The long-run supply curve for a product is horizontal with ATC = 200. Market demand is defined as P = 1,000 − 4 Q. The market is

competitive and is in long-run equilibrium with 50 firms in the industry. If demand increases to P = 1,240 − 4 Q, how many firms will be in the industry at the new long-run equilibrium?

Answer:

65 firms will be in the industry at the new long run equilibrium

Explanation:

in the long run the P=ATC

quantity before the change is

200 = 1000-4Q

4Q = 800

Q= 200

each firm output = Q/number of firms = 200 / 50

q = 4

new quantity is

200 = 1240-4Q

4Q = 1040

Q = 260

number of firms=new Q/q

=260/4 = 65

the number of firms is 65 in the long run.

Determine whether the following statement is true or false, and explain your reasoning:
Triss [41]

Answer:

The statement is true

Explanation:

As a fact, I agree that with large sample sizes, even the small differences between the null value and the observed point estimate can be statistically significant.

To put it differently, any differences between the null value and the observed point estimate will be material and/or significant if the samples are large in shape and form.

It's also established that point estimate get more clearer and understandable, and the difference between the mean and the null value can be easily singled out if the sample size is bigger.

Suffix to say, however, while the difference may connote a statistical importance, the practical implication notwithstanding, will be looked and studied on a different set of rules and procedures, beyond the statistical relevance.

xeze [42]

Answer:

1.64 years

2.27 years

3.13 years

Explanation:

Discounted payback calculates the amount of time it takes to recover the amount invested in a project from it cumulative discounted cash flows

Present value of cash flow in year 1 = 4300 / 1.13 = 3805.31

Amount recovered in year 1  = -5800 + 3805.31 = -1994.69

Present value of cash flow in year 2 = 4000 / (1.13^2) = 3132.59

Amount recovered in year 2 =-1994.69 + 3132.59 = 1137.90

Payback period = 1 + 1994.69/3132.59 = 1.64 years

B

Present value of cash flow in year 1 = 4300 / 1.13 = 3805.31

Amount recovered in year 1  = -7900 + 3805.31 = -4094.69

Present value of cash flow in year 2 = 4000 / (1.13^2) = 3132.59

Amount recovered in year 2  = -4094.69 + 3132.59 = -962.10

Present value of cash flow in year 3 = 5200 / (1.13^3) = 3603.86

Amount recovered in year 3  = -962.10 + 3603.86 = 2641.76

Payback period = 2 years + -962.10 / 3603.86 = 2.27 years

C

Present value of cash flow in year 1 = 4300 / 1.13 = 3805.31

Amount recovered in year 1  = -10900 + 3805.31 = -7094.69

Present value of cash flow in year 2 = 4000 / (1.13^2) = 3132.59

Amount recovered in year 2  = -7094.69 + 3132.59 = -3962.10

Present value of cash flow in year 3 = 5200 / (1.13^3) = 3603.86

Amount recovered in year 3  = -3962.10 + 3603.86 = -358.24

Present value in year 4 =  4400 / (1.13^4) = 2698.60

Amount recovered in year 4  = -358.24 + 2698.60 = 2340.36

Payback period = 3 years + 358.24 + 2698.60 = 3.13 years
