Argentina has been through several periods of hyperinflation during with the price level has increased more than 50 percent per month. The following figure shows the inflation rate as measured by the percentage change in the consumer price index from the previous month for since the beginning of 2018. The inflation rate during these years has been volatile, being greater than 50 percent per month during several periods, including staring in the spring of 2022. High rates of inflation have become so routine in Argentina that an article in the Wall Street Journal quoted on store owner as saying, “Here 40% [inflation] is normal. And when we get past 50%, it doesn’t scare us, it simply bothers us.”
As we discuss in Macroeconomics, Chapter 14, Section 14.5 (Economics, Chapter 24, Section 24.5 ), when an economy experiences hyperinflation, consumers and businesses hold the country’s currency for as brief a time as possible because the purchasing power of the currency is declining rapidly. As we noted in the chapter, in some countries experiencing high rates of inflation, consumers and businesses buy and sell goods using U.S. dollars rather than the domestic currency because the purchasing power of the dollar is more stable. This demand for dollars in countries experiencing high inflation rates is one reason why an estimated 80 percent of all $100 bills circulate outside of the United States.
The increased demand for U.S. dollars by people in Argentina is reflected in the exchange rate between the Argentine peso and the U.S. dollar. The following figure shows that at the beginning of 2018, one dollar exchanged for about 18 pesos. By November 2022, one dollar exchanged for about 159 pesos. The exchange rate shown in the figure is the official exchange rate at which people in Argentina can legally exchange pesos for dollars. In practice, it is difficult for many individuals and small firms to buy dollars at the official exchange rate. Instead, they have to use private currency traders who will make the exchange at an unofficial—or “blue”—exchange rate that varies with the demand and supply of pesos for dollars. A reporter for the Economist described his experience during a recent trip to Argentina: “Walk down Calle Lavalle or Calle Florida in the centre of Buenos Aires and every 20 metres someone will call out ‘cambio’ (exchange), offering to buy dollars at a rate that is roughly double the official one.”
People in Argentina are reluctant to deposit their money in banks, partly because the interest rates banks pay typically are lower than the inflation rate, causing the purchasing power of money deposited in banks to decline over time. People are also afraid that the government might keep them from withdrawing their money, which has happened in the past. As an alternative to depositing their money in banks, many people in Argentina buy more goods than they can immediately use and store them, thereby avoiding future price increases on these goods. The Wall Street Journalquoted a university student as saying: “I came to this market and bought as much toilet paper as I could for the month, more than 20 packs. I try to buy all [the goods] I can because I know that next month it will cost more to buy.”
Devon Zuegel, a U.S. software engineer and economics blogger who travels frequently to Argentina, has observed one unusual way that some people in Argentina save while experiencing hyperinflation:
“Bricks—actual bricks, not stacks of cash—are another common savings mechanism, especially for working-class Argentinians. The value of bricks is fairly stable, and they’re useful to a family building out their house. Argentina doesn’t have a mortgage industry, and thus buying a pallet of bricks each time you get a paycheck is an effective way to pay for your home in installments. (Bricks aren’t fully monetized, in that I don’t think people buy bricks and then sell them later, so people only use this method of saving when they actually have something they want to use the bricks for.)”

In the Apply the Concept “Trying to Use the Apple Approach to Save J.C. Penney” in Chapter 10, Section 10.4 in both Microeconomics and Economics, we discussed how Ron Johnson had been successful as head of Apple’s retail stores but failed when he was hired as CEO of J. C. Penney. Insights from behavioral economics indicate that Johnson made a mistake in eliminating Penney’s previous strategy of keeping prices high but running frequent sales. Although Penney’s “every day prices” under Johnson were lower than they had been under the previous management, many consumers failed to recognize that fact and began shopping elsewhere.
Johnson’s experience may indicate the dangers of changing a firm’s long-standing business model. Customers at brick-and-mortar retail stores fall into several categories: Some people shop in a number of stores, depending on which store has the lowest price on the particular product they’re looking for; some shop only for products such as televisions or appliances that they hesitate to buy from Amazon or other online sites; while others shop primarily in the store that typically meets their needs with respect to location, selection of products, and pricing. It’s the last category of customer that was most likely to stop shopping at Penney because of Johnson’s new pricing policy because they were accustomed to primarily buying products that were on sale.
Bed Bath & Beyond was founded in 1971 by Warren Eisenberg and Leonard Feinstein. As the name indicates, it has focused on selling household goods—sometimes called “home goods”—such as small appliances, towels, and sheets. It was perhaps best known for mailing massive numbers of 20 percent off coupons, printed on thin blue cardboard and nicknamed Big Blue, to households nationwide. Although by 2019, the firm was operating more than 1,500 stores in the United States, some investors were concerned that Bed Bath & Beyond could be run more profitably. In March 2019, the firm’s board of directors replaced the current CEO with Mark Tritton who had helped make Target stores very profitable.
In an approach similar to the one Ron Johnson had used at J.C. Penney, Tritton cut back on the number of coupons sent out, reorganized the stores to reduce the number of different products available for sale, and replaced some name brand goods with so-called private-label brands produced by Bed Bath & Beyond. Unfortunately, Tritton’s strategy was a failure and the firm, which had been profitable in 2018, suffered losses each year between 2019 and 2022. The losses totaled almost $1.5 billion. In June 2022, the firm’s board of directors replaced Tritton with Sue Grove who had been serving on the board.
Why did Tritton’s strategy fail? Partly because in March 2020, the effects of the Covid-19 pandemic forced the closure of many Bed Bath & Beyond stores. Unlike some other chains, Bed Bath & Beyond’s web site struggled to fulfill online orders. The firm also never developed a system that would have made it easy for customers to order goods online and pick them up at the curb of their retail stores. That approach helped many competitors maintain sales during the pandemic. Covid-19 also disrupted the supply chains that Tritton was depending on to produce the private-label brands he was hoping to sell in large quantities.
But the larger problems with Tritton’s strategy would likely have hurt Bed Bath & Beyond even if there had been no pandemic. Tritton thought the stores were too cluttered, particularly in comparison with Target stores, so he reduced the number of products for sale. It turned out, though, that many of Bed Bath & Beyond’s most loyal customers liked searching through the piles of goods on the shelves. One customer was quoted as saying, “I used to find so many things that I didn’t need, that I’d end up buying anyway, like July 4th-themed corn holders.” Customers who preferred to shop in less cluttered stores were likely to already be shopping elsewhere. And it turned out that many Bed Bath & Beyond customers preferred national brands and switched to shopping elsewhere when Tritton replaced those brands with private-label brands. Finally, many customers were accustomed to shopping at Bed Bath & Beyond shortly after receiving a Big Blue 20 percent off coupon. Sending out fewer coupons meant fewer trips to Bed Bath & Beyond by those customers.
In a manner similar to what happened to Johnson in his overhaul of the Penney department stores, Tritton’s changes to Bed Bath & Beyond’s business model caused many existing customer to shop elsewhere while attracting relatively few new customers. An article in the Wall Street Journal quoted an industry analyst as concluding: “Mark Tritton entered the business and ripped up its playbook. But the strategy he replaced it with was not tested and nowhere near sharp enough to compensate for the loss of traditional customers.”

As we discuss in Microeconomics and Economics, Chapter 5, Section 5.3, carbon dioxide (CO2) emissions contribute to climate change, including the increases in temperatures that have been experienced worldwide. We’ve found that students are interested in seeing U.S. CO2 emissions in a global context.
The first of the following figures shows for the years 1960 to 2020, the total amount of CO2 emissions by the United States, China, India, the 28 countries in the European Union, lower-middle-income countries (including India, Nigeria, and Vietnam), and upper-middle-income countries (including China, Brazil, and Argentina). The second of the figures shows the percentage of total world CO2 accounted for by each of the three individual countries and by the indicated groups of countries. in the United States and in the countries of the European Union both total emissions and the percentage of total world emissions have been declining over the past 15 years. Emissions have been increasing in China, India, and in middle-income countries. The figures are from the Our World in Data website (ourworldindata.org). (Note that the reductions in emissions during 2020 largely reflect the effects of the slowdown in economic activity as a result of the Covid-19 pandemic rather than long-term trends in emissions.)
Governments in many countries have attempted to slow the pace of climate change by enacting policies to reduce CO2emissions. (According to estimates by the U.S. Environmental Protection Agency, CO2 accounts for about 76 percent of all emissions worldwide of greenhouse gases that contribute to climate change. Methane and nitrous oxide, mainly from agricultural activity, make up most of the rest of greenhouse gas emissions.) In August 2022, Congress and President Biden enacted additional measures aimed at slowing climate change. Included among these measures were government subsidies to firms and households to use renewable energy such as rooftop solar panels, tax rebates for some buyers of certain electric vehicles, and funds for utilities to develop power sources such as wind and solar that don’t emit CO2. The measures have been estimated to reduce U.S. greenhouse gas emissions by somewhere between 6 percent and 15 percent. Because the United States is responsible for only about 14 percent of annual global greenhouse gas emissions, the measures would likely reduce global emissions by only about 2 percent.
The figures shown above make this result unsurprising. Because the United States is the source of only a relatively small percentage of global greenhouse emissions, reductions in U.S. emissions can result in only small reductions in global emissions. Although many policymakers and economists believe that the marginal benefit from these reductions in U.S. emissions exceed their marginal cost, the reductions can’t by themselves do more than slow the rate of climate change. A key reason that India, China, and other middle income countries have accounted for increasing quantities of greenhouse gases is that they rely much more heavily on burning coal than do the United States, the countries in the European Union, and other high-income countries. Utilities switching to generating electricity by burning coal rather than by burning natural gas has been a key source of reductions in greenhouse gas emissions in the United States.
The two figures above measure a country’s contribution to CO2 emissions by looking at the quantity of emissions generated by production within the country. But suppose instead that we look at the quantity of CO2 emitted during the production of the goods consumed within the country? In that case, we would allocate to the United States CO2 emitted during the product of a good, such as a television or a shirt, that was produced in China or another foreign country but consumed in the United States.
For the United States, as the following figure shows it makes only a small difference whether we measure CO2emissions on the basis of production of goods and services or on the basis of consumption of goods and services. U.S. emissions of CO2 are about 7 percent higher when measured on a consumption basis rather than on a production basis. By both measures, U.S. emissions of CO2 have been generally declining since about 2007. (1990 is the first year that these two measures are available.)

In Chapter 1, Section 1.1, one of our three key economic ideas is that people respond to economic incentives. Government policy can change the economic incentives that people face. Sometimes a government policy can have unintended consequences because it changes economic incentives in a way that policymakers didn’t anticipate. Some economists argue that this was the case with the Biden administration’s decision to change the federal student loan program.
In recent years, college students and their parents have rapidly increased their loan debt. The following figure shows the total value of outstanding student loans beginning in 2000. Student loan debt increased from about $52 billion in 2000 to about $1.6 trillion in 2022. Or, put another way, for every dollar of loan debt students and their parents owed in 2000, they owed more than 27 dollars of debt in 2022. In 2022, the average borrower owed about $37,000.
During the Covid–19 pandemic, the Trump and Biden administrations allowed people with student loans to suspend making payments on them. The payment moratorium began March 31, 2020 and is scheduled to end on December 31, 2022. Student loan payments are often the largest item in the budgets of recent college graduates. Some economists argue that the need to make student loan payments has made it harder for young adults to accumulate the down payments necessary to buy homes. As a result, young adults are likely to delay forming families, thereby reducing their need to move from an apartment to a house. In 1967, about 83 percent of people aged 25 to 34 lived with a spouse or partner, while in 2021 only about 54 percent did.
Some economists doubt that student loan debt explains the delay in young adults forming families and buying houses. But many policymakers have seen reducing the burden of student loan debt on young adults as an important issue. In August 2022, President Joe Biden announced a plan under which individuals earning less than $125,000 per year would have up to $10,000 in student loan debt cancelled. Borrowers with Pell grants would have up to another $10,000 cancelled. A second part of the plan involved changes to the federal government’s income-driven repayment (IDR) program. As a result of these changes, lower and middle-income student loan borrowers will be able to more easily have their loan balances canceled. With some exceptions, borrowers who have loans of $12,000 or less will have their loans canceled after making payments for 10 years, rather than the current 20 years. The annual payments for most borrowers using the IDR program will be lowered to 5 percent of their income above about $33,000 per year, rather than the previous 10 percent.
Some policymakers objected to President Biden’s plan, arguing that it was unconstitutional because it was the result of a presidential executive order rather than the result of Congressional legislation. Many economists focused on a different potential problem with the plan: the economic incentives that might result from the changes to the IDR program. The intention of these changes was to reduce the burden on people who currently have student loans, but the changes also affected the economic incentives facing students applying for loans and colleges in deciding the level of tuition to charge.
In an article on the Brookings Institution website, Adam Looney, a professor of finance at the University of Utah, argued that because of the changes to the IDR program, the typical college student could expect to pay back only about 50 percent of the amount borrowed. Before the changes, the Congressional Budget Office had estimated that the typical student would end up paying more than 100 percent of the amount borrowed because the student would have to pay interest on the loan amount. Looney argues that students and their parents will have an incentive to borrow more because they will expect to pay back only half of the amount borrowed. In particular, he notes:
“A large share of student debt is not used to pay tuition, but is given to students in cash for rent, food, and other expenses…. While students certainly need to pay rent and buy food while in school, under the administration proposal a student can borrow significant amounts for ‘living expenses,’ deposit the check in a bank account, and not pay it all back…. Some people will use loans like an ATM, which will be costly for taxpayers and is certainly not the intended use of the loans.”
Sylvain Catherine, a professor of finance at the University of Pennsylvania’s Wharton School, makes a similar argument: “How can we not anticipate the distortionary effects of such a policy? Student will be encouraged to take more debt since they will not have to repay the marginal dollar, and colleges will have an incentive to further increase tuition.” An article in the New York Times noted that taxpayers will be responsible for the value of student loans that aren’t paid back: “By offering more-generous educational subsidies, the government may be creating a perverse incentive for both schools and borrowers, who could begin to pay even less attention to the actual price tag of their education—and taxpayers could be left footing more of the bill.”
It’s too early to judge the extent to which students, their families, and colleges will react to the changed incentives in President Biden’s student debt relief plan. But because the plan changes economic incentives, it may result in consequences not intended by President Biden and his advisers. (Note that the lawsuits challenging the plan’s constitutionality have also not yet been resolved.)

Former Federal Reserve Chair Ben Bernanke (now a Distinguished Fellow in Residence at the Brookings Institution in Washington, DC), Douglas Diamond of the University of Chicago, and Philip Dybvig of Washington University in St. Louis shared the 2022 Nobel Prize in Economics (formally called the Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel). Card received half of the prize of 10 million Swedish kronor (about 8.85 million U.S. dollars) for “significantly [improving] our understanding of the role of banks in the economy, particularly during financial crises.” (The press release from the Nobel committee can be read here.)
In paper published in the American Economic Review in 1983, Bernanke provided an influential interpretation of the role the bank panics of the early 1930s played in worsening the severity of the Great Depression. As we discuss in Macroeconomics, Chapter 14, Section 14.3 (Economics, Chapter 24, Section 24.3), by taking deposits and making loans banks play an important in the money supply process. Milton Friedman and Anna Schwartz in A Monetary History of the United States, 1867-1960, Chapter 7, argued that the bank panics of the early 1930s caused a decline in real GDP and employment largely through the mechanism of reducing the money supply.
Bernanke demonstrated that the bank failures affected output and employment in another important way. As we discuss in Macroeconomics, Chapter 6, Section 6.2 and Chapter 14, Section 14.4 (Economics, Chapter 8, Section 8.2 and Chapter 24, Section 24.4) banks are financial intermediaries who engage in indirect finance. Banks accept deposits and use the funds to make loans to households and firms. Households and most firms can’t raise funds through direct finance by selling bonds or stocks to individual investors because investors don’t have enough information about households or all but the largest firms to know whether these borrowers will repay the funds. Banks get around this information problemby specializing in gathering information on households and firms that allow them to gauge how likely a borrower is to default, or stop paying, on a loan.
Because of the special role banks have in providing credit to households and firms that have difficulty borrowing elsewhere, Bernanke argued that the bank panics of the early 1930s, during which more than 5,000 banks in the United States went out of business, not only caused a reduction in the money supply but restricted the ability of households and firms to borrow. As a result, households and firms decreased their spending, which increased the severity of the Great Depression.
In a 1983 paper published in the Journal of Political Economy, Diamond and Dybvig presented what came to be known as the Diamond and Dybvig model of the economic role of banks. This model, along with later research by Diamond, provided economists with a better understanding of the potential instability of banking. Diamond and Dybvig note that banking involves transforming long-run, illiquid assets—loans—into short-run, liquid assets—deposits. Recall that liquidity is the ease with which an asset can be sold. Households and firms want the loans they receive from a bank to be illiquid in the sense that they don’t want the bank to be able to demand that the funds borrowed be repaid, except on a set schedule. Someone receiving a mortgage loan to buy a house wouldn’t want the bank to be able to insist on being paid back any time the bank chose. But households and firms also want the assets they hold to be liquid so that they can quickly convert the assets into money if they need the funds. By taking in deposits and using the funds to make loans, banks provide a service to households and firms by providing both a source of long-run credit and a source of short-term assets.
But Diamond and Dybvig note that because banks hold long-terms assets that can’t easily be sold, if a large number of people attempt simultaneously to withdraw their deposits, the banks lack the funds to meet these withdrawals. The result is a run on a bank as depositors become aware that unless they quickly withdraw their deposits, they may not receive their funds for a considerable time. If the bank is insolvent—the value of its loans and other assets is less than the value of its deposits and other liabilities—the bank may fail and some households and firms will never receive the full value of their deposits. In the Diamond and Dybvig model, if depositors expect that other depositors will not withdraw their funds, the system can be stable because banks won’t experience runs. But because banks know more about the value of their assets and liabilities than depositors do, depositors may have trouble distinguishing solvent banks from insolvent banks. As a result of this information problem, households and firms may decide to withdraw their deposits even from solvent banks. Households and firms may withdraw their deposits from a bank even if they know with certainty that the bank is solvent if they expect that other households and firms—who may lack this knowledge—will withdraw their deposits. The result will be a bank panic, in which many banks simultaneously experience a bank run.
With many banks closing or refusing to make new loans in order to conserve funds, households and firms that depend on bank loans will be forced to reduce their spending. As a result, production and employment will decline. Falling production and employment may cause more borrowers to stop paying on their loans, which may cause more banks to be insolvent, leading to further runs, and so on. We illustrate this process in Figure 14.3.
Diamond and Dybvig note that a system of deposit insurance—adopted in the United States when Congress established the Federal Deposit Insurance Corporation (FDIC) in 1934—or a central bank acting as a lender of last resort to banks experiencing runs are necessary to stabilize the banking system. When Congress established the Federal Reserve System in 1914, it gave the Fed the ability to act as a lender of last resort by making discount loans to banks that were solvent but experiencing temporary liquidity problems as a result of deposit withdrawals.
During the Global Financial Crisis that began in 2007 and accelerated following the failure of the Lehman Brothers investment bank in September 2008, it became clear that the financial firms in the shadow banking system could also be subject to runs because, like commercial banks, shadow banks borrow short term to financial long term investments. Included in the shadow banking system are money market mutual funds, investment banks, and insurance companies. By 2008 the size of the shadow banking system had grown substantially relative to the commercial banking system. The shadow banking system turned out to be more fragile than the commercial banking system because those lending to shadow banks by, for instance, buying money market mutual fund shares, do not receive government insurance like bank depositors receive from the FDIC and because prior to 2008 the Fed did not act as a lender of last resort to shadow banks.
Bernanke believes that his study of financial problems the U.S. experienced during the Great Depression helped him as Fed chair to deal with the Global Financial Crisis. In particular, Bernanke concluded from his research that in the early 1930s the Fed had committed a major error in failing to act more vigorously as a lender of last resort to commercial banks. The result was severe problems in the U.S. financial system that substantially worsened the length and severity of the Great Depression. During the financial crisis, under Bernanke’s leadership, the Fed established several lending facilities that allowed the Fed to extend its role as a lender of last resort to parts of the shadow banking system. (In 2020, the Fed under the leadership of Chair Jerome Powell revived and extended these lending facilities.) Bernanke is rare among economists awarded the Nobel Prize in having had the opportunity to implement lessons from his academic research in economic policymaking at the highest level. (Bernanke discusses the relationship between his research and his policymaking in his memoir. A more complete discussion of the financial crises of the 1930s, 2007-2009, and 2020 appears in Chapter 14 of our textbook Money, Banking, and the Financial System, Fourth Edition.)
We should note that Bernanke’s actions at the Fed have been subject to criticism by some economists and policymakers. As a member of the Fed’s Board of Governors beginning in 2002 and then as Fed chair beginning in 2006, Bernanke, like other members of the Fed and most economists, was slow to recognize the problems in the shadow banking system and, particularly, the problems caused by the rapid increase in housing prices and increasing number of mortgages being granted to borrowers who had either poor credit histories or who made small down payments. Some economists and policymakers also argue that Bernanke’s actions during the financial crisis took the Fed beyond the narrow role of stabilizing the commercial banking system spelled out by Congress in the Federal Reserve Act and may have undermined Fed independence. They also argue that by broadening the Fed’s role as a lender of last resort to include shadow banks, Bernanke may have increased the extent of moral hazard in the financial system.
Finally, Laurence Ball of Johns Hopkins University argues that the worst of the financial crisis could have been averted if Bernanke had acted to save the Lehman Brothers investment bank from failing by making loans to Lehman. Bernanke has argued that the Fed couldn’t legally make loans to Lehman because the firm was insolvent but Ball argues that, in fact, the firm was solvent. Decades later, economists continue to debate whether the Fed’s actions in allowing the Bank of United States to fail in 1930 were appropriate and the debate over the Fed’s actions with respect to Lehman may well last as long. (A working paper version of Ball’s argument can be found here. He later extended his argument in a book. Bernanke’s account of his actions during the failure of Lehman Brothers can be found in his memoir cited earlier.)

In a blog post at the end of August, we noted that real GDP declined during the first two quarters of 2022. On September 29, the Bureau of Economic Analysis (BEA) slightly revised the real GDP data, but after the revisions the BEA’s estimates still showed real GDP declining during those quarters.
A popular definition of a recession is two consecutive quarters of declining real GDP. But, as we noted in the earlier blog post, most economists do not follow this definition. Instead, for most purposes, economists rely on the National Bureau of Economic Research’s business cycle dating, which is based on a number of macroeconomic data series. The NBER defines a recession as “a significant decline in activity spread across the economy, lasting more than a few months, visible in industrial production, employment, real income, and wholesale-retail trade.” The NBER discusses its approach to business cycle dating here.
The Federal Reserve Bank of St. Louis’s invaluable FRED economic data site has collected the data series that the NBER’s Business Cycle Dating Committee relies on when deciding when a recession began. The FRED page collecting these data can be found here.
Note that although the Business Cycle Dating Committee analyzes a variety of data series, “In recent decades, the two measures we have put the most weight on are real personal income less transfers and nonfarm payroll employment.” The following figures show movements in those two data series. These data series don’t give a strong indication that the economy was in recession during the first half of 2022. Real personal income minus transfer payments did decline by 0.4 percent between January and June 2022 (before increasing during July and August), but nonfarm payroll employment increased by 1.4 percent during the same period (and increased further in July and August).
As we noted in our earlier blog post, the message from most data series other than real GDP seems to be that the U.S. economy was not in a recession during the first half of 2022.

Between June 2021 and September 2022, the exchange rate between the U.S. dollar and an average of the currencies of the major trading partners of the United States increased by 14 percent. (This movement is shown in the figure above.) An article in the New York Times had the headline “The Dollar Is Strong. That Is Good for the U.S. but Bad for the World.”
Briefly explain what the headline means by a “strong” dollar.
Do you agree with the assertion in the headline that a stronger dollar is good for the United States but bad for the economies that the United States trades with? Briefly explain.
During this period the Federal Reserve was taking actions that raised U.S. interest rates. The article noted that “Those interest rate increases are pumping up the value of the dollar ….” Why would increases in U.S. interest rates relative to interest rates in other countries increase the value of the dollar?
Solving the Problem
Step 1: Review the chapter material. This problem is about the effect of fluctuations in the exchange rate and the relationship between interest rates and exchange rates, so you may want to review Macroeconomics, Chapter 18, Section 8.2, “The Foreign Exchange Market and Exchange Rates,” or the corresponding sections in Economics, Chapter 28 or Essentials of Economics, Chapter 19.
Step 2:Answer part a. by explaining what a “strong” dollar means. A strong dollar is one that exchanges for more units of foreign currencies, such as British pounds or euros. (A “weak” dollar means the opposite: A dollar that exchanges for fewer units of foreign currencies.)
Step 3: Answer part b. by explaining whether you agree with the assertion that a stronger dollar is good for the United States but bad for the economies of other countries. A stronger U.S. dollar produces winners and losers both in the United States and in other countries. U.S. consumers win because a stronger dollar means that fewer dollars are needed to buy the same quantity of a foreign currency, which reduces the dollar price of imports from that country. For example, a stronger dollar reduces the number of dollars U.S. consumers pay to buy a bottle of French wine that has a 40 euro price. A strong dollar is bad news for foreign consumers because they must pay more units of their currency to buy goods imported from the United States. For example, Japanese consumers will have to pay more yen to buy an imported Hershey’s candy bar with a $1.25 price.
The situation is reversed for U.S. and foreign firms exporting goods. Because foreign consumers have to pay higher prices in their own currencies for goods imported from the United States, they are likely to buy less of them, buying more domestically produced goods or goods imported from other countries. U.S. firms will either to have accept lower sales, or cut the prices they charge for their exports. In either case, U.S. exporters’ revenue will decline. Foreign firms that export to the United States will be in the opposite situation: The dollar prices of their exports will decline, increasing their sales.
We can conclude that the article’s headline is somewhat misleading because not all groups in the United States are helped by a strong dollar and not all groups in other countries are hurt by a strong dollar.
Step 4: Answer part c. by explaining why higher interest rates in the United States relative to interest rates in other countries will increase the exchange value of the dollar. If interest rates in the United States rise relative to interest rates in other countries—as was true during the period from the spring of 2021 to the fall of 2022—U.S. financial assets, such as U.S. Treasury bills, will be more desirable, causing investors to increase their demand for the dollars they need to buy U.S. financial assets. The resulting shift to the right in the demand curve for dollars will cause the equilibrium exchange rate between the dollar and other currencies to increase.
