Michael Porter’s article in the March issue of HBR on choosing the United States makes the point that in choosing where to locate even high value-adding business activities, many companies don’t do a very thorough costs/benefits analysis. They tend to focus on the obvious and most easily measured benefits (lower wage costs, tax rates, etc.) and on the cost side struggle to even identify half of the items, especially those incurred in the future. The result is that many companies leave the U.S. when they probably shouldn’t.
