Surplus

Firms produce a homogeneous product

0.67

Less than or greater than the competitive equilibrium quantity

In the short run, total product begins to decrease at the point where the:

Marginal product of labor is zero

Marginal revenue for producing the ninth unit is $15

Which is not a basic market model?

Free enterprise

With a natural monopoly, the fair return price:

Is allocatively inefficient; the socially optimal price is allocatively efficient

One argument for requiring the government to regulate natural monopolies is that:

Without regulation these monopolies produce at a level where marginal benefit is greater than marginal cost

If you know that when a firm produces 10 units of output, total costs are $1,030 and average fixed costs are $10, then total fixed costs are:

$100

Which is most characteristic of a purely competitive monopoly?

The firm produces a good or a service for which there are no close substitutes

Blossom, Inc. sells 500 bottles of perfume a month when the price is $7. A huge increase in resource costs forces Blossom to raise price to $9, and the firm only manages to sell 460 bottles of perfume. The price elasticity of demand is:

0.33 and inelastic

When the price of a product is increased 10 percent, the quantity demanded decreases 15 percent. The price-elasticity of demand coefficient for this product is:

1.5

Suppose you are given the following data on demand for a product. The price elasticity of demand (based on the midpoint formula) when price decrease from $9 to $7 is:

1.60

The following cost data are for a firm operating in the short run. Other things equal, diminishing returns begin to set in with the production of which unit of output?

4

Assume the price of a product sold by a purely competitive firm is $5. Given the data in the accompanying table, at which output is total profit highest in the short run?

40

If the price elasticity of demand for a product is equal to 0.5, then a 10 percent decrease in price will increase quantity demanded by:

5 percent

Suppose a consumer has an income of $16, the price of A is $2, and the price of B is $1. Which combination is on the consumer's budget line?

5A and 6B

Assume that the only variable resource used to produce output is labor. Refer to the above table. When the firm hires four units of labor the average product of labor is:

7.50 units of output

With fixed costs of $400, a firm has average total costs of $3 and average variable costs of $2.50. Its output is:

800 units

An indifference curve shows:

All combinations of two products from which the consumer derives the same total utility

A profit-maximizing firm should shut down in the short run if the price it receives is less than:

Average variable cost

If marginal cost is below average variable cost:

Both average total cost and average variable cost are decreasing

A nondiscriminating pure monopolist is generally viewed as:

Both productively and allocatively inefficient

A decrease in money income cause the consumer's:

Budget line to shift inward to the origin

Decreases in the price of a product causes the consumer's:

Budget line to shift outward from the origin

The information-aggregation problem faced by the top layers of government can make it hard for the high-level officials to:

Comprehensively assess the marginal costs and benefits of specific programs

Normal profits are:

Considered an implicit cost by economists

A leftward shift of a consumer's budget line to a position parallel with the original one could indicate that the:

Consumer's money income has increased but the prices of both products have increased proportionately more

In the graph above, a decrease in the price of television sets will lead the consumer shown to:

Decrease her demand for lasagna

If many people in a community get flu shots, the whole community benefits including those that did not get flu shots. Therefore, not enough people may decide to get the shots. This is one illustration of:

Demand-side market failure

Government in a market system can increase economic efficiency by collecting taxes in order to subsidize the production of:

Goods with positive externalities

One key is difference between government activities and private transactions is that:

Government can enforce involuntary transactions, whereas private transactions are mostly voluntary

The marginal rate of substitution of good A for good B defines:

How many units of good B a consumer is willing to give up when he receives one extra unit of good A, holding his total utility constant.

Under pure monopoly, a profit-maximizing firm will produce:

In the elastic range of its demand curve

Assume there is no way to prevent someone from using an interstate highway, regardless of whether or not he or she pays for it. This characteristic is called:

Nonexcludability

When producers do not have to pay the full cost of producing a product, they tend to:
