I could see this being more effective for a country than it is for municipalities within a country, simply because it's more difficult for them to leave once they're established. This is an extreme case, but I had a previous employer, a large multinational conglomerate, that moved my particular product team's home office twice in six years. Both moves were motivated by tax incentive. The cities would place conditions on how many jobs they had to "create" in order to get their perks, and they would "create" those jobs by relocating people from some other office in a town that was no longer giving them tax breaks.
