Re: Dickens on the Laffer Curve
That's the trouble with the empirical testing of Laffer effects. Your selected timeframe has an inverse relationship with the revenue maximizing rate of taxation. The tax policy that maximizes revenue over the next hour is to confiscate everything. The revenue maximizing tax policy over the next century is to tax at some lesser rate that anticipates the formation of capital to expand the tax base. Depending on the time frame you chose, you can conclude that t is currently on whatever side of t* you prefer so as to make the case for a tax cut or a tax hike. jlw Stephen Miller wrote: So it worked in the short run, and in the long run they were all dead!

Laffer Curve
I've been reading about Laffer's idea that there is a tendency for revenues to increase with increased taxation up to a point where revenue is maximized. As one of the class notes on Caplan's site indicates, you can derive revenue as a function of the tax rate and assuming that the slopes of the supply and demand curves are constants not equal to zero, you can show that the Laffer effect exists. For example, from Pd = price paid by buyer Ps = price received by seller t = tax per unit = Pd - Ps. R = revenue = tQ Supply curve: Qs = a + bPs Demand curve: Qd = c - dPd You can derive R = t(bc + da - bdt)/(b + d) Still, a lot of people have said that the Laffer curve is bunk. Are there any Laffer detractors here? If so, what must the supply and demand curves for labor look like for R(t) to be an always increasing (or at least never decreasing) function? James
