Inflationary and Recessionary Gaps
With the Classical / Monetarist / Neo-Classical Model long run
equilibrium is as follows:
LRAS
Price Level
Pf
AD
Yf
RGDP
Short run equilibrium may differ from Long Run
 macroeconomic SR: period of time when prices of final g&s
change, but factor prices do not – so final prices are in
equilibrium, but factor prices are not
 macroeconomic LR: period of time when factor prices do
adjust to final prices, AS=AD at full employment of fop in the
LR
 SR equilibrium may be to the R of LRAS  Inflationary gap
 SR equilibrium may be to the L of LRAS  Deflationary gap
Real GDP
LR real GDP

Time
Year 2: recessionary gap
 actual output is less than real GDP
 unemployment of resources
LRAS
price level
SRAS
AD
Y2
Yf
RGDP
Y2 to Yf is the recessionary gap
 the economy is operating at less than full employment in the
SR
 also called unemployment equilibrium as Y2 to Yf represents
unemployed fop
Year 3 : full employment
Price level
LRAS
SRAS
AD
Yf
RGDP
Year 4: inflationary gap
LRAS
SRAS
AD
Yf Y4
RGDP
Yf to Y4 is an inflationary gap
 the economy is operating at greater than full employment in
the SR
o fop are over-employed – workers are working overtime,
capital is employed in double shifts
