### Candy Cane Corporation (CCC) produces 100,000 boxes of candy bars per year which sell for \$3 a box. If variable costs are \$2 per box, and it has \$125,000 in fixed operating costs, in the short run the CCC should:

Keep producing as variable costs are covered

### When a purely competitive industry is in long-run equilibrium, which statement is true?

Price and average total cost are equal

Horizontal

### A purely competitive firm does not try to sell more of its product by lowering its price below the market price because:

It can sell all it wants to at the market price

### In pure competition, the demand for the product of a single firm is perfectly:

Elastic because many other firms produce the same product

A decreasing-cost industry

### Total revenue for producing 8 units of output is \$48. Total revenue for producing 9 units of output is \$63. Given this information, the:

Marginal revenue for producing the ninth unit is \$15

### Suppose that when 3000 units of output are produced, the marginal cost of the 3001st unit is \$2. This amount is equal to the minimum of average total cost, and marginal cost is rising. If the optimal level of output in the short run is 3300 units, then at this higher level of output marginal cost is:

Greater than \$2 and marginal cost is greater than average total cost

### In a purely competitive industry, each firm:

Can easily enter or exit the industry

### In pure competition, price is determined where the industry:

Demand and supply curves intersect

### A firm sells a product in a purely competitive market. The marginal cost of the product at the current output of 500 units is \$1.50. The minimum possible average variable cost is \$1.00. The market price of the product is \$1.25. To maximize profit or minimize losses, the firm should:

Produce less than 500 units

### The long-run supply curve under pure competition will be:

Downsloping in a decreasing-cost industry and upsloping in an increasing-cost industry

### Pure competition produces a socially optimal allocation of resources in the long run because:

Marginal cost equals price

### If firms enter a purely competitive industry, then in the long run this change will shift the industry:

Supply curve to the right, and the market price will decrease

### The representative firm in a purely competitive industry:

Will earn an economic profit of zero in the long run

### A firm should always continue to operate at a loss in the short run if:

It can cover its variable costs and some of its fixed costs

### When a purely competitive firm is in long-run equilibrium and is allocatively efficient:

Marginal cost equals marginal revenue

### Which is true for a purely competitive firm in short-run equilibrium?

The firm's marginal revenue is equal to its marginal cost

### The long-run supply curve would be up-sloping in:

An increasing-cost industry

### Market failure occurs when:

the competitive market system under-or overallocates resources to production of goods.

### From the economist's perspective, "market failures" basically arise when:

demand and supply do not accurately reflect all the benefits and all the costs of production.

### If an economy is being "productively efficient," then that means the economy is:

using the least costly production techniques.

### With allocative efficiency:

there is production of that particular mix of goods and services most wanted by society.

### Private goods are characterized by:

rivalry and excludability.

### Which of the following statements is correct about measuring collective demand for public and private goods?

Private good demand is found by horizontally adding individual demand curves; public good demand is found by vertically adding individual demand curves.

### In a market where there are external or spillover costs associated with consumption and production, the equilibrium will not be efficient because:

too many resources will be allocated to production of the good.

### If there are positive externalities associated with the consumption of a good or service:

the private demand curve will underestimate the true demand curve.

### If the production of a product or service involves external or spillover benefits, then the government can improve efficiency in the market by:

providing a subsidy to correct for an underallocation of resources.

### If the production of a product or service involves external or spillover benefits, then the government can improve efficiency in the market by:

much of the product at too low a price.

### One condition for individual bargaining to occur, according to the Coase theorem, is that there must be:

clearly defined property rights.

### To internalize the external costs of pollution is to:

make the polluter pay all of the costs associated with the polluting activity.

### The optimal level of pollution in society occurs whenever:

the marginal benefit of pollution control equals the marginal cost.

### Suppose that the ABC industry produces a product which results in significant spillover costs to society. Such production suggests that:

resources are overallocated to the industry.

### If an activity results in a spillover benefit, then in a pure market economy the:

quantity produced is too low.

A plant

An industry

### To the economist, total cost includes:

explicit and implicit costs, including a normal profit.

### Accounting profits are typically:

greater than economic profits because the former do not take implicit costs into account.

### Economic profits are calculated by subtracting:

explicit and implicit costs from total revenue.

### Suppose that a business incurred implicit costs of \$200,000 and explicit costs of \$1 million in a specific year. If the firm sold 4,000 units of its output at \$300 per unit, its accounting profits were:

\$200,000 and its economic profits were zero.

### Suppose that a business incurred implicit costs of \$500,000 and explicit costs of \$5 million in a specific year. If the firm sold 100,000 units of its output at \$50 per unit, its accounting:

profits were zero and its economic losses were \$500,000.

### To economists, the main difference between the short run and the long run is that:

in the long run all resources are variable, while in the short run at least one resource is fixed.

### The amount of calendar time associated with the long run:

varies from industry to industry.

### The long run is characterized by:

the ability of the firm to change its plant size.

### The law of diminishing returns indicates that:

as extra units of a variable resource are added to a fixed resource, marginal product will decline beyond some point.

### Marginal product:

may initially increase, then diminish, and ultimately become negative.

MP is zero.

### When total product is increasing at an increasing rate, marginal product is:

positive and increasing.

### When total product is increasing at a decreasing rate, marginal product is:

positive and decreasing.

### Fixed cost is:

any cost which does not change when the firm changes its output

### Average fixed cost:

declines continually as output increases.

### Marginal cost is the:

change in total cost that results from producing one more unit of output.

### Which of the following is correct as it relates to cost curves?

Marginal cost intersects average total cost at the latter's minimum point.

\$5,000.00

\$1,250.00

### Suppose that, when producing 10 units of output, a firm's AVC is \$22, its AFC is \$5, and its MC is \$30. This:

firm's total cost is \$270.

### If the total variable cost of 9 units of output is \$90 and the total variable cost of 10 units of output is \$120, then:

the average variable cost of 9 units is \$10.

the long-run average total cost curve rises.

### The minimum efficient scale of a firm:

is the smallest level of output at which long-run average total cost is minimized.

### The non-discriminating monopolist's demand curve:

is less elastic than a purely competitive firm's demand curve

### At the profit-maximizing level of output, a monopolist will always operate where:

Price is greater than marginal cost

### Suppose that a monopolist calculates that at present output and sales levels, marginal revenue is \$1.00 and marginal cost is \$2.00. He or she could maximize profits or minimize losses by:

Nonexistent

### A monopolist will definitely discontinue production in the short run if:

Price is less than average variable cost

### Which statement is correct?

Pure monopolists do not always realize economic profits

### The supply curve for a pure monopolist:
