monopoly/lack of competition

AT&T, originally American Telephone and Telegraph, gradually gained more and more market share, particularly in long distance service, in the late 19th century. It did so by using patents (which it got from Alexander Graham Bell) to keep competitors from developing similar technology, and this worked until those patents began to expire. At that point other firms began to enter the market to compete, but AT&T aggressively bought some of these firms, which brought government scrutiny. In 1913 the government reached an agreement with AT&T: The company could not buy a phone company without also selling one. Instead of encouraging competition, however, this led to AT&T making deals with local phone companies to divide the country into territories over which AT&T or the local companies would have exclusive control. AT&T maintained complete and exclusive control over the wires that connected these local networks (this was called "long distance" service). This, combined with government-imposed prices, prevented competition from appearing in the telephone service markets. What kind of market failure best fits AT&T?

Starbucks=normal good Bean-lightened coffee=inferior good Andew's demand for coffee changed from=change in income In economic terms, coffee and creamer (or half-and-half, or whatever you prefer) are usually considered= complements

Andrew, a college student, loves drinking coffee late at night to study for exams. Having no income, he is used to buying cheap bad tasting coffee, such as Beanlightened, that he needs to grind and brew himself. The coffee tastes putrid but, with enough cream and sugar, Andrew is able to tolerate it. Occasionally, he does go out to Starbucks when he has spare money. After graduation, Andrew gets a job working at a database firm as a programmer. His income is now a healthy $75,000 a year and he decides he's had enough bad tasting coffee. He ends up buying coffee daily from Starbucks even though it costs significantly more than Beanlightened. Match each sentence beginning below with the phrase that ends it best.

the tragedy of the commons.

Back in the days before it was easy to lock down computers so that users couldn't screw them up, computers in computer labs tended to quickly be infected with viruses,spyware, and unnecessary programs. The failure of users to take care of these computers is an example of...

last-minute buyers of airline tickets.

Congressman Jerk McStupidface suggests a new tax on airline tickets bought at the last minute. Thinking about people who buy airline tickets at the last minute, airlines who sell them, and the way that affects pricing currently, you can conclude that the burden of this tax is likely to fall more heavily on...

a public good.

Consider the light from a lighthouse. Lighthouses shine light over bodies of water, so that ships do not run aground on reefs, shoals, sandbars, other dangers at sea. A ship that can see the light does not reduce the ability of other ships to see the light, and a crew that hasn't paid the lighthouse operator can't be excluded from seeing the light—anyone near the lighthouse can see the light. One could therefore argue that a lighthouse is an example of a...

There will be an increase in quantity supplied.

Economics

Goods with many substitutes will have an elastic demand, goods with few substitutes will have an inelastic demand

Elastic vs inelastic

Where price comes from 1. Resting place (where things move towards) 2.Place where two forces are equal

Equilibrium

1. Total surplus is maximized 2. Marginal benefit equals marginal costs 3. Every unit that produced has a benefit to the consumers that is greater than (or equal to) the cost of its production

Equilibrium is efficient means

Some of the costs or benefits of an action fall on a third party

Externalities

Represents marginal costs of producing an additional unit

Height of supply curve

Quantity demanded rises.

Flour, an input for cookies, is sold at $3 per bag= not a characteristic of the black market Fortune cookies are sold at $1.90 each=not a characteristic of the black market A Mrs. Field's chocolate chip cookie is sold for $8=characteristic of the black market The web cookie, an illegal delicacy prized for its distinctive icing decorations, is sold at the bazaar=characteristic of the black market

In the neighborhood of Sesame Street, cookies are in particularly high demand. The demand is, in fact, so great that prices for cookies are skyrocketing, and average citizens can no longer obtain this staple food. The government is considering a price control to keep cookies affordable for its citizens. As a result of the price control, a covert bazaar for cookies arises. Assuming the price control is set at $2 per cookie, sort the following statements into whether or not they describe black market activity.

Doing economic consulting.

Josephine teaches economics, and makes about $110,000 per year doing so. If she couldn't teach economics, she would be doing economic consulting for a major bank for $150,000 per year. If she couldn't work as an economic consultant, she would go back to school and study history. If she couldn't do that, she would stay at home and take care of the kids (her husband currently does this, but could go back to work if she couldn't find a job she liked). Which of the following is Josephine's opportunity cost of teaching economics?

1500

José is an illegal immigrant from Guatemala. Emma is a well-paid web designer who hires José to do some remodeling on her house. She offers José $5,000, but she would have been willing to pay him $5,500 (because that's how much she values the remodeling). José accepts, but he would have been willing to do the work for $4,000 (because that is how much he would earn doing work on a different house). What are the net gains to José and Emma that they get as a result of trading? You don't need to type a dollar sign with your answer; just enter a number.
