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.
give me correct answer with proper explanation
A network effect, or network externality, exists when: Group of answer choices a firm
’
s average total cost rises continuously over the entire ran the customers of one business overlap with those of another competing business. the costs of resources for an industry rises as the number of sellers in an industry expands. the value of a product or service to each consumer increases as the number of users expands.
Styles
In an auction, potential buyers compete for a good by submitting bids. Adam Gallinsky, a social scientist from
NWU, compared eBay auctions in which the same good was sold. He found on average that, the higher the
number of bidders the higher the sales price. For example, in two separate auctions of identical IPods, the one
with the higher number of bidders brought the higher sales price. According to Gallinsky, this explains why
smart sellers set absurdly low opening prices (the lowest price the seller will accept), such as 1 cent for a new
IPod. Use the concept of consumer and producer surplus to explain this reasoning.

- How does a positive network effect influence the private and social demand curves for a network good? Private demand shifts right, and social demand shifts left. Private demand shifts left, and social demand shifts right. Both private demand and social demand shift left.

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.)

- Complementary goods are goods that are closely related. Choose the example below that best describes complementary goods. Sally planned to eat lunch at McDonald's, but it was closed. She decided to go to Wendy's for lunch instead. Tom went to the store to buy groceries. He had cherry soda on his list, but he decided to buy lemon-lime soda instead. The lemon-lime soda was on sale, so it was a better deal. In the spring, the demand for tennis rackets goes up. This causes the potential demand of tennis balls to also go up. December is the most popular month of the year to bake cookies. This causes the demand for butter to go up and the cost of margarine to go down.arrow_forwardThe table details the total utility that J.J. gets from going to see basketball and hockey games during a month. J.J. had $120 to spend. Calculate the marginal utility and the marginal utility per dollar spent for both basketball and hockey given that the price is $20 and $30 respectively. Based on your calculations: how many basketball games would he attend? how many hockey games would he attend?arrow_forwardThe rules of politics are not always the same as the rules of economics. In discussions about setting budgets for government agencies, there is a strategy called “closing the Washington Monument.” When an agency faces the unwelcome prospect of a budget cut, it may decide to close a high-visibility attraction enjoyed by many people (like the Washington Monument). Explain in terms of diminishing marginal utility why the Washington Monument strategy is so misleading. Hint: If you are really trying to make the best of a budget cut, should you cut the items in your budget with the highest marginal utility or the lowest marginal utility? Does the Washington Monument strategy cut the items with the highest marginal utility or the lowest marginal utility?arrow_forward
- Anon is a graduate student at Lock Haven University studying human behavior. Three subjects, Felicity, Terrance, and Lola, listed their utility for pineapple and watermelon. Anon believes he will be able to tell which subject likes pineapple the most by referring to the levels of utility each one reported. His adviser, Dr. Util, tells him his research is flawed. Explain why Dr. Util feels this way.arrow_forwardHow do your total and marginal utility change as you stay at home watching the same TV show (not necessarily the same episode) alone all day?arrow_forwardNathan and Joe are shopping for video games. The demand function of George for Track and field games is Q = 40 - 4P, and Georgia’s demand function is Q = 36 - 3P. What will their combined demand be if the price is $2? $10? If we add George and Georgia’s demand functions, we get: At $2 a game, both George and Georgia’s will have positive demand for field games, and so we can use the combined equation to getAt $10 a game, however, George’s demand function gives negative demand, which we know means he just has 0 demand for field games. In this case, we ignore George's function, and just use Georgia’s to figure out their combined demand, since using the combined function would give the wrong answer.arrow_forward
