chap 14 Flashcards
recession
period of falling incomes and rising unemployment
depression
a severe recession
model of aggregate demand and supply
explains short-term fluctuations in economic activity around its long run trend
aggregate demand
shows relationship b/w aggregate (overall) price lvl and total quantity of aggregate output demanded by houses, business, and govs
basically quantity g/s demanded at each price lvl
interest rate effect
when price lvl dec, demand for money dec…..demand curve shifts left
dec IR for money supply, inc investment expenditures
- since investment is in aggregate demand, inc g/s is demanded
real exchange rate effect
when canadian price lvls dec, canadian goods are cheaper than foreign goods
(bcs foreign exchange rate is constant)
inc CAD exports, dec imports of foreign g/s
- NX inc
greater amount CAD g/s demanded at lower CAD price lvls
factors that cause the aggregate demand curve to shift left
- changes in consumption and investment
- if consumers pessimistic abt economic future, purchase fewer capital goods - changes in gov purchases
- if G dec, aggregate d curve shifts left - changes in net exports (if dec, curve shifts left)
- exports dec if US/world business cycle downturns of value of CAD dec
- imports inc if value of CAD inc compared to world
aggregate supply curve
says quantity of g/s that firms produce and sell at price lvls
vertical line bcs price lvl doesn’t impact real GDP
curve is at natural rate of output
natural rate of output
production of g/s in long run when unemployment is at natural rate
supply curve is vertical bcs it depends on SUPPLIES OF LABOUR and FOP (not impacted by changing prices)
long-term AS curve
curve may shift from changes in labour, capital, and natural resources
short-term AS curve (SRAS)
price lvl raises quantity of g/s supplied (curve up)
curve up only occurs in short turn, bcs corrections are made to adjust to prices over time
sticky wage theory
says output deviates from natural rate when price lvl deviates what’s expected
quantity of output supplied = natural rate of output + a (actual price lvl - expected price lvl)
a - # that determines how much output responds to changes in price lvl
why SRAS might shift
- changes in labour
- dec labour causes shift left - changes in capital
- changes in tech
- changes in natural resources
- changes in expected price lvl
- inc in expected future price lvls causes higher fixed nominal wage
- causes SRAS shift left
long-run equilibrium`
point of SRAS equilibrium on LRAS curve
2 causes of economic fluctations
dec in:
- aggregate demand
- aggregate supply
