1) For each of the following changes, state what will happen to market equilibrium price and quantity in the short run.
(Use the demand curve)
a. Consumers expect that the price of the good will be higher in the future.
b. The price of a substitute good rises.
c. Consumer incomes fall, and the good is normal.
d. Consumer incomes fall, and the good is inferior.

f. The price of the product rises.

2) For each of the following changes, state what will happen to market equilibrium price and quantity in the short run.
(Use the supply curve)
a. The government requires pollution control filters that raise production costs.
b. Wages of workers in this industry fall.
c. There is an improvement in technology.
d. The price of the product falls.
e. Producers expect that the price of the product will fall in the future.

3) Demand is given by: QD = 6000 - 50P, Domestic supply is: QS = 25P, and Foreign producers can supply any quantity at a price of $40.
a. If foreign producers can sell in the domestic market, what is the equilibrium price? What is the equilibrium quantity? How much is sold by domestic and foreign producers, respectively?
b. Under domestic government pressure, foreign producers voluntarily agree to restrict their goods. What will happen to the price and quantity? What will happen to the amount that domestic producers supply? What will happen to revenues of domestic and foreign producers?

Analytical Questions for DISCUSSION Economics and Management
1) For each of the following changes, state what will happen to market equilibrium price and quantity in the short run.
(Use the demand curve)
a. Consumers expect that the price of the good will be higher in the future.

Solution:
When consumers expect that the price of the good will increase in the future, they will demand more goods now. So, the demand curve will shift to the right resulting in an increase in the market equilibrium price & increase in quantity in the short run. This is shown in the following graph.

In the above figure, D & S denotes the original demand & supply curves. P & Q are the market equilibrium price & quantity. Due to the consumers expectation about the future increase in price, the demand curve is shifted to D* which leads to an increase in the market equilibrium price & quantity as P* & Q*.

b. The price of a substitute good rises.

Solution:

If the price of a substitute good rises, then the demand for the good will increase & the demand curve will shift to the right. This results in higher market equilibrium price & quantity in the short run.

In the above figure, due to the increase in the price of the substitute good, the demand is increased & shifted to D*. Thus, a rightward shift in the demand curve leads to higher market equilibrium price (P*) & quantity (Q*).

c. Consumer incomes fall, and the good is normal.

Solution:

A fall in the consumer income leads to a decrease in the demand for normal good & the demand curve will shift to the left. This results in lower market equilibrium price & quantity. This impact is shown in the following figure.

Due to the decline in consumers income, the demand curve is shifted to the left as D* resulting in a decline in the market equilibrium price & quantity as ...

Operation Management: Economic Order Quantity and Delay During Lead Time

Please see the attached file for the fully formatted problems.

Problem #1- This is a production type EOQ problem, where the units produced each day go directly to inventory. Most production problems are treated as gradual delivery problems. Note that the carrying cost is 30% of the cost of making an individual DVD (.30 x 2.40).

The production rate of final assembly is 2,400 digital video discs (DVDs) per day. After DVDs are assembled, they go directly to finished-goods inventory. Customer demand averages 1,300 DVDs per day, or about 325,000 per year. It costs $700 to set up the assembly line for the DVDs, the cost per DVD is $2.30, and the carrying cost rate is 30 percent of product cost per year.

A. How many DVDs should be in production batch at final assembly?

B. What is the annual TSC at the EOQ?

Problem #2- This is a quantity discount EOQ problem.

E Office Supplies, Inc., sells discounted office supplies over the internet. One popular product sold is legal-size notepads, which are ordered by many law firms. E Office Supplies offers the following quantity discount structure, based on how many dozen notepads are ordered: 1-19 dozen, $21.95 per dozen; 20-99, $19.95 per dozen; 100-199, $18.95 per dozen; 200+, $17.95 per dozen. The law firm of Sanders, Taylor, Hernandez, Donahue and Smith (STHDS) would like to decide how many legal notepads to order using the EOQ model for quantity discounts. Its ordering cost is $35 per order, its anticipated need in the coming year is for 1,500 dozen notepads, and its annual carrying cost rate is 40 percent of acquisition cost.

A. How many dozen notepads should STHDS order each time?

B. What would be the resulting total inventory cost per year (ordering plus carrying plus materials)?

C. How many orders per year should be expected?

D. What is the expected maximum inventory level of notepads?

E. If STHDS has only enough storage space for 150 dozen notepads, how many should it order each time?

Problem #3 - This problem requires the determination of the order point. The distribution of demand during lead times (DDLT) is discrete.

An auto dealership has experienced the following historical demands during lead times for Ford half-ton pickup trucks:

Actual DDLT # of Occurrences Actual DDLT # of Occurrences
7 2 12 6
8 6 13 11
9 4 14 9
10 8 15 3
11 7 16 1

This data covers the dealerships past 57 orders to Ford. The replenishment lead time is five days to receive an order of trucks.
A. Compute the order point using a 90 percent service level
B. Compute the expected demand during lead time
C. What is the effective level of safety stock resulting from this order point?

Problem #4 - This problem requires determination of the order point when the DDLT is normally distributed.

If EDDLT = 65.5 unites, DDLT = 10.5 units, DDLT is normally distributed, and service level is 95 percent:

A. What is the order point?
B. What is the safety stock level?

Problem #5 - This problem requires the determination of the order point, etc. for demand that is normally distributed, however the lead time is relatively constant and the DDLT is estimated from the demand per period of time.

A part used to repair machines has a normally distributed monthly demand with a mean of 65.0 and a standard deviation of 5.2. If lead time is so predictable that it can be considered a constant 0.25 month and the service level is 90 percent.
A. What is the order point?
B. What is the safety stock level?
