Investopedia:
Trump economic uncertainty worse than 2008 crisis
22 May 2017
Increases in policy uncertainty "foreshadow declines in investment, output and employment in the United States," according to the developers of the Economic Policy Uncertainty Index, professors Scott R. Baker of Northwestern University, Nicholas Bloom of Stanford University and Steven J. Davis of the University of Chicago, CNBC reports. As measured by the EPU index, the election of Donald Trump as president so far is the third most uncertainty-inducing event for the U.S. since the beginning of 1985, CNBC reports, sending it to an average value of 254 in November.
