The model of demand and supply is useful in analyzing the effects of tariffs. In Chapter 9, Section 9.4 (Macroeconomics, Chapter 7, Section 7.4) we analyze the situation—for instance, the market for sugar—when U.S. demand is a small fraction of total world demand and when the U.S. both produces the good and imports it.
In this problem, we look at the television market and assume that no domestic firms make televisions. (A few U.S. firms assemble limited numbers of televisions from imported components.) As a result, the supply of televisions consists entirely of imports. Beginning in April, the Trump administration increased tariff rates on imports of televisions from Japan, South Korea, China, and other countries. Tariffs are effectively a tax on imports, so we can use the analysis in Chapter 4, Section 4.4, “The Economic Effect of Taxes” to analyze the effect of tariffs on the market for televisions.
Use a demand and supply graph to illustrate the effect of an increased tariff on imported televisions on the market for televisions in the United States. Be sure that your graph shows any shifts of the curves and the equilibrium price and quantity of televisions before and after the tariff increase.
An article in the Wall Street Journal discussed the effect of tariffs on the market for used goods. Use a second demand and supply graph to show the effect of a tariff on imports of new televisions on the market in the United States for used televisions. Assume that no used televisions are imported and that the supply curve for used televisions is upward sloping.
Solving the Problem Step 1: Review the chapter material. This problem is about the effect of a tariff on an imported good on the domestic market for the good. Because a tariff is a like a tax, you may want to review Chapter 4, Section 4.4, “The Economic Effect of Taxes.”
Step 2: Answer part a. by drawing a demand and supply graph of the market for televisions in the United States that illustrates the effect of an increased tariff on imported televisions. The following figure shows that a tariff causes the supply curve of televisions to shift up from S1 to S2. As a result, the equilibrium price increases from P1 to P2, while the equilibrium quantity falls from Q1 to Q2.
Step 2: Answer part b. by drawing a demand and supply graph of the market for used televisions in the United States that illustrates the effect on that market of an increased tariff on imports of new televisions. Although the tariff on imported televisions doesn’t directly affect the market for used televisions, it does so indirectly. As the article from the Wall Street Journal notes, “Today, in the tariff era, demand for used goods is surging.” Because used televisions are substitutes for new televisions, we would expect that an increase in the price of new televisions would cause the demand curve for used televisions to shift to the right, as shown in the following figure. The result will be that the equilibrium price of used televisions will increase from P1 to P2, while the equilibrium quantity of used televisions will increase from Q1 to Q2.
To summarize: A tariff on imports of new televisions increases the price of both new and used televisions. It decreases the quantity of new televisions sold but increases the quantity of used televisions sold.
Glenn Hubbard and Tony O’Brien begin by examining the challenges facing the Federal Reserve due to incomplete economic data, a result of federal agency shutdowns. Despite limited information, they note that growth remains steady but inflation is above target, creating a conundrum for policymakers. The discussion turns to the upcoming appointment of a new Fed chair and the broader questions of central bank independence and the evolving role of monetary policy. They also address the uncertainty surrounding AI-driven layoffs, referencing contrasting academic views on whether artificial intelligence will complement existing jobs or lead to significant displacement. Both agree that the full impact of AI on productivity and employment will take time to materialize, drawing parallels to the slow adoption of the internet in the 1990s.
The podcast further explores the recent volatility in stock prices of AI-related firms, comparing the current environment to the dot-com bubble and questioning the sustainability of high valuations. Hubbard and O’Brien discuss the effects of tariffs, noting that price increases have been less dramatic than expected due to factors like inventory buffers and contractual delays. They highlight the tension between tariffs as tools for protection and revenue, and the broader implications for manufacturing, agriculture, and consumer prices. The episode concludes with reflections on the importance of ongoing observation and analysis as these economic trends evolve.
In today’s episode, Glenn Hubbard and Tony O’Brien take on three timely topics that are shaping economic conversations across the country. They begin with a discussion on tariffs, exploring how recent trade policies are influencing prices, production decisions, and global relationships. From there, they turn to the independence of the Federal Reserve Bank, explaining why central bank autonomy is essential for sound monetary policy and what risks arise when political pressures creep in. Finally, they shed light on the Bureau of Labor Statistics (BLS), unpacking how its data collection and reporting play a vital role in guiding both public understanding and policymaking.
It’s a lively and informative conversation that brings clarity to complex issues—and it’s perfect for students, instructors, and anyone interested in how economics connects to the real world.
Recently, Glenn appeared on the Firing Line program to discuss tariffs. Coincidentally, Margaret Hoover, the host of the program, is the great-granddaughter of Herbert Hoover. Herbert Hoover was the president who signed the Smoot-Hawley Tariff bill in 1930. We discussed the Smoot-Hawley Tariff in a recent blog post.

The tit-for-tat tariff increases the U.S. and Chinese governments have levied on each other’s imports have reached dizzying heights today (April 11). The United States has imposed a tariff rate of 134.7 percent on imports from China, while China has imposed a tariff rate of 147.6 percent on imports from the United States. On all other countries—the rest of the world (ROW)—the United States imposes an average tariff rate of 10.5 percent, which is a sharp increase reflecting the Trump Administration’s imposition of a tariff of at least 10 percent on all countries. The government of China imposes a tariff rate of 6.5 percent on the ROW.
The Peterson Institute for International Economics (PIIE) is a think tank located in Washington, DC. Chad Brown, a senior fellow at PIIE, has created two charts that dramatically illustrate the current state of the U.S.-China trade war. The first chart shows the changes since the beginning of the first Trump Administration in 2017 in the tariff rates the countries have imposed on each other’s imports.
The second chart shows the percentage of each country’s exports to the other country that have been subject to tariffs. As of today, 100 percent of each country’s exports are subject to the other country’s tariffs.
Finally, we repeat a figure from an earlier blog post showing changes over time in the average tariff rate the United States levies on imports. The value for 2025 of 16.5 percent is an estimate by the Tax Foundation and assumes that the tariff rates that the Trump Administration announced on April 2 go into force, although the rates are currently suspended for 90 days—apart from those imposed on China. (An average tariff rate of 16.5 percent would be the highest levied by the United States since 1937.)

Until last week, the most famous example of the United States dramatically increasing tariffs on foreign imports was the Smoot-Hawley Tariff, which was passed by Congress and signed into law by President Herbet Hoover in June 1930. The website of the U.S. Senate describes the bill as “among the most catastrophic acts in congressional history.”
Did the Smoot-Hawley Tariff cause the Great Depression? According to the National Bureau of Economic Research’s business cycle dates, the Great Depression began in August 1929, well before the passage of Smoot-Hawley. By June 1930, industrial production had already declined in the United States by more than 17 percent. So, even if the downturn had ended at that point it would still have been severe. The contraction phase of the Depression continued until March 1933, by which time industrial production had declined more than 51 percent. That was the largest decline in U.S. history
If Smoot-Hawley didn’t cause the Depression, did it contribute to the Depression’s length and severity? Most economists believe that it did by contributing to the collapse of the global trading system, thereby reducing U.S. exports, aggregate demand, and production and employment.
Some years ago, Tony wrote an overview of Smoot-Hawley that discusses its causes and effects in more detail. A key question in assessing the effects of Smoot-Hawley is the extent to which key trading partners of the United States raised their tariffs in retaliation. The clearest case is Canada, which in 1930 was the leading trading partner of the United States. Canadian Prime Minister William Lyon Mackenzie King and the Liberal Party significantly raised tariffs on U.S. imports in explicit retaliation for Smoot-Hawley. This journal article that Tony co-wrote with two Lehigh colleagues discusses the empirical evidence for this conclusion. (The link takes you to the Jstor site. You may be able to read or download the whole article by clicking on the link on that page and entering the name of your college or university.)
The Trump Administration seems to be attempting a major reordering of the global trading system. A Canadian prime minister in the 1930s tried something similar. Richard Bedford Bennett became prime minister after his Conservative Party defeated Mackenzie King’s Liberal Party in the 1935 Canadian election. Bennett hoped to replace the U.S. market with the markets in England and other countries in the British Commonwealth. He argued that, taken together, the Commonwealth countries had sufficient resources to be largely self-sufficient and need not rely on trade with non-Commonwealth countries. In the end, Bennett was unsuccessful for reasons that Tony and a Lehigh colleague explore in this journal article.

Douglas Irwin, a professor of economics at Dartmouth College, may be the leading historian of international trade in the United States today. Irwin has posted at this link a useful overview of the economics of tariffs.
Irwin’s feed on X offers day-to-day commentary on current developments in the Trump Administration’s rapidly changing tariff policies. At the top of his X feed, you can find a free download of Clashing over Commerce, his 2019 history of U.S. foreign trade policy. At 862 pages, the book is the most thorough and comprehensive account available of the long-running political disputes in the United States over foreign trade.
As we’ve noted in earlier posts, according to the usually reliable GDPNow forecast from the Federal Reserve Bank of Atlanta, real GDP in the first quarter of 2025 will decline by 2.8 percent. This morning (April 4), the Bureau of Labor Statistics (BLS) released its “Employment Situation” report (often called the “jobs report”) for March. The data in the report show no sign that the U.S. economy is in a recession. We should add two caveats, however: 1. The effects of the unexpectedly large tariff increases announced this week by the Trump Administration are not reflected in the data from this report, and 2. at the beginning of a recession the data in the jobs report can be subject to large revisions.
The jobs report has two estimates of the change in employment during the month: one estimate from the establishment survey, often referred to as the payroll survey, and one from the household survey. As we discuss in Macroeconomics, Chapter 9, Section 9.1 (Economics, Chapter 19, Section 19.1), many economists and Federal Reserve policymakers believe that employment data from the establishment survey provide a more accurate indicator of the state of the labor market than do the household survey’s employment data and unemployment data. (The groups included in the employment estimates from the two surveys are somewhat different, as we discuss in this post.)
According to the establishment survey, there was a net increase of 228,000 jobs during March. This increase was well above the increase of 140,000 that economists had forecast. Somewhat offsetting this unexpectedly large increase was the BLS revising downward its previous estimates of employment in January and February by a combined 48,000 jobs. (The BLS notes that: “Monthly revisions result from additional reports received from businesses and government agencies since the last published estimates and from the recalculation of seasonal factors.”) The following figure from the jobs report shows the net change in payroll employment for each month in the last two years.
The unemployment rate rose slightly to 4.2 percent in March from 4.1 percent in February. As the following figure shows, the unemployment rate has been remarkably stable in recent months, staying between 4.0 percent and 4.2 percent in each month since May 2024. In March, the members of the Federal Open Market Committee (FOMC) forecast that the unemployment rate for 2025 would average 4.4 percent.
As the following figure shows, the monthly net change in jobs from the household survey moves much more erratically than does the net change in jobs from the establishment survey. As measured by the household survey, there was a net increase of 201,000 jobs in March, following a sharp decrease of 588,000 jobs in February. In any particular month, the story told by the two surveys can be inconsistent with employment increasing in one survey while falling in the other. This month, however, both surveys showed roughly the same net job increase. (In this blog post, we discuss the differences between the employment estimates in the two surveys.)
One concerning sign in the household survey is the fall in the employment-population ratio for prime age workers—those aged 25 to 54. The ratio declined from 80.5 percent in February to 80.4 percent in March. Although the prime-age employment-population is still high relative to the average level since 2001, it’s now well below the high of 80.9 percent in mid-2024. Continuing declines in this ratio would indicate a significant softening in the labor market.
It’s unclear how many federal workers have been laid off since the Trump Administration took office. The establishment survey shows a decline in total federal government employment of 4,000 in March. However, the BLS notes that: “Employees on paid leave or receiving ongoing severance pay are counted as employed in the establishment survey.” It’s possible that as more federal employees end their period of receiving severance pay, future jobs reports may find a more significant decline in federal employment.
The establishment survey also includes data on average hourly earnings (AHE). As we noted in this post, many economists and policymakers believe the employment cost index (ECI) is a better measure of wage pressures in the economy than is the AHE. The AHE does have the important advantage of being available monthly, whereas the ECI is only available quarterly. The following figure shows the percentage change in the AHE from the same month in the previous year. The AHE increased 3.8 percent in March, down from 4.0 percent in February.
The following figure shows wage inflation calculated by compounding the current month’s rate over an entire year. (The figure above shows what is sometimes called 12-month wage inflation, whereas this figure shows 1-month wage inflation.) One-month wage inflation is much more volatile than 12-month wage inflation—note the very large swings in 1-month wage inflation in April and May 2020 during the business closures caused by the Covid pandemic. The March 1-month rate of wage inflation was 3.0 percent, up from 2.7 percent in February. Whether measured as a 12-month increase or as a 1-month increase, AHE is still increasing somewhat more rapidly than is consistent with the Fed achieving its 2 percent target rate of price inflation.
Taken by itself, today’s jobs report leaves the situation facing the Federal Reserve’s policy-making Federal Open Market Committee (FOMC) largely unchanged. There are some indications that the economy may be weakening, as shown by some of the data in the jobs report and by some of the data incorporated by the Atlanta Fed in its pessimistic nowcast of first quarter real GDP. But the Fed hasn’t yet brought inflation down to its 2 percent annual target.
Looming over monetary policy is the fallout from the Trump Administration’s implementation of unexpectedly large tariff increases. As we note in this blog post, a large unexpected increase in tariffs results in an aggregate supply shock to the economy. In terms of the basic aggregate demand and aggregate supply model that we discuss in Macroeconomics, Chapter 13 (Economics, Chapter 23), an unexpected increase in tariffs shifts the short-run aggregate supply curve (SRAS) to the left, increasing the price level and reducing the level of real GDP.
The effect of the tariffs poses a dilemma for the Fed. With inflation still running above the 2 percent annual target, additional upward pressure on the price level is unwelcome news. The dramatic decline in both stock prices and in the interest rate on the 10-Treasury note indicate that investors are concerned that the tariffs increases may push the U.S. economy into a recession. The FOMC can respond to the threat of a recession by cutting its target for the federal funds rate, but doing so runs the risk of pushing inflation higher.
In a speech today, Fed Chair Jerome Powell stated the following:
“We have stressed that it will be very difficult to assess the likely economic effects of higher tariffs until there is greater certainty about the details, such as what will be tariffed, at what level and for what duration, and the extent of retaliation from our trading partners. While uncertainty remains elevated, it is now becoming clear that the tariff increases will be significantly larger than expected. The same is likely to be true of the economic effects, which will include higher inflation and slower growth. The size and duration of these effects remain uncertain. While tariffs are highly likely to generate at least a temporary rise in inflation, it is also possible that the effects could be more persistent. Avoiding that outcome would depend on keeping longer-term inflation expectations well anchored, on the size of the effects, and on how long it takes for them to pass through fully to prices. Our obligation is to keep longer-term inflation expectations well anchored and to make certain that a one-time increase in the price level does not become an ongoing inflation problem.”
One indication of expectations of future cuts in the target for the federal funds rate comes from investors who buy and sell federal funds futures contracts. (We discuss the futures market for federal funds in this blog post.) The data from the futures market indicate that, despite the potential effects of the surprisingly large tariff increases, investors don’t expect that the FOMC will cut its target for the federal funds rate at its May 6–7 meeting. As shown in the following figure, investors assign a 58.4 percent probability to the committee keeping its target unchanged at 4.25 percent to 4.50 percent at that meeting.
It’s a different story if we look at the end of the year. As the following figure shows, investors now expect that by the end of the FOMC’s meeting on December 9-10, the committee will have implemented at least four 0.25 percentage point (25 basis points) cuts in its target range for the federal funds rate. Investors assign a probability of 75.8 percent that the target range will end the year 3.25 percent to 3.50 percent or lower. At their March meeting, FOMC members projected only two 25 basis point cuts this year—but that was before the announcement of the unexpectedly large tariff increases.

This afternoon (April 2), President Donald Trump announced a sweeping increase in tariff rates on imported goods. The increases were by far the largest since the Smoot-Hawley Tariff of 1930. The United States will impose 10 percent across-the-board tariff on all imports, with higher tariffs being imposed on individual countries. Taking into account earlier tariffs, Chinese imports will be subject to a 54 percent tariff. Imports from Vietnam will be subject to a 46 percent tariff, and imports from the countries in the European Union will be subject to a 20 percent tariff.
President Trump’s objectives in imposing the tariffs aren’t entirely clear because he and his advisers have emphasized different goals at different times. The most common objectives the president and his advisers have offered for the tariff increases are these three:
To increase the size of the U.S. manufacturing sector by raising the prices of imported manufactured goods.
To retaliate against barriers that other countries have raised against U.S. exports.
To raise revenue for the federal government.
The effects of the tariffs on the U.S. economy depend in part on whether foreign countries retaliate by raising their tariffs on imports from the United States and on whether, in the future, the president reduces tariffs in exchange for other countries reducing barriers to U.S. imports. For a background discussion of tariffs, see this post. Glenn and Tony discuss tariffs in this podcast, which was recorded on Friday afternoon (March 28). A discussion of the Smoot-Hawley Tariff can be found here.
The following Solved Problem looks at one aspect of the effects of a tariff increase.
Supports:Microeconomics and Economics, Chapter 6, Section 6.3.
Nearly every automobile assembled in the United States contains at least some imported parts. An article on axis.com made the following statement about the effect on U.S. automobile manufacturers of an increase in the tariff on imported auto parts: “If car prices [in the United States] go up, Americans will buy fewer of them, meaning less revenue ….” What assumption is the author of this article making about the demand for new automobiles in the United States?
Solving the Problem
Step 1: Review the chapter material. This problem is about the effect of price increases on a firm’s revenue, so you may want to review the section “The Relationship between Price Elasticity of Demand and Total Revenue.”
Step 2: Answer the question by explaining what must be true of the demand for new automobiles in the United States if an increase in automobile prices results in a decline in the revenue received by automobile producers. This section of Chapter 6 explains how the price elasticity of demand affects the revenue a firm receives following a price increase. A price increase, holding everything else constant that affects the demand for a good, always causes a decline in the quantity demanded. If demand is price inelastic, an increase in price will result in an increase in revenue because the percentage decline in quantity demanded will be smaller than the percentage increase in the price. If demand is price elastic, an increase in price will result in a decrease in revenue because the percentage decline in the quantity demanded will be larger than the percentage increase in price. We can conclude that the author of the article must be assuming that the demand for new automobiles in the United States is price elastic.
Please listen to a podcast discussion recorded just this past Friday between Glenn Hubbard and Tony O’Brien as they discuss tariffs and it’s impact on monetary policy. Also, check out the regular blog posts while on the site! So much has been happening and these posts helps both instructors and students integrate this discussion into their classroom.
Join authors Glenn Hubbard and Tony O’Brien as they discuss the impact of new tariff policies on trade but also on the larger economy. They delve into the Fed, monetary policy, and the impact on inflation. They also discuss some of the history back to when tariffs used to be a high proportion of government revenue and analyze the mix of products that are imported & exported by the US. Should the Fed change its current behavior due to the tariff environment?
