CH14 - Inflation and disinflation Flashcards
What are the macroeconomic forces that cause the general level of nominal wages to change? (2)
- Output gap
- Expectations of future inflation
What type of pressure on wages does an inflationary gap put?
Upward pressure
(Y > Y*)
What is NAIRU? (U*)
Non-accelerating inflation rate of unemployment
At equilibrium, (GDP = Y*), what is said about the unemployment rate?
It’s NAIRU
Why is the NAIRU not 0?
Because even when Y = Y*, there is some amount of frictional and structural unemployment
What is the relationship between GDP and unemlployment
Negative
If GDP is less than Y, unemployment rate will be more than U
What pressure does the expectation of some specific inflation rate do?
Pressure for nominal wages to rise by that specific rate
As long as people expect prices to rise, their behavior will put _______ pressure on nominal wages.
upward
(even when there is no real inflation)
What is the total effect on wages equation?
Output-gap effect + Expectational effect
Changes in wages and other factor prices lead to what?
Shifts the in AS curve
What are deflationary forces?
The combined effect of the output-gap and expectational effect is to reduce wages, therefore shifting down the AS
What is the actual inflation equation?
Output-gap inflation + Expected inflation + Supply-shock inflation
What is constant inflation?
When inflation stays at the same rate for several years
What happens if inflation and monetary policy are unchanged for several years?
expected rate of inflation = actual rate of inflation
What happens if there are no supply shocks and expected inflation = actual inflation?
real GDP = potential GDP
What does a constant inflation require from the AD and AS curve?
To both shift upward equally
With constant inflation, why is the demand curve shifting up?
Because the central bank increases the money supply
With constant inflation, why is the supply curve shifting up?
Because of the wage increase
What is validating the expectations?
When a central bank increases the money supply at a rate that the expectations of inflation end up being correct
What is the assumption regarding AS and AD shocks in the analysis of the macro model?
They do not influence the level of potential output Y*
