Abstract

Multicollinearity is one of the major methodological problems in the study of the guns-growth tradeoff. In this paper, we use ridge regression to separate the effects of individual variables influencing economic growth in the United States. Ridge is not a new method, but to the best of our knowledge, this is the first application of ridge regression to the study of national security or Defence and Peace Economics.
