3. You came across a recent (24 April 2024) News24 article, "The DRC had the world’s biggest military spend increase last year—and South Sudan was second.” You are worried about the increasing defence expenditure of African countries at war and its impact on economic growth. You collect data for one of the countries from 1980 to 2023, and you estimate the following model: Dependent Variable: Gross Domestic Product (GDP) Explanatory Variables Coefficient Standard Error Constant 0.0486 0.0242 Lagged GDP (GDPt-1) 0.6527 0.0813 Capital Investment (CI) -0.0025 0.0012 Labour (L) 0.0246 0.0074 Defence expenditure (DE) 0.5883 0.0648 Inflation (INF) 0.0272 0.0152 Recession Dummy (REC) REC = 1: Recession REC=0: No recession -0.0441 0.0254 R-Squared 0.894 Dw-d = 1.654 F-Stat = 27.84 a. What are the expected signs of the variables in this model? Explain. (6) b. Interpret the estimated coefficients of CI, INF and REC (6) c.
