The French autoroute network is composed of toll motorways with entrances marked as such. A motorist entering the network obtains a ticket from a toll booth and pays a toll when leaving the motorway. Given the number of vehicles traveling these routes, congestion at both entrances and exits is common. Suppose that four groups, each of 50 motorists, use an autoroute. The price each group is willing to pay, v, differs among groups and falls as the amount of congestion, c, increases in the following way: vij = vi max-cj; i, j = 0,..., 3, where vi max = 0.4-0.1 * i euros per kilometer is the maximum group i is willing to pay to use the motorway and cj = 0.06 * j euros per kilometer is the loss in value as more groups use it. The marginal cost of using the autoroute, not including the marginal cost of congestion, is zero. a. If the toll charged for using the autoroute equals a motorist's marginal private cost-the price in a competitive market-how many vehicles per minute will use it? Which groups will use it?

Suppose that a study of changes in admission prices reveals that when the price of admissionto the museum increases by 10%, adults reduce their ticket purchases by 10%, senior citizensreduce their ticket purchases by 20%, college students reduce their ticket purchases by 25%,and children reduce their ticket purchases by 30%. If the cost of having a person visit themuseum is the same regardless of whether the person is an adult, senior citizen, collegestudent, or child, which of the following pricing schemes is the most likely to be used by themuseum and why? Group of answer choices The museum will set one price of $12 for everyone because that is the most fair. $8 for children, $10 for college students, $12 for senior citizens, and $15 for adultsbecause the museum can earn higher profits by charging the lowest price to those with theleast elastic demand and the highest price to those with the most elastic demand. $15 for children, $12 for college students, $10 for senior citizens,…
A firm is considering building a two-way network that links 12 users. The cost of building the network is $10,000. a. How many potential connection services does this network provide? b. If each user is willing to pay $150 to connect to the network, will the firm profit by building the network? c. If each user is willing to pay an average of $12 for each potential connection service provided by the network, will the firm profit by building the network? d. What happens to the number of potential connection services if one additional user joins the network?
Which of the following statements is correct? Select one: a.In models of network goods with positive externalities, no consumption is always an equilibrium. b. The equilibrium in the hotelling model when both firms have the same location is for the firms to set their prices equal to their (constant) marginal cost even if their marginal costs are different. c. If all firms start wiht the same techonology, under both minor and drastic innovations the inovator firm is only one firm producing after the innovation. d. The Schumpeter hypothesis establishes that competitive firms have higher capacity to produce R&D than monopolies.
In Salop’s model of entry deterrence, the unconstrained monopoly earns profits (in present value terms) equal to some amount v0. Suppose v0 = 100. If entry were to occur, the two firms would share the market, each earning v1.(A) Why do we expect 2 v1 to be less than 100 ? (B) The incumbent monopoly can prevent entry by expending a fixed and irreversible amount C that the entrant must match. What conditions on the size of C will both successfully prevent entry, and equally importantly, result in greater profit for the incumbent than by allowing entry?
MySpace, Facebook, email, and collaborative sites for both work and leisure are a norm on the net these days. But did you know all of the content you post on many of these sites immediately become partially owned by the sites themselves? And, taking items away by deleting them never really gets rid of them. In fact, in Groundswell by Bernoff and Li, they state that trying to take something off the Internet that you have posted is like trying to remove pee from a pool. Scott McNealy, founder of Sun Microsystems, perhaps sums it up best, “You have zero privacy anyway. Get over it.â€ Keep in mind that technology is everywhere all the time (ubiquitous) because of the onset of smartphones, and other mobile devices. You have a 21st century phenomenon. But, is what Scott McNealy said true? Cite and explain examples that support and argue against this statement.
(A) Suppose that the two firms merge. Write down the profit function of the merged firm. Calculate the profit maximizing level of output, the amount of pollution for the merged firm, and its profit. Is the merger Pareto improvement? Why or why not? (B) Suppose that the merger is forbidden by the government. Instead, now the fishery has the property right to water. In other words, anybody who wants to pollute the water needs to buy a pollution right from the fishery. Let the price of the pollution right be Px. Write down the steel mill’s new profit function and the fishery’s new profit function. (C) Calculate the profit maximizing level of output for each firm, the amount of pollution, and the price of pollution right. please, please answer the three questions together..
JetBlue and Delta are the only two major airlines with regularly scheduled service between New York and Nantucket. There are 900 potential passengers every week, each of whom is willing to pay up to $400 for a ticket. Since the two airlines provide an essentially identical (bad) service, customers simply prefer to buy from the cheaper one. (If they charge the same price, then they will split the market equally.) Each airline can transport at most 1200 passengers each week. You can safely assume that each airline spends literal peanuts (i.e., zero) serving passengers; however, each passenger displaces air cargo that is worth $160 in profits to the carriers. Suppose that each airline takes a short-run perspective and only wants to maximize each week's profits, and that neither one would consider shutting down the route in the foreseeable future. (a) What is the appropriate economic model to study price competition in this market? (b) If you use Nash equilibrium to make a prediction, what…

Imagine that two firms in two different countries want to bring a new product tomarket. Due to economies of scale, if both firms do this, they will both lose £50million. But if only one firm does this, it will gain £300 million.(a) What is the best strategy for firm A, if firm B has not yet entered the market, andwhy?(b) Illustrate this with a game theory diagram, showing appropriate payouts.(c) What is the welfare-maximising strategy for a government, and why?
. When Chinese automakers began exporting cars, rather thanfocusing on developed nations in the West, they shippedautos to emerging markets in countries such as Algeria, Russia,Chile, and South Africa. In these markets, even used vehiclesfrom multinational manufacturers are relatively scarce—andrelatively expensive. The Chinese automakers, who prioritizelow cost rather than design or even safety, applied a penetration-pricing strategy. A woman in Santiago, Chile, who boughta new Chery S21 explained, “The price factor is fairly decisive.I paid $5,500 new and full. Toyota with similar features costsaround $12,000.” Why do you think Chinese automakerschose that pricing strategy? Do you think it was successful?As Chinese regulators pressure these manufacturers to maketheir cars safer, do you think they will be able to keep theirprices low compared with those of the international automakers? Why or why not?26
The magazine Science 84 planned to announce a contest in which anyonecould submit a request for either $20 or $100. If fewer than 20% of the submissions requested $100, then everybody would receive what they requested. If 20% or more asked for $100, then everybody would get nothing. Although the magazine wound up not running the contest, because Lloyds of London was unwilling to insure against losses, we can still analyze what equilibrium would predict. Suppose 100,000 people might participate in the contest, and assume that payoffs are measured in money.a. Assume that every possible participant submits a request for either $20or $100. Find a Nash equilibrium.b. Now suppose that a request form comes only with the purchase of Science 84 and that the magazine costs $21.95. Then each person’s strategy set has three elements: do not buy the magazine, buy the magazine and submit a request for $20, and buy the magazine andsubmit a request for $100. Suppose zero value is attached to…
