➤ How do I decide who should specialize in X or Y for this problem?
Compute each person’s opportunity cost for X and for Y. The person who gives up fewer units of Y to produce one X should specialize in X. Conversely, the person who sacrifices fewer units of X to make one Y should specialize in Y. Then assign full production to those goods before trade.

Consider the weekly market for gyros in a popular neighborhood close to campus. Suppose this market is operating in long-run competitive equilibrium with many gyro vendors in the neighborhood, each offering basically the same gyros. Due to the structure of the market, the vendors act as price takers and each individual vendor has no market power.
The following graph displays the supply (S = MC) and demand (D) curves in the weekly market for gyros. Place the black point (plus symbol) on the graph to indicate the market price and quantity that will result from competition.
Now assume that one of the gyro vendors successfully petitions the neighborhood development board to obtain exclusive rights to sell gyros in the neighborhood. This firm buys up all the rest of the gyro food trucks in the area and begins to operate as a monopoly. Assume that this change does not affect demand and that the marginal cost curve of the new monopoly corresponds exactly to the supply curve from the previous graph. The following graph reflects this new set of assumptions, and shows the demand (D), marginal revenue (MR), and marginal cost (MC) curves for the monopoly vendor. Place the black point (plus symbol) on the following graph to indicate the profit-maximizing price and quantity of a monopolist.
Monopoly
Consider the welfare effects that result from the industry operating as a competitive market versus a monopoly. On the monopoly graph, use the black points (plus symbol) to shade the area that represents the loss of welfare, or deadweight loss, caused by a monopoly. That is, show the area that was formerly part of total surplus and now does not accrue to anybody. Deadweight loss occurs when a market is controlled by a monopoly because the resulting equilibrium is different from the (efficient) competitive outcome.
In the following table, enter the price and quantity that would arise in a competitive market; then enter the profit-maximizing price and quantity that would be chosen if a monopolist controlled this market.

Given the summary table of the two different market structures, you can infer that, in general, the price is higher under a ____ and the quantity is higher under a ____.

Expectations and the Phillips curveThe following graph shows an economy in long-run equilibrium at point A (grey star symbol). The vertical line is the long-run Phillips curve (LRPC). The downward-sloping curve labeled SRPC1 is the short-run Phillips curve passing through point A .Which of the following is true along SRPC1 ?
The natural rate of unemployment is 3%.
The expected inflation rate is 5%.
The actual unemployment rate is 6%.
Suppose that the Fed suddenly and unexpectedly decreases the money supply in an effort to reduce inflation. As a result of this unanticipated action, actual inflation falls to 3%.
On the previous graph, use the black point (plus symbol) to illustrate the short-run effects of this policy.
Now, suppose that-after a period of 3% inflation-households and firms begin to expect that the inflation rate will continue to be 3%. On the previous graph, use the purple line (diamond symbol) to draw SRPC2, the short-run Phillips curve that is consistent with these expectations, assuming that it is parallel to SRPC1. Finally, use the orange point (square symbol) to indicate the new, long-run equilibrium for this economy.
The inflation rate at the new long-run equilibrium (point C ) is _ the inflation rate at point A , and the unemployment rate at point C is _ the unemployment rate at point A .
Was the Fed able to achieve its goal of lowering inflation?
No, because the Fed cannot affect the inflation rate through monetary policy.
Yes, the Fed’s policy successfully reduced inflation in both the short run and the long run.
Yes, but only in the short run; in the long run, inflation returned to its natural rate.
Now, suppose that the public fully anticipates the Fed’s decision to decrease the money supply. Assume the public also believes that the Fed is firmly committed to carrying out this policy. According to rational expectations theory, when the economy is in long-run equilibrium, a fully anticipated decrease in the money supply will cause the economy to moveon the previous Phillips curve graph. In this case, rational expectations theory predicts that the fully anticipated decrease in the money supply will have the immediate effect of in the unemployment rate.

The Federal Open Market Committee (FOMC) is focused on achieving its dual mandate of maximum employment and stable prices. Currently, the U.S. economy remains solid, with a low unemployment rate of 4.2 percent indicating a labor market near maximum employment. Inflation has decreased significantly from its peak in mid-2022 but is still slightly above the 2 percent target, with total PCE prices rising 2.3 percent and core PCE prices rising 2.6 percent over the past year. Despite heightened uncertainty, particularly due to trade policy concerns, the FOMC has decided to keep the policy interest rate unchanged, believing that the current stance of monetary policy positions them well to respond to future economic developments. While consumer spending growth has moderated, private domestic final purchases grew at a solid rate, and investment in equipment and intangibles has rebounded. Overall, the labor market is not contributing significantly to inflationary pressures, and most long-term inflation expectations remain aligned with the FOMC’s goals.
The Federal Open Market Committee (FOMC) is maintaining the federal funds rate target range at 4.25 to 4.5 percent while continuing to reduce the balance sheet, as part of its commitment to its dual mandate of promoting maximum employment and stable prices. The new administration’s policy changes in trade, immigration, fiscal policy, and regulation introduce significant uncertainty, particularly with larger-than-expected tariff increases. These tariffs could lead to higher inflation, slower economic growth, and increased unemployment, with the potential for inflationary effects to be either short-lived or more persistent. The FOMC emphasizes the importance of keeping long-term inflation expectations well anchored to prevent a temporary price level increase from becoming an ongoing inflation issue. The Committee is prepared to adjust its policy stance based on evolving economic conditions and is currently conducting a five-year review of its monetary policy framework, focusing on inflation dynamics and strategy, with input from diverse stakeholders. The review is expected to conclude by late summer.

The sporting goods store almost certainly has more exposure to a recession than the pediatrician’s office. This is primarily due to the nature of the products and services they offer. Sporting goods, like equipment, apparel, and recreational items, fall under discretionary spending. When a recession hits, consumer confidence drops, and disposable income shrinks. People prioritize essential needs (housing, food, utilities, healthcare) and cut back significantly on non-essential purchases. Parents, facing financial uncertainty, would likely defer or forego buying new sports equipment for their children.
Conversely, medical care, especially pediatric care, is largely non-discretionary. While some elective procedures might be postponed, routine check-ups, vaccinations, and urgent care for sick children are considered essential services. Parents will almost certainly prioritize their child’s health and well-being, making a pediatrician’s appointment one of the very last things they would cut back on. This provides the pediatrician’s practice with significantly more stability and consistent demand even during an economic downturn.
Assuming both businesses have their fixed costs covered, the sporting goods store’s income would likely increase at a faster rate. This boils down to their differing cost structures. The sporting goods store operates with mostly variable costs. This means that the primary cost associated with each additional sale is the cost of the goods sold. Once the fixed costs (like rent for the store) are covered, a large portion of the revenue from each new sale directly contributes to profit. As sales dramatically increase, the variable costs increase proportionally, but the profit per unit sold remains robust, leading to a faster escalation in overall income.
The pediatrician, on the other hand, has mostly fixed costs, such as rent for the office, salaries for receptionists and nurses, and depreciation on medical equipment. While each additional patient brings in revenue, the capacity of the practice is inherently limited by these fixed resources. To dramatically increase patient numbers beyond a certain point, the pediatrician would likely need to incur more fixed costs ( hiring another doctor, expanding office space, buying more equipment).

Question 1 (14 points)
In our discussion of labor market pooling, we stressed the advantages of having two firms in the same location: If one firm is expanding while the other is contracting, it’s to the advantage of both workers and firms that they be able to draw on a single labor pool. But it might happen that both firms want to expand or contract at the same time. Does this constitute an argument against geographical concentration? To answer this question, imagine that there are two companies that both use the same kind of specialized labor, say, two film studios that make use of experts in computer animation. Suppose that there are 450 workers with this special skill. Now compare two different scenarios: In scenario 1, both firms and all 450 workers are in the same city, and each firm is able to hire 225 workers. In scenario 2 , the two firms, each with 225 workers, are in two different cities. Now suppose that both firms experience an increase in demand for their products and as a result want to hire up to 255 workers.
a) (2 points) In the first scenario (when both firms and all workers are located in the same city), will the firms face a surplus or shortage of workers? How many?
b) (2 points) In the second scenario (when each firm is in a different city with 225 workers), will the firms face a surplus or shortage of workers? How many?
c) (2 points) Is there any advantage or disadvantage in scenario 1 relative to scenario 2 when both firms are expanding?
Now, suppose firm 1 experiences an increase in demand for its product as a result it wants to hire up to 255 workers but firm 2 experiences a decrease in demand as a result it wants to lay off 30 workers.
d) (3 points) In the first scenario (when both firms and all workers are located in the same city), will the firms face a surplus or shortage of workers? How many?
e) ( 3 points) In the second scenario (when each firm is in a different city with 225 workers), will the firms face a surplus or shortage of workers? How many?
f) (2 points) Is there any advantage or disadvantage in scenario 1 relative to scenario 2 when one firm is expanding and the other firm is contracting?
