CAMBRIDGE – One of the biggest economic surprises of 2015 is that the stunning drop in global oil prices did not deliver a bigger boost to global growth. Despite the collapse in prices, from over $115 per barrel in June 2014 to $45 at the end of November 2015, most macroeconomic models suggest that the impact on global growth has been less than expected – perhaps 0.5% of global GDP.
坎布里奇—2015年最大的经济意外是全球石油价格暴跌并没有带来更大的全球增长提振。尽管油价从2014年6月的每桶115美元下跌到2015年11月底的45美元，但大部分宏观经济模型都表明，其对全球增长的影响要小于预期——只有全球GDP的0.5%。
