Imagine what Baruch found in his daily Abnormal Returns troll last thrusday, Bento! It seems 2 academic dudes, one Yuqing Xing and another Neal Detert at the Asian Development Bank Institute in Japan, took a look at the iPhone and the US-Chinese trade deficit, and realised that high tech products such as the iPhone, which are merely assembled in China, distorted the picture. Very little of the value of the iPhone comes from, or remains in China, yet the full value of the iPhone is counted as a Chinese export for the purposes of deficit calculation. The official numbers are wrong, therefore, and the “real” deficit is much lower.
All well and good, and jolly interesting too. So much so that it was picked up by the WSJ, Paul Kedrosky, and of course, Tadas at AR.
Baruch certainly found the article interesting, as these were thoughts very similar to those he set down over one year ago in a blogpost here called What’s an export? Seriously. In it, after examining the supply chain of the iPhone* in some detail, he concluded that high tech products which are merely assembled in China distorted the picture. Very little of the value of the iPhone comes from, or remains in China, yet the full value of the iPhone is counted as a Chinese export for the purposes of deficit calculation. He wrote
Presumably to work out the real trade balance in terms of where trade flows, or where the wealth generated by iPhones goes, classifiying it as a {Chinese} export for the purposes of assessing a trade balance is misleading . . . Where there are totally integrated global supply chains, I suspect that the definitions of “import” and “export” begin to lose meaning.
Baruch was confused: why did economists and politicians harp on about the trade deficits like this when it assessing the true value of the deficit was so obviously problematic? The post ended with a plea:
If there are any professional economists left reading UB, please help.
“Help” in this case, did not mean “purloin my idea and publish it in your own name for the glorification of your career without so much as citing poor old Baruch.”
What do you think Bento? Can I sue?
*happily, Xing and Detert also make a hash of the foodchain of the iPhone. Toshiba does NOT make the touchscreen and display module of the iPhone, though may be implicated in the NAND memory; touch module is left to an obscure-ish Taiwanese company called TPK, the screen could come from a whole passel of suppliers, but probably not Tosh; the apps processor is only “fabbed” by Samsung but is a design owned by Apple, Infineon does not make the “camera module”, though does make the baseband and some other stuff. Etc etc.
