Answer: D. Since Hiro’s economic profit is negative, he would be better off if he didn’t operate the consulting business and taught economics instead.
Step-by-step explanation:
Economic Cost is calculated by taking into account all costs, both Implicit and Explicit. Implicit Costs are also known as Opportunity costs and are referred to as the income you could be earning if you were doing the alternative.
Hiro's Economic Cost can hence be calculated by,
Economic Cost = Implicit costs + Explicit Costs
= (50,000 + 100) + 57,000
= $107,000
Subtracting that from his Revenue per year gives,
= 100,000 - 107,000
= -$7,000
Hiro is experiencing an Economic Loss by operating his business and would be better off Teaching Economics at the small local college.
