Question: Who founded the institute that in 2007 stated that within five years real GDP would increase 10.7% over the current system? Passage 1:DeFilippo became quarterbacks coach at Fordham in 2000 upon graduating from James Madison. The following year, DeFilippo enrolled at the University of Notre Dame to be a graduate assistant for the Notre Dame Fighting Irish. In the 2001 season, DeFilippo helped coach wide receivers and tight ends on Bob Davie's staff, then in 2002 worked with quarterbacks under Tyrone Willingham. From 2003 to 2004, DeFilippo was again quarterbacks coach at a Division I-AA program in New York City, Columbia, under Bob Shoop. He then moved up to the NFL in 2005 as offensive quality control coach for the New York Giants under Tom Coughlin and held that position until 2006. In 2007, DeFilippo joined Lane Kiffin's staff on the Oakland Raiders as quarterbacks coach and remained on staff in 2008 when Tom Cable replaced Kiffin during the season. DeFilippo became quarterbacks coach for the New York Jets under Rex Ryan in 2009. The Jets that year finished 9-7 and in the playoffs, defeated the Cincinnati Bengals and San Diego Chargers to make their first trip to the AFC Championship Game in 11 years, before losing to their former division rival Indianapolis Colts 17-30. DeFilippo also coached rookie quarterback Mark Sanchez, whom in 2009, became only the second rookie quarterback in NFL history to win multiple playoff games.
Passage 2: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.
Passage 3:Manuchar I Jaqeli () (1452 died after 1518) was a Prince and Atabeg of Samtskhe-Saatabago from 1515 to 1518. He was a member of the Jaqeli family and youngest son of Qvarqvare II Jaqeli. After his older brother Mzetchabuk's abdication Manuchar started an uprising against his nephew Qvarqvare, the son of Kaikhosro I. Manuchar's revolt finished successfully and he ascended to the Meskhetian throne. During his brief reign Manuchar sent many gifts to the Ottoman sultan Selim I and claimed himself as an admier of Ottomans. In 1518 the new revolt started. Prince Qvarqvare with the help of Safavid troops attacked Samtskhe. Manuchar was overthrown and Qvarqvare became the new ruler of Meskheti. After this Manuchar asked his suzerain Sultan Selim for help. Sultan gave him the huge army. He had tried to restore himself as Atabeg, but was defeated by Qvarqvare's forces at the battle near Erzurum. Manuchar Jaqeli escaped to the Ottoman empire and lived there until his death. Nothing is known about his later life and descendants.
