Earlier this week, Harvard economist Robert Barro and Veronique de Rugy of the Mercatus Center published a short paper assessing the economic effects of defense spending. Their findings are consistent with those of other studies, including one that Cato published last year by Benjamin Zycher. To wit, from Barro and de Rugy’s abstract:
American alliances are systems that transfer wealth from U.S. taxpayers and their debtors to citizens in wealthy allies. With Uncle Sam paying for those countries’ defense, their governments are free to use their own revenues for welfare programs or other domestic priorities. This is a sucker’s bet from an American perspective, but pretty great from the perspective of the citizen of a rich country who benefits from this largesse.
