Solved Problem: The Macroeconomic Effects of a Stronger Euro

In December 2020, an article in the Wall Street Journal discussed the effects of changes in the value of the euro in exchange for the U.S. dollar. The article noted that: “A stronger euro makes exports from the region less competitive overseas” and that a stronger euro would also “damp inflation” in countries using the euro as their currency.

a. What does the article mean by a “stronger euro”? Why would a stronger euro make European exports less competitive?

b. What does the article mean by “damp inflation”? Why would a stronger euro damp inflation in countries using the euro?

Solving the Problem

Step 1:   Review the chapter material. This problem is about the effect of changes in the exchange rate on a country’s (or region’s) imports and exports, so you may want to review Chapter 28, Section 28.2 “How Movements in Exchange Rates Affect Imports and Exports.”

Step 2:   Answer part a. by explaining what a “stronger euro” means and why a stronger euro would make European exports less competitive. A stronger euro is one that exchanges for more dollars or, which amounts to the same thing, requires fewer euros to exchange for a dollar. (You may want to review the Apply the Concept “Is a Strong Currency Good for a Country?”) A stronger euro results in U.S. consumers having to pay more dollars to buy goods and services imported from Europe. In other words, the prices of European exports to the United States will rise making the exports less competitive with U.S.-produced goods or with other countries exports to the United States. If the euro is also becoming stronger against currencies such as the British pound, Japanese yen, and Chinese yuan, then European exports will also be less competitive in those countries.

Step 3:   Answer part b. by explaining what “damp inflation” means and why a stronger euro would damp inflation in countries using the euro. To “damp inflation” is to reduce inflation. So the article is stating that a stronger euro will result in lower inflation in Europe. To understand why, remember that while a stronger euro will raise the dollar price of European exports to the United States, it will reduce the euro price of European imports from the United States (and from other countries if the euro is also becoming stronger against currencies such as the British pound, Japanese yen, and Chinese yuan). Inflation in a country is measured using the prices of goods and services that consumers purchase, whether those goods and services are produced domestically or are imported.

Christopher Waller Confirmed by Senate as Federal Reserve Governor

Christopher Waller

On Thursday, December 3, Christopher Waller, executive vice president and research director at the Federal Reserve Bank of St. Louis, was confirmed by the Senate as a member of the Federal Reserve’s Board of Governors.  The Board of Governors has seven members and, under the Federal Reserve Act, is responsible for the monetary policy of the United States and for overseeing the operation of the Federal Reserve System.

Board members are appointed by the president and confirmed by the Senate to 14-year nonrenewable terms. The terms are staggered so that one expires every other January 31. Members frequently leave the Board before their terms expire to return to their previous occupations or to accept other positions in the government. The following table shows the current Board members, when their terms will expire, and which president appointed them.  Note that one seat on the Board is vacant. President Trump nominated Judy Shelton to fill this seat but it appears unlikely that she will be confirmed by the Senate before the change in administration takes place on January 20.

Janet Yellen Nominated to Be Treasury Secretary

Janet Yellen

President-elect Joe Biden has nominated Janet Yellen to be treasury secretary. If confirmed by the Senate, Yellen would be the first woman to hold that post. She would also be the first person to have been both Federal Reserve Chair and treasury secretary. Yellen also served as President of the Federal Reserve Bank of San Francisco and as Chair of the Council of Economic Advisers during the Clinton administration. Prior to entering government service, Yellen was on the economics faculties of Harvard University and the University of California, Berkeley. At the time of her nomination she was a Distinguished Fellow in Residence at the Brookings Institution.

A news story on her nomination can be read HERE. Her biography on the Brookings Institution web site is HERE (includes a video conversation from a few years ago with former Fed Chair Ben Bernanke). A speech she gave in 2018 reflecting on the 2007-2009 financial crisis can be read HERE.

Solved Problem: Pricing Video Games

Supports:  Econ (Chapter 12 – Oligopoly: Firms in Less Competitive Markets (Section 14.2); Essentials: Chapter 11 – Monopolistic Competition and Oligopoly (Section 11.6)

Solved Problem: Pricing Video Games

   In November 2020, an article on discussed the pricing of video games for consoles like PlayStation and Xbox. The article noted that firms selling video games had kept prices constant at $60 per game since 2005. But this stable price was about to change: “This week, video game publishers will press ahead with an industry-wide effort to raise the standard price to $70.” An article in the Wall Street Journal indicated that the number of people playing video games has been increasing and had reached 244 million in the United States and 3.1 billion worldwide in 2020. Answer the following questions assuming that the video game industry is an oligopoly.

a. Is it likely that the demand for video games and the cost of producing them have remained constant for 15 years? If not, what can explain the fact that the prices of video games remained constant from 2005 to 2020?

b. Given your answer to part a., what can explain the fact that the prices of video games increased by $10 in 2020? Does the fact that this increase was an “industry-wide effort” matter? Briefly explain.

Sources: Olga Kharif and Takashi Mochizuki, “Video Game Prices Are Going Up for the First Time in 15 Years,”, November 9, 2020; and Sarah E. Needleman, “From ‘Fall Guys’ to ‘Among Us,’ How America Turned to Videogames Under Lockdown,” Wall Street Journal, October 31, 2020.

Solving the Problem

Step 1:   Review the chapter material. This problem is about pricing in an oligopolistic industry, so you may want to review Chapter 14, Section 14.2 “Game Theory and Oligopoly.”

Step 2:   Answer part a. by discussing whether it’s likely that the demand for video games and the cost of producing them have remained constant for 15 years and by providing an alternative explanation for the prices of video games remaining constant over this period. Over such a long period, it’s unlikely that the demand for video games and the cost of producing them have remained constant. For one thing, the Wall Street Journal article indicates that the number of people playing video games has been increasing, reaching 244 million in the United States in 2020 (out of a U.S. population of about 330 million). The cost of producing most consumer electronics has declined over the years. Although we are not given specific information that the cost of producing video games has followed this pattern, it seems probable that it did. So, it’s unlikely that the reason that the prices of video games have remained constant is that the demand for video games and the cost of producing them have remained unchanged.

The problem tells us to assume that the video game industry is an oligopoly. We know that price stability in an oligopolistic industry can sometimes be the result of the firms in the industry finding themselves in a prisoner’s dilemma. In this situation, the most profitable strategy for a firm is to match the low price charged by competitors even though the firm and its competitors could, both as a group and individually, earn larger profits by all charging a higher price. It seems more likely that the firms in the video game industry were stuck for years in a prisoner’s dilemma than that they have faced unchanged demand and production costs over such a long period.

Step 3:   Answer part b. by explaining why the prices of video games increased by $10 in 2020, taking into account that the increase was an “industry-wide effort.” As we note in the textbook, the prisoner’s dilemma is an example of a noncooperative equilibrium in which firms fail to cooperate by taking actions—in this case raising the prices of video games—that would make them all better off. Firms have an incentive to increase their profits by switching to a cooperative equilibrium of charging $10 more for video games by implicitly colluding to do so. Explicitly colluding by having firms’ executives meet and agree to raise prices is against the law in the United States and Europe. But implicit collusion in which firms signal to each other—perhaps by talking about their plans with journalists—that they intend to raise prices is a gray area of the law that governments may not take action against. The fact that the article states that the price increase was an “industry-wide effort” is an indication that video game firms may have implicitly colluded to raise video game prices by $10.

Measuring Changes in Income Inequality

As we discuss in Chapter 17, there are several complications in accurately measuring changes in the distribution of income over time. First, people will not typically remain in the same place in the income distribution their whole lives. Instead, their incomes are likely to fluctuate, moving them up and down the income distribution. So comparing the distribution of income for the whole population at two points in time can give a misleading idea of how the incomes of particular individuals changed. Measuring income mobility can be difficult, however, because it entails tracking the incomes of individuals over time. Doing that requires specialized studies rather than relying on the more readily available government data we can use to track changes in the incomes of the whole population. 

Second, we are more interested in the income people have available to spend rather than the income they earn. Because people pay taxes on the incomes they receive and because many people receive transfer payments from the government, including unemployment insurance payments and Social Security payments, the income distribution is more equal if we measure it after taking into account the taxes people pay and the transfer payments they receive.

Finally, people earn income from a variety of sources in addition to wages and salaries, including dividends they receive from owning stock, capital gains they earn from selling a financial or other asset, and income they earn from owning a business such as a restaurant or dry cleaners. The income people at the top of the income distribution earn from owning a business can be particularly hard to measure because it depends on how the income is reported to the Internal Revenue Service, which depends in turn on changes in laws affecting how businesses are organized and how they pay taxes. Dealing with these measurement issues is particular important in determining how much the share of income earned by the top 1% of the income distribution has changed over time—an issue that has been the subject of much political debate.

Wojciech Kopczuk of Columbia University and Eric Zwick of the University of Chicago address these measurement issues in a new article in the Journal of Economic Perspectives. Even skimming the article makes clear just how difficult the measurement issues are. Click HERE to read the article.

Note that the article is part of a symposium on income and wealth inequality that appears in that issue of the journal. The other articles in the symposium are also worth reading. Articles that appear in the Journal of Economic Perspectives are frequently (but not always!) nontechnical summaries of research that can be read without knowledge of economics beyond the principles course. 

Does the U.S. Economy Need Another Government Stimulus Package?

In an opinion column on, Michael Strain of the American Enterprise Institute argues that Congress should pass another stimulus package to supplement the $1.8 trillion Coronavirus Aid, Relief, and Economic Security Act that Congress passed and President Trump signed into law in March. His proposal would involve an additional $1 trillion in spending.

Does Automation Lead to Permanent Job Losses?

This post on the Federal Reserve Bank of St. Louis’s Page One blog discusses how the belief that automation can lead to permanent job losses is an example of the “lump of labor” fallacy. Click HERE to read the article.
