China growth as a case study for global innumeracy; another reason to ignore media news stories….


Economists are boring, but admitting to finding Hank Paulson refreshing is beyond admitting boredom; but I confess the saturation of the airwaves with interviews of his views on China while promoting his new book (Dealing with China: An Insider Unmasks the New Economic Superpower by Henry M. Paulson) was a personal pleasure.  We have been pummeled by the media with commentary about how the China economy is in trouble as standard GDP year on year growth approaches 7%.  Rubbish.

Paulson gets it right on the fundamentals; disaggregation of the forces and drivers is the best methodology for looking at China.  What I found interesting (over and over again) was his refusal to deal with the macro number.  Again he is correct. Financial innumeracy amongst politicians is endemic.

As the basis has expanded, normal (untransformed) year on year growth will always rescale, but those in the media and politics cannot grasp this concept. Those of us who are boring just have to keep reminding them how to pronounce ‘logarithmic’. This is about finance and economics and budgets and all manner of detail which should be their expertise, but is at the end of the day a demonstration of their lack of suitability (IMHOP) for the job.   It is not the law of large numbers, is it just basic ignorance.

Why China's economy is slowing  Mar 11th 2015  by S.R. | SHANGHAI


The law of large numbers (financial, rather than statistical) applies to nations as well as to companies: the bigger an economy gets, the harder it is to keep growing at a fast clip. Growth of 7% this year for China would generate more additional output than a 14% pace did in 2007.

The simple arithmetic of China’s growth slowdown     Danny Quah | February 18, 2015


The conclusion? China in 2015 is a very different economy from even just 10 years ago. It has changed far more than the world at large has in this time. A 7 percent growth rate is obviously lower than an 8 percent one. So, whatever good comes from a 7 percent growth rate, at the margin a growth rate a little higher will be even better. But, quantifying the changes that have taken place in the global economy, a 7 percent growth rate for China today means something even more positive than did a 12 percent growth rate 10 years ago.
