A Naive Model on the Rise and Decline of Nations and Powers

In this paper, I offer a Schumpeterian model on the rise and decline of nations and empires. The model sheds light on why different nations can reach very different equilibrium states in terms of economic strength and military prowess, how the initial condition, the chance of military campaign, personal charisma or leadership, the national spirit, the will to power, the Schumpeterian innovations, and the e¡èective desire of accumulation affect the rise and decline of nations.
