 A Portfolio Diversification Model of AlliancesJohn A. C. Conybeare
Journal of Conflict Resolution, 1992, vol. 36, issue 1, 53-85 Abstract: The theory of finance demonstrates that diversified investment portfolios produce superior combinations of risk and return, and that investors may choose a portfolio reflecting their preferred mix of risk and return. These techniques may be applied to military alliances. The rate of return and risk of an ally follows a positive linear relationship, as predicted by capital asset pricing theory. Random diversification of allies will, as with investment portfolios, reduce the country-unique components of alliance risk toward that which is inherent in the system as a whole. Some alliances will be more efficient at producing greater return and lower risk. The most efficient alliances will be those in which variations in ally effort move in opposite directions. Development of the demand side of portfolio analysis may predict which alliances are optimal, and therefore most likely to form. These principles are applied to the Triple Entente and Triple Alliance between 1879 and 1914. It is suggested that the Entente had superior efficiency characteristics and that ally choices were consistent with demand patterns.
