Choco Dream is a firm that produces both dark chocolates as well as liquor chocolates. During a given month, the firm uses its resources to produce both varieties. Initially, the firm produced 5,000 bars of dark chocolates and 4,000 bars of liquor chocolates in a month. In order to increase production of the latter to 4,500, they had to reduce production of dark chocolates by 800 bars. When demand for liquor chocolates increased further, Choco Dream produced 5,000 bars of liquor chocolates and 3,200 bars of dark chocolates per month. Which of the following inferences can be drawn from the given information?
Choco Dream faces increasing marginal opportunity cost in the production of liquor chocolates.
Uber is a company that offers people transportation by drivers who use their own cars for this purpose. Customers pay for their rides with their smartphone apps. Uber's prices fluctuate with the demand for the service. This "surge pricing" can result in markedly different prices for the same distance traveled at different times of day or days of the week. Annie Lowrey, a writer for the New York Times, explained that she paid $13 for a 10 p.m. two-mile trip in downtown Washington, D.C. on New Year's Eve. Three hours later she paid $47 for the return trip to her home. Source: Annie Lowrey, "Is Uber's Surge-Pricing an Example of High Tech Gouging?" New York Times, January 10, 2014. Did she receive negative consumer surplus on her return trip?
Her willingness to pay was no less than $47, so she did not receive negative consumer surplus from this trip.

According to the FBI Bank Crime Statistics, there were nearly 4,000 bank robberies in the United States in 2014. The FBI claims that banks have made themselves easy targets by refusing to install clear acrylic partitions, called bandit barriers, that separate bank tellers from the public. According to a special agent with the FBI, "Bandit barriers are a great deterrent. We've talked to guys who rob banks, and as soon as they see a bandit barrier, they go find another bank." Sources: U.S. Department of Justice, Federal Bureau of Investigation, "Bank Crime Statistics (BCS) Federally Insured Financial Institutions, January 1, 2014-December 31, 2014," www.fbi.gov; and Richard Cowen, "FBI: Banks Are to Blame for Rise in Robberies," NorthJersey.com, March 10, 2009. Despite this finding, many banks have been reluctant to install these barriers. Wouldn't banks have a strong incentive to install bandit barriers to deter robberies? Why, then, do so many banks not do so?
Banks have no economic incentive to install the barriers.

A country that imports a substantial amount of gasoline every year imposed a $1.2 per gallon excise tax on gasoline, to be paid by sellers. The equilibrium price of gasoline prior to the tax was $4 per gallon. Gasoline being a necessary good, its demand curve is steep and the consumers had to bear the bulk of the tax burden. The post-tax price of gasoline went up to $5 per gallon, causing the country's media to claim that it was unfair that people should have to pay so high a price for such an important consumption item. They further believed that such a high tax was inefficient and could not be justified. Which of the following inferences can be drawn from this information?
The sellers of gasoline now receive 20 cents less than the pre-tax price.

[Related to Solved Problem #1] McDonald's typically serves breakfast until only 10:30 a.m. on weekdays and 11:00 a.m. on weekends. In 2015, the company began to experiment with serving breakfast all day at various locations in San Diego. Several owners of McDonald's restaurants, however, point out that offering breakfast 24 hours a day presents two logistical problems: (1) Burgers and other meats need to be cooked at a higher temperature than eggs, so it would be difficult for employees to set the grill at the right temperature for both foods; and (2) scrambled eggs require employees to continually stir, while hamburgers don't require this attention. In addition, some customers might buy the cheaper breakfast than the more expensive lunch or dinner meals. Source: Associated Press, "McDonald's Gives All-Day Breakfast a Test Try," usatoday.com, March 30, 2015; and Susan Befield and Leslie Patton. "What So Hard About a 24/7 McMuffin?" Bloomberg Busines Week, May 12, 2013. From an economics perspective, to determine whether to serve breakfast all day, McDonald's should
compare the marginal revenue from serving breakfast all day with the marginal cost of serving breakfast all day.
