4. Consider the following production function Q = LK with MPL=K and MPK=L (Hint: labor and capital are NOT perfect substitutes) a. Calculate the marginal rate of technical substitution of labor for capital. b. Indicate if the MRTS is increasing, decreasing or constant. c. Find three points in the isoquant associated to the production of Q=500. Show the graph and also a table indicating the values of L and K used in at least three points in the isoquant.

3. The production function is given by q=20KL with MPL=20K & MPK=20L. The cost of labor w=10 and the cost of capital r=20. a) The firm wants to produce 4,000 units of output. In the short run the plant’s capital is fixed at k=5. Find the amount of labor it must employ to produce 4,000 units of output. Calculate the short run total cost. Show the isocost and isoquant associated with that point (label it as point “A”). Scale: x-axis: 1 square=2 units; y-axis: 1 square=2 units. b) In the long run the firm wants to produce 4,000 units of output. Find the optimal combination of inputs. Show and label the isocost and isoquant associated with that point. Label the optimal combination of inputs as point “B”. Scale: x-axis: 1 square=2 units; y-axis: 1 square=2 units.

5. Suppose this market is a monopoly. a) The monopolist faces the same demand curve P = 300- 5Q and initially faces a constant marginal cost MC = 30. Calculate the profit- maximizing monopoly quantity and compute the monopolist’s total revenue at the optimal price. b) Suppose that the monopolist’s marginal cost increases to MC = 90. Compute the monopolist’s total revenue at the optimal price.

Shrimp, SA is a small business that sells farm-raised shrimp. The market for farm-raised shrimp is perfectly competitive. The short- run total cost of production is STC( Q) = 0.2Q2  + 12Q  + 600, where Q is the number of pounds of shrimp sold. The prevailing market price is $ 40 per box of shrimp. a) How many pounds should Shrimp, SA sell to maximize profit? b) Is Shrimp, SA having profits or losses? Calculate. c) If a firm is facing loses, when would you recommend them to shut down? Explain under which circumstances you would suggest the owner to shut down.
