The “Guns or Butter” model is a simple economics concept that describes the tradeoff governments face in spending on national defense or on domestic programs. The model is meant to highlight the spending constraints faced by governments – they must choose between the two. For several decades, Europe has chosen butter, relying on America to provide a defense of the continent.
Now, a combination of events, Russia’s invasion of Ukraine, war in the Middle East and an increasing realization that Washington might not be as reliable a partner as previously thought (hoped?), has forced Europe to contemplate providing for its own defense.
This is a dilemma that cannot be easily or quickly resolved. For example, Europe’s gold standard pension plans and other generous social programs assumed that a growing number of young workers would support a relatively small group of retirees. Changes in demographics have also changed all that, as the number of pensioners has grown relative to the number of younger workers, and people are living longer, leaving a pension and benefits system that can’t keep up. Even if Europe can find the money, by curtailing social programs (not likely), and/or raising taxes, building an effective military will take several years. Moreover, Europe is a collection of countries that, even now, have difficulties in coordinating a complicated and diverse military establishment. Witness the recent disagreements as Europe attempts to understand the conflict with Iran.
Investors will have plenty to digest as European economies seek to resolve the guns versus butter issues. Perhaps the more immediate concern might be the use of deficit spending. Most economists would expect this to result in more inflation. If that isn’t enough, Europe has a serious energy problem with rising prices and the risk of shortages.
