Suppose the board of directors of Hyvee can either pay $400 or $200 per day for a manager. If the manager behaves well, Hyvee will earn $800 in profits per day, and if he does not behave well, Hyvee will only earn $400 in profits per day. Hyvee must offer a wage to the manager before observing his behavior. Behaving well costs the manager $200 per day, while exerting the effort to behave badly only costs the manager $100. What is the equilibrium outcome?
Board pays $200, manager behaves badly
Following up on the previous problem, now the board of directors monitors the behavior of the manager. If they pay the manager $400, but he still behaves badly, the manager will receive a fine of $300 for bad performance. At the same time, if the manager behaves well, but the board of directors only pays him $200, the manager will gain a bonus of $250. What is the equilibrium outcome under these new conditions?
Board pays $400, manager behaves well

Supply/Demand Shifts: Consumers get news that a new iPhone prototype was found in a bar near Sunnyvale, CA. They expect this means a new iPhone model will be available soon. How does this impact the market for the current iPhone model
Graph should show a shift of the demand curve to the left. This will lead to both price and quantity declining at the new equilibrium.
Supply/Demand: A hurricane shuts down oil refineries on the gulf coast. It also floods the 4th largest city in America, making its roads impassable and driving impossible. What impact do these events have on the market for gasoline?
Graph should show shifts of both the supply and demand curves to the left. This will lead to a decrease in the equilibrium quantity, however because the supply shift will put upward pressure on price, and the demand shift will put downward pressure on price, it is not possible to say what will happen to the equilibrium price without knowing the magnitude of the supply/demand curve shifts.
Supply/Demand: Three new Cross Fit gyms open up in Vermillion, SD. At the same time, several news outlets run stories highlighting the increasing number of injuries associated with cross fit - while also alerting consumers to the availability of a new workout facility called Parallel Fit, which is like Cross Fit but much safer. How does this impact the market for Cross Fit memberships?
Graph should show the demand curve shifting to the left, while the supply curve should shift to the right. This will lead to a decrease in the equilibrium price, however because the supply shift will put upward pressure on quantity, and the demand shift will put downward pressure on quantity, it is not possible to say what will happen to the equilibrium quantity demanded without knowing the magnitude of the supply/demand curve shifts.
Supply/Demand Shift: The patent for Xerac, a drug that gives people x-ray vision, expires. This allows many firms to start manufacturing the same drug. What impact does this have on the market for Xerac?

Calculate the value of profits for a representative firm in the long run?
In a perfectly competitive market, long-run profits are always zero
Suppose a perfectly competitive market for hot-dog stands in New York City changes when gourmet, discount, and ethnic hot-dog retailers show up, making each cart slightly different. With the inclusion of the new vendors, hot-dog stand owners are now engaged in monopolistic competition. If hot dogs from different stands are imperfect substitutes and there are numerous carts in the city, compare the producer and consumer surplus and total social welfare before and after the change
In the short run, moving from perfect competition to a monopolistically competitive market will reduce social welfare because the monopolistically competitive firms will maximize profits by producing less than the efficient quantity. This will create a deadweight loss. Consumer surplus will decrease because the monopolistically competitive firms will be able to charge a higher price than the competitive firms could charge. Producer surplus should increase compared to perfect competition because vendors are selling versions of hot dogs for which other types are imperfect substitutes. Consumers will have preferences between types of hot dogs, which will allow for price differentials.
You are bidding in an auction for a certified, used tractor. You determine that the economic profit you can make from the tractor is $80,000. You do not care about any risk or uncertainty in your estimate of the economic profit. Other bidders have their own valuations of the tractor, which depend on their unique uses for it. If the auction is a sealed-bid first-price auction, is your bid more than, less than, or equal to $80,000? Explain your answer.
In this case it is optimal to bid just below your valuation of $80,000 in a sealed-bid first-price auction. If you bid your value, you gain no surplus - which is just as good as not winning the auction. Offering a price just below your value will offer the promise that no one else will bid higher than you and you will get the item at a price below your value - locking in positive profits.

If the auction is a Dutch auction, is your maximum bid more than, less than, or equal to $80,000? Explain your answer.
In this case it is optimal to bid just below your valuation of $80,000 in an dutch auction. If the item is still available and you immediately bid your value, you gain no surplus with certainty. Waiting until the price falls below your value will offer the promise that no one else will bid and you will get the item at a price below your value - locking in positive profits

In this case it is optimal to bid your valuation of $80,000 in a sealed-bid second-price auction. If you bid your value, you may win, but only pay what the next highest bidder offered - which guarantees a profit. Bidding above your value offers the possibility that someone else will bid below your bid but above your value, ensuring your earn negative profits. Because you only pay what the second highest bidder offers, there is no value in bids higher than your value because if doing so was necessary for you to win the auction, it would also ensure you earned negative profits.

Matt and Kendrick are DJs who each want to play a huge concert for their group of friends on New Year's Day. Matt knows that Kendrick wants to have his own concert, and Kendrick knows that Matt wants his own concert. The problem is that if they both have a concert at the same time, half their friends will go to each, and neither of them wants a half-full concert. The benefit to either Matt or Kendrick of not playing a concert is 0. If one DJ has a concert while the other does not, the DJ at the turntables gets a benefit of 10, while the DJ who is not playing gets a payoff of -5. If they both play at the same time, each gets a payoff of -10. What is the Nash equilibrium of this game? Matt DJs and Kendrick DJs Matt DJs and Kendrick does not DJ Kendrick DJs and Matt does not DJ Neither DJ plays

Explain the short-run and long-run difficulties that airlines would have in raising ticket prices when jet fuel prices rise.
Multiple responses are acceptable - could reference the fact that fuel prices fluctuate frequently, while a significant fraction of tickets are purchased weeks ahead of travel.
Airline industry experts generally believe that air travel is a very competitive market. As a result, it is assumed that it is difficult, if not impossible, for airlines to pass on higher jet fuel prices to passengers by raising ticket prices What attributes are present in the air travel market that are consistent with perfect competition?
Nationally there are a large number of buyers and sellers, however this may not be true locally. The product is highly regulated and thus a trip in coach on most airlines is very standardized (though it is branded). Firms are free to enter/exit and frequently do - there are no barriers to entry.

The firm is maximizing profit.
Why does the marginal product of labor eventually decline as more labor is used with another fixed input?
The labor will have, on average, fewer units of the other inputs to combine with and the increases to total output obtained from more labor will decrease.
Why is a winner's curse less likely in auctions for independent private value items than in auctions for common value or correlated value items?
The prospect of suffering the winner's curse increases if a firm has less information than its competitors and/or if there is significant uncertainty about the true value of the item being auctioned. With independent private values, a firm is less likely to under or overvalue an item because they have the best information about how they will use the item. With an item that has a common value, everyone bidding on the item gets the same value when they win - even if they don't know what that value is. As a result, when more people enter an auction for a good with a common value, the liklihood that some of them know more than you do about the true value of the item increases. Thus, it is less likely you will suffer the winner's curse in an auction for a good with an independent private value because it is more likely that you know the true value of the item relative to an auction where the good has a common value among all bidders.

Explain why automobile manufacturers produce their own engines but purchase mirrors from independent suppliers.
This could be the result of multiple factors, the two most likely being THE HOLDUP PROBLEM and an increase in information and control. Engines are a central and essential component to an automobile, while a mirror is an accessory. If there are problems with the delivery of the engines to the automobile assembly line, it can be very costly. Engines that are not powerful enough can make a car useless, engines that vibrate 2 too much can cause other parts to loosen or break, and engines of the wrong shape may not fit well within the frame. Furthermore, a failure for this part to be delivered on time will prevent the assembly line from proceeding because it would be impossible to drive a car off the line without an engine. Mirrors, on the other hand, are not essential for moving the vehicle down the assembly line and can easily be affixed to the body at a later date. There is no potential holdup if mirrors do not arrive, and because they are not a specialized technology they can easily be sourced from multiple vendors - preventing trading partners up the supply chain from leveraging better terms from the automakers. While it may be helpful for the car designers and engine designers to work collaboratively, it is likely that the design for the mirror can be easily arrived at by a single team since it is unlikely to impact any other car components.
You are bidding in an auction for a certified, used tractor. You determine that the economic profit you can make from the tractor is $80,000. You do not care about any risk or uncertainty in your estimate of the economic profit. Other bidders have their own valuations of the tractor, which depend on their unique uses for it. If the auction is an English auction, is your maximum bid more than, less than, or equal to $80,000? Explain your answer.
This prompt suggests that the tractor is valued independently by the bidders who have different uses for the farm implement. In this case it is optimal to bid up to the valuation of $80,000 in an english auction. You know your value, so you only need to bid until all the other competitors drop out of the auction. If you drop out earlier you miss a chance to possibly profit from a winning bid of less than your value. If the bidding arrives at your valuation of $80,000, you can stop and know that if you continued to bid you would might win, but any bid above your value would bring you negative surplus

Perhaps the most popular feature of the Affordable Care and Patient Protection Act is a provision that prohibits insurance companies from denying coverage or raising premiums based on a preexisting condition. Among health-care wonks, this is known as "guaranteed issue." Another popular feature of that law are the subsidies offered by the government that help make insurance premiums affordable to Americans of every income bracket. Those popular provisions of the law commonly referred to as 'Obamacare' are paired with another much less popular provision: that every American is required to maintain qualified health insurance coverage. Many legislators have signaled their desire to do away with this unpopular provision, while maintaining the well-liked guaranteed issue provision and assuring voters that premiums will remain reasonably priced. Using what you have learned about adverse selection in this module, explain why this approach is unlikely to succeed.
Two words: death spiral. If firms have to offer policies to everyone, they need to price those policies to cover all of the possible losses they will suffer as a result of insuring everyone. Because the premium each person pays reflects the average loss among all insured persons, necessarily some people will pay more for insurance than they are likely to use and others will pay less than they are likely to use. Naturally, some of the healthy people who are paying for more health insurance than they are using, they might opt out and elect to just come back and get insurance once they are sick - and firms would have to let them. As a result, the pool of people currently insured would only contain people using high levels of healthcare services. This will force insurance companies to raise prices, which will cause more of the relatively healthier insurance plan participants to cancel coverage, which will further raise premiums...and so on. If this plan were to be taken to the logical conclusion, health insurance would be incredibly expensive eventually nobody would be able to afford it.

The market for birthday clowns is hit-and/or-miss. 50% of clowns will just scare the kids - but hey, at least they are occupied doing something? On the other hand, good clowns are awesome and the kids will make memories for a lifetime. A parent would pay $100 for a bad (scary) clown to work their child's birthday party and a bad clown really has no better employment options, and so will accept anything more than $50. Parents would happily pay up to $200 for a good clown, but good clowns know they have a special talent and will not work for anything less than $100. If parents pay clowns up front and cannot tell a good clown from a bad clown until after it is too late, which answer below describes a possible equilibrium in the market for birthday clowns?
both good and bad clowns are hired and they are paid $100 no matter which type they are
