. Apple uses labour and machines to produce iPhones according to the production function y = LM, where L is the number of units of labour used and M is the number of machines. The cost of labour is w = 4 per unit and the cost of using a machine is wM = 16. Apple faces a fixed cost of F = 25 for renting its factory. Given these input prices, Apple chooses how much labour and machines to employ in order to minimize the cost of producing any given amount of iPhones y. Apple is therefore solving a cost-minimization problem. (a) If Apple is cost-minimizing, how many workers will it use for each machine? That is, find the number of workers per machine that Apple will employ. (Hint: setup the tangency condition.) (b) Continuing to assume that Apple produces any given number of iPhones y in the cheapest way possible, use the equation defining the number of workers per machine from part (a) and Apple's production function to find expressions for the cost-minimizing choices of labour and machines as functions of output produced y. (c) Now use your answers to part (b) to derive Apple's total cost for producing iPhones as a function of the number of units produced y.

Suppose that the price of labor (the wage rate) is $100 a day and that the rental price of capital is $50 a day. Currently the Jedie Weapons Corporation is using ten units of capital and five units of labor to produce 500 lightsabers a day. Each lightsaber sells for $2. At the current input use levels, the marginal product of capital is 40 lightsabers per day and the marginal product of labor is 60 lightsabers a day. Is the firm making an economic profit at its current levels of operation? 2. Could the firm increase its profits at the current level of output by adjusting its use of labor and capital? If so, how should input use be adjusted?

The following table shows the capital and labor requirements for 10 different levels of production. Assuming that the price of labor (PL) is $8 per unit and the price of capital (PK) is $6 per unit, compute and graph total cost, marginal cost, and average cost for the firm.

Production Functions and Cost Functions in the short run and in the long run Consider the production function Q=KL. The firm needs to produce 64 units of output. The price of capital is R=$16 and the price of labor is W=$4 a. In the short run, the firm's capital is fixed at K=16. How much labor will it use? What is its short run total cost? Hint: Solve it for a generic Q and plug Q=64 only at the very end b. Find the firm's short run total cost, average total cost, and marginal cost curves. Hint: If you are trying to find cost curves, Q is unknown. c. Set up a Lagrangian to find the firm's optimal inputs in.

Emma sells hot chocolate outside of Yankees baseball games. They have two inputs in the production of hot chocolate: (hot chocolate mix (x1, measured in kg) and labour (x2, measured in hours. The production function for hot chocolate (in liters) is: f (x1 , x2) = (x1)1/3(x2)1/3 A) Does this firm have constant, increasing or decreasing returns to scale? The cost of hot chocolate mix is w1, and the cost of labour is w2. If Emma produces "y" liters of hot chocolate the cheapest way possible, then B) How many kilograms of hot chocolate mix would they use? C) How many hours of labour? D) What is the cost function of producing this much hot chocolate?
Question # 1: Majeda wrote the following answer on her microeconomics examination: “Virtually every production function exhibit diminishing returns to scale because my professor said that all inputs have diminishing marginal productivities. So, when all inputs are doubled, output must be less than double." How would you grade Majeda's answer? Question # 2: Suppose a firm had a production function with linear isoquants, implying that its two inputs were perfect substitutes for each other. What would determine the firm's expansion path in this case? For the opposite case of a fixed-portions production function, what would the firm's expansion path be? Question # 3: Suppose that a firm's production function is q = 30√L. In the short run, where there are fixed costs of $2,200, and labor is the variable input whose cost is $6,300 per units. What is the total cost of producing 20 units of output?
