Suppose that the U.S. government decides to charge cola consumers a tax. Before the tax, 40 billion cases of cola were sold every year at a price of $7 per case.

Darnell is training for a triathlon, a timed race that combines swimming, biking, and running. Consider the following sentence: Because his pool sessions are helping him swim more quickly, Darnell plans to reduce by 1 hour per week the time he spends training on the bike and increase by 1 hour the time he spends in the swimming pool; however, his wife says that he should stop doing any biking and running and spend all 20 hours per week in the pool. Which basic principle of individual choice does Darnell's plan illustrate that his wife's advice does not? A. Resources are scarce. B. All costs are opportunity costs. C. People usually exploit opportunities to make themselves better off. D. Many decisions are made on the margin.

C. People usually exploit opportunities to make themselves better off.

True or False: When both the demand and supply curves shift, the curve that shifts by the smaller magnitude determines the effect on the undetermined equilibrium object.

Suppose that both of the events you have just analyzed are partly responsible for the decrease in the price of hamburgers. Based on your analysis of the explanations offered by the two groups of students, how would you figure out which of the possible causes was the dominant cause of the decrease in the price of hamburgers?

If the equilibrium quantity of hamburgers increases, then the supply shift in the market for hamburgers must have been larger than the demand shift.

Because of the violent nature of the sport, professional American football players are at risk of suffering concussions (or brain injuries) during the violent collisions that occur between players during the game. Violent collisions involving hits to the head are particularly risky. Suppose the commissioner of the National Football League (NFL) institutes a rule requiring players to wear a new, lighter helmet that is designed to reduce head trauma during collisions between players on the field. While the new helmets ------- the probability of a concussion resulting from each individual collision, at the same time the new helmets could also give football players an incentive to play more ------- , which could potentially ------- the amount of violent collisions and thus the number of concussions suffered by NFL players, all else equal.

If Tim's boss is interested in a graphical representation of the relationship between the price and quantity of televisions demanded, you would advise your coworker to construct a ---- using the data provided. However, if Tim's boss is more interested in the detailed numbers used to construct this visual representation, you would instead advise your coworker that a ------ would be more appropriate.

Bob is a retired teacher who lives in San Diego and provides math tutoring for extra cash. At a wage of $20 per hour, he is willing to tutor 2 hours per week. At $35 per hour, he is willing to tutor 11 hours per week. Using the midpoint method, the elasticity of Bob's labor supply between the wages of $20 and $35 per hour is approximately2.54 Correct , which means that Bob's supply of labor over this wage range is ------

Consider some determinants of the price elasticity of demand: • The availability of close substitutes • Whether the good is a necessity or a luxury • How broadly you define the market • The time horizon being considered A good with many close substitutes is likely to have relatively ----- demand, since consumers can easily choose to purchase one of the close substitutes if the price of the good rises.

In addition to the positive welfare effects that free trade has on an economy, there are a variety of other benefits of international trade. Consider the following scenario: Without free trade, Rooby has market power as a local producer.
