Pfizer and a competitor, Astra-Zeneca, are considering developing a new drug for a particular illness at the same time. The illness is relatively rare but the fixed cost of production is very high. In particular, the forecast demand for such a drug is insufficient to cover both firms’ costs. Analyse the interaction between the two firms using game theory. Present a payoff matrix to model the situation and analyse it for Nash equilibrium. What can either of these firms do to make their best, most- preferred outcome more likely?
Consider a situation where two firms, 1 and 2, compete by choosing prices simultaneously. They can either compete (charge a low price) or cooperate (collude, charging a high price). The firms play this competition game repeatedly and indefinitely, using a grim trigger strategy to incentivize cooperation. They use the same interest rate, i , to discount future payoffs. Payoffs are $4,050 when both firms cooperate and $3,600 when they compete. If one firm charge a low price while the other charges a high price, the firm charging the low price gets $7,200, and the other gets zero. Which of the following statements is correct?(a) For any i < 1/7 the firms will cooperate(b) For any i > 1/8 the firms will cooperate(c) For i = 1/9 the firms will be indifferent between cooperating or competing(d) There is no way to sustain cooperation in this scenario
Alcoa and Kaiser, duopolists in the market for primary aluminum ingot, choose prices of their 500 foot rolls of sheet aluminum on the first day of the month. The following payoff table shows their monthly payoffs resulting from the pricing decisions they can make.
Suppose Alcoa and Kaiser repeat their pricing decision on the first day of every month. Suppose they have been cooperating for the past few months, but now the manager at Kaiser is trying to decide whether to cheat or to continue cooperating. Kaiser’s manager believes Kaiser can get away with cheating for two months, but he also believes that Kaiser would be punished for the next two months after cheating. After punishment, Kaiser’s manager expects the two firms would return to cooperation. Kaiser’s manager ignores the time-value of money and does not discount future benefits or costs.
Will Kaiser cooperate or cheat? Explain.

- Olivia is thinking about opening a new bakery (the entrant). There is already a bakery open in her neighborhood (the incumbent), and the owner of the incumbent bakery makes it clear that if Olivia enters the market, they will cut their prices in an attempt to drive the new bakery out of business. Based on the payoff matrix below, is the incumbent’s threat credible? That is, if Olivia opens a new bakery, will the incumbent actually lower their prices? Note: the entrant chooses the row, the incumbent chooses the column High price Low price Enter 1, 2 -1, 1 Don’t enter 0, 10 0, 1 a. Yes, the threat is credible b. No, the threat is not crediblearrow_forwardThere are two firms in an industry, Firm A and Firm B. If firm A and firm B both advertise, they each will earn $5 million in profits. If neither firm advertises, they will each earn $10 million in profits. However, if one firm advertises and the other does not, the firm that advertises will earn $15 million and the non-advertising firm will earn $1 million. List all Nash equilibrium to this game. Both firms advertise Firm A advertises and Firm B does not Firm B advertises and Firm B does not Neither firm advertises No Nash equilbrium existsarrow_forwardConsider the following entry-deterrence game. A potential entrant has two strategies, “Enter” or “Stay Out”. An incumbent firm can either Price Low or Price High, depending on whether they want to try to fight or accommodate the entrant. (The Price Low option could be a limit price, for example). Suppose if the entrant Enters and the incumbent Prices Low, both firms lose $-1M. If the entrant enters and the incumbent Prices High, each firm earns $2M. If the Entrant doesn’t enter, the incumbent earns $4M and the entrant earns $0. a)Using the concept of Nash Equilibrium, what are the predicted strategies and profits? Set up a game box or tree and explain your reasoning. b) Give an example of a different profit outcome that would lead to a different Nash Equilibrium. (From this, you can see that sometimes deterrence is effective and sometimes it isn’t, depending on the profits).arrow_forward
- To advertise or not to advertise Suppose that Creamland and Dairy King are the only two firms that sell ice cream. The following payoff matrix shows the profit (in millions of dollars) each company will earn depending on whether or not it advertises: Dairy King Advertise Doesn't Advertise Creamland Advertise 10, 10 18, 2 Doesn't Advertise 2, 18 11, 11 For example, the upper right cell shows that if Creamland advertises and Dairy King doesn't advertise, Creamland will make a profit of $18 million, and Dairy King will make a profit of $2 million. Assume this is a simultaneous game and that Creamland and Dairy King are both profit-maximizing firms. If Creamland decides to advertise, it will earn a profit of _________ million if Dairy King advertises and a profit of ________ million if Dairy King does not advertise. If Creamland decides not to advertise, it will earn a profit of __________ million if Dairy King advertises and a profit of _________…arrow_forwardSynergy and Dynaco are the only two firms in a specific high-tech industry. They face the following payoff matrix as they decide upon the size of their research budget: Synergy's Decision Large Budget Small Budget Dynaco's Decision Large Budget $20 million, $25 million $15 million, $0 Small Budget $0, $60 million $25 million, $30 million If Synergy believes Dynaco will go with a large budget, it will choose a budget. If Synergy believes Dynaco will go with a small budget, it will choose a budget. Therefore, Synergy a dominant strategy. If Dynaco believes Synergy will go with a large budget, it will choose a budget. If Dynaco believes Synergy will go with a small budget, it will choose a budget. Therefore, Dynaco a dominant strategy. True or False: There is a Nash equilibrium for this scenario. (Hint: Look closely at the definition of Nash equilibrium.)

Suppose that each company can charge either a high price for tickets or a low price. First, American Airlines will choose the price level. Following this, Braniff Airways will observe its competitor’s decision and choose the price level for its tickets. If both of the companies choose High, they earn $25,000 each. If they both choose Low, they earn $18,000 each. If the companies choose different levels of prices, the one choosing the high price will earn $15,000 and the one choosing Low will earn $30,000. a) Draw the game three. b) Solve the game by using backwards induction. c) If Braniff Airlines makes a promise to choose High if American Airlines chooses High, should American Airlines trust this promise?

- Collusive outcome versus Nash equilibrium Consider a remote town in which two restaurants, All-You-Can-Eat Café and GoodGrub Diner, operate in a duopoly. Both restaurants disregard health and safety regulations, but they continue to have customers because they are the only restaurants within 80 miles of town. Both restaurants know that if they clean up, they will attract more customers, but this also means that they will have to pay workers to do the cleaning. If neither restaurant cleans, each will earn $14,000; alternatively, if they both hire workers to clean, each will earn only $11,000. However, if one cleans and the other doesn't, more customers will choose the cleaner restaurant; the cleaner restaurant will make $18,000, and the other restaurant will make only $6,000. Complete the following payoff matrix using the information just given. (Note: All-You-Can-Eat Café and GoodGrub Diner are both profit-maximizing firms.)
