Module 12.6 (look at camera roll) If Ferris sets QF = 50, what is Rasa's best response? Rasa will setQR = 50.QR = 0. If Ferris sets QF = 135, what is Rasa's best response? Rasa will setQR = 0.QR = 50. Taking Rasa's best responses into account, what is Ferris's best action? Ferris will setQF = 50.QF = 135.

Choosing 50 is the answer bc If Ferris Corp. sets its production levels to QF = 50, then Rasa stands to earn a profit of $2,500 by entering the market (setting QR = 50) and earns nothing by staying out of the market (setting (QR = 0). In this case, entering the market is Rasa's best response. If Ferris tries to deter Rasa's entry by flooding the market (setting QF = 135), then Rasa will lose $1,750 by entering the market (setting QR = 50) but will avoid any profits or losses by staying out of the market (setting QR = 0). In this case, staying out of the market is the best response. Knowing that Rasa will enter the market with a low quantity and will stay out of the market with a high quantity, Ferris can determine the outcome of its own actions. Setting a low quantity (QF = 50) will result in a $2,500 payoff for Ferris, while trying to deter Rasa (setting QF = 135) will result in a payoff of $2,025. Ferris's best action is to set QF = 50. Ferris's method of deterrence is not ineffective, but it proves too costly in terms of foregone profits. Sometimes it is better for incumbent firms to accommodate new entrants than try to deter them.

Module 12.4 Orange and Billsung both produce smartphones and are considering increasing the rates on their data plans. Assume that each firm has complete knowledge of the other's payoff for a given decision. The payoff matrix represents the payoffs to each firm, where Orange values are in bold and Billsung values are in italics. The decision tree assumes Billsung chooses its strategy first. Use this information to complete the statement. (look at camer roll) Billsung will choose to _____ and Orange will _____ rates.

keep current rates and increase bc If Billsung increases rates, Orange would respond by keeping its current rates, which would result in a lower payoff to Billsung ($35 million compared to $45 million). It follows that Billsung will keep the current rates. The result for Billsung is a payoff of $45 million, while that for Orange is $35 million.

Module 11.1 Which statement is not an example of adverse selection? - Relative to all cars with similar observable characteristics, those in the used car market are less reliable. - A person does not buy a car alarm because auto theft is covered in her insurance policy. - Individuals who expect more health problems are more likely to buy generous health insurance policies.

A person who does not buy a car alarm is the correct bc adverse selection is an issue when asymmetric info is involved with one party having more info over the other (ex: used car market leads to low quality cars in market and health insurance) However, this is an example of moral hazard bc not having a car alarm is more risky behavior than one would naturally partake in

Module 11.3 What worsens adverse selection in a dental insurance market where buyers have private information? -Selling only to risk-averse buyers. -Grouping buyers by a risk factor and charging a premium based on risk. -Allowing buyers to opt-in and opt-out of the market at any time they desire. -Requiring that each buyer's premium be based on that specific buyer's costs.

In the prisoner's dilemma, firms could do better if they both did exactly the opposite of what they ultimately choose to do. The prisoner's dilemma is an example of a cooperative equilibrium.

In the prisoner's dilemma, firms could do better if they both did exactly the opposite of what they ultimately choose to do. If they both act naturally they will choose themselves and probably both confess which actually leads to a worse outcome.

Module 12.4 What is backward induction (called "prune the tree method" in the textbook) for solving a game tree? The player starts at the beginning and eliminates all branches that do not take her in a desired direction. The player looks to the possible end results, chooses the desired result, works backward to where the player is, and eliminates all other cells. The player will remove any branches that are associated with losses for the player so that they are not considered. The player looks forward to the final period, highlights out her rival's best responses, then removes the options the rival would not choose.
