Given the information that the market for smart phones is inefficient, which of the following statements explains why consumers of smartphones might still not want the price to be regulated?

It would reduce product variety

three factors of production

Land, labor, capital

marginal product of labor

change in output that occur when hiring one more employee

marginal product

the increase in output that is generated by an additional unit of input

gains from trade

the increase in welfare in both countries that results from specialization and trade

value of the marginal product

the marginal product generated by an additional unit of input times the price of output

When a producer has the ability to produce a good or service at a lower opportunity cost than others, economists say:

the producer has a comparative advantage at producing that good

human capital

the set of skills, knowledge, experience, and talent that determine the productivity of workers

Consider Jimmy Choo designer shoes. Jimmy Choo faces many competitors, while in another way Jimmy Choo faces no competitors. This contradiction can be explained by:

the substitutability between Jimmy Choo shoes and other shoes

If the cross-price elasticity of two goods is 0.25, then we know that

those goods are substitutes because their elasticity is greater than zero

price effect

what you gain from a price increase because people pay more

quantity effect

what you lose from a price increase because people buy less

In general, the income effect of an increase in the price of a normal good:

will cause the individual to buy less of that good because they have relatively less income

a government-owned monopoly is more likely to

- provide a greater quantity of output than a private one - provide output at a lower price than a private one - serve public interest than maximize profit

Autarky

An economy that does not import or export

If Argentina becomes a net exporter of beef after trade barriers are removed, what will happen to the following compared with autarky?

- Argentine cattle ranchers will be better off - Argentine consumers will be worse off - Total welfare in Argentina will increase

Effects of quota

- Decreases amount of imports - Increases import price

Effects of tariff

- Increases the world price for domestic consumers - Decreases the amount of shortage made up by imports

McDonald's, Burger King, and Wendy's all produce hamburgers, among other things. However, if you prefer burgers from McDonald's, you might consider other burgers an imperfect substitute. What is correct about McDonald's prices in the short run?

- McDonald's will charge a price higher than marginal revenue and marginal cost - McDonald's will set its prices like a monopolist - McDonald's will maximize profit by producing where MC=MR - McDonald's consumers will pay higher price as long as it is equal to how much they value a burger from McDonald's

Suppose a perfectly competitive market for hot dog stands in New York City becomes monopolistically competitive when gourmet, discount, and ethnic hot dog retailers show up, making each cart slightly different. If hot dogs from different stands are now imperfect substitutes and there are numerous carts in the city, compare the following measurements in the short run before and after the change:

- Producer surplus will increase after the change. - Consumer surplus will decrease after the change. - Total social welfare or surplus will decrease after the change. - Price variance between different vendors will be higher after the change.

Compare perfectly competitive markets, monopoly markets, and oligopoly markets on the following economic behavior:

- Producers maximize profit by producing where MR = MC in all three types of markets - The efficient outcome is to produce where P = MC in all three types of markets - The efficient outcome is achieved in perfectly competitive markets only - Market price is greater than marginal revenue (MR) in monopoly markets and oligopoly markets only - Some form of barriers to entry exist in monopoly markets and oligopoly markets only - If they collude, oligopolies will produce at the same level as monopolies

Explain why a country that is more productive than its trading partners in producing wheat would end up importing wheat anyway.

- The country is even more productive in goods other than wheat - The country has comparative advantage in goods other than wheat - The country's trading partners can produce wheat at a lower opportunity cost

Suppose Egypt wants to open its trade borders to the world market for natural gas. What would make Egypt a net exporter of natural gas?

- The domestic price of natural gas being less than the world price - Egyptian comparative advantage in natural gas - Government ownership of natural resources

Large telecom companies like AT&T routinely send repair technicians to customers' homes. Although the technicians are skilled laborers, they must usually train on the job. It takes some time for them to reach a high standard of quality. In addition, their work cannot be constantly supervised. Explain why an efficiency wage could help telecom companies increase the productivity of repair technicians.

- efficiency wages are above the equilibrium wage - workers that receive efficiency wages have a greater incentive to work hard

2 examples of common resources

- fish in a river - forests

Essential characteristics of a perfectly competitive market

- goods are standardized - buyers are price takers - no transaction costs - no barriers to entry for producers - there are many buyers and sellers in market

Leo runs a bicycle repair shop. He recently examined his information on wage and employment levels and noted that he employed the same number of workers in 2009 as he did in 2013. However, real wages (controlling for inflation) increased quite substantially between 2009 and 2013. Assume the supply of labor remained constant over this time period. What are two possible explanations for why Leo's workers were paid more in 2013?

- marginal product increased during this time (workers are more productive) - the price of repairing a bicycle was higher in 2013 than in 2009

An oligopolist (with few competitors) pays more attention to what his competitors are doing than a producer in a competitive market (with many competitors) does because:

- oligopolists are not price takers - perfect competitors have so many competitors that their revenues depend on the market as a whole rather then the actions of individual competitors - the actions of one oligopolist impacts the revenue for all the other oligopolists

If a Pigovian tax is not large enough, the resulting:

- outcome will not maximize surplus - quantity will be too high - outcome will be inefficient

2 examples of artificially scarce goods

- private pools - pay-per-view

Explain why governments are usually more concerned about regulating an oligopoly than a monopolistically competitive market?

Oligopolies are always more inefficient than monopolistically competitive markets

What holds true at the chosen level of output in the long run for firms in a perfectly competitive market?

P = MC MC = MR P = minimum ATC

Suppose an auto manufacturer has one factory in the United States and one in Mexico. The auto manufacturer produces the same number of cars and the same models in each factory but hires more workers in Mexico than in the United States. Give an explanation for the discrepancy in the amount of labor hired in each location.

The US plant has more capital per worker

Suppose a cafe owner wants to switch to automatic espresso machines instead of paying baristas to pack the coffee grounds by hand. The machines are twice as effective as a human, the fixed cost per machine equals the yearly wage of one employee, and each machine needs to be replaced every 3 years. Assume further that the quantity of espresso bought and sold remains constant. Explain how the equilibrium price (wage) and quantity of labor will change.

The equilibrium price (wage) and quantity of labor will both decrease

Costly advertising sends a credible signal of product quality

A market has few barriers to entry and many firms. Which of the following is a strategy that a firm can use in this type of market to gain and maintain economic profits?

Create a sense of product uniqueness among consumers

It is the case in both perfectly competitive and monopolistically competitive markets that other firms will enter when firms are making positive economic profits, until price eventually equals ATC and economic profits are zero. Despite these similarities, in a perfectly competitive market total surplus is maximized, while in a monopolistically competitive market surplus is not maximized. What explains this difference?

In perfectly competitive markets, firms operate where MR is equal to MC, which is where ATC is minimized
