Michael T. Darda on the Deficit and Tax Receipts: "According to the Treasury department, the U.S. government took in a single-day record $61 billion in tax receipts on June 15. This surpassed the previous single-day high of $56 billion set on December 15, 2000. The recent surge in tax revenues is not just a one-day event. Fiscal year to date, total government receipts are up 15.5 percent, the fastest rate of increase on a comparable FYTD basis since 1981. The difference between the growth rate of tax revenues and the growth rate of government spending has widened to 8.4-percentage points, the largest since late 2000 when the budget was in surplus.
Not surprisingly, the recent tidal wave of tax receipts has ignited a furious debate about whether or not the Bush tax cuts are responsible for stimulating economic activity enough to actually boost overall tax-revenue collections. Classical economists refer to this as the Laffer curve, or the revenue-reflow, effect. In simple terms, if a tax cut stimulates the underlying activity being taxed, a revenue reflow will result. The reflow can offset or even surpass the volume of revenues that would have been collected under the higher tax rate and smaller tax base. Pro-growth tax-rate reductions on labor and capital in the 1920s, 1960s, 1980s, and then again in 1997 and 2003 all exhibited revenue-reflow effects, although some were stronger than others."
