Download Inflationary and Recessionary Gaps

Inflationary v. Recessionary Gaps
Classical v. Keynesian View
“ If Society values full employment as
an economic goal, is a capitalist
economy inherently capable of
achieving that goal without intervention
on the part of the government?”
Economic Statistics Rules of Thumb
Good  2-3% Inflation Bad
Bad  3-4% Growth (RGDP) Good
Good  4-5% Unemployment Bad

Long Run Equilibrium at Full Employment
AD = SRAS = LRAS
Actual GDP (where AD intersects SRAS) = Potential GDP
(FE/ LRAS)

Classical view of a Recessionary Gap
1. Economy is producing < FE; Actual GDP < Potential GDP
2. # of unemployed > # of job openings
3. W rate is bid down, C of P↓ , shifts SRAS0 to SRAS1
4. PL ? GDP? U?
The economy self adjusts! Equilibrium is restored!

Keynesian view of a Recessionary Gap
1. Economy is producing < FE; Actual GDP < Potential GDP
2. # of unemployed > # of job openings
The economy needs help from the government!
3. Increase G, Increase TP, decrease T, or increase MS to increase AD.
4. PL ? GDP? U?
Equilibrium is restored but what happens to inflation?

Classical view of an Inflationary Gap
1. Economy is producing beyond FE; Actual GDP > Potential GDP
2. # of unemployed < # of job openings
3. W rate is bid up, C of P ↑, shifts SRAS0 to SRAS1
