iPhone Development Reduces GDP Until The Final Product Is Released

From supply and demand (in that order) blog,"The iPhone5 and Consumer Spending" by Casey B. Mulligan:

the development of Apple products reduces consumption before the release, because the people working on the coming products are not available to produce consumer goods during that time.

Much of the development work on the iPhone 5 did not, before its release, count as investment or G.D.P. (G.D.P. is the sum of public and private consumption and public and private investment). The national accounts treat research and development activities as intermediate inputs, which means that they are subtracted from revenue for the purpose of determining a corporation’s contribution to national production.

This same is true for, say, Apple’s legal expenses in developing patents (many of which are discussed on the Mactech Web site) and license terms for their new product.

These development activities appear as G.D.P. only when the product is completed and sold. If the product is not valuable, it will not sell and will not count for much, although national consumption could still rise if upon project completion the developers move out of development and into the production of consumer goods.
