 Passage 3:In an open letter to the President, the Congress, and the American people, eighty economists, including Nobel Laureate Vernon L. Smith, stated that the FairTax would boost the United States economy. According to the National Bureau of Economic Research and Americans For Fair Taxation, GDP would increase almost 10.5% in the year after the FairTax goes into effect. Real investments could increase by as much as 76% initially and remain 15% above present levels. In addition, the incentive to work would increase by as much as 20%, the economy's capital stock would increase by 42%, labor supply by 4%, output by 12%, and real wage rate by 8%. A study in 2007 by the Beacon Hill Institute of Suffolk University stated that within five years real GDP would increase 10.7% over the current system, domestic investment by 86.3%, capital stock by 9.3%, employment by 9.9%, real wages by 10.2%, and consumption by 1.8%. Laurence Kotlikoff of Boston University finds that the shift to the FairTax would raise marginal labor productivity and real wages over the course of the century by 18.9% and long-run output by 10.6%. Further, studies of the FairTax at Boston University and Rice University suggests the FairTax will bring long-term interest rates down by as much as one third. As falling tax compliance costs lower production costs, exports would increase by 26% initially and remain more than 13% above present levels. According to Professor Dale Jorgenson of Harvard University’s Economics Department, revenues to Social Security and Medicare would double as the size of the economy doubles within 15 years after passage of the FairTax. Wall Street Journal columnist James Taranto states the FairTax is unsuited to take advantage of supply-side effects and would create a powerful disincentive to spend money.
