美国总统经济顧问委员会最近发表报告,宣布今年第一季国民生产总值的年率为4,270亿美元,比去年第四季的年率4,238亿美元增加了32亿美元;同时,又宣布今年3月份的个人收入也已从去年12月的3,340亿美元增到3,375亿美元(年率)。因此,有一些美国经济学者便以此作为证据,对于美国经济的前景发表了许多乐观的论调,认为1957年美国经济比1956年还要“繁荣”。但是这些证据能令人信服吗?
The U.S. President’s Council of Economic Advisers recently released a report announcing an annual rate of GDP of 4,270 billion U.S. dollars in the first quarter of this year, an increase of 3.2 billion U.S. dollars from the annual rate of 4,238 billion U.S. dollars in the fourth quarter of last year. In the meantime, Personal incomes have also risen from 3,342 billion U.S. dollars in December last year to 3,375 billion U.S. dollars (annualized). Therefore, some U.S. economists use this as evidence to make many optimistic arguments about the future of the U.S. economy and think that in 1957 the U.S. economy was “prosperous” than in 1956. But can these convincing evidence?
