They need to send your boy back to Wharton because he's an idiot
[QUOTE=Dickhead; 427706]Here is an article by an economist who has a PhD from Wharton, normally considered to be both a top program and a fairly mainstream one. The author claims [B]and presents empirical evidence[/B] That tax rates and economic growth are unrelated. See what kind of holes you can poke in this.

I assume unlike Member #2041 that you don't disagree with that. The evidence is pretty clear cut that they slow economic growth.
You're an economist, I'm not. But doing a quick search in Google Scholar, there appears to be no argument that higher tax rates on companies reduce economic growth. Lee and Gordon (2005) estimate a 10% cut in the corporate tax rate increases economic growth by one to two percentage points. Other studies have similar results. That's gigantic, and I guess something you and Walleye already knew. Cut the rate on corporations to 0% and the tax on sole proprietorships, LLC's and Sub S's to 0% and we end up with East Asian levels of economic growth. I actually don't think the effect would be that profound, but am sure it would increase the GDP growth rate.
The data for the personal income tax is less clear cut. But as alluded to above, in the United States a large part of the personal income tax on the wealthy is actually tax on profits from businesses – sole proprietorships, LLC's and Sub S corporations. Higher tax rates on these businesses will slow economic growth, everything else being equal.
With respect to the mixed views on whether higher personal tax rates, exclusive of taxes on business, affect economic growth, they largely, like your link, don't take into account all the variables. They may not look at business conditions, education, globalization, technology, etc.
Most importantly, perhaps, some may not look at where we started and where we're going. COUNTRIES SEE GDP GROWTH FALL AS THEY BECOME MORE PROSPEROUS AND WEALTHIER. That's what's going on in the graph in your link. Lower tax rates are not causing GDP growth rates to fall. The only two countries that aren't special cases (oil rich, etc.) that I know of that have managed to maintain high rates of GDP growth as they've become wealthy are Singapore and Hong Kong. AND THEY HAVE LOW CORPORATE AND PERSONAL TAX RATES.
As I've pointed out here ad nauseum, if you compare compare high tax economies to low tax economies, the ones with lower taxes do better, all other things being equal. Compare Hong Kong and Singapore to any place in the world. And compare East Asian countries and the USA to Western Europe. Go through a list of the 10 countries with the highest GDP per capita in the world -- 7 or 8 of the 10, including the USA, have lower tax rates than Western Europe. And 6 have very low tax rates: http://en.wikipedia.org/wiki/List_of_countries_by_GDP_(PPP)_per_capita.
There's a fairness issue. How much are you going to milk people? Some would say 50% or 60% on high earners including state income taxes. I view that as robbery and in that scenario don't see much difference between the USA government and someone who hits you over the head and takes your wallet.
