Document Summary

Isoquant: the different combinations that can be used to produce an output. No costs there is no right and wrong answer. Add costs there is a right and wrong answer. About cost minimization because we are assuming: profit = tr - tc where tr is constant. Short-run: something is fixed, something can"t be changed, there is a constraint on production. Long-run: nothing is fixed, everything can be changed with enough time given, no constraint on production. Depreciation with respect to time no use. Sunk costs: cost that has happened that can"t be recovered. Good management decisions can"t be based on sunk costs: we get emotionally tied to sunk costs though they can"t be recovered. Fixed costs and sunk costs are not the same always though they can be. Opportunity cost: what you would do or receive in the second best option. Normal profit: fair return to labor and management; must be considered as an opportunity cost.

Redstone Clayworks Inc. is located in Sedona, Arizona, and manufactures clay fire pits for patios. They are one of about two dozen firms around the world that manufacture and sell clay fire pits for retailers such as Home Depot, Lowe's, Front Gate, and other upscale home product chains. There is virtually no product differentiation. A clay fire pit is a clay fire pit.

The spreadsheet below gives some of Redstone's production cost data.

Assume that the world market demand and supply curves for clay fire pots intersect at $190 per unit.

AFC = total fixed cost/total output.

AVC = total variable cost/total output.

ATC = total cost/total output.

MC = change in total cost/change in output.

Total revenue = price * quantity. And given that the demand and supply intersect at $190, which implies that the equilibrium price is $190 because the point where the demand equals the supply determines the price.

MR = change in total revenue/change in output.

Profit = total revenue - total cost.

Average profit = total profit/total output.

Profit margin = total profit/total revenue*100 or (revenue - cost)/revenue*100.

Question:

a. What level of output should the manager of Redstone choose to produce? Explain your choice in 50-100 words.

b. Make a copy of your spreadsheet and triple the fixed costs to 21,000. How does this change your answer to question a? Explain your result in 50-100 words.

A consultant has advised Consolidated Fish, Inc., a perfectly competitive firm, that it should cut back its production in order to increase its profits. We can conclude from this that

CF's total costs must be greater than its total revenues.

CF's marginal cost must be greater than the price of its product.

CF's costs are increasing at a rate less than its revenues.

fixed costs are not being covered and CF should shut down.

If marginal cost is equal to marginal revenue

the firm should hold output constant.

the firm should expand output.

there is no way to determine if the firm should expand output, contract output, or hold output constant.

the firm should contract output.

Which statement is true?

The minimum point on the firm's marginal cost curve is the shutdown point.

The minimum point on the firm's average variable cost curve is the shutdown point.

The minimum point on the firm's average total cost curve is the shutdown point.

The minimum point on the firm's marginal cost curve is the break-even point.

As output expands beyond the break-even point, the vertical distance between the AVC and ATC will

remain constant.

Total revenue divided by output equals

Oligopolists have more control over prices than monopolistic competitors because

their prices are always set by the government.

since an oligopolist is the only competitor in the market, setting prices is no problem.

they can legally collude whereas monopolistic competitors may not.

with fewer competitors, they are able to monitor and determine their own prices much easier.

The definition of monopolistic competition differs from that of perfect competition

in neither the number of firms nor the type of product.

in both the number of firms and the type of product.

with respect to the type of product.
