In the estimation of the long run and the short run relationships among the variable s, the newly developed ARDL-ECM bound test procedure (pasaran, 2001) is employed. This approach is capable of testing for the existence of a long run relationship regardless of whether the underlying time series are individually 1(0) or 1(1) or whether the underlying time series are mutually 1(1) or 1(0). This enhanced the stability and robustness of our results. Accordingly, the results indicate that there exist a long run relationship between real GDP per capita and openness (trade/GDP). The long run estimated coefficient suggests that the impact of trade liberalization on economic growth has positive and significant but others variables real exchange rates (RER) and lab our force (LF) are in significant impact on real GDP per capita. The short run error correction model also confirm that the existence of the co-integration relationship between economic growth and trade openness. Further, the feedback coefficient indicate that a very high rate of adjustment towards long run equilibrium. The CUSUM and CUSUMQ stability test also indicate that the estimated long run Coefficient remain stable over the period of the study. Since trade liberalization is the long run process, from the study we suggest that in order to enhance growth the country should continue to liberalize their trade.eneconomics growthEthiopian test approachThesis
