In the short run a firm can produce 11 units of output by employing 2 units (hours) of labour and 15 units of output employing 3 units of labour. Suppose the hourly wage rate is $10. What is the marginal cost of producing the 14th unit of output? Clearly show all steps of your work.

Expert Solution

Total cost of producing 11 units = Labor hours × Hourly rate

= 2 × 10

= $20

Total cost of producing 15 units = Labor hours × Hourly rate

= 3 × 10

= $30

Marginal cost of producing 15th unit = Difference in total cost / Difference in units

= (30 – 20) / (15 – 11)

= 10 / 4

= 2.5

Total cost of producing 14 units = Total cost of producing 15 units - Marginal cost of producing 15th unit

= 30 – 2.5

= 27.5

Marginal cost of producing 14th unit = (TC of 14 units – TC of 11 units) / Difference in units

= (27.5 – 20) / (14 – 11)

= 7.5 / 3

= 2.5

Answer: $2.5

Note: TC means total cost.

Assume that in the short run a firm is producing 100 units of output, has average total costs of $100, and average fixed costs of $20. The firm's total variable cost at this output level is A) $120. B) $80. C) $8,000. D) $12,000.

A firm in a perfectly competitive market will produce no output in the short run if the price is below $20 but will produce if the price is above $20.

A firm in a perfectly competitive market will produce no output in the short run if the price is below $20 but will produce if the price is above $20. The smallest quantity they will produce in the short run is 6. Firms will earn 0 economic profit if the price is $447.5 and its profit maximizing quantity is 21 at that price. The firm’s fixed cost is $6615. Assume the good can be produced in continuous quantities.Draw a picture...

(1) Will the firm produce in the short-run at the price? Of $41? Explain why?

Now assume that product price falls to $41.(1) Will the firm produce in the short-run at the price? Of $41? Explain why?(2) If yes, how many units? Is this output profit-maximizing or loss minimizing? What would be profit/loss? (show all your calculations). Show the firm equilibrium on a separate graph using average cost curves.(c). Assume price drops further to $32.(1) Will this firm produce or not? Explain if not, why not? Determine profit/losses and show your answer graphically using average/marginal...
