Matias Vernengo debunks the expectations and confidence fairies

There are confidence fairies and there is the inflation expectations fairy. It's a 4% fairy apparently. I'll explain. So Krugman correctly points out always that the more fundamentalist neoclassical economists (the Talibans that love price flexibility and instantaneous adjustment to full employment, not the moderates that also believe in a natural rate, but think it takes a while to get to it like Krugman himself) believe that the economy would recover if only a proper environment for investment was created. Hence, if confidence returned we would have a recovery.
They obviously invert causality between confidence and recovery. As noted by Marriner Eccles long ago: "confidence itself is not a cause. It is the effect of things already in motion. (...) What passed as a 'lack of confidence' crisis was really nothing more than an investor's recognition of the fact that new plant facilities were not needed at the time." Investment is the result of a growing economy, in which firms tend to adjust their capacity to demand. No demand for your goods no need to invest to create capacity to produce more. Plain and simple.
