In a study at a large state university, students were randomly assigned roommates. Researchers found that, on average, mates assigned to roommates who reported drinking alcohol in the year before entering college earned GPAs one-quarter point lower than those assigned to non-drinking roommates, for males who drank frequently before college, being assigned to a roommate who also drank frequently before college reduced their GPAs by two-thirds of a point. Draw a graph showing the price of alcohol and the quantity of alcohol consumption on college campuses. Include in the graph the

- Consider the market for CD players, illustrated in the figure to the right. Suppose there are network externalities in this market such that the quantity of a good demanded grows in response to the growth of purchases by other individuals (as indicated by the demand curve "Demand" in the figure). Suppose that the price is initially $90 where the quantity demanded is 120 (thousand CD players per month). If the price of CD players falls to $50, demand will increase to 180 thousand CD players per month. (Enter your response using an integer.) Of this increase, price effect and thousand units of the 60 thousand-unit increase is the pure thousand units of the increase is the bandwagon effect.

Demand for traffic (measure as traffic volume per minute) on this road is T=6,880 -– 70.(1/S). a. Find the equilibrium traffic volume in the absence of any congestion tollI. b. Find the marginal cost function for traffic volume, where cost is expressed as travel time per mile in minutes. c. Find the optimal level of traffic volume. d. Find the optimal congestion toll, expressed in minutes. (Imagine that the congestion toll consists of sitting in the "penalty box" for this period of time.)arrow_forwardA local school administrator is concerned that flu outbreaks are putting children at risk, so she proposes that the state should subsidize flu shots in order to increase coverage rates. -Are the administrator’s concerns valid—are too few children getting flu shots—and will a subsidy help? -The school nurse suggests publishing a list of which kids did not get a flu shot, in the hope that public shaming will lead people to vaccinate their children. Is this strategy likely to work?arrow_forward
- According to a researcher at the FDA, vegan foods are “the way if the future”. Morepersons have become health conscious and are looking for foods which will fit thislifestyle. One such food is the Beyond Burger, a plant-based alternative to beef. Notably,despite strong demand for beef burgers, the supply chain has seen a host of disruptionsthat are preventing producers from getting their products to market.Beyond Burger’s sales in Canada totaled $3.0 billion at the end of 2021, accounting for20% of all retail sales of burger patties (meat used in burgers), and 40% of the largermarket for vegan foods. By the end of 2025, sales of Beyond Burgers are projected to makeup 40% of all burger sales.i. Illustrate and explain the effect of the increased use of Beyond Burgers on (i) theburger patties market and (ii) the vegan market.arrow_forwardQuestion 10 Which of the following startements about network externalities is CORRECT? Air pollution is an example of a network externality. For a good with network externalities, the number of people who are willing to buy a unit of the good is uniquely determined by the price. Network externalities are always positive. The manufacturer of a new good with network externalities might give away a free version of the good. For a good with network externalities, one person's valuation of the good is always increasing in the number of other people using the good.arrow_forwardConsider the market for CD players, illustrated in the figure to the right.

An English auction was used. One night, a television producer grabbed the nose for $1,400, while the next night it fetched $1,600. On other nights it sold for $3,000 and $900.

(Sushi is a type of food popularized in Japan. It consists of cooked rice combined with raw fish or other seafood.) People in this town have always liked large portions of grilled meat such as steak, so initially they are reluctant to try a restaurant that serves tiny portions of raw fish. Soon, however, an influential health report warns of the dangers of eating grilled meat and suggests that people should eat more fish, especially raw fish. Explain the effect of this health report on the market for sushi in this town in the short run. Specifically, explain what happens to the price of sushi, the number of sushi restaurants, and the profits of sushi restaurants. Explain the effect of this health report on the sushi market in this town in the long run.

- When a company offers a new product or service, they estimate how much of that product or service people will want at different prices. This is referred to as the product or service demand. As the price of a product or service increases, the demand usually decreases, and this drives the price down. Companies use the estimated demand to determine how much of a product or service they are willing to supply at different prices. As the price of a product or service increases, companies are willing to supply more of it because they will earn more money. If you graph the demand and the supply curves on the same xy-plane, they will sometimes intersect at the point where the price and the supply are in equilibrium. Consider the scenario below. Yaseen is a local artist who wants to increase the amount of money she earns every month by selling at-home painting kits. These kits will include a photograph of the finished painting, a link and password to Yaseen’s YouTube channel where she will…arrow_forwardThe first sushi restaurant opens in a town.

Each week, Omar puts either apples or bananas on sale. He is trying to figure out which fruit he should put on sale this week. Omar gets all of his business from people who walk by his fruit shop and stop in. He performs some market research and asks 800 different people if they would purchase apples, bananas, or no fruit if they walked by and apples were on sale. He does the same for bananas being on sale. This week a total of 400 people will walk by Omar's Fruit Shop. The following table shows the profit for each type of fruit depending on which fruit Omar puts on sale: Apples on sale Bananas on sale Profit from apples $0.25 $0.40 Profit from bananas $0.45 $0.30 The following table shows the results from his market research.
