This paper analyzes the economic impact of public emergencies from the perspective of aggregate demand shocks. The analysis in this paper shows that the events of 9/11, SARS and Hurricane Katrina all have an impact on the total demand. This paper argues that the causes of the impact of aggregate demand mainly lie in the anticipation of economic subjects and the change of economic behavior caused by public emergencies.
