Barro and Lee study on the factors affecting economic growth from 1965 to 1985 in a large cross-section of countries find that there is an insignificant relationship between war and economic growth. Nevertheless, they infer the nonsignificance to a lack of variables that measure the seriousness of the wars. Based on Barro and Lee study,TOm investigates the economic significance of civil war but conditions the relationship between war and growth using war duration and finds that prolonged wars contribute towards higher economic growth. Murdoch and Sandler also investigate the impact of civil wars on economic growth bit include several characteristics of war. They find that civil war has an inverse relationship on short-term economic growth, whilst no relationship is document on the long-effect of war on economic growth.
