The World Bank on May 19, as it does every six years, released the results of the most recent International Comparison Program (ICP), which measures price levels and GDPs across 176 countries.  The new results are striking.  It is surprising that they have received almost no attention so far, perhaps overshadowed by all things coronavirus.

For the first time, the ICP shows China’s total real income as slightly larger than the US.  It reports that China’s GDP was $19,617 billion in 2017, in Purchasing Power Parity (PPP) terms, while the United States’ GDP stood at $19,519 billion.

Once again, new economic readings from the World Bank's International Comparison Program have fed into the long-going debate over whether China is surpassing the United States as an economic and financial power. And once again, the answer to that question is a qualified "no."

This interview by Associated Press is the basis of quotes in a story today: “Risk of reopening US economy too fast: A W-shaped recovery.

In the GFC of 2008/2009 the world fell into recession for a while (one year), but the emerging world almost didn’t suffer: they kept growing, mostly thanks to commodity prices. Now, the story looks pretty different: even emerging countries will experience negative growth in 2020… It seems to be a truly global crisis. Should this worry us more?

“Those who cannot remember the past are condemned to repeat it,” George Santayana famously quipped in 1905. It is a phrase that has been repeated for over a century, but rarely heeded. As Covid-19 decimates the global economy, our understanding of history could be the difference between a V- or U-shaped recession and a W-shaped one, in which incipient recovery is followed by successive relapses.

As recently as March, V-shaped recoveries in individual economies seemed plausible. Once infections and deaths had peaked and begun to decline, the logic went, people would eagerly return to work. The economic activity might even get an extra boost, as consumers released pent-up demand.

“Those who do not study history are condemned to repeat it.”  And the rest of us are condemned to repeat George Santayana.

Will the Coronavirus Recession of 2020 be V-shaped?  Or U-shaped?  If we fail to heed the lessons of history it is likely to be W-shaped, with incipient recovery followed by successive relapses into sickness and recession.

As has been widely noted, we would have been better prepared to cope with the Covid-19 pandemic in the first place if everyone had paid more attention to the past history of epidemics. Be that as it may, the world is now deep into the pandemic and its economic consequences, the most severe such events since the interwar period, 1918-1939.  As decision-makers in every country contemplate their next steps, they would do well to ponder the precedents of that interwar period.

Events like the COVID-19 pandemic of 2020, the US housing crash of 2007-09, and the terrorist attack of September 11, 2001, are called “black swans”: in each case, few people were able to predict them reliably, at least not with precision.  But they were known unknowns, not unknown unknowns.  That is, in each case, knowledgeable analysts were fully aware that such a thing could happen, even that it was likely to happen eventually.  They could not predict that the event would happen with high probability in any given year.  But the consequences of each of these events were severe, and predictably so.  Thus, policymakers should have listened to the warnings and should have taken steps in advance. They could have helped avert or mitigate disaster if they had done so.

Contrary to what US President Donald Trump would like to believe, a pandemic like COVID-19 was predicted as recently as last year. After being caught off guard by yet another catastrophe, one wonders when political leaders, markets, and average citizens will start to take risk seriously.

At the start of the year, the economic mood was tending toward the optimistic.  True, growth had slowed a bit in 2019. US GDP grew 2.3 % in 2019, down from 2.9 % in 2018.  World growth was weak in 2019 as well: 2.9% according to IMF estimates, down from 3.6 % the year before.  Still, there had been no recession.  And forecasts as recently as January called for world growth to rebound in 2020.

At the start of this year, things seemed to be looking up for the global economy. True, growth had slowed a bit in 2019: from 2.9% to 2.3% in the United States, and from 3.6% to 2.9% globally. Still, there had been no recession, and as recently as January, the International Monetary Fund projected a global growth rebound in 2020. The new coronavirus, COVID-19, has changed all of that.
