Answer:

26%

Explanation:

An investor can design a risky portfolio based on two stocks, A and B. Stock A has an expected return of 16% and a standard deviation of return of 25%. Stock B has an expected return of 11% and a standard deviation of return of 10%. The correlation coefficient between the returns of A and B is .4. The risk-free rate of return is 9%.

The proportion of the optimal risky portfolio that should be invested in stock B is approximately

= (0.11 - 0.09)(0.25^2) - (0.16 - 0.09)(0.1)(0.25)(0.4) / (0.11 - 0.09)(0.25^2) + (0.16 - 0.09)(0.1)(0.25) - (0.11 - 0.09+0.16 - 0.09)(0.1)(0.25)(0.4)

= 0.00055 / 0.0021 = 26%

Answer: 26%

Explanation:

Given the following ;

Expected rate of return A=16%= 0.16

Standard deviation A = 25% = 0.25

Expected rate of return B=11%=0.11

Standard deviation B = 13% = 0.13

Risk free rate = 9% = 0.09

Optimal risky portfolio that should be invested in stock B

(0.11 - 0.09)(0.25^2) - (0.16 - 0.09)(0.1)(0.25)(0.4) / (0.11 - 0.09)(0.25^2) + (0.16 - 0.09)(0.1)(0.25) - (0.11 - 0.09+0.16 - 0.09)(0.1)(0.25)(0.4)

= 0.00055 / 0.0021 = 0.2619

= 26%

When a central bank increases bank reserves by $1, the money supply rises by more than $1. The amount of extra money created whe
zvonat [6]

Answer:

ii) in a fractional-reserve banking system, each dollar of reserves can support more than one dollar of deposits, thereby increasing the money supply by more than $1.

Explanation:

In a  fractional-reserve banking system, banks only keep a fraction of total deposits on hand. They will usually only keep the amount required by the Fed, which is called the required reserve ratio. Banks will lend the rest of the money to customers, since they make money by borrowing from customers and lending it at higher rates.

E.g. you deposit $1,000 in the bank. The bank is required to keep 10% in reserves, but lends $900 to another client. That client will spend the money and purchase something. The seller of that good or service then deposits the money into his/her bank. That second bank will then separate $90 as reserves and lend $81 to a different client which will again purchase something, and the cycle goes on...
