Niall Ferguson, a history professor at Harvard, and Moritz Shularick, a economic history professor at the Free University of Berlin, coined the term Chimerica, to describe the Chinese export machine and the American overconsumption right down to negative savings. Now they call it an economic monster that needs to be given a burial. It does little good for America. For America its a 10-10 deal the authors say, 10% growth for China and 10% unemployment int the USA. The mood in the USA is no longer to go on with this arrangement they warn, and ask that the Obama administration take steps to end this arrangement. The USA should ask China to make a 30 % depreciation of the renminbi say Ferguson and Schularick. Krugman makes a similiar point and warns of dire consequences in aworld out of balance on the same page of the NYT, see the link. Ferguson and Schularick point out that unlike China, both Germany and Japan let their currencies appreciate by 60% for Germany and 50% in Japan, at a similiar period in their country's development. China's renmibi is pegged at 6.83 renminbi to the dollar, and China's government used $300 billion in reserves to keep the renminbi from appreciating this year. Throughout the 1980's and 1990's it was pegged at around 8.28 renminbi to the dollar. For the USA this has been very costly, with a distortion in the global cost of capital significantly reducing long term interest rates, and helping create the real estate bubble in the US. They point out that with Japan and Germany dollar reserves increased roughly in line with growth of American GDP at about 1% and stable before moving slighltly higher in the 1970's. By contrast China's reserves have grown from about 1% of Ameica's GDP in 2000 or $165 billion to 5% in 2005 and 10% in 2008 and headed for 12% in 2009 end. This is simply unsustainable any longer; carrying on any longer risks China losing the very basis of its economic success which is the open global trading system....
