Explanation:

Part 1

As a store manager, Jean Clark has to take decision regarding how many cases of strawberries should be purchased. Let Ai represents course of actions regarding how many cases to be purchased, where i = 10, 11, 12, or 13 cases.

Jean has identified state of nature or circumstances for the demand of the strawberries per cases in future. Let Sj represents various demand in future, where i = 10, 11, 12, and 13 cases.

Part 2:

$Price_{purchase\, per \,case} = \$3\\Price_{selling\, per \,case} = \$8\\ Value_{salvage} = \$0\\$

Payoff in terms of profit or loss function is determined as follows:

$Payoff = Profit_{ per case} \times cases_{ sold }-Price_{purchase} \times cases_{ unsold}\\Payoff = \$5 \times cases_{ sold} -\ $3 \times cases_{unsold}$

The payoff table is obtained using the above formulas and is attached.

Part 3:

Maximin Decision Rule:

This approach selects the alternative which maximizes the minimum payoff among all events.

Minimum payoffs of purchasing 10, 11, 12, 13 cases are $50, $47, $44, and $41 respectively.

Maximum payoff among the alternative minimum payoffs is $50 for the alternative of purchasing 10 cases.

As the alternative of purchasing maximizes the minimum payoff among all events, Jane should select alternative of purchasing 10 cases of strawberries for tomorrow.

Part 4:

Equal Likelihood Principle

This principle is based on a simple philosophy that if there is uncertainty about various events, then treat them as equally probable to occur, that is, each state of nature or chance event is assigned an equal probability. It is also known as equal probabilities criterion. In this assumption, the expected value (EV) or average payoff for each course of action or strategy is determined and the strategy with the highest mean value is adopted.

$EV_{10 cases} = [(0.5 \times \$50) + (0.5 \times \$50) + (0.5 \times \$50) + (0.5\times \$50) = \$50\\EV_{11 cases} = [(0.5 \times \$47) + (0.5 \times \$55) + (0.5\times \$55) + (0.5 \times \$55) = \$53$

Similarly,

EV of purchasing 12 cases = $54

EV of purchasing 13 cases = $53

Maximum EV = maximize [$50, $53, $54, $53] = $54

According to the equal likelihood Principle, the alternative of purchasing 12 cases gives maximum expected value, thus Jane should purchase 12 cases of strawberries.

Part 5:

Bayes’ Decision rule

This rule considers the prior probabilities for the state of natures and selects the alternative with the maximum expected payoff. Expected payoff is calculated as sum of product of probabilities and payoff of each alternative.

Expected payoff pd purchasing 10 cases are as follows:

$EP _{10 cases} = 0.2 \times \$ 50 + 0.4 \times \$ 50 +0.3 \times \$ 50 + 0.1 \times \$ 50 = \$50\\EP_{11 cases} = (0.2 \times \$47) + (0.4 \times \$55) + (0.3 \times \$55) + (0.1 \times \$55) = \$53.4$

EP (12 cases) = $53.6

EP (13 cases) = $51.4

The maximum EP is $53.6 for the alternative of purchasing 12 cases, thus Jane should purchase 12 cases of strawberries.

Part 6:

To determine the cost Jane should determine Expected value of perfect information (EVPI), as follows:

First determine Expected value with perfect information (EVwPI) as follows:

Maximum payoff when demand is exactly 10 cases is $50, Expected payoff = 0.2 x 50 = $10

Maximum payoff when demand is exactly 11 cases is $55, Expected payoff = 0.4 x 55 = $22

Maximum payoff when demand is exactly 12 cases is $60, Expected payoff = 0.3 x 60 = $18

Maximum payoff when demand is exactly 13 cases is $65, Expected payoff = 0.1 x 65 = $6.5

EVwPI = $10 + $22 + $18 + $6.5 = $56.5

Expected value without perfect information (EVwoPI) = Maximum expected value by Baye’s rule = $53.6

EVPI = EVwPI – EVwoPI = $56.5 – $53.5 = $3

Jean should spend $3 to get more information about how many cases of strawberries she might be able to sell tomorrow.

The quantity demanded of cereal increased from 1,350 to 1,700 when the price of milk decreased from $2.05 to $1.65. What is the

STALIN [3.7K]

Answer:

-1.33

Explanation:

Cross price elasticity of demand measures the responsiveness of quantity demanded of good A to changes in price of good B.

If cross price elasticity of demand is positive, it means that the goods are -substitute goods.

Substitute goods are goods that can be used in place of another good.

If the cross-price elasticity is negative, it means that the goods are complementary goods.

Complementary goods are goods that are consumed together

Cross Price elasticity of demand = percentage change in quantity demanded of good A / percentage change in price of good B

percentage change in quantity demanded of good = (1700/ 1350) - 1 = 0.259

percentage change in price = (1.65 / 2.05) - 1 = -0.195

0.259 / -0.195 = -1.33

The present value interest factor for an annuity with an interest rate of 8 percent per year over 20 years is ____.

lianna [129]

The present value factor of an annuity that will mature in 20 years at an interest rate of 8% is <u>9.8181474.</u>

<h3>What is the present value interest factor?</h3>

It can be found by using the present value of an annuity formula of:

= Amount x ( 1 - ( 1 + rate) ^ - number of periods) / Rate

As there is no amount, solving gives:

= ( 1 - ( 1 + 8%) ⁻²⁰) / 8%

= 9.8181474

In conclusion, it is 9.8181474.

A municipal dealer places an order for $100,000 of new issue G.O. bonds, M '45 with the syndicate manager. The bonds will be pla

professor190 [17]

Answer:

The options for the question is:

A. pre-sale net

B. syndicate group net

C. designated net

D. member takedown

Explanation:

The answer is D. member takedown

The priority accorded to the order by the manager will be treated as member takedown orders, and if there is sufficient interest in the issue, the order would not be filled because of the other orders with higher priority being filled first.

When an order is placed with the syndicate by a member for an "accumulation account" that is being managed by that member, it is strange in that the bonds are not being sold to the general public.

The syndicate member must disclose to the manager when the order is placed; the manager will then disclose any of these orders that have been filled to the other syndicate members when the account is closed; and the manager will fill these orders last- meaning they get priority after pre-sales, group, and designated orders.
