Trump must overcome global barriers to deliver his economic promise | Mohamed El-Erian

As well as promoting growth at home, the president-elect must coordinate policy with Germany, China and Japan

Donald Trump should have a relatively clear road ahead at home for the implementation of his economic programme: with Republicans holding majorities in both houses of Congress, he seems likely to benefit from a break in the political gridlock that has paralysed the body for the last six years. But the US economy does not exist in a vacuum. If Trump is to succeed in delivering the high growth and genuine financial stability that he has promised, he will need some help from abroad.

Trump has established infrastructure investment, tax reform, and deregulation as central components of his strategy to boost the US economy's actual and potential growth. Confident that his plan can unfold as intended, he has set ambitious targets, including GDP growth approaching 4% a year.
