Exam 14: Perfect Competition

The table given below shows the price of each unit of the product manufactured by a firm and the marginal cost of producing different units of the output. Table: 9.1 According to the information in Table 9.1, this firm will maximize profit when total output is equal to _____ units.

The figure given below shows the revenue and cost curves of a perfectly competitive firm. Figure 9.2 MC: Marginal cost curve MR: Marginal revenue curve ATC: Average-total-cost curve AVC: Average-variable-cost curve Refer to Figure 9.2.If the market price falls to $10, the firm would produce:

For a perfectly competitive firm in the short run, which of the following statements is true?

When the perfectly competitive firm's demand curve lies above its average total cost curve, the firm incurs an economic loss at that level of output.

The governmental interference with the market exchange often reduces the total surplus.

If a firm in a perfectly competitive market raises its price:

The perfectly competitive producer's demand curve is:

The figure given below shows the demand and cost curves of a perfectly competitive firm. Figure: 9.4 D: Demand curve MC: Marginal cost curve ATC: Average-total cost curve AVC: Average-variable-cost curve Refer to Figure 9.4.The presence of the average-variable-cost curve suggests that the firm is operating:

Graphically, consumer surplus is the area:

Under perfect competition, existing firms leave the market in the long run if the price falls below total fixed cost.

The profit of a perfectly competitive firm is maximized at a level of output where its marginal cost is rising.

In the short run a competitive firm is said to break-even if, at the equilibrium:

The figure given below shows the revenue and the cost curves of a perfectly competitive firm. Figure 9.3 In Figure 9.3, the profit maximizing output of the firm is _____ units.

The table given below shows the price of each unit of the product manufactured by a firm and the marginal cost of producing different units of the output. Table: 9.1 Refer to Table 9.1.The firm depicted in the table is a(n):

If significant barriers to entry exist in a market, then the market is best described through the model of perfect competition.

Which of the following faces a horizontal demand curve?

In long-run equilibrium in perfect competition, the entry and exit of firms will drive economic profits to zero.

Some competitive firms are willing to operate at a loss in the short run because:

Why do the perfectly competitive firms earn only normal profits in the long run?

Some competitive firms are willing to operate at a loss in the short run because their revenues are at least able to cover their variable costs.
