Answer:

87%

Explanation:

The four firm concentration ratio calculates the concentration ratio of the 4 largest firms in an industry. This is done by adding the market share of the 4 largest firms

0.27 + 0.26 + 0.22 + 0.12 = 0.87

Assume that the market is perfectly competitive. If the cost function for John's Shoe Repair is �(�) = 100 + 10� − �) + 3 4 �4,
kirill [66]

Answer:

Explanation:

C(q) = 100+10q-q^2+(1/3)q^3

To find the firm marginal cost function:

Take the derivative with respect to q

MC = 10 - 2q + q^2

Assuming that the market price is p , then the profit maximising condition is:

MR = MC

p = 10 - 2q + q^2

The short-run supply curve is the marginal cost curve that lies above the average variable cost.

The average variable cost is:

AVC =VC/Q

AVC = (10q-q^2+(1/3)q^3)/Q

AVC = 10 - q + (1/3)*q^2

So, the short-run supply curve is:

SRS = 10 - 2q + q^2 if p > 10 - q + (1/3)*q^2

Which of the following pair of journal entries correctly records the current month's activity where the company had $21,030 in t
Lelechka [254]

Answer:

----------------------    -   -------------------------------

Factory Payroll         21030

             Cash                        21030

----------------------    -    -------------------------------

Goods in process     16200

Factory Overhead     4830

       Factory Payroll               21030

----------------------    -    -------------------------------

Explanation: The payment of the total labor factory costs must be recorded, we debit the "Factory payroll" cost account and credit the "cash" account as they were paid in cash.

Then we must allocate these costs to the production process, therefore we debit the "goods in process" account for the amount of <u>direct labor</u> consumed, and "factory overhead" for the amount of <u>indirect labor </u>consumed, and finally credit the account " Factory payroll " for the total.

ella [17]

Answer:

Holding period yield is 114.97%

effective yield is 8.72%

Explanation:

holding period yield=(Price at call-initial price+coupon payments)/initial price

                                =($970-$935)+(13*$80)/$935

                                 =($35+$1040 )/$935

                                 =$1075/$935

                                  =114.97%

The effective yield is the yield to call which can be computed using the excel rate formula:

=rate(nper,pmt,-pv,fv)

nper is the number of payments before the call which is 13

pmt is the periodic payment by bond which is $1000*8%=$80

pv is the current market price of $935

fv is the bond price at end of 13 years at $970

=rate(13,80,-935,970)

rate=8.72%
