Bear with me here. This is going to be one of those "out there" posts. But Steve Randy Waldman takes an interesting stab at a problem I've been wrestling with, at least in the furthest reaches of the financial corner of my brain, since the financial crisis began.
And that is how to stimulate the economy without creating another asset bubble. It sounds easy enough to the Keynesians, but as Waldman has pointed out before, rebooting aggregate demand through traditional government action may simply create another bubble. And ultimately, the distinction between monetary and fiscal policy may be moot.
