Abstract: Tax reduction shocks in US economy: 1964, 1979-81 and 2002 increased gross domestic product, GDP, in the short run (≈ 3 years) so that 1% reduction increased the detrended GDP with 0.48 – 0.77 %. Following tax reductions, tax series became a leading variable to GDP for 9 to 15 years completing 1 to 2 cycles. However, in the long run, ≈ 10 years, 1 % tax reduction decreased the detrended GDP with about 0.25 %. However, tax, as Government recipts, and GDP are both composite measures so it is not unlikely that the effects may be attributable to specific components of the tax or GDP. I used a novel technique that identifies running leading relationships between time series, extracts common cycle lengths from the series and estimates lag times.
