A perfectly competitive painted necktie industry has a large number of potential entrants. Each firm has an identical cost structure such that long-run average cost is minimized at an output of 20 units (qi = 20). The minimum average cost is $10 per unit. Total market demand is given by Q = 1,500 – 50P (a) What is the industry's long-run supply schedule?
(b) What is the long-run equilibrium price (P*)? The total industry output (Q*)? The output of each firm (qi*)? The number of firms? The profits of each firm?
(c) The short-run total cost curve associated with each firms long-run equilibrium output is given by STC = 0.5q2 – 10q + 200 where SMC = q – 10. Calculate the short-run average and marginal cost curves. At what necktie output level does short-run average cost reach a minimum?
(d) Calculate the short-run supply curve for each firm and the industry short-run supply curve.
(e) Suppose now painted neckties become more fashionable and the market demand function shifts upward to Q = 2,000 – 50P. Using this new demand curve, answer part (b) for the very short-run when firms cannot change their outputs.
(f) In the short run, use the industry short-run supply curve to recalculate the answers to part (b).
(g) What is the new long-run equilibrium for the industry?

The cost of capital: introduction the cost of capital: introduction companies issue bonds, preferred stock, and common equity to aise capital to invest in capital budgeting projects. capital is』necessary factor of production and like any other factor, it has a cost. this cost is equal to the select the applicable security. the rates of return that investors require on bonds, preferred stocks, and common equity represent the costs of those securities to the firm. companies estimate the required returns on their securities, calculate a weighted average of the costs of their different types of capital, and use this average cost for capital budgeting purposes. required return on rate: when calculating om operations when the firm's primary financial objective is to select shareholder value. to do this, companies invest in projects that earnselect their cost of capital. so, the cost of capital is often referred to as the -select -select and accruals, which a se spontaneously we hted average cost of capital wa c our concern is with capital that must be provided by select- 쑤 interest-bearing debt preferred stock and common equity. capital budgeting projects are undertaken, are not included as part of total invested capital because they do not come directly from investors. which of the following would be included in the caculation of total invested capital? choose the response that is most correct a. notes payable b. taxes payable c retained earnings d. responses a and c would be included in the calculation of total invested capital. e. none of the above would be included in the cakulation of total invested capital.

The rybczynski theorem describes: (a) how commodity price changes influence real factor rewards (b) how commodity price changes influence relative factor rewards. (c) how changes in factor endowments cause changes in commodity outputs. (d) how trade leads to factor price equalization.
