Irrational Human Irrational Economics

Gurus are saying don’t worry be happy, the economy is irrational so as the human being are; it can not be analysis number alone.  Here Krugman says, the economy stuck into “option value: the short rate could move up, but it can’t go down, so the yield curve has to be upward-sloping”:

… any further decline in expected inflation — which has plunged lately — will translate into a rise in real interest rates. And that will be a drag on the economy, leading to further inflation declines. Basically, we can get into the functional equivalent of a deflationary trap long before we reach actual deflation. And it starts around now.

So it can not be that bad, somehow this irrational thing along the way travels upward it may be cured itself along nicely. Could we just bit of narrative things that are bit of out of control? Anyway economic are human story itself therefore human are irrational. So don’t worry the tumbling market be happy!!
