In a recent interview with the Financial Times, European Central Bank (ECB) executive board member Isabel Schnabel highlighted the need for economists to adopt a longer-term perspective when analyzing economic trends. She emphasized the necessity of recognizing that the world of tomorrow may be different from the world we are presently accustomed to.
Schnabel acknowledged that in 2020, the ECB's central bankers disregarded warnings from economic historian Charles Goodhart's book, titled 'The Great Demographic Reversal: Ageing Societies, Waning Inequality, and an Inflation Revival.' Goodhart's book argues that declining global populations will lead to an increase in inflation due to rising labor costs in the coming decades.
According to Schnabel, the Eurozone central bankers were too quick to dismiss Goodhart's concerns, largely due to being constrained by their own preconceived notions. She attributed the ECB's delayed response in raising interest rates as inflation rose after the pandemic to their excessive commitment to forward guidance.
"The problem was that we were so caught up in our thinking and this also influenced our policy reaction. We tied our hands too strongly by forward guidance," Schnabel explained. "This is the main reason why we were a bit late on both ending asset purchases and hiking interest rates."
Schnabel further noted that inflation had been declining and even turned negative in the latter half of 2020. After experiencing a prolonged period of low inflation, the prevailing concern was that inflation would remain low or potentially drop even further.
In light of these events, Schnabel's comments underscore the importance of taking a more comprehensive and forward-thinking approach in economic analysis. By recognizing that the future may hold unforeseen changes, economists can avoid being confined by their own assumptions and better navigate potential challenges.
The Importance of Flexibility in Central Banking
The recent economic uncertainties have highlighted the need for central bankers to adopt a more flexible approach. Isabel Schnabel, an economist at the European Central Bank (ECB), emphasized the significance of heeding Charles Goodhart's warnings and recognizing that economic conditions can change rapidly.
Schnabel stressed the value of listening to an experienced economic historian like Goodhart, who has witnessed numerous transformations in the world. "What I've learned," explained Schnabel, "is that we cannot assume that tomorrow's world will resemble today's. It can evolve swiftly." Moving forward, she believes that central bankers should prioritize maintaining flexibility.
Furthermore, Schnabel suggested that the ECB should reconsider its approach to issuing forward guidance. Instead of providing absolute statements, she argued that any future guidance should be contingent on economic data. Drawing on the Delphic oracle analogy, she insisted on the importance of basing decisions on facts rather than making binding commitments.
Schnabel also cautioned against relying too heavily on financial market movements when making policy decisions. She warned about the potential creation of feedback loops and referred to Paul Samuelson's "monkey in the mirror" analogy. According to Samuelson, central bankers who interpret market signals excessively are akin to a monkey believing its reflection provides new information.
In conclusion, Schnabel's insights emphasize the need for central bankers to embrace flexibility, reassess their approach to forward guidance, and exercise caution when interpreting financial market indicators. By recognizing the dynamic nature of the economy, central banks can adapt more effectively and make informed decisions based on concrete data.
