inventories will ___, and GDP and total employment will ___
increase, decline
consumption level variables
current disposable income, household wealth, price level, and interest rate
consumption function
the relationship between consumption spending (y-axis) and disposable income (x-axis)
autonomous consumption
consumption necessary for life (shelter, food, water) - when disposable income is zero, this comes out of savings
marginal propensity to consume (MPC)
change in consumption (△C)/change in disposable income (△YD)
is the slope of the consumption function
change in consumption
MPC x change in disposable income
disposable income
national income - net taxes
national income
consumption + saving + taxes
marginal propensity to save (MPS)
change in saving (△S)/change in disposable income (△YD)
when taxes are constant, the marginal propensity to consume plus the marginal propensity to save must always equal
