D. total revenue and total cost are equal

A firm reaches a break-even point (normal profit position) where: A. marginal revenue cuts the horizontal axis B. marginal cost intersects the average variable cost curve C. total revenue equals total variable cost D. total revenue and total cost are equal

B. upsloping and equal to the portion of the marginal cost curve that lies above the average variable cost curve

A purely competitive firm's short-run supply curve is: A. perfectly elastic at the minimum average total cost B. upsloping and equal to the portion of the marginal cost curve that lies above the average variable cost curve C. upsloping and equal to the portion of the marginal cost that lies above the average total cost curve D. upsloping only when the industry has constant costs

D. has all of these characterisitics

For a purely competitive firm total revenue: A. is price times quantity sold B. increases by a constant absolute amount as output expands C. graphs as a straight upsloping line from the origin D. has all of these characterisitics

D. all of these

For a purely competitive seller, price equals: A. average revenue B. marginal revenue C. total revenue divided by output D. all of these

D. a break-even point

In a typical graph for a purely competitive firm, the intersection of the total cost and total revenue curves would be: A. a point of maximum economic profit B. a point of minimum economic loss C. a point where MR=MC D. a break-even point

D. total revenue is less than total variable costs

In that standard model of the pure competition, a profit-maximizing entrepreneur will shut down in the short run if: A. marginal cost is greater than average revenue B. average cost is greater than average revenue C. average fixed cost is greater than average revenue D. total revenue is less than total variable costs

B. where the total revenue exceeds total cost by the maximum amount

In the short run a purely competitive firm that seeks to maximize profit will produce: A. where the demand and the ATC curves intersect B. where the total revenue exceeds total cost by the maximum amount C. that output where economic profits and zero D. at any pint where the total revenue and total cost curves intersect

B. marginal cost curve lying above the average variable cost curve

In the short run the individual competitive firm's supply curve is that segment of the: A. average variable cost curve lying below the marginal cost curve B. marginal cost curve lying above the average variable cost curve C. marginal revenue curve lying below the demand curve D. marginal cost curve lying between the average total cost and average variable cost curves

D. decrease in the short-run supply curve for a firm in the industry

Resource costs increase in a purely competitive industry. This change will result in a(n): A. increase in average fixed cost for a firm in the industry B. decrease in average variable cost for a firm in the industry C. decrease in the marginal cost curve for a firm in the industry D. decrease in the short-run supply curve for a firm in the industry

C. increase in the marginal cost curve for a firm in the industry

The wage rate increases in a purely competitive industry. This change will result in a(n): A. decrease in average total cost for a firm in the industry B. decrease in average variable cost for a firm in the industry C. increase in the marginal cost curve for a firm in the industry D. increase in short-run supply curve for a firm in the industry
