The Unassuming Economist

From a F&D Article by M. Ayhan Kose, Prakash Loungani, and Marco E. Terrones:

By any measure, the ongoing global recession is the deepest and the most synchronized of the postwar period

The U.S. baseball season culminates in a championship called the World Series, reflecting a time when the United States was the world when it came to baseball. Likewise, in the 1960s, a recession in the United States could just as well have been called a global recession. The United States accounted for a large share of world output, and cyclical activity in much of the rest of the world was dependent on U.S. conditions.

What constitutes a global recession today? Although advanced economies like the United States used to account for roughly 75 percent of world output in the 1960s, their share is now only about 55 percent. As a result, the coincidence between business cycles in advanced economies and global business cycles can no longer be taken for granted. At the same time, however, the countries of the world are more integrated today through trade and financial flows than they were in the 1960s. This creates greater potential for spillover and contagion effects, increasing the odds of synchronous movements and a global business cycle.

Surprisingly, there is no commonly accepted definition of a global recession. Under the definition we propose here—a contraction in world real per capita gross domestic product (GDP) accompanied by a broad decline in various other measures of global economic activity—there have been four global recessions in the post–World War II period: 1975, 1982, 1991, and 2009. The current recession is easily the most severe of the four: output—depending on the measure—is projected to fall between four and six times as much as it did on average in the three other global recessions, and unemployment is likely to increase twice as much. The collapse in world trade this year dwarfs that in past global recessions. And no previous global recession has had so many countries in a state of recession simultaneously. Put simply, in baseball parlance, this global recession is out of the ballpark.

Let’s date

In deciding when a particular country is in recession, economists often use statistical procedures to date the peaks and troughs of a key indicator of economic activity, such as the country’s real GDP. Applying the same idea at the global level since 1960, we use annual data on world real per capita GDP, using purchasing-power-parity (PPP) weights, from 1960 to 2010 (see Box 1). The estimates for 2009–10 are based on the latest IMF growth forecasts (International Monetary Fund, 2009). A per capita measure is used to account for the vast differences in population growth rates across countries. Emerging and developing economies tend to have faster GDP growth than industrialized economies, but they also have higher population growth.

From a paper by Paolo Di Lorenzo and Eric Anthony Lacey“

“This paper provides an overview of issues related to fiscal consolidation drawing on the
literature; it distills some lessons from fiscal consolidation episodes using a new database covering
196 countries from 2000 to 2023. The paper discusses the motives, timing, design, and political
economy of fiscal consolidation, as well as its macroeconomic and social impacts. We find that
fiscal consolidation is often necessary and successful in restoring fiscal sustainability by stopping
debt accumulation, but less successful in lowering debt levels; moreover, it can also entail
significant costs and trade-offs in terms of growth, poverty, and inequality. Composition also
matters, as expenditure-based consolidations tend to be more successful than revenue-based
consolidations and less likely to cause a deterioration in poverty rates or inequality. However,
revenue gains usually play an important role starting in the second year of consolidation. Overall,
the paper suggests that successful fiscal consolidation requires careful consideration of the
economic context, the composition of adjustment, complementary economic policies, and
communication and credibility of the strategy. The best way to implement fiscal adjustment is to
establish a consolidation strategy in normal/non-crisis times} to ensure that governments do not
have to rely on abrupt, pro-cyclical adjustments that may exhaust all buffers in the aftermath of a
shock.

From a paper by Azzeddine Cheddad and Mohammed Mekidiche:

“This article analyzes the feasibility of inflation targeting (IT) in Algeria using data from Q1 2000 to Q4 2021. IT is widely used, although its efficacy in emerging areas, notably MENA, is disputed. Algerian monetary policy dynamics and the central bank’s response to inflation and production changes are examined using Taylor Rule and GMM. The Bank of Algeria appears to value interest rate smoothing above short-term economic instability. The central bank’s aggressive response to inflation goal deviations supports its price stability promise in an IT environment. The research shows a lower focus on production stability, possibly due to the oil-dependent economy and labor market rigidities. The study finds that Algeria’s monetary policy has IT aspects, but its efficacy depends on its economic setting and institutional architecture. To further comprehend Algeria’s macroeconomic stabilization efforts, future study should examine global economic circumstances, commodity price volatility, and monetary and fiscal policy. This study adds to the discussion on IT’s usefulness in emerging economies by highlighting the necessity to address economic conditions and institutional frameworks. IT may help stabilize prices in Algeria, but executing this monetary policy framework in a unique economic setting is difficult.”

From a paper by Peter Lihn, Jørgensen, and Kevin J. Lansing:

“We show that the fraction of non-reoptimizing firms that index prices to the inflation target, rather than lagged inflation, provides a simple measure of anchoring for short-run expected inflation in a New Keynesian model with full-information rational expectations. Higher values of the anchoring measure imply less sensitivity of rational inflation forecasts to movements in actual inflation. The approximate value of the model’s anchoring measure can be inferred from observable data generated by the model itself, as given by 1 minus the autocorrelation statistic for quarterly inflation. We show that a shift in the collective indexing behavior of firms allows the model to account for numerous features of evolving U.S. inflation behavior since 1960.”

Matthew A. Killingsworth, Daniel Kahneman, and Barbara Mellers explore the relationship between income and emotional well-being.

“Using dichotomous questions about the preceding day, [Kahneman and Deaton, Proc. Natl. Acad. Sci. U.S.A. 107, 16489–16493 (2010)] reported a flattening pattern: happiness increased steadily with log(income) up to a threshold and then plateaued. Using experience sampling with a continuous scale, [Killingsworth, Proc. Natl. Acad. Sci. U.S.A. 118, e2016976118 (2021)] reported a linear-log pattern in which average happiness rose consistently with log(income).”
