A firm in a purely competitive industry has a typical cost structure. The normal rate of profit in the economy is 5 percent. This firm is earning $5.50 on every $50 invested by its founders. a. What is its percentage rate of return? 11 percent.
b. Is the firm earning an economic profit? Yes If so, how large? 6 percent.
c. Will this industry see entry or exit? Entry
d. What will be the rate of return earned by firms in this industry once the industry reaches long-run equilibrium?

The answers are given below

Explanation:

a. What is its percentage rate of return?

From the question, we are told that the firm is earning $5.50 on every $50 invested by its founders. The percentage of return will now be:

= $5.50/$50 × 100%

= 0.11 × 100%

= 11%

b. Is the firm earning an economic profit? If so, how large?

The economic profit will be the difference that exists between the percentage of return which is 11% and the normal rate of profit which is 5%. This will be:

= 11% - 5%

= 6%

The firm is earning economic profit of 6%.

c. Will this industry see entry or exit?

There will be entry into the industry. This is because the percentage of return which is 11% is greater than the normal rate of profit which is 5%.

d. What will be the rate of return earned by firms in this industry once the industry reaches long-run equilibrium?

The rate of return earned by firms in this industry once the industry reaches long-run equilibrium will be 5% which is the normal rate of profit in the economy.

When you divide you number actually gets bigger.

You flip the last number in the question and then turn it in to a multiplication problem and then solve!!
