A field experiment at an all-you-can-eat pizza restaurant shows that a 50% discount on the price of the meal led customers to consume 27.9% less pizza. In other words, when people have to pay a higher price for their meal, they want to "get their money's worth" by eating more pizza. 10) Suppose the regular price of the buffet is $10 and the discounted price is $5. Once a customer has paid for the buffet, what is the marginal cost of eating another slice of pizza? (Assume the only costs are monetary costs.) A) $0 B) $5 C) $10 D) It depends on whether the customer is getting a discount.

A) $0

Carly Rae Jepsen released her new album on the same night that Taylor Swift released hers. Taylor Swift's album got most of the attention - it was immediately written about in major publications, teaser clips for the music videos were shown on Thursday Night Football, and the album was streamed 185 million times on Spotify in one day. Journalists have a limited amount of time to write and fans have a limited amount of time to listen to music, so Carly Rae Jepsen's album received less fanfare than it would have received if it had been released a week earlier. This is an example of which type of externality? A) A common resource problem B) Intergenerational externalities C) Network effects D) Thick market externalities

A) A common resource problem

But the complexity of the drinks, along with order surges at certain times of the day, have made barista jobs more demanding and can sometimes result in delays. To help address that, the company unveiled a new cold beverage system that reduces the number of steps needed to make the drinks, as well as the need for employees to repeatedly bend down and dig into buckets for ice.

Before the pandemic, around 5% of the roughly 25,000 annual customers of Three Kings Tattoo were ages 50 or older. Owner Matthew Marcus estimated that the 50-plus crowd now make up about 15% of the clients at his seven locations, which include New York, Los Angeles, Denver and London. Many of them arrive with grown children or grandchildren for matching tats. "The pandemic created more of a YOLO mentality in people," said Mr. Marcus, using the you-only-live-once acronym.

A single country has accounted for about 80 percent of the fishing in the international waters just off Argentina, Ecuador and Peru this year. And it is not a South American country. It is China. In recent years, hundreds of Chinese fishing vessels have begun to operate almost 24 hours a day, seven days a week, off the coast of South America. The ships move with the seasons, from Ecuador to Peru to Argentina. China has focused on these faraway waters after depleting fish stocks closer to its own shores. China's fishing expansion is part of a much larger story, of course. As the world's most populous country, and one with an economy that has grown rapidly in recent decades, China has a growing global footprint — economically, diplomatically and militarily. It needs so much fish to feed a middle class that has become vastly larger over the past generation. For the purposes of this problem, we can assume that there have been no new technologies making it easier to harvest fish. So, the marginal cost curve for producing fish is unchanged. Which of the following best describes what happened to the market for fish as China's middle class has grown: A) There was an increase in demand and an increase in quantity supplied B) There was an increase in demand and an increase in supply C) There was a decrease in demand and a decrease in quantity supplied D) There was an increase in demand and a decrease in supply

A) There was an increase in demand and an increase in quantity supplied

B) This ban will destroy American jobs in the electric-powered-scooter industry C) This ban will hurt the wages of manufacturing workers in other countriesD) This ban will increase the price that people in other countries pay for electric scooters

A) This temporary ban might become permanent because the electric scooter manufacturers

McDonald's has been promoting the "McRib Farewell Tour", encouraging customers to purchase the sandwich and suggesting that it may soon be permanently removed from the menu. This is one of McDonald's many recent marketing moves that have led the Wall Street Journal to claim "McDonald's is Cool Again". That article notes that McDonald's is seeing increased visits to its stores and increased revenue. How would we expect this to affect the wages of McDonald's workers? A) Wages increase because labor demand increases B) Wages increase because labor demand decreases C) Wages increase because the supply curve of McRib sandwiches shifts to the right D) Wages increase because the labor supply curve shifts to the left

A) Wages increase because labor demand increases

Continuing with the previous question, suppose that some of the 185 million people who streamed Taylor Swift's album Midnights on Spotify were not regular Spotify users. They logged on just to listen to Midnights, but once on the app, they started listening to more music by lesser-known artists. Had these people not logged on to Spotify for Midnights, they never would have heard of these artists and never would have listened to their music. For the lesser-known artists, this is an example of ________: A) A public good B) A positive externality C) A negative externality

B) A positive externality

A field experiment at an all-you-can-eat pizza restaurant shows that a 50% discount on the price of the meal led customers to consume 27.9% less pizza. In other words, when people have to pay a higher price for their meal, they want to "get their money's worth" by eating more pizza. After the researchers conducted this part of the experiment, they did another analysis. They surveyed the customers after they ate and asked them to rate the taste of the pizza. Based on what we have learned about diminishing marginal benefits, who would we expect to give the pizza a higher rating? A) Customers who paid the higher price, because the pizza is worth more to them B) Customers who paid the lower price, because they didn't eat as many slices and therefore avoided the slices that gave a lower marginal utility

B) Customers who paid the lower price, because they didn't eat as many slices and therefore avoided the slices that gave a lower marginal utility

Maria is deciding how big of a house to build. She gets decreasing marginal benefits from house size (so, the marginal benefit of the first square foot is greater than the marginal benefit of the second square foot and so on).

B) The Jonas Brothers tickets

A field experiment at an all-you-can-eat pizza restaurant shows that a 50% discount on the price of the meal led customers to consume 27.9% less pizza. In other words, when people have to pay a higher price for their meal, they want to "get their money's worth" by eating more pizza. This actually does not fit with what we have learned about rational decision making and how people make decisions on the margins. Why? A) The customers are not accounting for the opportunity cost of eating pizza instead of another meal B) The marginal cost of a slice of pizza is zero for all customers, so all customers (whether or not they are receiving a discount) should consume until the point where the marginal benefit of the last slice of pizza is zero. This means that the price paid should not affect consumption C) The marginal cost of a slice of pizza is greater for customers paying the higher price. This means that marginal benefit will equal marginal cost at a lower quantity, so consumers paying a higher price should eat less pizza.
