1. a. We are analyzing the market for a particular good and are given the following equations for demand and supply: P=10-Q and P=Q-4. First, determine the equilibrium price and quantity in this market.

b. Suppose the government wants to create a disincentive for the consumption of this good by placing a tax on the good in the amount of $1. How much less will be sold? How much will the buyer pay and how much will the seller get?

c. How much different would the outcomes be if the tax was instead a subsidy (you can assume a subsidy in the same amount -- $1)? When would a subsidy be used?

Two firms, LexCorp and Wayne Enterprises, have access to five production processes, each one of which has a different cost and gives off a different amount of pollution. The daily costs of the processes and the corresponding number of tons of smoke emitted are as shown in the following table: Process (smoke) A (4 tons/day) B (3 tons/day) C (2 tons/day) D (1 ton/day) E (0 tons/day) LexCorp ($/day) 80 130 200 310 500 Wayne Enterprises ($/day) 150 190 240 300 370 a. If pollution is unregulated, which production process will each firm choose, and what will be the total daily smoke emission? The firms will choose . The total daily smoke emission would be per day. b. The City Council wants to reduce total emissions down to 2 tons of smoke per day. To accomplish this, it requires each firm to reduce its emissions to 1 ton of smoke per day. What will be the total cost to society of this policy? Total cost to society will be $ . c. The City Council again wants to reduce total emissions down to 2 tons of smoke per day. This time the City Council sets a tax of $T per day on each ton of smoke emitted. How large will T have to be to reduce total emissions down to 2 tons of smoke per day? Specifically, what is the smallest whole dollar tax on each ton of smoke emitted that will guarantee that total emissions fall to 2 tons per day? Under this tax, what production process will each firm choose? If the revenue collected from taxing emissions is used to offset other taxes, then what will be the total cost to society of this policy? T would have to be $ . Under this tax, LexCorp will choose and Wayne Enterprises will choose . The total cost to society would be $ . d. Comparing the policy in part b and part c, which imposes the smallest total cost on society? Explain. The policy in part b because it concentrates pollution reduction at the firm whose marginal cost of reducing pollution is the lowest. The policy in part c because it concentrates pollution reduction at the firm whose total cost of reducing pollution is the lowest. The policy in part c because it concentrates pollution reduction at the firm whose marginal cost of reducing pollution is the lowest. The policy in part b because it concentrates pollution reduction at the firm whose total cost of reducing pollution is the lowest.

Include a discussion regarding sensitivity analysis for an inelastic product.

In many countries, armed forces rely both on volunteers and conscription for military service. For example, in Denmark, eligible men for military service are required to draw a number. Depending on the number they draw, they may get drafted if there aren't enough volunteers.

Consider a very simple game with two risk-neutral players, who are eligible for military service.[1]The Army needs only one of them.

Player 1 moves first, and decides whether or not to volunteer.

If Player 1 volunteers, then the game ends. Player 1 receives a payoff of (B -C), where B represents the benefit of volunteering and C represent the cost of joining the army, respectively. (You can think of both monetary and non-monetary benefits and costs). In this case, Player 2 gets a payoff of zero.

If Player 1 does not volunteer, then Player 2, who observes this decision, decides whether or not to volunteer.

Similarly, if Player 2 volunteers, the game ends with leaving Player 2 a payoff of (B -C), whereas Player 1 obtains a payoff of 0.  If Player 2 does not volunteer either, then the army drafts one of the players with the luck of the draw. Therefore, Player 1 and Player 2 gets drafted with an equal probability. 0.5. As the result of the draw, the player who ends up being drafted receives a payoff of –C (since the benefits of volunteering does not accrue in this case). The player who ends up not being drafted receives a payoff of 0.

a) I suggest for you to start by drawing the game tree, using Nature as a non-strategic player representing the (possible) uncertainty in the game. You do NOT need to turn this tree in, but it will be helpful to sketch it out.

b)    Let B=400 and C=600. What is the rollback equilibrium of this game? [10 points]

c)     Does this game with the payoff structure described in (b) exhibit first-mover advantage, second-mover advantage, or neither? Explain. [10 points]

d)    Now consider that Player 2 has a different value of C than Player 1.  Determine the minimum value of C, which makes the following commitment credible: “I will not volunteer regardless of what you do.” [10 points]

e)     Choose a larger value of C than you found in part (d), and solve the game for rollback equilibrium. Is the equilibrium outcome different than the one you have described in part (b)? [10 points]
