AS stuff Flashcards
(11 cards)
What is the natural rate hypothesis
- Theory proposed by Milton Friedman that there is a natural rate of unemployment that the economy tends to in the long run
What happens in long run in NRH
- The economy self corrects and output returns to its potential
What does NRH mean for policy
- Any demand side policy will be inflationary
What type of expectations in NRH
Adaptive
What does adaptive expectations mean in SR when there is a demand side policy
- Ad shifts out and price expectationd do not change which means an increase in output and prices
What happens in the LR with adaptive expectations
Price expectations adapt upwards in the long run and AS will shift left, thus output returns to normal level but with inflation now
What are the policy implications of rational expectations
- When demand side policy is enacted, AS shifts inward as soon as policy is enacted and price rises and output stays the same
Derive the AS curve with money illusion
- The demand curve shifts to the right reflecting an increase in prices
- Labour supply curve shifts up less than the demand curve as workers are suffering money illusion
- This means equilibirum employment increases from N1 to N2
How is the steepness of the AS curve impacted by the degree of money illusion
- If there is little money illusion, the AS curve is steeper
So in terms of impact on employment, what does money illusion do
The more money illusion, the higher employment from a demand shift
What do some economists think about the slope of the supply curve
- Upward sloping in the SR
- Vertical in the LR
