Abstract:
Bernanke and Blanchard (2023) use a simple dynamic New Keynesian model of wage-price determination to explain the sharp acceleration in U.S. inflation during 2021-2023. They claim their model closely tracks the pandemic-era inflation and they confidently conclude that “… we don’t think that the recent experience justifies throwing out existing models of wage-price dynamics.” This paper argues that this confidence is misplaced. The Bernanke and Blanchard is another failed attempt to salvage establishment macroeconomics after the massive onslaught of adverse inflationary circumstances with which it could evidently not contend. It misrepresents American economic reality, hides distributional issues from view, de-politicizes (monetary and fiscal) policy-making, and sets monetary policymakers up to deliver significantly more monetary tightening than can be justified on the basis of more realistic model analyses.

Abstract:
This paper analyzes claims that the Federal Reserve is principally responsible for the decline of inflation in the U.S. We compare several different quantitative approaches. These show that at most the Fed could plausibly claim credit for somewhere between twenty and forty percent of the decline. The paper then examines claims by central bankers and their supporters that a steadfast Fed commitment to keeping inflationary expectations anchored played a key role in the process. The paper shows that it did not. The Fed’s own surveys show that low-income Americans did not believe assurances from the Fed or anyone else that inflation was anchored. Instead, what does explain much of the decline is the simple fact that most workers nowadays cannot protect themselves by bargaining for higher wages. The paper then takes up the obvious question of why steep rises in interest rates have not so far led to big rises in unemployment. We show that recent arguments by Benigno and Eggertson that shifts in vacancy rates can explain this are inconsistent with the evidence. The biggest factor in accounting for the strength in the economy is the continuing importance of the wealth effect in sustaining consumption by the affluent. This arises, as we have emphasized in several papers, from the Fed’s quantitative easing policies. Absent sharp declines in wealth, the continuing importance of this factor is likely to feed service sector inflation in particular.

3. Betting on Black Gold: Oil Speculation and U.S. Inflation (2020-2022)

Abstract:
Sharp increases in systemically important crude oil prices have been a major cause of the recent surge in the inflation rate in the U.S. This paper investigates the extent to which the increase in oil prices can be attributed to excessive speculation in the oil futures market. Our analysis suggests that excessive speculation in the crude oil market has been responsible for 24%-48% of the increase in the WTI crude oil price during October 2020-June 2022. These estimates translate into an oil price increase of around $18-$36 per barrel and an increase in the U.S. PCE inflation rate by circa 0.75 to 1.5 percentage points during the same period. We complement the analysis with an empirical investigation of the crude oil market which shows that (speculative) long non-commercial open-interest positions in oil futures have increased considerably relative to short non-commercial positions. We further find that higher futures prices for crude oil ‘Granger-cause’ oil spot prices, the futures prices of corn and soybeans and the fertilizer price. These econometric results show that oil speculators have to be held accountable for not just raising oil prices, but also driving up food commodity prices. We finally discuss measures to clamp down on excessive speculation in oil in order to eliminate its systemically adverse consequences for the U.S. economy.

4. The Art of Paradigm Maintenance: How the ‘Science of Monetary Policy’ tries to deal with the inflation of 2021-2023

Abstract:
The macroeconomic models used by major institutions including the Federal Reserve and the International Monetary Fund (IMF) failed to predict the inflation surge during 2021-2023. The output gap, the unemployment gap, the New Keynesian Phillips curve and inflation expectations did not give timely and relevant signals. The re-emergence of inflation thus threw the ‘science of monetary policy’ off the rails. Faced with the choice between changing their paradigm and proving that there is no need to do so, the ‘scientists of monetary policy’ got busy on the proof. As a result, a number of ad-hoc epicycles have been added to the New Keynesian analytical core—with the help of which one can claim to be able to explain the sudden acceleration of inflation post-factum. This paper critically reviews the theoretical and empirical merits of three recent tweaks to the New Keynesian core: using the vacancy ratio as the appropriate measure of real economic activity; hammering on the considerable risk of an imminent wage-price spiral; and the resurrection of the non-linear Phillips curve. The paper concludes by drawing out sobering lessons concerning the art of paradigm maintenance as practiced by the ‘scientists of monetary policy’.

5. Inflation in the Time of Corona and War

Abstract:
Reliance on established macroeconomic thinking is not of much use in trying to understand what to do in response to the constellation of forces driving up inflation in these times of COVID-19 and war. This paper attempts to reduce the heat and turn up the light in the debate on the return of high inflation and looming stagflation—by providing evidence-based answers to the main (policy) questions concerning the return of high inflation: is the increased inflation due to (global) supply and/or demand factors? Is the inflation in the US exceptional or are other OECD and emerging economies experiencing similar inflationary pressures? Is the increase in inflation permanent or transitory? Can the Fed safely bring down inflation? Is fiscal policy the underlying cause of inflation? Are there alternative, less socially costly, ways to bring inflation down? And what will happen to inflation in the longer run, when the US and other economies will face the impacts of global warming?

Abstract:
Reliance on established macroeconomic thinking is not of much use in trying to understand what to do in response to the constellation of forces driving up inflation and slowing down growth in these times of COVID-19 and war. This paper attempts to reduce the heat and turn up the light in the debate on the return of high inflation and looming stagflation—by providing evidence-based answers to key (policy) questions concerning the return of high inflation: How close are the parallels between the current conjuncture and the 1970s? What are the differences? Does what is currently happening already amount to stagflation? Can central bankers engineer a ‘soft landing’ of their economies or are we already poised for a deep (global) recession? What are the likely spill- over effects of monetary tightening in the US on the emerging economies? What, if anything, can we learn from the monetary and fiscal policy experiences and policy mistakes of the 1970s? And, finally, are there alternative, less socially costly, ways to bring inflation down?
