Eight months after Donald Trump's shock election, economists and other social scientists remain at odds on his rise and that of right-wing populism in the west more generally.
So we have combed through recent papers on the political wave. Three of the most interesting ideas:
Harvard economist Dani Rodrik: we are watching the predictable result of more relaxed international trade and the rise of financial globalization.
Boston University's Douglas Kriner and Francis Shen of the University of Minnesota: if just three states had suffered fewer casualties in Iraq and Afghanistan, Hillary Clinton might today be president.
And James Montier, an asset allocation team member for GMO, the investment manager: crippling inequality explains the anti-establishment revolt.
