Answer:
Jessica should consume more of good A.
Explanation:
Jessica spends all her income on two goods, A and B.
The price of A is $5, and the price of B is $7.
At the current consumption bundle, the marginal utility of A is 10, and the marginal utility of B is 21.
The total utility is maximized when the ratio of marginal utility and price of the goods consumed is equal for all the goods in the bundle.
The ratio for Good A
= 
= 2
The ratio for good B
= 
= 3
Since the ratio is higher for good B, the consumer should shift from consumption of good B to good A until the ratio is equal for both the goods.
Answer:
Comparative Advantage
Explanation:
The assumption of Comparative Advantage theory is that there is no barrier.
It is explained in the model that if each country focuses on what it does best relatively then both countries together can produce more of each good/service using all their labor.
Then they can trade with each other and benefit. (To trade they must produce what the other need)
Answer:
Correct Answer:
C. Neither, both calculations give the same answer.
Explanation:
In any given business calculation that is expected to arrive at a particular solution, the solution obtained would always be the same irrespective of the method adopted. <em>For the example, the case of expected return of a portfolio in a business, the calculation would definitely give the same answer when two methods are adopted.</em>
Answer:
<em>Before setting your prices, it's wise to research industry standards- B.</em>
Answer: 16 units more than social optimum.
DWL = dead weight loss = (1/2)*(Q* - Q°) 12 =96
Explanation:
Q=1200 - 4P and Q=-240 + 2P
In a free market quantity demand =quantity supplied
1200 -4P = -240 +2P
P =240
Sub P
Q* = 240
Socially optimal quantity is
Marginal social benefit (MSC)= marginal social cost(MSC), including external damage =MEC
MPC= marginal private cost =inverse of supply function
MPC = (1/2)*Q + 120
MEC=12
MSC =(MPC +MEC) = (1/2)Q +120 +12
MSC= MPB where MPB is marginal private benefit = inverse of demand functn
MPB = 300 -(1/4)Q
(1/2)Q + 132 =300 - (1/4)Q
Q° = 224
Difference btw Q* & Q° = 16 units more than social optimum.
DWL = dead weight loss = (1/2)*(Q* - Q°) 12 =96
