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]

Review Handout | Absolute Advantage and Comparative Advantage | Cases 1-3 (3 pages)

*Holding other things constant and considering the usual assumptions for the 2C-2G-1F model and production per unit of labor for both Case 1 and Case 2 below, determine which country has the absolute advantage and comparative advantage in which good.

Example Case 1

To determine who has a comparative advantage in which good, we will need to calculate opportunity costs of good X and good Y in each country first.

In the case of Country A above, the opp. cost of X (in terms of Y) is the number of units of Good Y Country A should give up in order to produce one more unit of Good X.   To find out this, we can simply divide the number of Good X and Good Y per unit of labor in each cell by 60, respectively, so that we can see how many units of Good Y Country A should give up to produce one more unit of Good X in Country A.   As shown above, it will be 1.33.  

By the same token, in the case of Country A, the opp. cost of Y (in terms of X) is the number of units of Good X Country A should give up in order to produce one more unit of Good Y.   To find out this, we can simply divide the number of Good Y and Good X per unit of labor in each cell by 80, respectively, so that we can see how many units of Good X Country A should give up to produce one more unit of Good Y in Country A.   As shown above, it will be 0.75.  

1. Which country has an absolute advantage in producing X and Y, respectively?

Hint) Per unit of labor, which country is producing Good X (Good Y) more in absolute terms?

2. Country A has a comparative advantage in producing:

3. Country B has a comparative advantage in producing:

Case 2

1. Which country has an absolute advantage in producing wine and wool, respectively?

2. Portugal has a comparative advantage in producing:

3. The U.K. has a comparative advantage in producing:

Case 3. Now assume that country “American” can produce either 20 songs or 40 boxes of roses per week. Assume that country “Eagle” can produce 10 songs or 50 boxes of roses per week. Consider the usual assumptions holding other things constant.

1. Which has a comparative advantage in the production of songs?

2. Which has a comparative advantage in the production of roses?

3. If each produces songs for one week and then roses for one week, show the total    production of both goods.

4. Now, assume each country specializes for two weeks. Indicate the total production of both goods. Show that trade between the two countries after this two-week period can allow both countries to consume both more roses and songs.

Has the Federal Reserve done more harm than good? This is not a simple yes or no question. I need you to fully explain your answer with at least one source cited.

Response must be at least 250 words

2. Which of the following costs are always increasing as output increases? (a) Variable Cost only (b) Fixed Cost only (c) Marginal Cost only (d) Total Cost only (e) Total Cost and Variable Cost

3.A firm has a Cobb-Douglas production function ? = 50√ ??. This function exhibits a constant return to scale. The total cost function for this production process is ? ? = ? · √ ?·? 50 , where ? is output level, ? and ? are prices of labor and capital. The marginal cost of production for this function is: (a) Constant. (b) Increasing. (c) Decreasing. (d) None of the above.

4. If some production function ?(?, ?) exhibits an increasing return to scale, then the marginal cost of production decreases as output level increases. (a) True. (b) False. (c) Not enough information given. (d) None of the above.

5. It will never cost more to produce a certain amount of output in the long run than in the short run. (a) True. (b) False. (c) Not enough information given. (d) None of the above.

why might it be better for governments to borrow money from foreign countries or entities than borrowing domestically

Why is it important to study the internal resources, capabilities, and activities of firms? What insights can be gained?

The inverse market demand for clothing is P=48–2Q and the cost function is C=Q².

1 Calculate the optimal profit of a monopolist.

Assume now that the monopolist can choose whether to continue operating in the market as a monopolist or set up two branches that operate in the market as Cournot duopolists (duopolist branching). Each branch will face the same quadratic cost function as the original monopolist.

2 Calculate the optimal profit under the duopoly branching. Will the firm prefer to produce with one or two branches? Explain whether this is counter intuitive.

3 Every unit of output Q generates a social cost of 10. The government chooses to pass on that cost to the firm as a lump sum to pay. In this situation, does the firm prefer to produce with one or with two branches operating as Cournot duopolists?

_____ 1. Which of the following statements about a monopoly is false?

1. With price discrimination deadweight loss is smaller but consumer surplus is also smaller
2. For a monopolized market to stay monopolized there have to be barriers to entry
3. With a monopoly, price will equal marginal cost
4. The more inelastic the demand, the higher the mark up of price over marginal cost

_____ 2. Which of the following statements about externalities is true?

1. A positive consumption externality will result in over consumption. The government should subsidize consumers to fix it.

3. With a positive externality in consumption social benefit is above private benefit
4. Negative externalities create inefficiency but positive externalities improve it

2. True or False

1. In the long run, demand is more price elastic than in the short run

TRUE                                                              FALSE

2. An increase in the number of firms will result in higher price and lower consumer surplus
