Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.
Here is Bruce Bartlett again arguing against the Laffer Curve (again, back in March):

how likely is it that the Laffer curve is causing revenues to rise, as opposed to normal operation of the business cycle? Not much, in my opinion.

First of all, the Laffer curve came to prominence during a period when the top tax rate on dividends was 70 percent, and the rate on long-term capital gains was 40 percent. Economist Arthur Laffer correctly pointed out that a 100 percent tax rate would raise no revenue and that rates close to this would reduce revenue below what a lower rate would bring in. Given the tax rates in existence, it was plausible to argue that a reduction in the top rate and capital gains tax would raise revenue.

However, when President Bush took office, the top rate on dividends was down to 39.6 percent, and the rate on long-term capital gains was just 20 percent -- far below the rates Ronald Reagan inherited. It is very implausible that these rates were in the "prohibitive" range of the Laffer curve, such that a rate reduction would raise revenue.

But even if we grant the theory, how likely is it that the recent rise in revenue owes anything to this effect? Again, not much.

The fact is that it is only in very exceptional circumstances that there would even be the possibility of a tax cut that would so stimulate growth that it would pay for itself. Even the Bush Administration admits this. The 2003 Economic Report of the President  says, "Although the economy grows in response to tax reductions ... it is unlikely to grow so much that lost tax revenue is completely recovered by the higher level of economic activity."


Revenues as a share of the gross domestic product fell every year from 2000 to 2004, from 20.9 percent to 16.3 percent. The 2005 increase only raised revenues to 17.5 percent -- still well below their historical average of 18.1 percent of GDP. It seems to me that the normal cyclical expansion after the end of the recession in 2001 has done far more to raise revenue than any Laffer curve effect. Revenues are simply returning to trend, nothing more.

Truth unfolds in time through a communal process.
