Suppose a firm has access to two production processes with the following marginal cost curves: MC₁ = 2Q₁ and MC₂ = 3Q₂

If it wants to produce 30 units of output, how much should it produce with each process?

Output for a simple production process is given by Q = 2KL, where K denotes capital and L denotes labor. The price of capital is $25 per unit and capital is fixed at 5 units in the short run. The price of labor is $5 per unit. What is the variable cost of producing 80 units of output? Explain how you calculated your answer.

7. Use MC1 = MC2

2Q1 = 3Q2

Q1 = 1.5Q2

And since Q1 + Q2 = 30

we have 1.5Q2 + Q2 = 30

Q2 = 30/2.5 = 12 and Q1 = 18

Hence Q1 = 18 and Q2 = 12

8. Production function is Q = 2KL, r = $25 per unit, w = $25 per unit and K = 5 units in the short run.

When Q = 80, we have 80 = 2*5*L which gives L = 80/10 = 8 units

Variable cost = wL = 25*8 = $200

The graph shows the marginal cost and average total cost curves for a perfectly competitive firm. The horizontal axis measures output in thousands of units per year, from 0 to 50, increasing by 10. The vertical axis measures the revenue and cost in dollars per unit, from 0 to $25, increasing by $5. The graph shows two U-shaped curves, labeled MC and ATC. The minimum point of the ATC curve corresponds to an output of 30 and a cost of...

Assume that the marginal abatement cost curves (MACs) are linear and that the firm currently faces a standard imposed at the optimal level of pollution. Suppose a new technology can be adopted at zero cost, which causes the MAC to swing downwards. Also, assume that if the firm adopts the technology, the regulator automatically adjusts the standard to its new optimal level. Under what conditions will the firm adopt the new technology?
