Tyler Cowen is a creative economist.  Here, he proposes a novel approach to Europe.  The key paragraph:

Just to make the comparison biting, what if we postponed the costly benefits part of ACA for a year (it may be struck down anyway) and send $200 billion directly to Spain and its banks?  Is more money needed?  Use this as an excuse to get rid of farm subsidies and cut defense spending.  Surely the Germans would then chip in too, and perhaps even the Chinese, if we made the donors club sound exclusive and toney enough.  Drop hints about various silly islands (not Taiwan).

You could make an economic argument that this is a way to go, but I’m pretty sure the politics would be really tough.
