Firm 1 has two options: enter a new market (E) or stay out (O). If Firm 1 decides to enter the market, Firm 2, the incumbent, can either fight (F) or accommodate (A). If Firm 2 chooses to fight, Firm 1 can choose to compete with Firm 2 by raising their advertising budget (C) or keep their planned budget the same (NC).The payoffs to Firm 1 and 2 if Firm 1 chooses O are 5 and 4. If Firm 2 chooses A, the payoffs are 3 and 0. The payoffs from E followed by F and NC are 1 and 2. The payoffs from E followed by F and C are x and 1. The parameter x is an integer and x > 1.What is the lowest integer value of x so that Firm 1 will definitely choose E in a subgame perfect equilibrium of this game?Write your answer as an integer (no decimal points).

Solution

The question is asking for the lowest integer value of x that would make Firm 1 choose to enter the market (E) in a subgame perfect equilibrium.

A subgame perfect equilibrium is a refinement of a Nash Equilibrium used in dynamic games. It is a strategy profile that induces a Nash Equilibrium in every subgame of the original game.

Here are the steps to solve this:

  1. First, we need to understand the sequence of the game. Firm 1 has the first move and can choose to either enter (E) or stay out (O). If Firm 1 enters, Firm 2 can choose to fight (F) or accommodate (A). If Firm 2 fights, Firm 1 can choose to compete by raising their advertising budget (C) or keep their planned budget the same (NC).

  2. Next, we look at the payoffs. If Firm 1 chooses to stay out (O), the payoffs are 5 for Firm 1 and 4 for Firm 2. If Firm 1 enters and Firm 2 accommodates (A), the payoffs are 3 for Firm 1 and 0 for Firm 2. If Firm 1 enters, Firm 2 fights, and Firm 1 does not compete (NC), the payoffs are 1 for Firm 1 and 2 for Firm 2. If Firm 1 enters, Firm 2 fights, and Firm 1 competes (C), the payoffs are x for Firm 1 and 1 for Firm 2.

  3. In a subgame perfect equilibrium, Firm 1 will choose to enter (E) if the payoff from entering is greater than the payoff from staying out (O). This means that x (the payoff from E, F, C) must be greater than 5 (the payoff from O).

  4. Since x is an integer and must be greater than 5, the lowest integer value of x that would make Firm 1 choose to enter the market in a subgame perfect equilibrium is 6.

Let's consider if Firm 1 can do better by setting a price higher than thesolution to question (b). The downside of firm 1's setting a higher price isthat it will lose some of the market. The upside is that it will charge moreto any customer it keeps. The next question gets you to work out just howmany customers buy from firm 1 when the prices are 'close'. (c) (10 points) Suppose that prices p1 and p2 are close enough that themarket is split between the two firms. Use expressions (a) and (b)above to find the location of the customer who is exactly indifferentbetween buying from firm 1 and buying from firm 2. Use your answerto argue that, when the market is split, firm 1's demand is given by: D1(p1; p2) = (p2 + t -p1)/2t, We now have all the information we need to calculate firm 1's best responseto each p2. When the market is split, firm 1's profits are given by u1(p1; p2) = (p1 -c)D1(p1,p2) =[p1 (p2 + t + c) -(p1)^2-c(p2+t)]/2t, Notice it follows from expressions (1) and (2), that for intermediate levels of p2, the best response of firm 1 to firm 2 setting some intermediate pricep2 is to set a price p1 that solves max p1[p1 (p2 + t + c) -(p1)^2-c(p2+t)]/2t, (d) (5 points) Given that for intermediate levels of p2, that the (partial) derivative of u1(p1; p2) with respect to p1 is (p2 + t + c)/2t, show that the best response for firm 1 for intermediate levels of p2,can be expressed as BR1(p2) = (p2 + t + c)/2, (e) (15 points) Draw a picture of the best responses of frms 1 and 2. Be careful to indicate in your picture what happens to BR1(p2) when p2 < c-t, and when p2 > 3t+c. [Hint: recall your answers to parts (a)and (b) above]. Draw the best response BR2(p1) on the same picture. (f) (10 points) Use algebra to find the Nash equilibrium.(g) (5 points) What is the equilibrium price when t = 0? Interpret youranswer. People sometimes say 'competition gets less fierce as productsbecome less similar and more differentiated'. How does this show upin our model?

ill in the blanks:Consider the department store market that has two rivals, DJs and Myer. Each firm can choose to either Advertise or Not Advertise. These choices are made simultaneously. The payoffs are given below in the following figure.  What is the total payoff for both Myer and DJs in the equilibrium? . Myer and DJs would be better off by choosing , respectively (write Advertise or Not). In that case, their total payoff would be .

Consider Apple and Samsung considering developing an entering a new market (by developing a new type of device). The timing of the game is that Apple gets to choose whether to Enter (E) or to Not Enter (NE). Then, observing its rival’s choice, Samsung gets to choose whether to E or to NE. If both firms enter (E) the payoff is -5 to each firm. If both firms do not enter (NE) they each get a profit of 2. If one enters and the other chooses to NE, the entrant gets 10 and the other firm gets a profit of 0.
