The study investigates the economic dimensions of war. It considers empirical literature through structure review to explore the different effects of war on businesses.The scope of the study covers all geographical areas and studies dealing with any respective event in the 20 th and 21 st centuries. However, the study caters for quality, relevance, and recentness in publications. Hence, publications in 4*, 4, and 3 stars journals that are placed in Association of Business Schools of UK Guidelines in 2015 are reviewed.
