Climate Change Is a Source of Financial Risk
Glenn D. Rudebusch
The ongoing trend of climate change—including higher temperatures and more extreme weather—will result in economic and financial losses for many businesses, households, and governments. Moreover, the uncertainty about the severity and timing of these losses is a source of financial risk. Recently, the Federal Reserve joined other financial regulators to warn that such climate-related financial risk may threaten the safety and soundness of individual financial institutions and the stability of the overall financial system.

Can Government Spending Help to Escape Recessions?
Regis Barnichon, Davide Debortoli, and Christian Matthes
A key to designing fiscal policy is understanding how government purchases affect economic output overall. Research suggests that expanding government spending is not very effective at stimulating an economy in normal times. However, in deep downturns when monetary policy is constrained at the zero lower bound, public spending is more potent and can become an effective way to escape a recession.

The Asymmetric Costs of Misperceiving R-star
Andrea Ajello, Isabel Cairó, Vasco Cúrdia, and Albert Queralto
The natural rate of interest, or r-star, is used to evaluate whether monetary policy is restrictive or supportive of economic activity. However, this benchmark rate can only be estimated, and policymakers’ misperceptions of the level of the natural rate can carry substantial economic costs in terms of unemployment and inflation. A scenario using mistaken perceptions shows that the costs of overestimating the natural rate are greater than the cost of underestimating it if policy space is limited by the effective lower bound on the nominal federal funds rate.

2020 Lessons, 2021 Priorities
Mary C. Daly
What lessons should we take from a difficult year—and what should our priorities be for 2021? Overcoming the harsh and uneven economic impacts of COVID-19 and returning to full employment and sustainable 2% inflation will be the Federal Reserve’s chief concerns. But success will require us to have confidence in the power of our tools. The following is adapted from a presentation by the president and CEO of the Federal Reserve Bank of San Francisco to the Arizona State University Economic Forecast Luncheon on December 1.

Permanent and Transitory Effects of the 2008–09 Recession
Andrew Foerster and Lily M. Seitelman
Separating U.S. economic output into permanent and transitory components can help explain the effects of recessions and expansions. GDP growth shifted to a lower trend rate in 2000, indicating a slowdown long before the 2008–09 recession. GDP was substantially above trend before that recession; it then declined significantly and did not recover to its trend rate until 2017. The recession resulted in permanent losses to GDP. Without those permanent effects, GDP at the end of the latest expansion would have been about $380 billion or $1,460 per person higher.

Small Business Lending during COVID-19
Remy Beauregard, Jose A. Lopez, and Mark M. Spiegel
Small businesses and farms were hit hard by restrictions that limited their ability to pay operating costs during the COVID-19 crisis. Banks played an important supportive role, substantially expanding the loans available to these firms during the early months of the crisis. The growth in lending was associated with small business participation in the Paycheck Protection Program (PPP) and bank use of the PPP Liquidity Facility. Analyzing data for the first half of 2020 suggests that these programs were successful in supporting lending growth during the crisis, particularly among small banks.

Temporary Layoffs and Unemployment in the Pandemic
Erin Wolcott, Mitchell G. Ochse, Marianna Kudlyak, and Noah A. Kouchekinia
Temporary layoffs accounted for essentially the entire increase in unemployment to its historically high rate in April 2020. Although the rate has come down since its peak, unemployment remains well above pre-pandemic levels. There is little evidence that temporary layoffs are becoming permanent at a higher rate than in the past. However, the continuation of the health and economic crisis poses a risk that a growing share of unemployment will consist of people in persistent categories of joblessness, thereby slowing the overall recovery.

Sudden Stops and COVID-19: Lessons from Mexico’s History
Gianluca Benigno, Andrew Foerster, Christopher Otrok, and Alessandro Rebucci
The COVID-19 pandemic produced a sharp contraction in capital flows in emerging markets during the spring of 2020. Such contractions are known as “sudden stops” and historically have been associated with significant downturns in a country’s economic activity. Evidence from Mexico’s financial crisis history suggests that sudden stops tend to exhibit a common pattern: the crisis lasts one to two years before a rapid but partial recovery, followed by years of protracted stagnation.

Is the Federal Reserve Contributing to Economic Inequality?
Mary C. Daly
Not every American gets the same chance at life, liberty, and the pursuit of happiness. We have to acknowledge and confront this reality—as individuals, as institutions, and as a nation. The Fed can help create more inclusive economic success by finding full employment experientially. But achieving true equality will require commitment from all of us. The following reflects remarks delivered in a virtual presentation by the president and CEO of the Federal Reserve Bank of San Francisco to the University of California, Irvine, on October 13.

Assessing Recent Stock Market Valuation with Macro Data
Kevin J. Lansing
History suggests that elevated values of the cyclically adjusted price-earnings (CAPE) ratio may indicate an overvalued stock market. A valuation model that uses a small set of economic variables can help account for movements in the CAPE ratio over the past six decades. One of these variables is a macroeconomic uncertainty index. Comparing the model’s prediction for the second and third quarters of 2020 to the 2008–2009 period suggests that investors have reacted to macroeconomic uncertainty very differently during the COVID-19 outbreak than they did during the financial crisis.
