The economic repercussions of September 11th are unique in that never before have economists needed to forecast and examine the impact of an event of such magnitude. This paper explains many of the economic effects of September l Ith, from the initial aftermath to recent developments. These effects are used to analyze the Colby Quarterly Econometric Model of the U.S. economy by simulating the model with actions taken by the government, such as an increase in spending, as well as other economic consequences resulting from September 11th. These simulations are then examined in more detail through multipliers that ultimately reveal the theoretical properties of the Colby model, which is found to differ from other models of similar nature. This paper contributes to the literature on macroeconornetric models by further examining their uses and limitations through a recent string of economic repercussions resulting from September 11th.
