纽约大学斯特恩商学院经济学教授、末日博士努里尔·鲁比尼(Nouriel Roubin)i在发表评论文章认为,全球目前经历的放缓是顽固的,因为深陷欧元危机的国家无力偿还债务、而美国放缓的因素是慢性的;与此同时,由于通胀水平上升、债务负担过重,各国无法通过刺激政策使经济提速。如果政策制定者真的变得无计可施,诸多发达经济体经济失速和直接出现双底衰退的几率将大幅提高。 Nouriel Roubin, a professor of economics at Stern School of Business at New York University, said in a commentary that the slowdown currently undergone in the world is stubborn because the countries deep in the euro crisis are unable to repay Debt, while the slowdown in the United States is chronic; at the same time, countries can not boost their economies through stimulus policies because of rising inflation and debt burdens. If policy-makers really become overwhelmed, the chances of economic stagnation and direct double-dip recession in many advanced economies will rise sharply.
