Chapter 5, Problem 5.1.10PA
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 demand for drinking and the private and

Shell has over 13,000 gas stations in the United States. In addition to gasoline, the gas stations also sell convenience items, such as snacks, non-alcoholic beverages, wine, beer, and hot food. Suppose you work for a gas station and your boss asks you to develop a pricing strategy for bottled local wine. The demand function is ? = 100 – 4?, where ? is the monthly quantity demanded of the bottled wine and ? is the price of the bottled wine. The marginal cost per bottle of wine is $5. Complete the following tasks:
1) (Calculating) In the worksheet “Q2 Calculations” of the provided Excel file, enter formulas in columns B-D to calculate Q (quantity demanded), MC (marginal cost), and MR (marginal revenue). Please round your results to one decimal place. Note that the inverse demand function is ? = 25 − 0.25? and that the MR function can be derived from the inverse demand function using the formula introduced in Module 5. You may find it helpful to review the Excel file for Chapter 11.
The Camera Shop sells two popular models of digital SLR cameras (Camera A Price: 230, Camera B Price: 310). The sales of these products are not independent of each other, but rather if the price of one increase, the sales of the other will increase. In economics, these two camera models are called substitutable products. The store wishes to establish a pricing policy to maximize revenue from these products. A study of price and sales data shows the following relationships between the quantity sold (N) and prices (P) of each model:
NA = 192 - 0.5PA + 0.25PB
NB = 305 + 0.08PA - 0.6PB
Construct a model for the total revenue and implement it on a spreadsheet. Develop a two-way data table to estimate the optimal prices for each product in order to maximize the total revenue. Vary each price from $250 to $500 in increments of $10.
Max profit occurs at Camera A price of $______.
Max profit occurs at Camera B price of $______.
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,

- Page 2 3. In a study ("Price elasticity in the performing arts" by Kolhede, Gomez-Arias & Maximova 2023) researchers surveyed residents in one California county. They used responses to 28 questions about motivations to attend events to develop motivation factors and then clustered respondents into 3 segments based on their motivations. The authors estimated the performing arts event demand for each segment and calculated the demand elasticities at different prices and reported the following: Elasticities for the 3 segments with a $20 Admission Price were 0.317, 0.343, and 0.317 Elasticities for the 3 segments with a $60 Admission Price were 2.608, 3.269, and 2.590 Unitary Elasticity was at $41.50, $39.18, and $41.58 for the 3 segments Assume that the cost of event production is fixed (not related to attendance).

- Question 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_forwardAccording to a researcher at the FDA, vegan foods are “the way if the future”.

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. Why did the value fluctuate substantially from night to night? The value of the nose fluctuated from night to night because the bidders have private values for the auction item.

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.
