Fiscal competition and economic freedom
This is the question addressed by Jason Fichtner and Katelyn Christ in their working paper for the Mercatus Center.

It is important for Congress to focus on implementing stable low marginal tax rates that do not discourage working, saving, or investing and provide taxpayers with some degree of certainty to make growth promoting economic decisions.
