5. RESULTS AND DISCUSSIONS 5.1 Unit Root Test Results Unit root test was the first test done on each of the independent variables in both models to check for stationarity. As putting the result of each test here would make it congested, the T-static and probability values from the results are selected from each result and compiled in the tables hereunder. The unit root test results for each variable are attached in the appendix. Table 5. 1 Result of unit Root Test for Recurrent-Capital Expenditure and GDP Variable Level 1st Difference Stationary at T-Static Prob. Decision T-Static Prob.

The test performed for variables for Model II (including the sectoral expenditure) assumed the some of the series to have trend while some are stochastic in the series with ‘Intercept and trend in CE – no trend in VAR’ trend specification selected, and one lag used in differences (two lags in
