It is not a surprise for anyone that the recent 16-day long partial government shutdown and political disputes will have a devastating effect on the world's largest economy; however, mounting polarization of U.S. politics imperils the long term growth. During the shutdown a report from Gallup showed Republican's poll numbers are hitting historic low, as its favourability rating dropped to 28%- the lowest for any party on record. Hence, an economist from the Federal Reserve Bank of Philadelphia, Marina Azzimonti, tried to find a correlation between economic growth and the tone of political debate. The so-called political polarization index is based on news and articles to measure the coverage of lawmakers' disputes from January 1981 and up to April 2013. The measure inched higher during the 2008 recession and peaked closer to 2012. During the last year the measure soared to about 75 in 1981 to almost 200. A more practical implementation of this index is that as a result, it estimates a loss of almost 1.75 million jobs during the last six quarters. Furthermore, investment plunged 8.6%, while output sank 2%. As long as U.S. politicians will not be able to reach a consensus, despite all efforts from the Federal Reserve, the world's largest economy may struggle to build up steam.
