Can political leaders influence macroeconomic expectations on a global scale? We design a large-scale survey experiment among influential economic experts working in more than 100 countries and use the 2020 US presidential election as a quasi-natural experiment to identify the effect of the US incumbent change on global macroeconomic expectations. We find large effects of the change in US leadership on growth expectations of international experts. The effect works through both economic (more positive expectations about trade) and psychological (irrational exuberance at the defeat of an unpopular but powerful leader) channels. Our findings suggest important political spillover effects in the formation of macroeconomic expectations.
