Suppose the large number of bike accidents in a small town results in new legislation that requires all citizens of the town to

wear specialized bike helmets when riding. These new helmets reduce the probability of head trauma by 25% during a bike accident.While the new helmets (Increase/Decrease) the probability of a serious head injury resulting from a bike accident, they also incentivize cyclists to ride (less/more) safely, which could (Increase/Decrease) the number of bike accidents and thus head injuries to cyclists.

Answer:

<h2>The sequential pattern of answers would be <u>decrease,less</u> and <u>increase</u>.</h2>

Explanation:

  • In the first case, the legalization of new helmets would actually reduce the probability of serious head injuries from cycle accidents as it might probably better and well-equipped safety and preventive structure or materials.
  • However, as people or riders start using more of these new helmets,they might become less cautious about safe riding resulting in more number of cycle accidents in the streets.
  • Hence,increase in careless and rash riding might result in more number of cycle accidents thereby,leading to higher chances of head injuries.

Here are returns and standard deviations for four investments. Return (%) Standard Deviation (%) Treasury bills 4.5 0 Stock P 8.
Jlenok [28]

Answer:

a. Standard deviation of the portfolio = 7.00%

b(i) Standard deviation of the portfolio = 30.00%

b(ii) Standard deviation of the portfolio = 4.00%

b(iii) Standard deviation of the portfolio = 21.40%

Explanation:

Note: This question is not complete. The complete question is therefore provided before answering the question as follows:

Here are returns and standard deviations for four investments.

                                  Return (%)           Standard Deviation (%)

Treasury bills                4.5                                    0

Stock P                          8.0                                   14

Stock Q                        17.0                                  34

Stock R                       21.5                                    26

Calculate the standard deviations of the following portfolios.

a. 50% in Treasury bills, 50% in stock P. (Enter your answer as a percent rounded to 2 decimal places.)

b. 50% each in Q and R, assuming the shares have:

i. perfect positive correlation

ii. perfect negative correlation

iii. no correlation

(Do not round intermediate calculations. Enter your answers as a percent rounded to 2 decimal places.)

The explanation to the answer is now provided as follows:

a. Calculate the standard deviations of 50% in Treasury bills, 50% in stock P. (Enter your answer as a percent rounded to 2 decimal places.)

Since there is no correlation between Treasury bills and stocks, it therefore implies that the correlation coefficient between the Treasury bills and stock P is zero.

The standard deviation between the Treasury bills and stock P can be calculated by first estimating the variance of their returns using the following formula:

Portfolio return variance = (WT^2 * SDT^2) + (WP^2 * SDP^2) + (2 * WT * SDT * WP * SDP * CFtp) ......................... (1)

Where;

WT = Weight of Stock Treasury bills = 50%

WP = Weight of Stock P = 50%

SDT = Standard deviation of Treasury bills = 0

SDP = Standard deviation of stock P = 14%

CFtp = The correlation coefficient between Treasury bills and stock P = 0.45

Substituting all the values into equation (1), we have:

Portfolio return variance = (50%^2 * 0^2) + (50%^2 * 14%^2) + (2 * 50% * 0 * 50% * 14% * 0) = 0.49%

Standard deviation of the portfolio = (Portfolio return variance)^(1/2) = (0.49%)^(1/2) = (0.49)^0.5 = 7.00%

b. 50% each in Q and R

To calculated the standard deviation 50% each in Q and R, we first estimate the variance using the following formula:

Portfolio return variance = (WQ^2 * SDQ^2) + (WR^2 * SDR^2) + (2 * WQ * SDQ * WR * SDR * CFqr) ......................... (2)

Where;

WQ = Weight of Stock Q = 50%

WR = Weight of Stock R = 50%

SDQ = Standard deviation of stock Q = 34%

SDR = Standard deviation of stock R = 26%

b(i). assuming the shares have perfect positive correlation

This implies that:

CFqr = The correlation coefficient between stocks Q and = 1

Substituting all the values into equation (2), we have:

Portfolio return variance = (50%^2 * 34%^2) + (50%^2 * 26%^2) + (2 * 50% * 34% * 50% * 26% * 1) = 9.00%

Standard deviation of the portfolio = (Portfolio return variance)^(1/2) = (9.00%)^(1/2) = (9.00%)^0.5 = 30.00%

b(ii). assuming the shares have perfect negative correlation

This implies that:

CFqr = The correlation coefficient between stocks Q and = -1

Substituting all the values into equation (2), we have:

Portfolio return variance = (50%^2 * 34%^2) + (50%^2 * 26%^2) + (2 * 50% * 34% * 50% * 26% * (-1)) = 0.16%

Standard deviation of the portfolio = (Portfolio return variance)^(1/2) = (0.16%)^(1/2) = (0.16%)^0.5 = 4.00%

b(iii). assuming the shares have no correlation

This implies that:

CFqr = The correlation coefficient between stocks Q and = 0

Substituting all the values into equation (2), we have:

Portfolio return variance = (50%^2 * 34%^2) + (50%^2 * 26%^2) + (2 * 50% * 34% * 50% * 26% * 0) = 4.58%

Standard deviation of the portfolio = (Portfolio return variance)^(1/2) = (4.58%)^(1/2) = (4.58%)^0.5 = 21.40%

On January 1, 2020, Korsak, Inc. established a stock appreciation rights plan for its executives. It entitled them to receive ca
kykrilka [37]

Answer:

$570,000

Explanation:

Missing question: <em>"On December 31, 2022,50,000 SARs are exercised by executives. What amount of compensation expense should Korsak recognize for the year ended December 31, 2020"</em>

Amount of compensation expense = [(33-20)*120,000*3/4] - [(30-20)*120,000*2/4]

Amount of compensation expense = [13*120,000*3/4] - [10*120,000*2/4]

Amount of compensation expense = 1,170,000 - 600,000

Amount of compensation expense = $570,000

So. the amount of compensation expense that Korsak should recognize for the year ended December 31, 2020 is $570,000.

A commercial bank buys a $50,000 government security from a securities dealer. the bank pays the dealer by increasing the dealer
stealth61 [152]

Answer:

Increased by $50,000

Explanation:

When the Federal Reserve or a any private bank buys government securities from another private company or investor, they "create" money in the same way as a loan creates money.

Therefore, when the commercial bank bought government securities worth $50,000 from a private securities dealer, the money supply increased by $50,000.

In previous years, Cox Transport reacquired 2 million treasury shares at $22 per share and, later, 1 million treasury shares at
Hoochie [10]

Answer:

24 million shares  ; $16 million

Explanation:

The computation of the weightage number of treasury shares are shown below:

             Number of shares       Price       Total

                   2                              $22         $44 million

                   1                               $28         $28 million

Total           3                                               $72 million

So, the weighted average number of shares would be

= $72 ÷ 3 = 24 million shares

Now the journal entry would be

Cash A/c Dr $64 million                  (2 million treasury shares × $32)

          To Paid in capital - share repurchase A/c $16 million

          To Treasury stock $48 million    (24 million treasury shares × $2)

(Being the treasury shares are sold)
