The socialization of military power: security cooperation and doctrine development through multinational military exercises

Multinational Military Exercises (MMEs) are often viewed by states as opportunities to increase interoperability, improve cooperation, and solve common security problems. We argue that in addition to this, MMEs work as tools to shape the shared beliefs of coalition partners surrounding threat. Specifically, MMEs allow multinational forces to identify best practices, consolidate beliefs, and codify behavior through doctrine, typically by means of some institutional process. We examine our argument on MMEs through an analysis of various multinational and coalition partner efforts to identify security threats and cooperate through the development of common doctrine at the strategic, operational, and tactical levels of warfare. Our analysis suggests that the use of MMEs for doctrine development does help to socialize states in terms of identifying common threats and subsequently sharing a process by which to address them.     

Defense–Growth Causality: Considerations of Regime-Switching and Time- and Country-Varying Effects

This paper develops a panel smooth transition vector autoregressive model to investigate the economic growth–defense causality. This model simultaneously resolves the estimation problems of endogeneity, heterogeneity, and nonlinearity. Empirical results support that the causality is bidirectional, nonlinear, time- and country-varying. Economic growth has a negative impact on military spending and vice versa. The larger the HDI, the smaller the negative causality. Evidently, the increase in the level of country development can reduce the negative impact of military outlays on economic growth. Reducing the ratio of military spending to GDP is beneficial for countries with low HDI scores; however, moderately increasing the share of military expenditure is favorable for countries with extremely high HDI scores. Policy authority needs to set optimal education, health, and economic development shares of GDP for purchasing a maximum economic growth rate.
