Investor A has an initial wealth of $100 and a utility function of the form: U(w) = log(w) where w is her wealth at any time. In

vestment Z offers her a return of −18% or +20% with equal probability. i. What is her expected utility if she invests nothing in Investment Z? ii. What is her expected utility if she invests entirely in Investment Z? iii. What proportion a of her wealth should she invest in Investment Z to maximize her expected utility? What is her expected utility if she invests this proportion in Investment Z?

With this initial investment of 100, the investors utility if she invests nothing is 2. If she invests entirely her utility is 2.00432

From the available question, these are the the solutions from option (i) to (iii)

i.) We have utility defined as

U(w) = log w

w = 100

Utility=log(100)

= 2

ii) If she invests entirely in Z, utility:

return*probability\\

-18% x 50% =  -9%

20% x 50% = 10%

-9% + 10% = 1%

w = 100 + 1

= 101

Utility = log(101)

= 2.00432

This is her utility if she invests entirely in Z.

iii) This investor has these two choices:

  • invest in z
  • leave resources idle

If she invests in z she gets a 1% increase. Therefore her wealth increases or is maximum when she invests in Z.

Her utility if she invests this proportion in Z is the same as what was solved in (ii) above.

John borrows $10,000 for 10 years at an effective interest rate of 10%. He can repay the loan using the amortization method with
Ierofanga [76]

Answer:

The balance in the Sinking Fund immediately after repayment of the loan will be $2,133.19

Explanation:

Hi, John will pay the loan by paying the yearly interest and the rest is going to go to the sinking fund, so, if he has $1,627.45 and the annual interest of the loan are $1,000, he will be depositing $627.45 into the sinking fund for ten years. Therefore, the future value of the annual deposits of the sinking can be found by using the following formula.

FutureValue=\frac{A((1+r)^{n} -1)}{r}

Where:

A = equal annual savings into the sinking fund (that is $627.45)

r = effective rate of the sinking fund (14%)

n = 10 years

Everything should look like this.

FutureValue=\frac{627.45((1+0.14)^{10} -1)}{0.14}

Future Value=12,133.19

Now, this is the balance after 10 years, but remember that John has to pay the loan, which is $10,000 (not $11,000 because John pays the interest of the loan and then deposits the balance into the sinking fund). Therefore, the balance after repaying the loan is $12,133.19 - $10,000 = $2,133.19.

Best of luck.

Ede4ka [16]

Answer:

TRUE.

Explanation:

One key for sport organizations to use market segmentation effectively involves integrating the strategy with a DBM or CRM system to pinpoint which segments can be contacted. Both DBM and CRM systems can give an organization very valid and reliable information about their customers which then managers can use to form patterns and analyse trends and buying habits of the customers. This information can be easily used for effective targeting. Managers can easily know which segments they should target and how sales can be increased in that particular segment. What offers should be sent to that specific segment.

Arturiano [62]

Answer:

c) Annual set up cost= $9878.04

Explanation:

<em>Economic batch quantity (EBQ) is also known as economic production run, It is the optimum production run that a manufacturer should operate to minimize set up cost and carrying cost. </em>

<em>Carrying cost is the cost of keeping inventory while set up cost is cost of getting machines ready for production</em>

Annual inventory cost = = Set up cost per  run×   Annul demand / EBQ

<em>Annual demand / the economic production run(EBQ)</em>

It is calculated as follows:

Economic batch quantity =√2× Co× D / Ch(1-D/P)

Where ,

D - annual demand - 62,500

Ch -holding cost per unit per annum - $11.50

Co- set up cost - $320

Production rate  = 1650 units per day  × 250 days =412,500 units

<em>Economic batch quantity</em>

= √(2× 320× 62,500) / (11.50× (1- 62500/412500) )

=2024.69 units

<em>Annual set up cost</em>

= Set up cost per run ×   Annul demand / EBQ

= $320×  62,500/2024.69

Annual set up cost= $9878.04
