(Answers for all given questions (b-f) to compare for notes)

The following Table describes the labor market for the whole economy of a given country. Assume perfect and full information is available to every participant in this economy, factors of production are perfectly mobile, prices and wages are perfectly flexible, and perfect competition prevails in all markets.

Units of labor (1)	Opportunity cost of a worker in terms of units output = real wage required by an additional worker (2)	Real value of Output per additional worker Maximum real wage a producer is willing to pay for an additional worker (3)
8	1	9
10	2	8
12	3	7
16	4	6
18	5	5
20	6	4
22	7	3

a) Carefully draw for yourself the demand and supply curves of labor on a diagram and find the equilibrium real wage and the equilibrium level of employment. Don't submit the diagram.

To each level of employment corresponds a level of real GDP given in the following table.

Production Function Schedule

Level of Employment	Aggregate quantity supplied = real GDP
10	10
12	40
14	65
16	85
18	100
20	105

b) Find the full employment real GDP, aggregate quantity supplied AQS , and nominal wage for each of the following price levels P = 1, 2 ,3, 4. Does the equilibrium levels of employment and AQS change as the price level changes?

Is the long run aggregate supply curve downward or upward sloping or is it a vertical line?

Suppose that the velocity of money is constant V = 5 and the money supply is M^s = 80.

c) For each one of the following levels P = 1, 2, 3, 4 and 5, find the aggregate quantity demanded AQD according to the quantity theory. (Plot for yourself the corresponding aggregate demand curve on the same diagram as the long run aggregate supply curve. You need to submit the schedule of the Aggregate demand curve). What is the equilibrium price level, the equilibrium real GDP, equilibrium aggregate quantity AQS and the equilibrium aggregate quantity demanded? What is the equilibrium nominal wage?

Suppose now that V = 5 does not change but the money supply decreases to M s = 60.

d) What is the new equilibrium price, and the new equilibrium real GDP? What is the new equilibrium nominal wage? What happened to the equilibrium price level P and the equilibrium nominal wage?

e) comparing your answers to c) and d) what happened to the equilibrium real GDP, and employment?

f) Are your answers to the previous two questions consistent with the observed data on the money supply, the price level, nominal wages real GDP and unemployment during the 1929-1933 depression? (Use the relevant diagrams in chapter 20 to justify your answers)
