iPod, product of world economy
Assembly, Components Globally Outsourced
From NYT NEWS SERVICE
New York: Who makes the Apple iPod? Here’s a hint: It is not Apple. The company outsources the entire manufacture of the device to a number of Asian enterprises, among them Asustek, Inventec Appliances and Foxconn.
But this list of companies isn’t a satisfactory answer either: They only do final assembly. What about the 451 parts that go into the iPod? Where are they made and by whom? Three researchers at the University of California, Irvine—Greg Linden, Kenneth L Kraemer and Jason Dedrick—applied some investigative cost accounting to this question, using a report from Portelligent Inc that examined all the parts that went into the iPod.
Their study, sponsored by the Sloan Foundation, offers a fascinating illustration of the complexity of the global economy, and how difficult it is to understand that complexity by using only conventional trade statistics. The retail value of the 30-gigabyte video iPod that the authors examined was $299. The most expensive component in it was the hard drive, which was manufactured by Toshiba and costs about $73.
The next most costly components were the display module (about $20), the video/multimedia processor chip ($8) and the controller chip ($5). They estimated that the final assembly, done in China, cost only about $4 a unit.
One approach to tracing supply chain geography might be to attribute the cost of each component to the country of origin of its maker. So $73 of the cost of the iPod would be attributed to Japan since Toshiba is a Japanese company, and the $13 cost of the two chips would be attributed to the US, since the suppliers, Broadcom and PortalPlayer, are American companies, and so on.
Toshiba may be a Japanese company, but it makes most of its hard drives in the Philippines and China. So perhaps we should also allocate part of the cost of that hard drive to one of those countries.The same problem arises regarding the Broadcom chips, with most of them made in Taiwan. So how can one distribute the costs of the iPod components across the countries where they are manufactured in a meaningful way?
To answer this question, let us look at the production process as a sequence of steps, each possibly performed by a different company operating in a different country. At each step, inputs like computer chips and a bare circuit Assembly, Most Components Globally Outsourced board are converted into outputs like an assembled circuit board.
The difference between the cost of the inputs and the value of the outputs is the “value added” at that step, which can then be attributed to the country where that value was added. The profit margin on generic parts like nuts and bolts is very low, since these items are produced in intensely competitive industries and can be manufactured anywhere.
Hence, they add little to the final value of the iPod. More specialized parts, like the hard drives and controller chips, have much higher value added.
In this way, the researchers examined the major components of the iPod and tried to calculate the value added at different stages of the production process and then assigned that value added to the country where the value was created.
Ultimately, there is no simple answer to who makes the iPod or where it is made. The iPod, like many other products, is made in several countries by dozens of companies, with each stage of production contributing a different amount to the final value.
Those clever folks at Apple figured out how to combine 451 generic parts into a valuable product. They may not make iPods, but they created it. In the end, that’s what really matters.
