The daily cost of producing pizza in New Haven is C(Q) = 4Q + (Q2/40); the marginal cost is MC = 4 + (Q/20). There are no avoida

ble fixed costs. What is the market supply function if there are 10 firms making pizza? If 20 firms are making pizza? What is the market supply curve under free entry? [HINT: As the first step, find the AC and show that AC is at its minimum when Q = 0.]

Answer:

q_{10} = 200P - 800

q_{20} = 400P - 1600

Explanation:

let the supply function be : P = MC

P = 4 + Q/20

therefore Q = 20P - 80 ( supply function )

For 10 firms

Q = 10( 20P - 80 ) = 200P - 800

for 20 firms

Q = 20(20P - 80 ) = 400P - 1600

next determine market supply curve under free entry

AC = 4 + Q/40

Hence ; when Q = 0 , AC = 4   and this is for unlimited number of firms

Sam wants to be a teacher. He has been imitating the behavior, mannerism, and dressing style of teachers at his school. What gro
likoan [24]

Answer:

  • <u>  models  </u>

<u />

Explanation:

The teachers that Sam imitates constitute <u>  models  </u> for him.

One of the first learning modes that every human use is the imitation. A baby can learn by direct experience (if he touches a metallic surface in winter the baby learns it is cold) or by imitation: when the baby sees the mom talking the baby learns to move the lips. The mother is baby's first model and the baby learns by imitating her.

When we grow up, we have many models: relatives, friends, peers, teachers, and virutally any person with whom we are in contact.

Imitating continues during all the life and teachers are very important models.

Specially, when the teacher is a good example and arouses admiration, the students will trend to imitate them. Particularly, in the case of Sam who wants to be a teacher: probably Sam has had some excellent teachers whom he admires and made him to want to follow their steps, which is why he imitates them. They are a good model to follow.

Qd = 600 – 4p – 0.03M – 12 Pr + 5T + 6Pe + 1.5N Where Qd = quantity demanded for commodity A; P = price of commodity A; M = cons
NISA [10]

Answer:

A. It implies a fixed 600 units of commodity A will always be demanded without being influenced by any factor that determine the quantity demanded for good ‘A'.

B. 4. Yes.  The reason is that the price of good A is indirectly proportional to the quantity demanded for good ‘A'.

C. It implies that the quantity demanded for good ‘A' decreases by 0.03 as the consumer's income increases by $1. It is an inferior good.

d. Goods A and B are complements since the negative sign implies that the quantity demanded for good ‘A' decreases as the  price of related commodity (good ‘B') (Pr) increases. The interpretation of the the slope parameter for the price of good B is that the quantity demanded for good ‘A' decreases by 12 units as the price of related commodity (good ‘B') (Pr) increases by $1.

E. Yes, the algebraic signs on the slope parameters for T, Pe, and N are correct. The reason is that quantity demanded for good ‘A' will increase as each of T, Pe, and N increases.

f. Quantity demanded for good ‘A' is 2,374.

Explanation:

A. Interpret the intercept parameter in the generalized demand function.

In the generalized demand function, 600 represents the Interpret the intercept parameter.

This implies that 600 units is a fixed units of commodity A is demanded and this is not affected by any factors that determines the quantity demanded for good ‘A'.

Therefore, it implies 600 units of commodity A will always be demanded.

B. What is the value of the slope parameter for the price of good A? Does it have the correct algebraic sign? Why? 4. Yes since indirectly proportional.

From the generalized demand function, the value of the slope parameter for the price of good A is 4.

Yes, it has a the correct algebraic sign which is a minus sign.

The reason is that the price of good 'A' is indirectly proportional to the quantity demanded for good ‘A'.

C. Interpret the slope parameter for income for income. Is good ‘A' normal or inferior? Explain. 0.03. Since Em less than 1 it is normal goods

The slope parameter for income (M) is -0.03. This implies that the quantity demanded for good ‘A' decreases by 0.03 as the consumer's income increases by $1.

It is an inferior good because the quantity demanded for good ‘A' decreases as the consumer's income increases.

d. Are goods A and B substitutes or complements? Why? Interpret the slope parameter for the price of good B.

Since the slope parameter for price of related commodity (good ‘B') (Pr) is negative (i.e. –12), this implies that goods A and B are complements.

The negative sign implies that the quantity demanded for good ‘A' decreases as the  price of related commodity (good ‘B') (Pr) increases.

The interpretation of the the slope parameter for the price of good B is that the quantity demanded for good ‘A' decreases by 12 units as the price of related commodity (good ‘B') (Pr) increases by $1.

E. Are the algebraic signs on the slope parameters for T, Pe, and N correct? Explain

Yes, the algebraic signs on the slope parameters for T, Pe, and N are correct.

The reason is that quantity demanded for good ‘A' will increase as each of T, Pe, and N increases. This implies that there is a positive relationship between the quantity demanded for good ‘A' and each of T, Pe, and N.

f. Calculated the quantity demanded for good ‘A' when P = $15, M = $25000, Pr = $40, T = 6.5, Pe = $5.25 and N = 2000?

Given;

Qd = 600 – 4p – 0.03M – 12 Pr + 5T + 6Pe + 1.5N ............... (1)

Each of the value is then substituted into equation (1) and we then calculate as follows:

Qd = 600 - (4 * 15) - (0.03 * 25000) - (12 * 40) + (5 * 6.5) + (6 * 5.25) + (1.5 * 2000)

Qd = 2,374

A college graduate who is searching for his first job illustrates the concept of cyclical unemployment. frictional unemployment.
zvonat [6]

Answer: frictional unemployment

Explanation:

Frictional unemployment is also referred to as search unemployment. Frictional unemployment is the time that people spend between jobs when they are looking for a job or in cases whereby they are transferring from one job and looking for another job.

The turnover in the labor market is actually a reason for being frictionally unemployed. Also, when someone graduates from college, the person also begins to look for work. The person is frictionally unemployed during the time that he or she is looking for job.
