Authors Glenn Hubbard and Tony O’Brien look at the economic outlook given the current status of the presidential election. Will a divided government lead to economic prosperity or result in more gridlock? They discuss how much the President actually controls economic policy by setting the tone but that other instruments of our government likely have more effect in creating long-term growth in the Economy.

Glenn Hubbard and Tony O’Brien continue their podcast series with a first – hosing a guest – Penn State Economics Professor, James Tierney. We learn about the transition James had from an early return from spring break to now teaching hundreds of students exclusively online in response to the pandemic. Glenn and Tony also discuss with James the struggles of the housing market in a small college town like State College, PA. We also learn the reasons behind James becoming the founder of an adult Improv company in the State College-area and the impact it had on his teaching. Please listen and share!
Glenn Hubbard and Tony O’Brien continue their podcast series by spending just under 15 minutes discussing why it was so difficult for economists to see this pandemic and the associated economic downturn coming. Just as scientists lacked the indicators to see the pandemic coming, economists also didn’t have the tools available to see where the economy was headed even though some early signs were present. Please listen and SHARE with your students.
Glenn Hubbard and Tony O’Brien continued their podcast series by spending about 15 minutes discussing the impact of the Pandemic on the Mom and Pop Businesses across the country. Much of the stimulus package has been developed to save small business but might it be too late or just not enough? Please listen and SHARE with your students.

Why Do Economists Have Trouble Predicting Recessions?
During the 2008 financial crisis,Queen Elizabeth of England visited the London School of Economics and famously asked the economists present, “Why did nobody notice it?” The queen is not alone in wondering why economists seem unable to predict when an economic crisis or financial crisis will hit.
There are three main reasons recessions are difficult for economists to predict:
Business Cycles are Not Uniform Although economists and policymakers often refer to the “business cycle,” in fact the recurring periods of economic expansion and economic contraction are not of uniform length or severity, so they do not resemble a sine wave from mathematics or other regular pattern. Because economic expansions have no set length, there is no reason to predict that an economic expansion that has lasted for a particular period of time will soon end in a recession.
Leading Economic Indicators are Not Reliable Economists haven’t found a consistent relationship between changes in any economic variable and later changes in real GDP and employment that would allow them to predict when a recession might begin. There are some variables, called leading economic indicators, that usually begin to decline before real GDP and employment decline. But those leading indicators are not completely reliable. For example, stock prices usually decline before a recession begins as investors anticipate the reduction in profits that occur during a recession. But although the largest one-day percentage decline in the S&P 500 stock index occurred on October 19, 1987, the next recession did not begin until nearly three years later. The late Nobel laureate Paul Samuelson of the Massachusetts Institute of Technology once joked that the stock market had predicted nine of the last five recessions.
Events That Trigger a Recession are Hard to Predict Perhaps most importantly, there are many different events that can trigger a recession and these triggering events are typically difficult to predict. For example, the answer to the Queen of England’s question about why economists failed to predict the financial crisis and recession of 2007-2009 is that very few economists recognized how vulnerable the U.S. financial system—and, therefore, the U.S. economy—was to a decline in housing prices.
Many economists believed that the doubling of housing prices between 2000 and 2006 was unsustainable. But few economists or policymakers realized that falling housing prices would lead many homeowners to default on their mortgages, particularly so-called subprime borrowers who had poor credit histories. Economists also didn’t realize these defaults would lead to falling prices of mortgage-backed and severe problems for financial firms that owned these securities. In a speech given in 2007, a few months before the Great Recession began, Federal Reserve Chair Ben Bernanke stated that: “We believe the effect of the troubles in the subprime sector on the broader housing market will likely be limited, and we do not expect significant spillovers from the subprime market to the rest of economy or to the financial system.” Bernanke’s opinion was shared by many other economists inside and outside the Fed. Because they didn’t fully understand that, given changes in the financial system over the previous 20 years, falling housing prices would lead to a financial crisis, most economists failed to predict the financial crisis that led to the Great Recession.
Similarly, most economists and policymakers underestimated the effects of Covid-19 when the disease first appeared in China at the end of 2019. In the past 20 years, the world has seen four similar viruses:
2002: Severe Acute Respiratory Syndrome (SARS)
2009: Swine flu
2012: Middle East Respiratory Syndrome (MERS)
For various reasons, none of these viruses reached the levels in the United States that required widespread quarantines or the closing of schools and other social distancing measures, although more than 12,000 people may have died of swine flu in the United States.
This experience led many economists, policymakers, firms, and investors to believe that the United States was unlikely to experience a significant economic disruption as a result of the coronavirus. From mid-December 2019 to mid-January 2020, none of the most widely followed forecasts of U.S. real GDP growth for the year 2020 indicated that a recession was likely. The real GDP forecasts from the Congressional Budget Office, the Federal Reserve’s Federal Open Market Committee, the Goldman Sachs investment bank, and 60 economists surveyed by the Wall Street Journal were all between 1.9 percent and 2.3 percent—comparable to the 2.3 percent increase in real GDP that the U.S. had experienced during 2019. The S&P 500 stock index reached a record high on February 19, 2020, despite China already having more than 50,000 cases of infection from the virus.
By mid-March, as cases of Covid-19 became common in the United States and most cities and states were announcing social distancing policies that included closing many non-essential businesses, the S&P 500 had declined by more than 30 percent and economists and policymakers all realized that the U.S. economy would be experiencing a substantial recession
That economists failed to predict the recessions of 2007-2009 and 2020 should probably not have been surprising. Economists Zidong An, João Tovar Jalles, and Prakash Loungani of the International Monetary Fund (IMF) studied how accurate economists were in forecasting recessions in 63 countries over the period from 1990 to 2014. They found that both economists in the private sector as well as the IMF’s own economists rarely succeeded in forecasting a recession before it had begun. On average during this period, real GDP declined by 2.8 percent during the first year of a recession. But in April of the year prior to the start of a recession, the average forecast from private sector economists and economists at the IMF was for an increase in real GDP of 3 percent. By October of the year prior to a recession, private economists had reduced their forecasts of real GDP for the following year on average to an increase of 2 percent and economists at the IMF had reduced their forecast to 2.5 percent but these forecasts were still well above the actual decline in real GDP of 2.8 percent.
In recent years, economists have devoted resources to forecasting how real GDP will change during the current quarter. This nowcasting, if accurate, can provide policymakers and economists information on how a recession is progressing while it is occurring. Nowcasting generally relies on identifying relationships between economic variables that have data available monthly or weekly and real GDP, which in the United States is calculated by the BEA quarterly. Because economists disagree on which data provide the most accurate forecasts of real GDP during the current quarter, their nowcasts can be strikingly different.
The following table shows seven nowcasts issued during mid-April 2020 of real GDP during the second quarter of 2020, during the recession caused by the coronavirus pandemic. The data are given as changes expressed at an annual rate, which means they should be interpreted as indicating what the change in real GDP would be if the rate at which GDP changed in that quarter were sustained for a year. (Note that the Weekly Economic Index (WEI) and the uncertainty based forecast were originally presented as the percentage change from the same quarter in the previous year and have been converted to an annual rate.) Six of the forecasts agree in predicting that real GDP would decline during the quarter at a very high rate of more than 25 percent. As a standard of comparison, before the second quarter of 2020, the largest two quarterly declines in real GDP since 1947 were the decline of 10.0 percent in the first quarter of 1958 and the decline of 8.4 percent in the fourth quarter of 2008. Even the more moderate decline predicted by the New York Fed’s Nowcast would be among the largest in the past 75 years.
Ultimately, the difficulty that macroeconomists encounter in forecasting changes in real GDP indicates the complexity of the macroeconomy. Economists have not yet succeeded in reducing this complexity to a statistical model that can reliably forecast changes in real GDP—particularly whether a recession is likely to occur.

Question: During the coronavirus pandemic, some people wondered why biologists seemed unable to answer many questions about the virus, including why children appeared rarely to become ill, why men were more likely than women to die from the virus, and why there was great uncertainty about whether some existing pharmaceuticals would be effective in treating the disease. Briefly discuss similarities and differences between the problem biologists faced in understanding the coronavirus and the problem economists face in predicting recessions.

On April 17th, Glenn Hubbard and Tony O’Brien continued their podcast series by spending just under 30 minutes discuss varied topics such as the Federal Reserve’s monetary response, record unemployment numbers, panic buying of toilet paper as compared to bank runs, as well as recent books they’ve been reading with increased downtime from the pandemic.
During the initial UNWRITTEN webinar from Pearson, Glenn Hubbard had a conversation with Jaylen Brown, a Pearson Campus Ambassador as well as a student at University of Central Florida -also Glenn’s undergrad alma mater!
Over the 30-minute broadcast, they discussed topics of relevance to all students – real world outlook on jobs, supply and demand, and the policies aimed at relief. Glenn talks of recovery shaped like a Nike swoosh with a sharp decline and a slightly longer climb back to normalcy. Check out the full episode now posted on YouTube!
On March 19th Glenn Hubbard sat down with the editorial team at Pearson to talk through some of the high-level economic issues involved in the coronavirus pandemic.
In this 10 minute podcast Glenn discusses the nature of the economic shock and what we should expect, based on historical shocks. We explore every day topics students are wondering about like what will the job market look like to the policy ideas of what could help stabilize the US economy.
Give your students the link and ask them any of the following discussion questions to get them thinking about the pandemic in an economic context:
1. Is this kind of economic supply shock a new concept or something that the U.S. has experienced before? Is there any precedent for whether this should be a short or drawn out recession? What factors will contribute to the length of the recession?
2. What economic policies would you prescribe for dealing with this crisis and why? Which policy would be the most beneficial for families given the current state of the economy? Which policies would be the most beneficial for businesses and long-term economic growth?
3. What current mandates as a result of the pandemic could translate into longer-term modifications to how we learn and work? Discuss the possible structural changes to the economy.
4. What are the trade-offs involved in controlling the pandemic? Assuming there will be a significant impact on the economy, what macroeconomic policies would you implement to soften the shock to allow people to more easily follow the guidelines to reduce the pandemic without suffering severe economic consequences? Will your policies help restart the economy once the pandemic has passed?
Instructors can access the answers to these questions by emailing Pearson at Christopher.email@example.com and stating your name, affiliation, school email address, course number.
