Why Has the Stock Market Risen So Much Since the US Presidential Election?
This paper looks at the evolution of U.S. stock prices from the time of the Presidential elections to the end of 2017.

A general improvement in economic activity and a decrease in economic policy uncertainty around the world were the main factors behind the stock market increase.

However, the standard new Keynesian framework implies no such trade-off. In that framework, stabilizing inflation is equivalent to stabilizing the welfare-relevant output gap. In this paper, we argue that this property of the new Keynesian framework, which we call the divine coincidence, is due to a special feature of the model: the absence of nontrivial real imperfections. ; We focus on one such real imperfection, namely, real wage rigidities. When the baseline new ...
