Macroeconomics - Ch 10 Flashcards
45 degree line
reference line; C = DI; vertical distance between the 45 degree line and any point on the horizontal axis measures either consumption or disposable income
Consumption schedule/function
reflects the direct consumption - disposable income relationship
Saving schedule/function
saving = disposable income (DI) - consumption (C)
break-even income
income level at which households plan to consume their entire incomes (C = DI)
Average Propensity to Consume (APC)
fraction (%) of total income that is consumed; consumption divided by income
Average Propensity to Save (APS)
fraction of total income that is saved; saving divided by income
Marginal Propensity to Consume (MPC)
proportion/fraction of any change in income consumed; change in consumption divided by change in income
Marginal Propensity to Save (MPS)
fraction of any change in income saved; change in saving divided by change in income
wealth effect
households tend to increase their spending and reduce their saving; shifts the consumption schedule upward and the saving schedule downward
Paradox of thrift
possibility that a recession can be made worse when households become more thrifty and save in response to the downturn
Expected rate of return
expected profit as a percentage
Investment demand curve
amount of investment forthcoming at each real interest rate
Multiplier
a change in a component of total spending leads to a larger change in GDP; multiplier determines how much larger that change will be (ratio of a change in GDP to the initial change in spending);
