Consider the production function of widget: Q = 28K0.8 L0.4, where Q is units of output per month. K is hours of capital and L is hours of labour. Capital can be rented at $60 per hour and labour can be hired at $22 per hour. What is the maximum level of output for a monthly production budget of $20000? Answer: ______________ units.

10. Do the following production functions have increasing, decreasing, or constant returns to scale? Show work.(i) Q = 3K+2L (ii) Q = 6KL

2. A firm has a production function given by the following table: Units of Labor 1 2 3 4 5 K=1 3 8 12 15 17 K=2 10 15 19 22 24 K=3 16 21 25 28 30 K=4 20 25 28 30 31 (1) Suppose that K is fixed at 2. Does this production function exhibit diminishing marginal returns? (ii) Does this production function exhibit constant returns to scale for all values of K and L?

1. Assume a daily production function for a firm is Q= min(3L, 4K) a, If L = 100 and K = 100 what quantity is produced? Explain why. b. What would be the cost-minimizing labor and capital combination for this firm to produce Q = 1200? (show your work) Labor = Capital = At this level of production from part b (Q-1200), if the wage rate is: w- $30 and the rental rate of capital is: r= $100, what is the total cost of production? (show your calculations) C.

13. Suppose you have a production technology given by f(x1, x2) = min{2x₁, x2} and you are producing at the point where x₁ = 10 and x₂ = 20. (a) Explain in words what we mean (generally) by the ‘marginal product' of an input in production. (b) For the production technology in this question and the initial point x₁ = 10 and x2 = 20, what is the marginal product of a small increase in input 1? (c) Suppose input 2 increases and you are now at the initial point x₁ = 10 and x2 = 30. Relative to your answer in part (b), does the marginal product of input 1 decrease, increase, or stay constant? Explain briefly.

5. Selpats produces pens with the production function f(k, l) = 200vkl. The price of capital is wk = 40 and the price of labor is wL = 10. (i) Determine the optimal input bundle for producing y pens in the long run and find the long-run cost function. (ii) Determine the optimal input bundle for producing y = 10,000 pens in the long run. (iii) Now suppose that capital is fixed at k = 25 in the short run. Find the short-run total cost function and the short-run marginal cost function. Explain the relationship between the short-run and long-run marginal costs when y = 10,000. (iv) Suppose that the price of output is p. Which value of y maximizes short-run profit? р.

Suppose a pizza parlor has the following production costs: $5.00 in labor per pizza, $3.00 in ingredients per pizza, $0.20 in electricity per pizza, $1,500 in restaurant rent per month, and $250 in insurance per month. Assume the pizza parlor produces 1,000 pizzas per month. What is the variable cost of production (per month)? The variable cost of production is $ (Enter your response as an integer.) What is the fixed cost of production (per month)? The fixed cost of production is $ ☐. (Enter your response as an integer.)
