Analyzing the effect of military expenditure on economic growth has been an essential task for U.S economists. This thesis analyzed macroeconomic components for the last 70 years by estimating the ordinary least squares (OLS) regression model and vector autoregressive model. To interpret the empirical analysis, historical analysis of the Korean War, the Vietnam War, and the Wars in the Middle East, was made. One found the negative effect of military spending during wartime on the economic growth of the United States. This thesis suggests that the policymakers and military commanders should focus on shortening the state of war to minimize economic damage to the United States. / Includes bibliography. / Thesis (M.S.)--Florida Atlantic University, 2020. / FAU Electronic Theses and Dissertations Collection
