For a great discussion of the Laffer curve and supply-side economics, check out the following YouTube video hosted by Cato’s Dan Mitchell:

Dan is an old friend of mine. He’s a first-rate economist and has been one of the mainstays of the supply-side movement down through the years.

Dan does a very good job walking through the linkage between changing tax rates and their impact on economic behavior, growth, and tax-revenue collections. He states plainly that upper-end tax rates and investment tax rates are where the real incentive effects are the greatest (for more on this particular subject, check out Art Laffer’s recent WSJ op-ed). Moreover, Mitchell does not make the false claim that all tax cuts pay for themselves.

It’s a very clear and intelligent discussion of the subject. It only takes a few minutes to watch. I encourage folks to take a look at this presentation of supply-side tax policy.
