Question 27 A perfectly competitive industry is composed of 100 firms. Each firm has an identical short-run marginal cost function SMC = 5+10q (where q is the firm's level of output). If Q denotes industry output, what is the short-run market supply curve for output? a) Q = -50 + 10p if p > 5 and 0 if p 5 5 α Q = -5 + TOP p if p > 5 and 0 if p < 5 + α...

Consider an industry with 7 identical competitive firms. The production function of a representative firm is q = min{√x1, √x2}, where x1 and x2 are the inputs that the firm uses to produce output q. Suppose that the input prices are w1 = 4 and w2 = 3. The demand function is q^D(p) = 48 − p. Assume that firms cannot enter or exit the market. Find the equilibrium price and quantity. Compute the profit of each firm.

Problem 3 [24 marks] A competitive firm uses two inputs, capital (k) and labour (), to produce one output, (y). The price of capital, W, is S1 per unit and the price of labor, wi, is SI per unit. The firm operates in competitive markets for outputs and inputs, so takes the prices as given. The production function is f(k,l) 3k025/025. The maximum amount of output produced for a givern amount of inputs is y(k, l)...
2. Consider the following cost minimization problem. A firm minimizes total cost given by, TC = wL+rK subject to an output constraint as given by the production function, y=f(K,L)=8K05 +420S, where TC refers to total cost, L is labor input, K is capital input, r is the price of capital, w is the wage rate, and y is output. a. Derive the factor demand functions and the optimal cost function. The first order conditions and all the steps involved in...
