Question

Again, consider the following table for a profit-max, perfectly competitive firm that produces using only labor and capital. You can calculate the values for the table cells with letters in them (though you won't enter all these values on the exam).


Calculate the value for Cell D, marginal cost between 24 and 25 units of labor employed, carefully following all numeric instructions.

Labor Used Quantity Produced Labor Cost Capital Cost Total Cost Marginal Cost 24 1200 $2400 $3000 A --- 25 1800 $2500 $3300 B D 26 2200 $2600 $3600 C E

Explanation / Answer

Calculate Total Cost When 24 units of labor are used (Cell A) -

Total Cost = Labor cost when 24 units of labor are used + Capital cost when 24 units of labor are used

Total Cost = $2,400 + $3,000 = $5,400

Calculate Total Cost When 25 units of labor are used (Cell B) -

Total Cost = Labor cost when 25 units of labor are used + Capital cost when 25 units of labor are used

Total Cost = $2,500 + $3,300 = $5,800

Calculate Marginal Cost between 24 and 25 units of labor employed (Cell D) -

Marginal Cost = Total Cost when 25 units of labor are used - Total Cost when 24 units of labor are used

Marginal Cost = $5,800 - $5,400 = $400

Thus, the Marginal Cost between 24 and 25 units of labor employed (Cell D) is $400.
