The crisis in the eurozone, and the bizarre failure of the European Central Bank (ECB) to even try to manage it, has united strange bedfellows in arguing that the United States Federal Reserve should begin acting as in loco Responsible Central Bankis for the eurozone.

Brad DeLong argued a week ago for the Fed to begin buying up Italian and Greek debt to avoid a financial crisis potentially as big or bigger than the fallout from Lehman’s collapse in 2008. Dean Baker and Mark Weisbrot, often skeptical of finance-centric explanations of (and solutions to) the ongoing jobs crisis over the years since the Great Recession began … agree wholeheartedly.

Yes, as a general rule, economists agreeing with each other is usually a recipe for other people to begin reaching for their own wallets, but this group is both smart and (much) more importantly right on this specific issue. If the ECB won’t act like a central bank, and if the absence of a central bank in the eurozone threatens American economic growth (and it does – the eurozone is a crucial export market for the U.S. and fallout from U.S. banks holding eurozone could indeed be ugly), then it makes sense for the Fed to step in.

It would be really helpful, by the way, to have the two current vacancies on the Fed’s Board of Governors filled by people who were consistently arguing for aggressive actions to stem the economic crisis.
