In the last decades the decision on the allocation of an assembly line complex has not followed the traditional pattern of polarization in only one region. This has been true all over the world. To many analysts, this new trend is a result of an increasing wave of fiscal war between subnational governments, leading to location decisions bounded by low rationality. This argument, however, has several limitations, as discussed in this article. I argue that although a fiscal war is part of this new productive/spatial arrangement, it is more a result than the cause of the process. Following this line of reasoning, location decisions carry on being rational, at least under current available information, even in cases labeled as extreme examples, such as the option made by Ford to locate in the state of Bahia its ambitious Amazon Project.
