- The Mini-Case "Economies of Scale at Google describes economies of scale for Google Cloud Storage. The cost function for this service is well-approximated by K C(q)-F+cq where C is total cost, F is fixed cost, c is a constant and q is output. What is marginal cost for this cost function? What are the average fixed cost, average variable cost, and average cost? Over what range of output does Google have economies of scale? The marginal cost function (MC) is The average fixed cost function (AFC) is AFC- The average variable cost function (AVC) is AVC- MC-C The average cost function (AC) is AC- (Property format your expressions using the tools in the palette.

Suppose also that in the short-run, the firm uses 8 machines in the production process. (a) Show that the firm’s short-run average cost (SRAC) is SRACK=8 = (16/Q)+ 4√? (b) Draw the SRAC curve(c) By solving the first order conditions that the global minimum of production is 4(d) Show that the firm’s long-run average cost (LRAC) is 12. Hint: Start by obtaining the firm’s long-run expansion path(e) Draw both the SRAC and the LRAC and explain why the SRAC is always equal or above the LRAC.arrow_forward4. Ikea Inc., a home remodeling business. The number of square feet they can remodel in a day is described by the Cobb-Douglas production function Q= F (L,K)= 4K5L0.5 where L is their number of workers and K is units of capital. The wage rate is $5 a day, and a unit of capital costs $20 a day. What is their minimum cost input combination for remodeling (Q=200) 200 square feet a day? What is the total minimum cost level?

- A firm estimates its production function as Q = -2.4 + 20*L -.5*L2 + 30*K -1.00*K2 + 15*F -.3*F2. Total cost is TC = $2*L + $2.5*K + $1.75*F. The firm wishes to produce 400 units of output. Use Excel to find the cost minimizing amounts of L, K and F. How much F (Fuel) should the firm use?arrow_forwardAnswer the question on the basis of the following cost data.

- A firm produces plastic bins using labor (measured in man-hours) and capital (measured in machine-hours), according to the production function Q = f(L,K) = LK, where Q is the number of plastic bins produced. Suppose that the cost of labor is $20 per worker-hour and the cost of capital is $10 per machine-hour. What is the cost minimizing input combination if the firm wants to produce 28,800 plastic bins? Hint: The marginal products are MP, = K and MPg = L.arrow_forwardYummy Gummies, Inc. makes boxes of individually packaged gummies.

The production function is f(L, M) = 4L1/2 M¹2, where L is the number of units of labor and M is the number of machines used. If the cost of labor is $49 per unit and the cost of machines is $16 per unit, then what is the total cost of producing 5 units of output?arrow_forwardA firm has the following information on production and costs from past data: Output (Y) 0 12 18 6 Total Cost (TC) 9 2775 5361 8199 If the total cost function is known to be TC = aY' + bY ² + kY + ƒ , and the demand for the product of the firm is Y = 320-(1/2). P answer the following: • Determine the coefficients of the cubic cost function. • Derive all cost and revenue curves and the profit function. Show that the MC cuts the AVC when AVC is at its minimum point. Plot the relevant graph indicating all points. Calculate the break even and profit maximizing levels of output and price. • What is the relationship between price, marginal revenue and own price elasticity of demand at the profit maximization point.arrow_forward
