iPhone Shows How Trade Statistics are Flawed

I earlier pointed out that statistics hardly captures the realities of the swiftly shifting trade dynamics brought about by globalization as exemplified by the iPhone.

Here’s an update. From the Wall Street Journal Blog

The iPhone provides a good example of the problems with the way trade is currently calculated. The Apple device features hardware from all over the world, but because it’s manufactured in China that country gets credit for the entire wholesale export cost. According to research from Kenneth L. Kraemer of the University of California, Irvine, Greg Linden of University of California, Berkeley, and Jason Dedrick of Syracuse University, each iPhone sold in the U.S. adds $229 to the U.S.-China deficit. Based on 2011 cellphone activations from AT&T, Verizon and Sprint, Apple sold around 30 million iPhones in the U.S. last year — accounting for about $6.83 billion of the U.S.’s $282 billion 2011 trade deficit with China.

But the researchers note that such estimates overstate China’s contribution. Though the iPhone is assembled in China, most of its component parts come from elsewhere. Separate research by Yuqing Xing and Neal Detert for the Asian Development Bank Institute noted that for the iPhone 3G just about 3.6% of the wholesale price came from China, the rest could be attributed to inputs from companies in Japan, Germany, Korea and even the U.S. (Read more about that study here.)

The iPhone is just one example. This same phenomenon is happening all over the world in products ranging from cars to children’s toys. In an attempt to better gauge which countries are benefiting or losing the most through trade, the Organization for Economic Co-operation and Development and the World Trade Organization announced that they will be working on a project that identifies where value-added flows are coming from.

More confirmatory evidence where human action cannot be quantified.

This only validates Professor Ludwig von Mises who wrote

The impracticability of measurement is not due to the lack of technical methods for the establishment of measure. It is due to the absence of constant relations. If it were only caused by technical insufficiency, at least an approximate estimation would be possible in some cases. But the main fact is that there are no constant relations. Economics is not, as ignorant positivists repeat again and again, backward because it is not "quantitative." It is not quantitative and does not measure because there are no constants. Statistical figures referring to economic events are historical data. They tell us what happened in a nonrepeatable historical case. Physical events can be interpreted on the ground of our knowledge concerning constant relations established by experiments. Historical events are not open to such an interpretation.

To add, the deepening of the information age will further complicate trade dynamics as commerce will become increasingly more about niches and specialization or decentralization.

Lastly, the other implication is that using flawed trade statistics to argue for political actions (such as protectionism) is like shooting oneself in the foot.
