The only way Prediction-elect Donald Trump can deal with populism is to strike a balance between delivering its message and ensuring solid economic growth, according to Daniel Gros, head of research at the Center for European Policy Studies.
Trump wants to appear "not to be moderate, but in the substance, especially in the economic sense, (he needs) to remain moderate because he knows that's the only way he can deliver on growth," Gros told CNBC Tuesday.
"So the (U.S.) economic policy could remain ultimately rather prudent, but if the president makes it (grow fast) from time to time saying 'now we look after you', that might be enough," he added.
The increasing support for populism has been evident throughout 2016, not only in major events such as Brexit and the election of Donald Trump, but also in smaller state elections across Europe where such political parties have gathered a higher number of votes.
"Everything contributed a little bit (to populism)," Gros added.
