Economic Growth’s Catalyzing Effect on War

ABSTRACT This paper explains the circumstances where economic growth increases the likelihood of interstate war. Optimism created by high and sustained economic expansion permeates a state, increasing elite and mass optimism for the use of deadly force. Without relief, such unbridled sanguinity can lead states to war. However, other forces reduce the probability of war. Regional democracy, bilateral trade, and trade openness slow down the process where states go to war. This paper hypothesizes that key factors raise the temperature of disputes, increasing the likelihood of a political dispute combusting to war, while other attributes inhibit the process to war. Economic growth catalyzes such reactions, while regional and joint democracy impede the probability that a war sparks. This paper produces monadic and dyadic results demonstrating that economic growth increases the likelihood of war, while other factors such as interstate trade openness, bilateral trade, dyadic democracy, and regional democracy slow down the process of war, making war less likely.
