Which of the following startements about network externalities is CORRECT? 00 00 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.

- Explain the difference between a positive and a negative network externality. A network externality for a good is positive if O A. the substitution effect of a price change is larger than the income effect, but a network externality is negative if the income effect is larger than the substitution effect. B. consumption by others decreases a typical consumer's marginal utility from consuming the good, but a network extemality is negative if consumption by others increases a typical consumer's marginal utility from the good. c. the price is lower the more people own it, but a network externality is negative if the price is lower the fewer people own it. D. the quantity demanded is higher the more people own it, but a network externality is negative if the quantity demanded is lower the more people own it. O E. it has a complement, but a network effect is negative if it has a substitute. Give an example of each. An example of a positive network externality is the dermand for A. a work of…Consider a local fast food restaurant.

- 1. Hatfield and McCoy hate each other. The only good they both consume WH W2 40 Mand McCoy's is whiskey. Hatfield's utility function is UH utility function is UM = WM-W, where WHI is Hatfield's consumption 40' Η of whisky and WM is McCoy's consumption of whiskey. The sheriff has confiscated a total of 60 litres of whiskey which he could give back to them or throw in the creek. Say that the Sheriff wants them both to be as well off as possible and weighs their "happiness" equally. How much whiskey should the sheriff give to each of them? Should he throw any whiskey in the creek; if so how much? =Assume you have your car broken down just before the weekend. You value your weekend trip as muchas v and if you have to stay home you get the zero utility. There are two dealerships in your town. Atthe beginning of the day they simultaneously choose a price for repair. Dealers know that when you cometo one of them and observe the price, you can always call to another dealer to make an inquiry about hisprice. The call is costless. The other dealer, however, can be occupied for this day. Assume, this happenswith probability which is a common knowledge (but the dealers do not know whether the other dealer isoccupied or not). Assume zero repair cost for the dealer and find a symmetric equilibrium of the game.What can you do if there are too many passengers for your car? O Offer to take half the party, or cancel at no charge Take them all anyway O Cancel and.complain to Uber O None of the above
- 11:55 The table below shows the per unit prices and marginal utility for the last unit of waffles and donuts that Luke purchased. Waffles Price per unit Marginal utility Luke spent all of his allocated budget on waffles and donuts. To maximize his utility, Luke should purchase O fewer of both goods O fewer waffles and more donuts O equal amounts of both goods O more both goods O more waffles and fewer donuts $25 Donuts 50 $10 50Ari intends to purchase a new car and has narrowed it down to a Dodge Ram truck or a Toyota Camry. A Dodge Ram truck costs $55000 while a Toyota Camry costs $20000. The utility that Ari will get from Dodge Ram truck is 12500 while Toyota Camry will generate a utility of 2500. Note: A purchase generating utility tells us the marginal utility of the good. What is the Marginal Utility per Dollar for Dodge Ram truck? What is the Marginal Utility per Dollar for Toyota Camry? Will Ari be better off buying a Dodge Ram truck or a Toyota Camry? ODodge Ram truck OToyota Camry AJeremy is deeply in love with Jasmine. Jasmine lives where cell phone coverage is poor, so he can either call her on the land-line phone for five cents per minute or he can drive to see her, at a round—trip cost of 2 in gasoline money. He has a total of 10 per week to spend on staying in touch. To make his preferred choice, Jeremy uses a handy utilimometer that measures his total utility from personal visits and from phone minutes. Using the values in Table 6.6, figure out the points 011 Jeremys consumption choice budget constraint (it may be helpful to do a sketch) and identify his utility-maximizing point.
- Praxilla, who lived in ancient Greece, derives utility from reading poems and from eating cucumbers. Praxilla gets 30 units of marginal utility from her first poem 27 units of marginal utility from her second poem 24 units of marginal utility from her third poem, and so on, with marginal utility declining by three units for each additional poem. Praxilla gets six units of marginal utility for each of her next three cucumbers consumed, five units of marginal utility for each of her next three cucumbers consumed, four units of marginal utility for each of the following three cucumbers consumed, and so on, with marginal utility declining by one for every three cucumber consumed. A poem costs three bronze coins hut a cucumber costs only one bronze coin. Praxilla has 18 bronze coins. Sketch Praxillas budget set between poems and cucumbers, placing poems on the vertical axis and cucumbers on the horizontal axis. Start off with the choice of zero poems and 18 cucumbers, and calculate the changes in marginal utility of moving along the budget line to the next choice of one poem and 15 cucumbers. Using this step-by-step process based on marginal utility, create a table and identify Praxillas utility—maximizing choice. Compare the marginal utility of the two goods and the relative prices at the optimal choice to see if the expected relationship holds. Hint: Label the table columns: 1) Choice, 2} Marginal Gain from More Poems, 3) Marginal Loss from Fewer Cucumbers, 4) Overall Gain or Loss, 5) Is the previous choice Optimal? Label the table rows: 1) 0 Poems and 18 Cucumbers, 2) 1 Poem and 15 cucumbers, 3) 2 Poems and 12 cucumbers, 4) 3 Poems and 9 Cucumbers, 5) 4 Poems and 6 cucumbers 6) 5 Poems and 3 Cucumbers, 7) 6 Poems and 0 Cucumbers.You like to eat apples and carrots.
