    A U.S. export-import shipping company operates a general cargo carrier service between New York and several western European ports.
    It hauls two major categories of freight: manufactured items (Q1) and semimanufactured raw materials (Q2).
    The demand functions for these two classes of goods are:
    P1 = 300 − Q1
    P2 = 80 − Q2
    where Qi = tons of freight moved.
    The total cost function for the United States is TC = 20 + 4(Q1 + Q2)
    What is the firm’s total profit function?
    296Q1−Q12+76Q2−Q22−20
    300Q1−Q12+80Q2−Q22−20
    299Q1−Q12+60Q2−Q22−20
    296Q1−Q12+76Q2−Q22
    The profit-maximizing levels of price and output for manufactured items are per ton and tons, respectively.
    The profit-maximizing levels of price and output for semimanufactured raw materials are per ton and tons, respectively.
    At these levels of output the marginal revenue in the manufactured items market is and the marginal revenue in the semimanufactured raw materials market is .
    At these prices, the price elasticity of demand in the manufactured items market is and the price elasticity of demand in the semimanufactured raw materials market is . (Hint: ED=PMR−PED=PMR−P)
    What are the total profits if the company is effectively able to charge different prices in the two markets? .
    If the company is required by law to charge the same per-ton rate to all users, the new profit-maximizing level of price and output are per ton and tons respectively. The total profits in this situation is .

    ➤ How does playing a dominant strategy lead supermarkets to worse outcomes?
    A dominant strategy is the best response regardless of the rival’s move. If price cutting is dominant for each firm, both choose it to avoid losing customers. The resulting Nash equilibrium leaves them worse off than if they had cooperated, producing a Pareto‑inferior outcome despite rational choices.

    Question 3.
    A seller S owns a single indivisible good. There is one potential buyer B. The seller’s utility if he sells the good and receives a transfer payment tS is equal to tS. If he does not sell the good and receives a transfer tS then his utility is θS + tS, where θS is a random variable with cumulative distribution function FS and density fS. We assume that FS has support θ(S), bar (θ)S and that fS(θS) > 0 for all θS in [θ(S), bar (θ)S].
    The buyer’s utility if he purchases the good and pays a transfer tB equals θB − tB, where θB is a random variable with cumulative distribution function FB and density fB. We assume that FB has support θ(B), bar (θ)B and that fB(θB) > 0 for all θB in [θ(B), bar (θ)B]. The buyer’s utility if he does not obtain the good and pays transfer tB is −tB.
    The random variables θS and θB are independent. In addition, bar (θ)S > θB and θ(S) b = 0.
    The designer seeks a mechanism which is (1) ex-ante budget-balanced, (2) interim individually rational and (3) Bayesian Incentive Compatible. Using the above result, write down the constraints and the implications of these requirements.
    Hint:
    While solving the exercise, watch out for the payoff function of the seller. In order to use the results obtained for the linear model during the lecture, it is useful to rewrite the seller’s payoff as −x θS − tilde(t)S, with tilde(t)S = −tS. This does not change the mechanism designer’s problem because we included an additively separable constant to the seller’s payoff function. But, doing so, one sees that the

    (Continuing with the situation described in the preceding question) Consider the following model of immigration to the United States. Potential migrants originate in country 0 , the source country. For each individual, Ifetime income if they remain in the source country (denoted by YO) is given by the equationYO=MO RO(5)where 5 measures the skill level of each person, with positive values of 5 indicating aboveaverage skills, negative values of 5 indicating below-average skills, and 5 equal to zero for the average person. Lifetime income if a person immigrates to the United States (denoted by Y1) also varles with skitts, as described by the equationY1=M1 R1($)The parameters MO, M1, R0, and R1 characterize the lifetime income distributions in the two countries. Let C represent the total costs incurred when immigrating to the United States, Inctuding any psychic costs associated with leaving one’s home country. Assume the following:M0>M1-C>0 and R0>R1>0Assume that individuals seek to maximize their lifetime income.Under these circumstances, what happens when RO increases?

    2. Discouraged workers
    Which of the following statements correctly describe discouraged workers? (If none of the choices apply, leave all of the checkboxes blank.) Check all that apply.
    They have given up on looking for a job.
    They are counted as part of the labor force by the Bureau of Labor Statistics.
    They are employed workers who want to earn higher wages.
    They have not looked for a job in 4 weeks (or longer), but they would like a job and are available for work.
    The following table contains U.S. employment information from August 2019.

    Unemployed (Persons)
    6,044,000
    Discouraged (Persons)
    467,000
    The Bureau of Labor Statistics has several measures of joblessness in addition to the official unemployment rate. One alternative is the U-4 measure of labor underutilization, which is calculated as follows:
    U-4 = 100 × (Unemployed + Discouraged) / (Labor Force + Discouraged)
    Fill in the following table by calculating the official unemployment rate and the U-4 measure of labor underutilization.
    Measure
    Value (Percent)
    Official Unemployment Rate (Percent)
    U-4 Measure of Labor Underutilization (Percent)
    The official unemployment rate and the U-4 measure of labor underutilization are two different measures of joblessness in the economy. If the Bureau of Labor Statistics were to include discouraged workers in the official unemployment rate, the reported unemployment rate would be higher.

    The area of intellectual property (IP) has become a critical component of international business in our globalized economy.
    As trade and irvestment have expanded between countries, it is imperative that companies that have developed advanced technology can comfortably enter a new country without the threat of their technology or ideas being stolen and sold under a different source.
    If the global community is not able to effectively protect this then certain countries with a higher prevalence of IP protection issues will not attract an optimal level of international irrvestment and could slow the ability to grow their economies, as well as limit international companies’ opportunities for new market growth.
    The World Trade Organization (WTO) and WIPO (World Intellectual Property Organization) have provided a certain level of partnership among the WTO member countries in this area.
    However, a main weakness in terms of effectiveness is that enforcement is the main tenet of IP law, therefore if these measures are not effectively enforced, then IP issues will persist in many parts of the world.
    individual countries should apply pressure on each country to which they trade in order to protect the IP of their companies.
    The WTO has 164 countries that are members, and WIPO have 189 invited members, thus the number of countries is so large that neither organization could be expected to promote specific IP items uniformly.
    bribery is a serious issue in many countries around the world and can lead to IP laws being broken.

    Consider an aggregate demand and aggregate supply model where, in the short run, aggregate capital is fixed at the level $\bar K$. The aggregate demand curve, aggregate output (Y) demanded as a function of aggregate price level (P), is given by a standard downward-sloping curve. The aggregate supply curve, aggregate output (Y) supplied as a function of aggregate price level (P), is not standard, and the question leads you to derive the aggregate supply curve. The aggregate production function is linear in capital and labour (L): $ Y = AL+ \bar K$, A > 0. The labour union is very powerful and dictates the minimum aggregate nominal wage rate as W. Each worker is endowed with one unit of labour which they supply inelastically if the producers offer the nominal wage $ W > \bar W$. A worker does not supply any labour if $W < \bar W$. At W = W, a worker is indifferent between supplying and not supplying her labour endowment. The number of workers available in the economy is fixed at $\bar L$. (a) Derive, with a clear explanation, the aggregate labour supply $(L^S)$ in this economy as a function of the aggregate nominal wage rate, W. (b) Note that the marginal product of labour is constant, A > 0.
    (i) Derive, with a clear explanation, the aggregate labour demand $(L^D)$ in this economy as a function of the real wage rate, W/p.
    (ii) Using your answer to part (i) above, derive the aggregate labour demand $(L^D)$ in this economy as a function of the aggregate nominal wage rate, W.

    2. The theory of liquidity preference and the downward-sloping aggregate demand curve
    Suppose the money market for some hypothetical economy is given by the following graph, which plots the money demand and money supply curves. Assume the central bank in this economy (the Fed) fixes the quantity of money supplied. Suppose the price level increases from 90 to 105. Shift the appropriate curve on the graph to show the impact of an increase in the overall price level on the market for money.
