Two students in an economics class, Harry and Sally, are discussing the problems with gender discrimination in the labor market. They both agree that men and women should be treated equally. Sally claims that the significant differences in the ratio of men to women in the market for construction workers, a relatively higher-paying field, compared to grocery clerks, a relatively lower-paying field, is abhorrent and a result of discrimination. Harry responds using the analysis he learned in the lecture on labor supply. Harry tells Sally,
"This is not necessarily discrimination. Construction work requires a lot of physical labor and women may not prefer it. Thus it could be the result of differences in gender preferences."
The accompanying graph depicts the labor markets for sanitation workers and landscapers. Both occupations face identical labor demand curves (Demand). However, labor supply differs. Supply 1 represents the supply of labor of sanitation workers, and Supply 2 represents the supply of labor for landscapers. Assume that the skills and education necessary for each job are identical. What is the difference in equilibrium wages between the two occupations? What might explain the different equilibrium wages for these occupations?
$10 The supply of sanitation workers is lower due to the unpleasantness of the job, which results in a compensating differential.
The graph represents a labor market. a. What is the equilibrium hourly wage? b. What is the equilibrium number of hours worked? c. Identify all the factors that would cause the equilibrium wage to increase. It would increase with
$5 per hour 12 hours an increase in labor demanded, a decrease in labor supplied

Miles is three years old and his grandparents have given him money to spend at the toy store as a birthday present. Miles' number one favorite thing to play with is building blocks. Assume that Miles' utility will increase by 100 units if he purchases a new set of building blocks and and it will cost him $50. His second favorite thing to play with is fire trucks. Fire trucks cost $20 and each new fire truck improves Miles' utility by 80 units. His third favorite toy is trains. Trains improve his utility by 15 units and cost $5 each. Miles does not have to spend all of his money at once, but wants to get as much happiness as possible from his money.

Kat is deciding if she would like to join the customer loyalty plan at Bonsai Plants and Books. For simplicity, suppose that she and Patrick are the only consumers at Bonsai Plants and Books.

If Patrick also joins then the deals are not that great, but outsiders are the worst off in both cases. This is the prisoner's dilemma. What is the Nash equilibrium?
Both join

A futures contract essentially gives the owner of the contract the ability to buy a specific amount of a good at a given price at a point in the future. In a 1984 paper titled Orange Juice and the Weather, economist Richard Roll showed that the price of frozen orange juice futures could be used to predict errors in weather forecasts for Florida made by the National Weather Service. That is, there were times when the price of orange juice futures did a better job of predicting the temperatures in Florida than did the National Weather Service! Given this information, what would the efficient markets hypothesis suggest was occurring?
Investors in orange juice futures were using publicly available information that scientists at the National Weather Service were not using.

Tournament systems reward people according to their performance relative to other contestants. One advantage is that variables beyond the control of the contestants affect them all without favoring any one of them. One disadvantage is called ability risk.

Which scenario demonstrates the reduction of ability risk? Which is most likely to be true about a tournament?

Eva and Bruce are a young couple in good health. Eva begins her new job as a dolphin trainer and is offered elective health care coverage from her company for a price less expensive than she and Bruce would pay if they purchased insurance on their own.

Identify which manifestation of subjective values best relates to each scenario. a. Surrogacy is when in vitro fertilization is used by a couple in order to have a child using a third party, i.e., a surrogate woman.

Please label each definition with the correct term. Many purely rational decisions in economics may go against this principle, which seeks to treat all people the same, regardless of any difference that might exist between them. Some governments use tax dollars to subsidize special programs and projects, even if citizens choose to spend their money on things other than those programs and projects. Sometimes, a person's opinion about other individuals' actions can lead the person to seek change. An individual in a more opportune position takes advantage of another individual for his own economic gain.
