RE: so where's the curve?
Unfortunately, Woodhill didn't show it in this article.
But here's the original Laffer Curve for those who want a review:
Here's another version :
\
If the tax rate is 0%, we get zero revenue. If the tax rate is 100%, we also get zero revenue, or near to it, because no one will work. In the middle somewhere is a maximum, labeled "Equilibrium Point" in the diagram. Perhaps it's skewed more than the figures above shows, but it's in there somewhere.
I expected Woodhill to display his "curve" so we could see what he's talking about; he refers to it repeatedly in his article. The great Dr. Art Laffer’s Curve is magnificent in its simplicity.
