To determine

The income of other entrepreneurs in the shoe shine business = $10,000

Joe's rent payment = $2,000 a year

Joe's revenue = $15,000 a year. He borrowed $1,000 at 20% interest rate to buy equipments.

At the end of one year, he was offered $500 (for business and equipment). Determine annual explicit costs, implicit costs and economic profit.

Explanation of Solution

Joe's annual explicit costs are given below:

  = Annual Rent payment + Borrowed money with interest rate= $2,000 + ($1,000 + $1,000×0.20)= $2,000 + $1,200= $3,200

Joe's annual implicit costs are given below:

  = Normal profit + Amount offered to Joe at the end of an year= $10,000 + $500= $10,500

Therefore, Joe's economic profit for the year is given below:

  = Total Revenue - Total Costs= $15,000 - (Implicit Costs + Explicit Costs)= $15,000 - ($10,500 + $3,200)= $15,000 - $13,700= $1,300

Economics Concept Introduction

Implicit Costs: The implicit cost is also called imputed cost or indirect cost. Implicit costs are the opportunity costs in the production, which means it measures the cost of giving up an input in order to use another input in the production process.

Explicit Costs: The explicit cost is a direct cost and known as out of pocket costs. It involves the expenditure done on the use of inputs in the production process by a firm.

  Economic Profit: Total Revenue – Total costs (= Explicit costs + Implicit Costs)

Use a game tree to illustrate why an aircraft manufacturer may price below the current marginal cost in the short run if it has a steep learning curve.   ​(Hint​: Show that learning by doing lowers its cost in the second​ period.) Part 2 Assume for simplicity the game tree is illustrated in the figure to the right. Pricing below marginal cost reduces profits but gives the incumbent a cost advantage over potential rivals.
