His production function is:f (x1, x2) = (x1 – 1)0.25 x9-5.Assume the price of input 1 is r and the price of input 2 is w..(a) Write down an expression for the technical rate of substitution.(b) Find Juan's demand for inputs conditional on the quantity y of coffee Juanwants to produce.(c) Find Juan's cost function.(d) What is the supply function of Juan's firm?2. Show that the profit function is convex in (p, w).3. Find the profit function for the Cobb-Douglas production function f(¤1, 12) = Ax†' x"with A > 0, a1, ¤2 > 0 and a1 + a2 < 1.4. Verify Hotelling's Lemma for the Cobb-Douglas production function with a1+a2 < 1.5. Find the supply function and the input demand functions for the CES productionfunction:f(r1, F2) = A(ax{ + (1 – a)x2)8/e,%3Dwhere A > 0, B > 0, 0 < a < 1, and 0 + p< 1.6. Find the profit function for the CES production function.7. Verify Hotelling's Lemma for the CES production function with B < 1.

y = (x1 - 1)0.25x20.5 (a) MP1 = y/x1 = [0.25x20.5] / [(x1 - 1)0.75] MP2 = y/x2 = [0.5(x1 - 1)0.25]…

4) A firm faces a production function of twittle-twaps: Q(K,Lp,Ln) = 5*K(2/5)*LP(1/3)*LN(1/5) per hour, where capital (K), production labor (LP), and non-production labor (LN) are input factors used in production. The firm operates in a competitive market, where they are a price taker within the capital & labor markets and its own price (r = 40, wP = 25, wN = 50, P = 20). Answer the following.a. If capital and non-production labor are fixed at K = 32 and LN = 243, what is the general form MPLP and graph Q wrt to LP changing [you do not need to solve for LP yet].b. Is this production function decreasing, constant, or increasing returns to scale and why.c. Given the wage of production workers and the price of twittle-twaps, what is the optimal number of LP to employ to maximize profits and the quantity produced (VMPLP = wP).d.

Suppose that the total cost (in dollars) for a product is given by C(x)=1300+ 160 In(2x + 1) where x is the number of units produced. (a) Find the marginal cost MC function. MC = (b) Find the marginal cost when 160 units are produced. (Round your answer to the nearest cent.) $ Interpret your result. The profit from the next unit will be approximately this amount. This is the total cost of producing 160 units. ◇ This is the total profit from producing 160 units. ○ It will cost approximately this amount to make the next unit. (c) Total cost functions always increase because producing more items costs more. What then must be true of the marginal cost function? ○ MC ≥ 0 ○ MC > 0 ○ MC ≤ 0 ○ MC = 0 ○ MC <0 Does it apply in this problem? ○ Yes Ο ΝΟ
