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.

One of the key issues in monetary policy—dating back decades—is whether policy should be governed by a rule or whether the members of the Federal Open Market Committee (FOMC) should make “data-driven” decisions. Currently, the FOMC believes that the best approach is to let macroeconomic data drive decisions about the appropriate target for the federal funds rate rather than to allow a policy rule to determine the target.

In its most recent Monetary Policy Report to Congress, the Fed’s Board of Governors noted that policy rules “can provide useful benchmarks for the consideration of monetary policy. However, simple rules cannot capture all of the complex considerations that go into the formation of appropriate monetary policy, and many practical considerations make it undesirable for the FOMC to adhere strictly to the prescriptions of any specific rule.” We discuss the debate over monetary policy rules—sometimes described as the debate over “rules versus discretion” in conducting policy—in Macroeconomics, Chapter 15, Section 15.5 (Economics, Chapter 25, Section 25.5.)

Probably the best known advocate of the Fed relying on policy rules is John Taylor of Stanford University. The Taylor rule for monetary policy begins with an estimate of the value of the real federal funds rate, which is the federal funds rate—adjusted for inflation—that would be consistent with real GDP being equal to potential real GDP in the long run. With real GDP equal to potential real GDP, cyclical unemployment should be zero, and the Fed will have attained its policy goal of maximum employment, as the Fed defines it.

According to the Taylor rule, the Fed should set its current federal funds rate target equal to the sum of the current inflation rate, the equilibrium real federal funds rate, and two additional terms. The first of these terms is the inflation gap—the difference between current inflation and the target rate (currently 2 percent, as measured by the percentage change in the personal consumption expenditures (PCE) price index; the second term is the output gap—the percentage difference of real GDP from potential real GDP. The inflation gap and the output gap are each given “weights” that reflect their influence on the federal funds rate target. With weights of one-half for both gaps, we have the following Taylor rule:

Federal funds rate target = Current inflation rate + Equilibrium real federal funds rate + (1/2 × Inflation gap) + (1/2 × Output gap).

So when the inflation rate is above the Fed’s target rate, the FOMC will raise the target for the federal funds rate. Similarly, when the output gap is negative—that is, when real GDP is less than potential GDP—the FOMC will lower the target for the federal funds rate. In calibrating this rule, Taylor assumed that the equilibrium real federal funds rate is 2 percent and the target rate of inflation is 2 percent. (Note that the Taylor rule we are using here was the one Taylor first proposed in 1993. Since that time, Taylor and other economists have also analyzed other similar rules with, for instance, an assumption of a lower equilibrium real federal funds rate.)

The following figure shows the level of the federal funds rate that would have occurred if the Fed had strictly followed the original Taylor rule (the blue line) and the actual federal funds rate (the red line). The figure indicates that because during many years the two lines are close together, the Taylor rule does a reasonable job of explaining Federal Reserve policy. There are noticeable exceptions, however, such as the period of high inflation that began in the spring of 2021. During that period, the Taylor rule indicates that the FOMC should have begun raising its target for the federal funds rate earlier and raised it much higher than it did.

Taylor has presented a number of arguments in favor of the Fed relying on a rule in conducting monetary policy, including the following:

  1. A simple policy rule (such as the Taylor rule) makes it easier for households, firms, and investors to understand Fed policy.
  2. Conducting policy according to a rule makes it less likely that households, firms, and investors will be surprised by Fed policy.
  3. Fed policy is less likely to be subject to political pressure if it follows a rule: “If monetary policy appears to be run in an ad hoc and complicated way rather than a systematic way, then politicians may argue that they can be just as ad hoc and interfere with monetary policy decisions.”
  4. Following a rule makes it easier to hold the Fed accountable for policy errors.

The Fed hasn’t been persuaded by Taylor’s arguments, preferring its current data-driven approach. In setting monetary policy, the members of the FOMC believe in the importance of being forward looking, attempting to take into account the future paths of inflation and unemployment. But committee members can struggle to accurately forecast inflation and unemployment. For instance, at the time of the June 2021 meeting of the FOMC, inflation had already risen above 4%. Nevertheless, committee members forecast that inflation in 2022 would be 2.1%. Inflation in 2022 turned out to be much higher—6.6%.

To succeed with a data-driven approach to policy, members of the FOMC must be able to correctly interpret the importance of new data on economic variables as it becomes available and also accurately forecast the effects of policy changes on key variables, particularly unemployment and inflation. How do the committee members approach these tasks? To some extent they rely on formal economic models, such as those developed by the economists on the committee’s staff. But, judging by their speeches and media interviews, committee members also rely on qualitative analysis in interpreting new data and in forming their expectations of how monetary policy will affect the economy.

In recent years, generative artificial intelligence (AI) and machine learning (ML) programs have made great strides in analyzing large data sets. Should the Fed rely more heavily on these programs in conducting monetary policy? The Fed is currently only in the beginning stages of incorporating AI into its operations. In 2024, the Fed appointed a Chief Artificial Intelligence Officer (CAIO) to coordinate its AI initiatives. Initially, the Fed has used AI primarily in the areas of supervising the payment system and promoting financial stability. AI has the ability to quickly analyze millions of financial transactions to identify those that may be fraudulent or may not be in compliance with financial and banking regulations. How households, firms, and investors respond to Fed policies is an important part of how effective the policies will be. The Fed staff has used AI to analyze how financial markets are likely to react to FOMC policy announcements.

The Central Bank of Canada has gone further than the Fed in using AI. According to Tiff Macklem, the Governor of the Bank of Canada, AI is used to:

• forecast inflation, economic activity and demand for bank notes
• track sentiment in key sectors of the economy
• clean and verify regulatory data
• improve efficiency and de-risk operations

Will central banks begin to use AI to carry out the key activity of setting policy interest rates, such as the federal funds rate in the United States? AI has the potential to adjust the federal funds rate more promptly than the members of the FOMC are able to do in their eight yearly meetings. Will it happen? At this point, generative AI and ML models are not capable of taking on that responsibility. In addition, as noted earlier, Taylor and other supporters of rules-based policies have argued that simple rules are necessary for the public to understand Fed policy. AI generated rules are likely to be too complex to be readily understood by non-specialists.

It’s too early in the process of central banks adopting AI in their operations to know the eventual outcome. But AI is likely to have a significant effect on central banks, just as it is already affecting many businesses.

A Disagreement between Fed Chair Powell and Fed Governor Waller over Monetary Policy, and Can President Trump Replace Powell?

This post discusses two developments this week that involve the Federal Reserve. First, we discuss the apparent disagreement between Fed Chair Jerome Powell and Fed Governor Christopher Waller over the best way to respond to the Trump Administration’s tariff increases. As we discuss in this blog post and in this podcast, in terms of the aggregate demand and aggregate supply model, a large unexpected increase in tariffs results in an aggregate supply shock to the economy, shifting the short-run aggregate supply curve (SRAS) to the left. The following is Figure 13.7 from Macroeconomics (Figure 23.7 from Economics) and illustrates the effects of an aggregate supply shock on short-run macroeconomic equilibrium.

Although the figure shows the effects of an aggregate supply shock that results from an unexpected increase in oil prices, using this model, the result is the same for an aggregate supply shock caused by an unexpected increase in tariffs. Two-thirds of U.S. imports are raw materials, intermediate goods, or capital goods, all of which are used as inputs by U.S. firms. So, in both the case of an increase in oil prices and in the case of an increase in tariffs, the result of the supply shock is an increase in U.S. firms’ production costs. This increase in costs reduces the quantity of goods firms will supply at every price level, shifting the SRAS curve to the left, as shown in panel (a) of the figure. In the new macroeconomic equilibrium, point B in panel (a), the price level increases and the level of real GDP declines. The decline in real GDP will likely result in an increase in the unemployment rate.

An aggregate supply shock poses a policy dilemma for the Fed’s policymaking Federal Open Market Committee (FOMC). If the FOMC responds to the decline n real GDP and the increase in the unemployment rate with an expansionary monetary policy of lowering the target for the federal funds rate, the result is likely to be a further increase in the price level. Using a contractionary monetary policy of increasing the target for the federla funds rate to deal with the rising price level can cause real GDP to fall further, possibly pushing the economy into a recession. One way to avoid the policy dilemma from an aggregate supply shock caused by an increase in tariffs is for the FOMC to “look through”—that is, not respond—to the increase in tariffs. As panel (b) in the figure shows, if the FOMC looks through the tariff increase, the effect of the aggregate supply shock can be transitory as the economy absorbs the one-time increase in the price level. In time, real GDP will return to equilibrium at potential real GDP and the unemployment rate will fall back to the natural rate of unemployment.

On Monday (April 14), Fed Governor Christopher Waller in a speech to the Certified Financial Analysts Society of St. Louis made the argument for either looking through the macroeconomic effects of the tariff increase—even if the tariff increase turns out to be large, which at this time is unclear—or responding to the negative effects of the tariffs increases on real GDP and unemployment:

“I am saying that I expect that elevated inflation would be temporary, and ‘temporary’ is another word for ‘transitory.’ Despite the fact that the last surge of inflation beginning in 2021 lasted longer than I and other policymakers initially expected, my best judgment is that higher inflation from tariffs will be temporary…. While I expect the inflationary effects of higher tariffs to be temporary, their effects on output and employment could be longer-lasting and an important factor in determining the appropriate stance of monetary policy. If the slowdown is significant and even threatens a recession, then I would expect to favor cutting the FOMC’s policy rate sooner, and to a greater extent than I had previously thought.”

In a press conference after the last FOMC meeting on March 19, Fed Chair Jerome Powell took a similar position, arguing that: “If there’s an inflation that’s going to go away on its own, it’s not the correct response to tighten policy.” But in a speech yesterday (April 16) at the Economic Club of Chicago, Powell indicated that looking through the increase in the price level resulting from a tariff increase might be a mistake:

“The level of the tariff increases announced so far is significantly larger than anticipated. The same is likely to be true of the economic effects, which will include higher inflation and slower growth. Both survey- and market-based measures of near-term inflation expectations have moved up significantly, with survey participants pointing to tariffs…. Tariffs are highly likely to generate at least a temporary rise in inflation. The inflationary effects could also be more persistent…. 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.”

In a discussion following his speech, Powell argued that tariff increases may disrupt global supply chains for some U.S. industries, such as automobiles, in way that could be similar to the disruptions caused by the Covid pandemic of 2020. As a result: “When you think about supply disruptions, that is the kind of thing that can take time to resolve and it can lead what would’ve been a one-time inflation shock to be extended, perhaps more persistent.” Whereas Waller seemed to indicate that as a result of the tariff increases the FOMC might be led to cut its target for the federal funds sooner or to larger extent in order to meet the maximum employment part of its dual mandate, Powell seemed to indicate that the FOMC might keep its target unchanged longer in order to meet the price stability part of the dual mandate.

Powell’s speech caught the notice of President Donald Trump who has been pushing the FOMC to cut its target for the federal funds rate sooner. An article in the Wall Street Journal, quoted Trump as posting to social media that: “Powell’s termination cannot come fast enough!” Powell’s term as Fed chair is scheduled to end in May 2026. Does Trump have the legal authority to replace Powell earlier than that? As we discuss in Macroeconomics, Chapter 27 (Economics Chapter 17), according to the Federal Reserve Act, once a Fed chair is notimated to a four-year term by the president (President Trump first nominated Powell to be chair in 2017 and Powell took office in 2018) and confirmed by the Senate, the president cannot remove the Fed chair except “for cause.” Most legal scholars argue that a president cannot remove a Fed chair due to a disagreement over monetary policy.

Article I, Section II of the Constitution of the United States states that: “The executive Power shall be vested in a President of the United States of America.” The ability of Congress to limit the president’s power to appoint and remove heads of commissions, agencies, and other bodies in the executive branch of government—such as the Federal Reserve—is not clearly specified in the Constitution. In 1935, a unanimous Supreme Court ruled in the case of Humphrey’s Executor v. United States that President Franklin Roosevelt couldn’t remove a member of the Federal Trade Commission (FTC) because in creating the FTC, Congress specified that members could only be removed for cause. Legal scholars have presumed that the ruling in this case would also bar attempts by a president to remove members of the Fed’s Board of Governors because of a disagreement over monetary policy.

The Trump Administration recently fired a member of the National Labor Relations Board and a member of the Merit Systems Protection Board. The members sued and the Supreme Court is considering the case. The Trump Adminstration is asking the Court to overturn the Humphrey’s Executor decision as having been wrongly decided because the decision infringed on the executive power given to the president by the Constitution. If the Court agrees with the administration and overturns the precdent established by Humphrey’s Executor, would President Trump be free to fire Chair Powell before Powell’s term ends? (An overview of the issues involved in this Court case can be found in this article from the Associated Press.)

The answer isn’t clear because, as we’ve noted in Macroeconomics, Chapter 14, Section 14.4, Congress gave the Fed an unusual hybrid public-private structure and the ability to fund its own operations without needing appropriations from Congress. It’s possible that the Court would rule that in overturning Humphrey’s Executor—if the Court should decide to do that—it wasn’t authorizing the president to replace the Fed chair at will. In response to a question following his speech yesterday, Powell seemed to indicate that the Fed’s unique structure might shield it from the effects of the Court’s decision.

If the Court were to overturn its ruling in Humphrey’s Executor and indicate that the ruling did authorize the president to remove the Fed chair, the Fed’s ability to conduce monetary policy independently of the president would be seriously undermined. In Macroeconomics, Chapter 17, Section 17.4 we review the arguments for and against Fed independence. It’s unclear at this point when the Court might rule on the case.

Solved Problem: Congestion Pricing and the Price Elasticity of Demand

Supports: Microeconomics and Economics, Chapter 6, and Essentials of Economics, Chapter 7, Section 7.5-7.7

ChatGTP-4o image of cars in the Lincoln Tunnel, which connects New Jersey with midtown Manhattan.

In January 2025, New York City began enforcing congestion pricing in the borough of Manhattan south of 60th Street—the congestion relief zone. The Metropolitan Transportation Authority (MTA) in New York collects a toll from a vehicle entering that zone either automatically using the vehicle’s E-ZPass transponder or by reading the vehicle’s license plate and mailing a bill to the vehicle’s owner. Nobel Laureate William Vickrey of Columbia University first proposed congestion pricing in the 1950s as a way to deal with the negative externalities from traffic congestion. Congestion pricing acts as a Pigovian tax that internalizes the external costs drivers generate by using streets in congested areas. (We discuss Pigovian taxes in Microeconomics and Economics, Chapter 5, Section 5.3, and in Essentials of Economics, Chapter 4, Section 4.3.)

The New York City congestion toll is somewhat complex, varying according to the type of vehicle and how the vehicle enters the area in which the toll applies. The congestion toll fora car entering Manhattan through the Lincoln Tunnel on a weekday between 5 am and 9 pm is $6.00 on top of the existing toll of $16.06. In January 2025, the volume of cars driving through the Lincoln Tunnel declined by 8 percent during the weekday hours of 5 am to 9 pm. According to an article in Crain’s New York Business, the number of vehicles entering the congestion relief zone compared with the same month in the previous year declined by 8 percent in January, 12 percent in February, and 13 percent in March.

  1. From the information given, can we determine the price elasticity of demand for entering Manhattan by driving though the Lincoln Tunnel during weekdays from 5am to 9am? Briefly explain.
  2. Suppose someone makes the following claim: “Because the quantity of cars using the Lincoln Tunnel has declined by 8 percent, we know that the MTA must have collected less revenue from cars using the tunnel than before the congestion toll was imposed.” Briefly explain whether you agree.
  3. Is the pattern of increasing percentage declines in vehicle traffic in the congestion relief zone each month from January to March what we would expect? Be sure your answer refers to concepts related to the price elasticity of demand.

Step 1: Review the chapter material. This problem is about the price elasticity of demand, so you may want to review Chapter 6, Sections 6.1-6.4. 

Step 2: Answer part (a) by explaining whether from the information given we can determine the price elasticity of demand for entering Manhattan by driving through the Lincoln Tunnel. We do have sufficient information to determine the price elasticity, provided that nothing else that would affect the demand for driving through the Lincoln Tunnel changed during January. We’re told the percentage change in the quantity demand, so we need only to calculate the percentage change in the price to determine the price elasticity. The change in the price is the $6 congestion toll. The average of the price before and the price after the toll is imposed is ($16.06 + $22.06) = $19.06. Therefore, the percentage change in the price is ($6/$19.06) × 100 = 31.5 percent. The price elasticity of demand is equal to the percentage change in quantity dmanded divided by the percentage change in price: –6%/31.5% = –0.3. Because this value is less than 1 in absolute value, we can conclude that the demand for driving through the Lincoln Tunnel is price inelastic.

Step 3: Answer part (b) by explaining whether because the quantity of cars driving through the Lincoln Tunnel has declined the MTA must have collected less revenue from cars using the tunnel. As shown in Section 6.3 of the textbook, total revenue received will fall after a price increase only if demand is price elastic. In this case, demand is price inelastic, so the total revenue the MTA collects from cars using the Lincoln Tunnel will rise, not fall.

Step 3: Answer part (c) by explaining whether the pattern of increasing percentage declines in vehicle traffic in the congestion relief zone is one we would expect. In Section 6.2, we see that the passage of time is one of the determinants of the price elasticity of demand. The more time that passes, the more price elastic the demand for a product becomes. In other words, the longer the time that people have to adjust to the congestion toll—by, for instance, taking a bus rather than driving through the Lincoln Tunnel in a car—the more likely it is that people will decide not to drive into the congestion relief zone. So, it is not surprising that the number of vehicles entering the congestion relief zone declined by a greater percentage each month from January to March.

The U.S.-China Trade War Illustrated in Two Graphs from the Peterson Institute

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.)

CPI Inflation Slows More than Expected

Image generated by Chat-GTP-4o

Today (April 10), the Bureau of Labor Statistics (BLS) released its monthly report on the consumer price index (CPI). The following figure compares headline inflation (the blue line) and core inflation (the red line).

  • The headline inflation rate, which is measured by the percentage change in the CPI from the same month in the previous year, was 2.4 percent in March—down from 2.8 percent in February. 
  • The core inflation rate, which excludes the prices of food and energy, was 2.8 percent in March—down from 3.1 percent in February. 

Both headline inflation and core inflation were below what economists surveyed had expected.

In the following figure, we look at the 1-month inflation rate for headline and core inflation—that is the annual inflation rate calculated by compounding the current month’s rate over an entire year. Calculated as the 1-month inflation rate, headline inflation (the blue line) fell sharply from 2.6 percent in March to –0.6 percent—that is, the economy experienced deflation in March. Core inflation (the red line) decreased from 2.6 percent in February to 0.7 percent in March.

Overall, considering 1-month and 12-month inflation together, inflation slowed significantly in March. Of course, it’s important not to overinterpret the data from a single month. The figure shows that 1-month inflation rate is particularly volatile. Also note that the Fed uses the personal consumption expenditures (PCE) price index, rather than the CPI, to evaluate whether it is hitting its 2 percent annual inflation target.

There’s been considerable discussion in the media about continuing inflation in grocery prices. In the following figure the blue line shows inflation in the CPI category “food at home,” which is primarily grocery prices. Inflation in grocery prices was 2.4 percent in March, up from 1.8 percent in February, but still far below the peak of 13.6 percen in August 2022. Although, on average, grocery price inflation has been low over the past 18 months, there have been substantial increases in the prices of some food items. For instance, egg prices—shown by the red line—increased by 108.1 percent in March. But, as the figure shows, egg prices are usually quite volatile month-to-month, even when the country is not dealing with an epidemic of bird flu.

To better estimate the underlying trend in inflation, some economists look at median inflation and trimmed mean inflation.

  • Median inflation is calculated by economists at the Federal Reserve Bank of Cleveland and Ohio State University. If we listed the inflation rate in each individual good or service in the CPI, median inflation is the inflation rate of the good or service that is in the middle of the list—that is, the inflation rate in the price of the good or service that has an equal number of higher and lower inflation rates. 
  • Trimmed-mean inflation drops the 8 percent of goods and services with the highest inflation rates and the 8 percent of goods and services with the lowest inflation rates. 

The following figure shows that 12-month trimmed-mean inflation (the blue line) was 3.0 percent in March, down from 3.1 percent in February. Twelve-month median inflation (the red line) also declined slightly from 3.1 percent in February to 3.0 percent in March.

The following figure shows 1-month trimmed-mean and median inflation. One-month trimmed-mean inflation fell from 3.3 percent in February to 2.6. percent in March. One-month median inflation increased from 3.5 percent in February to 4.1 percent in March. These data are noticeably higher than either the 12-month measures for these variables or the 1-month and 12-month measures of headline and core inflation. Again, though, all 1-month inflation measures can be volatile.

There isn’t much sign in today’s CPI report that the tariffs recently imposed by the Trump Administration have affected retail prices. President Trump announced yesterday that many of the tariffs would be suspended for at least 90 days, although the across-the-board tariff of 10 percent remains in place and a tariff of 145 percent has been imposed on goods imported from China. It would surprising if those tariff increases don’t begin to have at least some effect on the CPI over the next few months. As we noted in this post from earlier in the month, Tariffs pose a dilemma for the Fed, because tariffs have the effect of both increasing the price level and reducing real GDP and employment.

What are the implications of this CPI report for the actions the Federal Reserve’s policymaking Federal Open Market Committee (FOMC) may take at its next two meetings? Investors who buy and sell federal funds futures contracts still do not expect that the FOMC will cut its target for the federal funds rate at its next two meetings. (We discuss the futures market for federal funds in this blog post.) Today, investors assigned only a 29.9 percent probability that the Fed’s policymaking Federal Open Market Committee (FOMC) will cut its target from the current 4.25 percent to 4.50 percent range at its meeting on May 6–7. Investors assigned a probability of 85.2 percent that the FOMC would cut its target after its meeting on June 17–18 by at least 0.25 percent (or 25 basis points).

By the time the FOMC meets again in early May we may have more data on the effects the tariffs are having on the economy.

Solved Problem: Mickey v. Cost Curves

a.

b.

Solving the Problem
Step 1: Review the chapter material. This problem is about drawing and interpreting cost curves, so you may want to review Chapter 11, Section 11.5, “Graphing Cost Curves.”

Step 2: Answer part a. by explaining whether there are any errors in the cost curves shown in the image in a. No wonder Mickey is confused! This figure has multiple errors:

  1. It’s an error to have the ATC and AVC curves cross. The unlabeled curve at the bottom is supposed to be AFC. We know that if a firm has fixed costs, then the ATC and AVC curves will get closer and closer as the quantity increases and AFC becomes smaller and smaller. But because AFC will never decline to zero, ATC and AVC can’t be equal at any quantity.
  2. The second error is related to the first error. We know that the MC and ATC curves should intersect at the quantity at which ATC is at a minimum. In this figure, the MC curve intersects the ATC curve at a quantity that is larger than the quantity at which ATC recaches a minimum.
  3. The third error is related to the first two errors. The relationship between the three average cost curves should be ATC = AVC + AFC at every quantity. In this figure the relationship doesn’t hold at any quantity.
  4. Finally, there is a dotted line from the point where the (unlabeled) AFC curve intersects with the MC curve down to the Q-axis. But that point has no economic significance.

Step 3: Answer part b. by explaining whether there are any errors in the cost curves shown in image b. Mickey can rest easy with these cost curve because, although the figure seems to be only partially finished, all of the cost curves are correctly drawn. The MC curve correctly intersects the AVC curve at the quantity at which the AVC curve is at a minimum. The instructor could finish the figure by labeling the bottom curve as AFC and by drawing an ATC curve above the AVC curve, with the ATC curve intersecting the MC curve at the quantity at which the ATC curve is at a minimum.

What Happened after Smoot-Hawley?

Congressman Willis Hawley of Oregon and Senator Reed Smoot of Utah (Photo from the U.S. Library of Congress via the Wall Street Journal)

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 on Tariffs

Surprisingly Strong Jobs Report

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.
