Answer to Problem 5P

Total explicit cost is $220,000: Accounting profit with low income is -$20,000 and with high profit is $180,000.

Explanation of Solution

Current earning per worker is $60,000. She would prefer to become an entrepreneur unless she  earns an accounting profit of at least $60,000. As an entrepreneur, she is planning to open a small grocery store. She has an annual cost of $150,000 for labor, $40,000 for rent and $30,000 for equipments.

There is a one-half probability that the revenue equals to $200,000 (low revenue) and one-half probability that revenue equals to $400,000.

Total explicit cost can be calculated as follows.

Total explicit cost=(Labor cost)+(Rent)+(Equipment cost)=(150,000+40,000+30,000)=220,000

Total explicit cost is $220,000.

Accounting profit with low revenue can be calculated as follows.

Accounting profit=Low revenueCost=200,000220,000=20,000

Accounting profit with low income is -$20.000.

Accounting profit with low revenue can be calculated as follows.

Accounting profit=High revenueCost=400,000220,000=180,000

Accounting profit with high income is $180.000.

Answer to Problem 5P

Expected average revenue is $300,000: Accounting profit is $80,000 and Economic profit is $20,000.

Explanation of Solution

Expected average revenue can be calculated as follows

Expected revenue=((ProbabilityHigh income×High income)+(ProbabilityLow income×Low income))=(0.5×400,000)+(0.5×200,000)=200,000+100,000=300,000

Expected average revenue is $300,000.

Expected accounting profit can be calculated as follows.

Expected accounting profit=Expected revenueExplicit cost=300,000220,000=80,000

Expected accounting profit is $80,000.

Expected economic profit can be calculated as follows.

Expected accounting profit=Expected revenueExplicit costWage=300,000220,00060,000=20,000

Expected economic profit is $20,000. The person would quit the job since there is a positive economic profit.

Answer to Problem 5P

Accounting profit after tax is $135,000: Expected profit is $57,500 and  -$2,500.

Explanation of Solution

There is an accounting loss with the low income. Thus, the accounting profit with the low income does not change.

Accounting profit with high income after tax can be calculated as follows.

Accounting profit after tax=Accountign profitHigh income(1Tax rate)=180,000(10.25)=180,000(0.75)=135,000

Accounting profit after tax is $135,000.

Expected accounting profit after tax can be calculated as follows.

Expected accounting profit=((ProbabilityLow income×Expected profitLow income)+(ProbabilityHigh income×Expected profitHigh income))=(0.5(20,000)+0.5(135,000))=10,000+67,500=57,500

Expected accounting profit is $57,500.

Expected economic profit after tax can be calculated as follows.

Expected economic profit=Expected accounting profitWage=57,50060,000=2,500

Expected economic profit is -$2,500. Since the expected economic profit is negative, the person would not quit the job.

Sub part (d):

To determine

Whether the individual is indifferent or not between Accounting profit after tax and current earnings.

Sub part (d):

Expert Solution
Check Mark

Explanation of Solution

The accounting profit after tax in case of average revenue is $60,000, which is equal to the current earnings. Therefore, she is indifferent about her decision to quit the job or not. So, some people would prefer to go for entrepreneurship and other will stay as workers.

2. Another issue facing millennials is the growing income and wealth inequality. We will use our model to understand the implications of this issue. A. Begin from the baseline preferences and endowments. Assume Xavier is wealthier than Yuri. Xavier has an endowment of 1100 pounds for each period (E1=E2=1100). Yuri has an endowment of only 900 pounds in each period (E1=E2=900). Note that each period's market supply is unchanged (1100 + 900 = 1000 + 1000 = = 2000). Determine the equilibrium interest rate. r = % B. Begin from the baseline preferences and endowments. Assume Yuri is wealthier than Xavier.
