Since the 1950s the United States has been considered a superpower due to its commercial might. The condition of the American economy determined the condition of the world economy– such was the impact of this one large economy. During the recession in 2008, markets collapsed and struck most of the world. But to some countries, especially China, the effect was minimal as compared to the rest of the world. The after-effects of this recession have continued till today with unemployment at all-time highs in 2013 and economic growth rates struggling to rise.
2014 promises a better situation for the US economy which is reflected in job creation as well. This presents a better outlook for the world economy as well, even today. The world economy is expected to grow 3.6% in 2014, which is up from 3% in 2014, as forecasted by the IMF. This has been attributed to better performing developed economies, mainly the US.
So, as we see the dependence of the world economy on that of the US still remains, but not to the extent it used to be. In the 1980s America’s economy accounted for 1/4th of the world output, while today it only accounts to 1/5th. This is thanks to the emerging markets like China, India & Brazil who are now contributing a larger portion to the world economic output.
As other economies emerge from poverty and lack of education, the share of the world economic activities contributed by the US will further reduce, and this presents a new challenge to managing macroeconomics, which would now involve many more factors than before.
