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.

iPhone Shows Why Global Imbalances Will Remain

Mercantilists are simply wrong.

The are mistaken in arguing for the "currency valve" policy option to address global ‘imbalances’. That’s because these mercantilists read or interpret trade as operating simplistically in an “aggregate” manner.

Yet as this study based on the iPhone’s business process shows, trade hasn’t been that simple.

Trade has been swiftly evolving in such a way that has deepened the role of specialization (division of labor) and national comparative advantages which has affected how “imbalances” are being shaped.

To add, current statistical aggregates tend to overlook many important data points which have been used for policy analysis. This makes many of these politically sensitive data unreliable.

The following conclusion from Yuqing Xing And Neal Detert on their paper “How iPhone Widens the US Trade Deficits with PRC” (all bold emphasis mine)

In this paper, we use the iPhone as a case to show that even high-tech products invented by American companies will not increase US exports, but to the contrary exacerbate US trade deficits.

Unprecedented globalization, well organized global production networks, and low transportation costs all contribute to rational firms such as Apple making business decisions that contributed directly to the US trade deficit reduction.

Global production networks and highly specialized production processes apparently reverse trade patterns: developing countries such as PRC export high-tech goods—like the iPhone—while industrialized countries such as the US import the hightech goods they themselves invented. High-tech products such as iPhones in this context do not help increase the US exports, but instead contribute to trade deficits.

In addition, conventional trade statistics greatly inflate bilateral trade deficits between a country used as export-platform by multinational firms and its destination countries. In the case of iPhone trade, China actually contributed only 3.8% of the United States’ US$1.9 billion trade deficit, the rest was simply a transfer from Japan, Korea, and Taipei,China.

If the US high-tech companies, such as the Apple, are willing to share their profits with low skilled American workers by keeping assembling jobs in the US, it would be more effective in reducing the US trade deficits than targeting the exchange rate policy of PRC.

University of Michigan Professor Mark J. Perry has a nice illustration of the composition or breakdown of revenues of the iPhone per location/geography as shown above.

He also notes that

“only about $6.54 (a little more than than 1%) of the full $600 retail price of an iPhone goes to China and more than 60% goes directly to Apple and other American companies (see chart above), according to a "teardown report" by iSuppli that was featured in a July New York Times article. It also doesn't mean that your purchase of an iPhone contributed very much to the U.S. trade deficit, even though that's what the government trade statistics tell us.”

So despite being assembled or "made in China" most of the profits still accrue to the US.

Bottom line: Globalization equals “imbalances”. That’s because of the fast evolving supply chain platforms or networks which has been determining the trading patterns globally.

Yet interventionist policies based on easy fixes are likely to backfire since they do not address the business and micro realities of trade.

Do iPhone Users Have More Sex Appeal?

Many interesting stuff from the web as this

iPhone users draw in more sexual partners than BlackBerry and Android users.

According to Professor Landsburg,

Data from 9,785 users of the dating site OKCupid reveal that iPhone users have 50% to 100% more sex partners than Android users, at every age.

This graph combines men and women, but the same pattern holds for each gender separately.

Correlation isn’t causation, i.e. doesn’t mean that you buy and use an iPhone you automatically get a surge of admirers from the opposite sex, but what gives?

iPhone Global Supply Chain, The Power of the Market Through The Division of Labor

The New York Times talks about supply chain structure of the iPhone and its costs,

``According to the latest teardown report compiled by iSuppli, a market research firm in El Segundo, Calif., the bulk of what Apple pays for the iPhone 4’s parts goes to its chip suppliers, like Samsung and Broadcom, which supply crucial components, like processors and the device’s flash-memory chip.

``In the iPhone 4, more than a dozen integrated circuit chips account for about two-thirds of the cost of producing a single device, according to iSuppli.

``Apple, for instance, pays Samsung about $27 for flash memory and $10.75 to make its (Apple-designed) applications processor; and a German chip maker called Infineon gets $14.05 a phone for chips that send and receive phone calls and data. Most of the electronics cost much less. The gyroscope, new to the iPhone 4, was made by STMicroelectronics, based in Geneva, and added $2.60 to the cost.

``The total bill of materials on a $600 iPhone — the supplies that go into final assembly — is $187.51, according to iSuppli.

However, when I reached the portion when the article mentioned “The world of contract manufacturers is invisible to consumers”, it dawned upon me that the author was dealing with wonders of the division of labor in passing.

Yes indeed, the iPhone is a product of a global division of labor!

And a great illustration of the magic of the division of labor was written by Leonard Read in his classic “I, the Pencil”, where he shows how people from diverse places and distinct cultures work spontaneously and invisibly in harmony to produce what seems like a simple product- the pencil- which you and I use.

The illustrious Milton Friedman does a great job discussing Mr. Read’s classic, below…
