Quiz 4-

1.  Suppose you are told that an economy's aggregate production is given by the equation

Y = 2K1/2L1/2

where Y is real GDP, K is units of capital, and L is units of labor. Initially K is constant and equal to 25 units. Furthermore, suppose you are told that the demand and supply of labor are given by the following equations where L is units of labor and W is the real wage.

Labor Demand: W = 18 - 2L

Labor Supply: W = 2 + 2L

a. Given the above information calculate for this economy the equilibrium quantity of labor, L; the equilibrium real wage, W; and the level of real GDP, Y. For full credit show your work.

L = ___________

W = __________

Y = __________

b. Given the above information, calculate the value of labor productivity. Show your work for full credit and indicate the units of measurement in your answer.

Suppose that the level of capital increases to 36 units.

c. Given this new level of capital, calculate for this economy the new equilibrium level of labor, L'; the equilibrium real wage, W'; and the level of real GDP, Y'. For full credit show your work.

d. Given the new level of capital, what is the value of labor productivity? Show your work for full credit.

e. In the space below draw a diagram representing labor market equilibrium and the aggregate production function for each level of capital. In your drawing identify L, L', W, W', Y, and Y'. In addition illustrate and label labor productivity in your drawing. Label your diagram carefully and completely.

2.  Consider the loanable funds market for a closed economy that is initially operating with a balanced government budget (that is, government saving is initially equal to zero).

a. Holding everything else constant, the government increases its spending. For each of the following variables determine whether the variable increases, decreases, remains constant, or is indeterminate given this change in government spending.

i. The interest rate _________________________________________________________

ii. The level of private investment ____________________________________________

iii. The level of private savings _______________________________________________

iv. The level of government savings ___________________________________________

b. Return to the initial situation. Holding everything else constant, this economy opens to trade and imports more than it exports. For each of the variables determine whether the variable increases, decreases, remains constant, or is indeterminate given this change.

i. The interest rate _________________________________________________________

ii. The level of private investment ____________________________________________

iii. The level of private savings _______________________________________________

iv. The level of government savings ___________________________________________

c. Return to the initial situation. Holding everything else constant, this economy simultaneously opens to trade and exports more than it imports while the government of this economy increases its spending. For each of the variables determine whether the variable increases, decreases, remains constant, or is indeterminate given these changes.

i. The interest rate _________________________________________________________

ii. The level of private investment ____________________________________________

iii. The level of private savings _______________________________________________

iv. The level of government savings ___________________________________________
