Document Summary

Questions: what is the difference between a change in the curve and a shift in the curve, they are the same thing. Steering wheels would be a cost in the production of a car: complements are like two different products that are automatically produced at the same time. Textbook: a point where opposing forces balance. Mark rush: a situation in which there is no automatic tendency to change. The equilibrium price is the only point where there is no shortage or surplus. What happens to supply and demand: demand increased so the demand curve shifts to the right (from d to d"). The new equilibrium price is higher and so is the equilibrium quantity: on a graph, the shift looks like this: Four step procedure to solving supply and demand questions: Example suppose the price of cotton used to make jeans rises. What happens to the supply and demand: draw a graph.

THE PARTS IN BOLD ARE MARKED AS THE PARTS NEEDED HELP. ATTACHED IS THE ENTIRE ASSIGNMENT FOR ONLY PURPOSE THAT ALL INFORMATION IS INCLUDED. IF YOU COULD PLEASE ONLY HELP WITH PART 15 AND 17. PE=? QE=? AND PART 17 SITUATIONS OCCURING SIMULTANEOUSLY! THANK YOU!

Consider the market for new, single-family homes in New Orleans. The general demand function for new housing in New Orleans is estimated to be

Qd =15-2P+0.05M+0.10R

where Qd is the monthly quantity demanded, P is the price per square foot, M is average monthly income in New Orleans, and R is the average monthly rent for a three-bedroom apartment in New Orleans. Qd is measured in units of 1,000 square feet per month.

New housing in New Orleans is a(n) __________________ (normal, inferior) good. How can you tell from the general demand function?

New housing and three-bedroom apartments are _________________ (substitutes, comple- ments) in New Orleans. How can you tell from the general demand function?

If average monthly income is $1,500 and the monthly rental rate for three-bedroom apart- ments is $700, then the demand function for new housing in New Orleans is

Qd = _____________________________________.

Graph the demand curve for new housing in New Orleans on the axes provided below. Label

the demand curve D0.

What happens to demand when the following changes occur?

a. b. c. d. e.

The price of the commodity rises.
Income decreases and the commodity is normal. Income decreases and the commodity is inferior.

The price of a complement good increases. The price of a substitute good decreases.

The general supply function for new housing in New Orleans is estimated to be Qs =96+2P-10PL -4PK

where P is the price per square foot of new housing in New Orleans, PL is the average hourly wage rate for construction workers, and PK is the price of capital (as measured by the average rate of interest paid on loans to home builders). Qs is measured in units of 1,000 square feet per month.

Does it make sense for PL and PK to have negative coefficients in the general supply func- tion? Explain why or why not.

If the average hourly wage rate for construction workers is $10 per hour and the average rate of interest on loans to builders is 9 percent (i.e., PK = 9), then the supply function for new housing is

Qs = ______________________.

Graph the supply curve for new housing in the graph below. Label supply S0.

Other things remaining the same, what would happen to the supply of a particular commodity if the following changes occur?

The price of the commodity increases.

Government regulators outlaw the use of a technology that enables the good to be

produced at a significantly lower cost.

The prices of inputs used to produce the commodity decrease.

The price of a commodity that is a substitute in production increases.

Managers expect the price of the good to fall in the near future.

As the cost of capital rises, firms in the industry stop purchasing plant and equip-

ment, which allows depreciation to diminish the productive capacity in the indus- try.

Solve mathematically for equilibrium price and quantity. Show your work:

PE = $__________ per square foot.
QE = __________ square feet per month (in 1,000s).

Do your supply and demand curves intersect at PE and QE found in question 8 above? Should they?

In equilibrium found in question 8, compute total consumer, producer, and social surpluses:

CS = $____________ PS = $____________ SS = $____________

13. Suppose New Orleans suffers a serious recession that causes average monthly income to fall from $1,500 to $1,100 per month. If other things remain the same, the demand for new hous- ing in New Orleans is now:

Qd = _______________________. Plot this new demand curve in the figure below. Label it D'.

Suppose that because of the recession in New Orleans, the wage rate for construction workers falls to $8 per hour. If other things remain the same, the supply of new housing in New Orle- ans is now:

Qs = _______________________.
Plot this new supply curve in the figure. Label the new supply curve S'.

After income falls to $1,100 and wages fall to $8, new equilibrium price and quantity are PE = $__________ per square foot
QE = __________ square feet per month (in 1,000s)

Determine the effect upon equilibrium price and quantity sold if the following events occur in a particular market:

The price of a substitute good (in consumption) decreases.

Consumersâ income increases and the good is inferior.

Government regulators decide to outlaw a cost-reducing technological

process in order to protect the environment.

The price of a complement good (in production) increases.

The price of inputs used to produce the good decrease.

Consumers expect that the price of the good will fall in the near future.

It is widely publicized that consumption of the good is helpful in prevent-

ing cancer.

The price of a substitute good (in production) decreases.

17. Suppose that a pair of events from problem 15 occur simultaneously. For each of the pairs of events indicated below, perform a qualitative analysis to predict the direction of change in either the equilibrium price or the equilibrium quantity. Explain why the change in one of these two variables is indeterminate.

Both a and h in problem 15 occur simultaneously.

Both b and e in problem 15 occur simultaneously.

Both d and g in problem 15 occur simultaneously.

Both f and c in problem 15 occur simultaneously.

1. Other things remaining the same, a left shift in the supply curve will lead to:

A. a decrease in the equilibrium price and the equilibrium quantity.

B. an increase in the equilibrium price and the equilibrium quantity.

C. an increase in the equilibrium price and a decrease in the equilibrium quantity.

D. a decrease in the equilibrium price and an increase in the equilibrium quantity.

A. leads to a fall in the price of the other good.

B. leads to a left shift in the demand for the other good.

C. leads to a right shift in the demand for the other good.

D. doesn't affect the demand for the other good.

5. Which of the following was an effect of the price ceiling placed on gasoline in the U.S. in the 1970s?

A. Gas stations ran out of gas as the quantity of gas demanded exceeded the quantity supplied.

B. Car owners started buying luxury cars that were less fuel-efficient as the price of gas was very low.

C. Those who valued gas the most were able to buy gas under the price ceiling.

D. The inventory of unsold gas increased and gas stations incurred losses.

6. Willingness to accept is:

A. the highest price that a producer is willing to receive to sell an extra unit of a good.

B. always higher than the marginal cost of production.

C. always lower than the marginal cost of production.

D. the lowest price that a producer is willing to receive to sell an extra unit of a good.

7. Assume that the economy is in a recession and consumers are expecting a fall in their income levels. This will cause a(n):

A. right shift in the market demand for all goods.

B. left shift in the market demand for all goods.

C. increase in the total quantity demanded of all goods.

D. decrease in the total quantity demanded of all goods.

B. An increase in the supply of coffee due to better weather

C. A higher tax on the sale of tea, a substitute for coffee

D. A fall in the manufacturing cost of coffee
