19. Maurice is graduating at the end of summer school and is delighted that he has gotten four job offers. All four job offers are for similar work and Maurice's only criterion for accepting a job is that it happens to be in St. Paul since he has fallen in love with all that the Twin Cities offers. However, Maurice's parents view this decision from a somewhat different perspective: they want Maurice to take the job that has the highest salary for next year (this single year perspective is meant to simplify the analysis). So, here are Maurice's job offers and he needs your help in evaluating the choices.

Job Offer

Annual Salary

Job in New York City

$100,000

Job in Chicago

$80,000

Job in San Francisco

$120,000

Job in St. Paul

$70,000

Maurice in his Economics class learned the importance of looking at real purchasing power so he first tells his parents that these job offers are a bit more complicated than just their nominal amounts since the cost of living differs quite a bit in these four communities. Suppose that Maurice collects data on the CPI for these four communities and finds the following data.

City

CPI for this year

New York City

100

Chicago

80

San Francisco

115

St. Paul

65

Given this data, rank these job offers from highest real salary to lowest real salary. Given your ranking, Maurice's tastes and preferences, and his parents tastes and preferences is St. Paul an option for Maurice?

a. San Francisco, St. Paul, and New York and Chicago (last two are equivalent); no, St. Paul will not satisfy Maurice's parents

b. St. Paul, San Francisco, and New York and Chicago (last two are equivalent); yes, St. Paul is an option

c. New York and Chicago are equivalent, San Francisco, and St. Paul; no, St. Paul is not offering a competitive real salary

d. New York and Chicago are equivalent; San Francisco, and St. Paul; yes, Maurice's parents will fuss but ultimately let their son have his way since these four offers are very close to one another in terms of real purchasing power

Use the information below to answer the next two (2) questions.

Consider an economy where the demand for loanable funds from businesses is given by the following equation where Q is the quantity of loanable funds and r is the interest rate:

Demand for loanable funds from businesses: Q = 10,000 - 500r

Suppose that the supply of loanable funds from households (private savings) is given by the following equation where Q is the quantity of loanable funds and r is the interest rate:

Supply of loanable funds from households: Q = 500r - 1000

In both the demand and supply for loanable funds equations the interest rate is expressed as a percentage (thus, if the interest rate is 5%, then the r in the equation would be 5). Initially assume that this economy is a closed economy and that the government in this economy has a balanced budget.

27. Given this information and holding everything else constant, if the government decides to run a surplus of $1000 we know with certainty that:

a. The equilibrium interest rate in the loanable funds market will be greater than 11% and that the level of private investment will be equal to 5000.

b. The equilibrium interest rate in the loanable funds market will be equal to 10% and that the level of private investment will be equal to 5000.

c. The equilibrium interest rate in the loanable funds market will be less than 11% and that the level of private saving will be less than 4000.

d. The equilibrium interest rate in the loanable funds market will be less than 11% and that the level of private investment will be less than 4000.

28. Given the initial information, if the government decides to run a deficit of $1000 we know, holding everything else constant, that:

a. Private investment will be crowded out by $500.

b. Private investment will increase by $500 from its original level.

c. Private investment will be unaffected by the government running a surplus.

d. The decrease in private investment that occurs is due to an increase in household consumption.

29. Suppose an economy is at full employment. Holding everything else constant, when the government runs a surplus this results in:

a. A decrease in private saving.

b. An increase in private saving.

c. A decrease in consumption by households.

d. Answers (a) and (c) are both correct.
