Research

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.
