Do tax cuts pay for themselves?

From The New York Times (see second page):

Politicians sometimes say that lower tax rates lead to higher economic growth, which in turn leads to higher overall tax revenue. This may have been true in the early 1960s, when the top tax rate was 91 percent, but the top tax rate today is 35 percent. For decades, lower tax rates have led to lower government revenues, says Alan Viard, an economist at the American Enterprise Institute, a conservative policy group. “The Reagan tax cuts, on the whole, reduced revenue,” he explains. “The Bush tax cuts clearly reduced revenue. There is no dispute among economists about that.”
