Sparkle is one firm of many in the market for toothpaste, which is in long-run equilibrium.

Indicate which of the following graphs accurately reflects Sparkle's demand curve, marginal revenue (MR) curve, average-total-cost (ATC) curve, and marginal-cost (MC) curve.

The following graph shows Sparkle's demand curve, marginal-revenue (MR) curve, average-totalcost (ATC) curve, and marginal-cost (MC) curve.

Use the black point (plus symbol) to indicate Sparkle's profit-maximizing output and price.

The following graph shows Sparkle's demand curve, marginal-revenue (MR) curve, average-totalcost (ATC) curve, marginal-cost (MC) curve, and profit-maximizing output and price.

Suppose the government required Sparkle to produce the efficient level of output.

Which of the following describes what would happen to the firm and Sparkle's customers?

- Sparkle would earn positive profit and increase production, boosting consumer surplus.

- Sparkle would earn negative profit, forcing it to shut down, and Sparkle's customers would gain no consumer surplus.

- Sparkle would earn zero profit, and its customers would be just as well off as before.

Expert Solution

if price is reduced, P < ATC, so
Sparkle would earn negative profit, forcing it to shut down, and Sparkle's customers would gain no consumer surplus.

The long-run profit-maximizing equilibrium of a firm in monopolistic competition in many ways is similar as well as different from both under monopoly and that for a firm in a perfectly competitive market. Using three separate diagrams, articulate the differences and similarities (demand conditions, cost conditions and level of profits).

When a profit-maximizing firm in a monopolistic competitive market is in long-run equilibrium, marginal cost is rising since an increase in production would increase average total cost. true or false The product-variety externality associated with monopolistic competition arises because in markets that are monopolistic competitive markets, firms try to differentiate their products. true or false If the monopolistic competitive firm is currently producing output at a level where the marginal cost curve intersects the demand curve, then it is producing...

The market for sand is in long-run equilibrium with three producers, two high cost and one low cost. The market price is equal to the minimum ATC of the two (identical) high cost producers. Suppose the variable cost curve for the low cost producer shifts down, when shipping costs fall from the nearby port. Is the claim, “the price of sand falls in the long run,” true, false, or uncertain? Explain with a diagram.
