Post bump (understanding sticky wages and recessions)

I thought I'd give two neglected (IMHO, quality) posts a bump:

• Sticky wages, information transfer and piece work (Feb 2014) This is an attempt to understand the origin of sticky wages and questions Roger Farmer's assertion that wages were flexible in the Great Depression.

• The monetary base as a sand pile (Mar 2014) Some numerical differential equation solving and an analogy where NGDP is the height of a sand pile, the monetary base is the amount of sand and recessions are the inevitable avalanches that result as the height increases. Makes sense of these observations of NGDP.
