a monopoly produces less output and sells for a higher price
A monopoly is less efficient than a perfect competitor because
halfway between the demand curve and the vertical axis
A monopoly with a straight, downward-sloping demand curve has a marginal revenue curve that is
A wage payment lower than the marginal revenue product of labor.
A monopsonist is identified by one of the following:
wages are depressed and fewer workers are hired
A monopsony occurs when there is only one buyer for a specific good (for example, a large company in a small town is virtually the only buyer of labor). As the buyer is interested in maximizing its own revenue, the net result is that
substitutes.
A positive sign on cross price elasticity of demand indicates that the two products are
a price set below the current (or equilibrium) market price of the good.
A price ceiling is characterized by
earns more revenue than a non-discriminating monopoly
A price discriminating monopoly differs from a non-discriminating monopoly because a discriminating monopoly

The total utility this student received from eating pizza is 20 utils.
A student eats 3 slices of pizza while studying for his Economics exam. The marginal utility of the first slice of pizza is 10 utils, the second slice is 7 utils, and the third slice is 3 utils. Which of the statements below holds true with the above data?
Regressive
Because people with relatively low incomes spend a larger percentage of their income on food than people with relatively high incomes, a sales tax on food would fall into which category of taxes?
the cost of milk, which is used in the production of ice cream, rose
In the graph above, the shift in the supply curve from S to S1 for ice cream could occur because
1. Productive efficiency: they produce the quantity that is the lowest cost (Minimum ATC) 2. Allocative efficiency: they produce the optimal quantity that society wants (Price = MC)
In the long run, perfectly competitive firms have both types of efficiency:
minimum point on average variable cost.
In the short run, the shut down price is equal to
it is producing at the point at which its revenues most exceed its costs.
When a firm produces at a point where MR = MC, then it is maximizing its profits, which is to say that
resources are being used fully and efficiently.

When opportunity cost is constant across all production levels, the productions possibilities frontier is

This is short run diminishing marginal productivity.

the buyer or seller.
externalities are incidental costs that are not accounted for by

In an oligopoly market, firms
diminishing marginal utility
A demand curve slopes downward for an individual as the result of
a monopsony buys from a monopoly
A bilateral monopoly exists when
the marginal (physical) product of labor and the output price
A competitive firm's demand for labor is determined directly by
price elasticity of demand is highly inelastic.
A tax imposed on a supplier will more likely be passed on to the consumer in the form of price increase if
marginal utility decreases with each additional unit of a good that is consumed.
According to the principle of diminishing marginal utility,
ABG.
After the monopolist enters, the consumer surplus is
results in an equilibrium that does not maximize the total benefit to society
An externality
The firm should hire more labor so that the MRPL will decrease. (If the third worker's MP = 10, then that worker generated income of 10 × $3 = $30. As the worker is paid $15, the firm is making economic profit. Therefore it should hire more workers until the productivity of the last worker just equals the revenue generated by that worker).
Assume a firm hires labor for $15 each and sells its products for $3 each. If the MP of the 3rd worker is 10, which of the following statements would be the most true?
Tax the firm.
If there is a negative externality associated with the production of a private good, which of the following is an action by government that would most likely move the market to an efficient outcome?
lead the firm to hire more workers but not to raise their wages
Consider a profit-maximizing firm in a perfectly competitive market with several sellers and several buyers (i.e., the firm is a "price taker" of the goods it sells and a "price taker" of the hourly wages it pays its workers). If a technological innovation made by someone in this firm were to significantly raise the firm's marginal physical product (but not that of any other firm's), then this innovation would
the difference between the consumer's value and the market price.
Consumer surplus is
Subsidize the firm or its customers.
If there is a positive externality associated with the production of a private good, which of the following is an action of government that would most likely move the market to an efficient outcome?
D to E
Economic growth is best represented by a movement from
negative (pollution).
Externalities can be positive (vaccinations) or
MC = MR.
Firms maximize their profits by producing a level of output at which
Output would decrease, price would increase.
For a polluting steel company, a government action to most likely achieve an optimal or efficient outcome would produce what effect on the market equilibrium price and output?
PDEP2
For this monopolist profit is the area represented by
supply is elastic
If a 3 percent increase in price leads to a 5 percent increase in the quantity supplied,
increase price because demand is inelastic
If a business wants to increase its revenue and it knows that the demand price elasticity of its product is equal to 0.78, it should
The demand curve will shift to the right, increasing the price of multigrained bread.
If consumers are advised that multigrained bread will substantially lessen the risk of cancer, which of the following will happen in the market for multigrained bread?
There would be no change in the amount of corn demanded or supplied. (Remember that a price ceiling sets a maximum price a producer may charge. Since the price ceiling (PC) is above the equilibrium price, the equilibrium price and quantity do not change as a result of the price ceiling).
If corn is produced in a perfectly competitive market and the government placed a price ceiling above equilibrium, which of the following would be true?
hire more capital (K) until the ratios are equal.
If for two resources, Labor (L) and Capital (K), the ratios of their marginal physical products are MPPK/PK = MPPL/PL the firm should:
marginal benefit would be less than marginal cost

The deadweight loss in this market would decrease.
If the government regulates a monopoly to produce at the allocative efficient quantity, which of the following would be true?
the consumer surplus will increase
If the government subsidizes producers in a perfectly competitive market, then
the supply curve will shift to the right.
If the government subsidizes the production of halogen headlights,
income effect.
If the price of a product decreases so that the consumer can buy more of it and other products, this is called the
substitution effect.
If the price of a product decreases with the price of a substitute product remaining constant such that the consumer buys more of this product, this is called the
E d = 1/5 and demand is price inelastic.
If the price of corn rises 5 percent and the quantity demanded for corn falls 1 percent, then
market prices are determined by a central plan designed by the government
In a command economy,
MC intersects AVC and ATC at their minimum points.
Marginal cost (MC) is equal to average variable cost (AVC) and average total cost (ATC) when:
the minimum of average variable cost
Marginal cost always intersects average variable cost at
total revenue is greater than total cost at its greatest distance
Marginal revenue equals marginal cost at the point where

Normal goods always have a/an

Opportunity costs or implicit costs of a "Mom & Pop"-owned business are:
- the most substitutes available for consumers - the greatest degree of elasticity - the largest number of sellers - is not a price maker
Perfect competition has/is
any company that can engage in price discrimination will earn higher revenues than those companies that do not.
Price discrimination occurs when a company can charge different prices to different customers for essentially the same product. Therefore

Price times quantity measures

Production possibilities frontiers are concave to the origin because

Typically in oligopolistic markets there are several buyers and few sellers. Therefore
