A generation of great international economists is passing from the scene.  Richard Cooper died on December 23. An American, he was teaching his classes at Harvard until the very end. Robert Mundell, passed away on April 4.  Originally Canadian, he was a winner of the Nobel Prize in economics.  And John Williamson, on April 11. Originally British, he had been the first scholar hired by the Peterson Institute for International Economics.

As Joni Mitchell sang, “you don’t know what you’ve got ‘til it’s gone.”   Classroom education was often deemed boring by students and obsolete by tech visionaries.  Then the coronavirus made it difficult or impossible to meet in person.  The result:  We yearn for the irreplaceable in-class experience.
Perhaps the same is true of international economic cooperation. It was never especially popular. The theory, first formulated in a 1969 paper by Richard Cooper, said that countries could agree to coordinated bargains that achieved better outcomes, relative to the “Nash non-cooperative equilibrium.”  But economists thought of plenty of reasons to be skeptical.  The multilateral institutions of cooperation such as the World Trade Organization, the International Monetary Fund, and the United Nations agencies, were downright unpopular among the public.  Many Americans regarded them as invading US sovereignty, while other countries viewed them as an invasion of their sovereignty by the US.

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.

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.

Newly announced GDP data give a preliminary estimate of 6.5 % in the 3rd quarter of 2018, relative to Q3 of 2017. The growth rate had been 6.7% previously.
