Abstract:
The speed of both the rise and fall of US inflation in 2021–23 took many economists by surprise. This paper shows that the rise of COVID era inflation reflects three independent shocks: a plethora of pandemic-related shifts in demand patterns and supply disruptions; the largest commodity price surge in 40 years caused by the Ukraine war; and strong monetary and fiscal responses to the pandemic, which kept labor markets tight. This paper documents the transmission of these shocks through the main components of private consumption: durable goods, nondurable goods, and services. The rapid fall of inflation reflects the credibility of the Federal Reserve’s commitment to low inflation, something that was not apparent during the inflationary shocks of the 1970s but that was important during the Korean War inflation of 1950–51. Another similarity with the Korean War episode is the temporary surge in demand for durable goods.

2. The Role of Long Histories of “Lived Experience” in the COVID-Era Inflationary Surge

Abstract:
A rough consensus has evolved around the causes of the COVID-era inflationary spike: the disruption in supply chains; the shift in demand from services to goods; the surge in commodity prices that followed Russia’s invasion of Ukraine; and the pandemic fiscal stimulus programs. In this paper, we highlight an additional factor influencing the incidence of pandemic inflation across countries—their long histories of “lived experience” with inflation. We show that more than half of the variation in inflation across countries during the 2020–23 period can be explained by their earlier levels of inflation. Even controlling for inflation in the 2016–19 period, countries with higher inflation in the 2000–2015 period had higher COVID-era inflation, and the effect of long-lagged inflation is both economically and statistically significant. These long histories of lived experience dominated other policy measures to control inflation, including inflation targets and central bank independence. The influence of long-lagged inflation history appears to be greatest during periods of heightened volatility; it was less important in explaining the cross-country pattern of inflation during the more tranquil period immediately preceding the pandemic.

3. The inflation surge in Europe

Author:

Publication Date:

Content Type:
Policy Brief
Institution:
Peterson Institute for International Economics (PIIE)
Abstract:
For most of the decade before the COVID-19 pandemic, undershooting rather than overshooting had been the main inflation problem of the European Central Bank (ECB). During 2020, consumer prices in the euro area were falling; by the end of that year, average inflation since the introduction of the euro two decades earlier stood at only 1.6 percent per year. Things began to snowball in 2021. The 12-month inflation rate steadily accelerated. It reached double digits in the final quarter of 2022—more than twice the level it had ever reached since the euro’s introduction in 1999. Four striking features emerge from a review of the unexpected surge in European inflation since 2021: (1) The ECB’s monetary policy response lagged behind that of the US Federal Reserve, reflecting the more gradual evolution of inflation in the euro area and its distinct pattern of causes; (2) the range of inflation rates across different euro area countries has been unprecedented. This largely reflects the differential impact of war-related energy shocks (especially for natural gas piped from Russia) as well as the differential fiscal response by national governments partially insulating consumers from these shocks; (3) not all households were net losers from the inflation, with some benefiting from the fact that inflation reduced the real value of their indebtedness; and (4) the speed with which inflation was returning toward target during 2023 prompted concerns that the ECB’s monetary tightening might have been pushed too far, prolonging the output slowdown.

4. The influence of gasoline and food prices on consumer expectations and attitudes in the COVID era

Author:

Content Type:
Policy Brief
Institution:
Peterson Institute for International Economics (PIIE)
Abstract:
Food and gasoline prices are extremely salient to consumers, who regularly purchase these goods, and these prices are highly visible. The shared experience of purchasing food and gasoline makes it no surprise that those prices have been blamed for the relatively dismal consumer views of the economy in 2023 amid strong economic indicators, including slowing inflation, low unemployment, and robust growth. At the same time, consumer inflation expectations have eased during this past year. This Policy Brief investigates the role food and gasoline prices play in influencing consumer inflation expectations and economic sentiment, as measured on the University of Michigan Surveys of Consumers, and focuses on the COVID inflationary episode. The author finds that, although consumer sentiment now appears to be more sensitive to inflation than prior to the pandemic, inflation expectations do not. Even though inflation has waned, consumers still spontaneously comment on the negative impact of high prices on their lives. That said, these persistently negative perceptions about inflation have not translated into persistently high inflation expectations.

5. Lessons from China's fiscal policy during the COVID-19 pandemic

Author:

Publication Date:

Content Type:
Working Paper
Institution:
Peterson Institute for International Economics (PIIE)
Abstract:
Expansionary fiscal policy helped China's economy grow in 2020, a year in which most economies contracted because of the COVID-19 pandemic. Amid a broader pivot to policy and regulatory tightening, fiscal support was withdrawn in 2021. In 2022, government budget turned expansionary to ensure economic stability ahead of the Communist Party Congress, but the execution fell short and fiscal policy ended up being weaker than planned. A recurrent problem during the pandemic, however, was that local governments did not fully spend their budgets. Aside from the sharp drop in local governments' land sale revenue in 2022, which dragged down their spending, it was also caused by local governments' failure to fully utilize their special bond quotas approved by the central government for capital investment. China's fiscal policy during the COVID-19 pandemic highlights four issues with implications for fiscal policy making. First, the government needs to avoid projecting unrealistically high land sale revenue in its budgets. Second, it needs to reconsider its problematic use of local-government special bond as a major fiscal stimulus instrument. Third, it needs to make sure its deficit, growth, and inflation targets are consistent. Last, Beijing needs to be more tolerant of higher fiscal deficits, at a minimum ensuring that overall fiscal spending grows at least as rapidly as nominal output.

6. The Trinity of COVID Era Inflation in G7 Economies

Author:

Content Type:
Working Paper
Institution:
Peterson Institute for International Economics (PIIE)
Abstract:
COVID era inflation was driven by a unique combination of three shocks: First, a plethora of pandemic-related shifts in demand patterns and disruptions to supply caused prices of consumer durable goods to skyrocket. Second, the Ukraine war caused the largest global commodity price surge in 40 years, which mainly affected prices of nondurable goods such as food and gasoline. Third, strong monetary and fiscal responses to the pandemic recession caused labor markets to tighten, pushing up prices of services. This paper estimates models of the components of consumer prices in each G7 economy in order to document the transmission of these shocks. The first two shocks had run their course by 2023, enabling overall inflation to decline sharply from its 2022 peak. But labor markets remained at least moderately tight in most G7 economies in 2024, and services inflation remained noticeably higher than its pre-pandemic level.

7. Egypt’s 2023–24 Economic Crisis: Will This Time Be Different?

Policy Brief
Institution:

Abstract:
Egypt narrowly averted a full-blown economic crisis in early 2024 when the International Monetary Fund (IMF) and others gave Egypt a financial lifeline to curb its losses of foreign exchange reserves. This Policy Brief traces the origins and developments of the current crisis, and the country's history of repeated balance of payments crises. The 2023-24 crisis is one of eight such events in Egypt since 1952, driven by governance and policy deficiencies. The COVID-19 pandemic and the war in Ukraine have exacerbated Egypt's problems. Egypt's strategic importance in the Middle East, underscored by the Gaza conflict, has ensured continued international financial support, allowing Egypt to bet on its "too strategic to fail" position and avoid reforms. Entrenched military dominance and cronyism have obstructed necessary economic reforms. The authors conclude that Egypt needs to address these challenges and undertake major reforms to break free from its recurring cycle of crises and stop relying on international bailouts.

8. Did Supply Chains Deliver Pandemic-Era Inflation?

Author:
Phil Levy
Publication Date:

Content Type:
Policy Brief
Institution:
Peterson Institute for International Economics (PIIE)
Abstract:
This Policy Brief argues that supply chain breakdowns were not a principal cause of pandemic-era inflation. Levy focuses on US trade in containerized goods and shows that, within months of the pandemic’s onset, the quantities of goods delivered in fact increased significantly. The sharp increases in inflation and shipping prices and the accompanying delays and empty shelves in the presence of significantly increased quantities suggest, instead, a large positive demand shock. Goods consumption levels rose sharply and remained elevated into 2023 and beyond, even as shipping delays and price hikes dissipated. The author concludes that, while it may be worthwhile to make supply chains more efficient and aim for increased elasticity of supply, the goal of avoiding inflation and shortages is likely better met through improved demand management.

9. How did Korea’s fiscal accounts fare during the COVID-19 pandemic?

Author:

Abstract:
South Korea undertook a number of important fiscal steps in 2020-21 to fight the COVID-19 pandemic. Key policies it adopted were common to most advanced economies, including transfers to support households, firms, and workers and increased resources for public health measures such as testing, tracing, quarantines, and vaccine rollouts. In terms of the increase in overall pandemic spending, Korea did as much as the typical advanced economy. Yet its fiscal deficit was lower than those of other advanced economies for reasons unrelated to the magnitude of its fiscal response. The authors find that Korea’s fiscal revenues rose more strongly than in most other advanced economies despite few discretionary changes to tax rates, reflecting strong revenues from asset-based taxes in an environment of rising asset prices. This serendipitous surge in revenues offset much of Korea’s pandemic-related increases in expenditures, keeping its fiscal deficit low. Korea’s GDP rose more strongly in 2020-21 than GDP in most other advanced economies, reflecting strong foreign demand for Korean exports and a better public health response, which minimized COVID mortality and necessitated fewer restrictions on mobility.

10. Rare macroeconomic disasters and lost decades in Latin America: The COVID-19 experience in a historical context

Abstract:
COVID-19 led to the single largest year-over-year decline in Latin America’s GDP per capita in more than 100 years. Although the region has endured several macroeconomic shocks before, mostly related to financial dislocations, none has been so deep and synchronized. The authors' analysis of the COVID-19 experience for the region and eight economies with available historical data reveals the extent of the damage. Through 2020, four economies suffered “rare disasters” (cumulative contractions by 10 percent or more): Argentina, Mexico, Peru, and Venezuela. Tragically, Venezuela’s macroeconomic collapse matches the largest contraction registered by any country in modern history. In addition, Argentina, Brazil, Mexico, and Venezuela, together with the Latin America regional aggregate, are undergoing “lost decades” (prolonged periods of stagnation), which are unlikely to end soon. While Brazil, Chile, Colombia, and Uruguay did relatively better with COVID-19, they still suffered significant recessions, and their economic performance has lost steam compared with prior decades. Overall, COVID-19 will cast a long shadow in Latin America even as economic growth rebounds. The shock also offers opportunities for a reset, with the appropriate set of macroeconomic policies, advances on microeconomic reforms, and the strengthening of institutions. Whether this set of policies will materialize in the midst of challenging political contexts remains an open question.
