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.
