The surprising strength of economic sanctions deployed multilaterally against Russia this month has been exceeded only by the surprising strength of the heroic Ukrainian resistance to the invasion of their territory.  True, it is hard to imagine sanctions bringing the Russian economy to its knees faster than Russian troops are able to complete the hundred-mile advance to Kyiv from the border.  But sanctions have gone macroeconomic.  Ultimately, the Russian economy will suffer severely and lastingly.

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.

The “bicycle theory” used to be a metaphor for international trade policy.  Just as standing still on a bicycle is not an option — one has to keep moving forward or else the bike will fall over – so it was said that international trade negotiators must continue to engage in successive rounds of liberalization, or else the open global trading system would be pulled down by protectionist interests.  I don’t know if the theory was ever right.  (And, to be honest, I don’t entirely understand why forward movement keeps a bicycle from falling over.)  But if we had stood still on trade policy over the last three years we would be a lot better off than where we are now.

The US-China trade war heated up in the first week of August.  On August 1, Donald Trump abruptly announced plans to impose a 10 % tariff on the remaining $300 billion of imports from China that he had not already hit with earlier tariffs.   The Chinese authorities then allowed their currency, the renminbi (RMB), to fall in value below the highly visible line of 7.0 RMB/$.  The US Administration promptly reacted on August 5 by naming China a “currency manipulator” — the first time any country had been given that designation in 25 years.   Pundits declared a currency war, while investors responded by immediately sending stock markets down.

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.
