Is there really much about the Laffer curve to study? I mean, I get the whole increased tax rate can lead to decreased taxes, but as far as I know there is no theoretical or empirical model for such a curve, just a basic idea that the relationship can exist. This is why Rothbard criticized it, because he said there is no way to tell what shape this curve is (aside from the fact that he said the government shouldn't be trying to maximize tax receipts).
