Who among the following viewed unemployment as outcome of the disorganization of economic system ?

Lionel D. Edie viewed unemployment as the outcome of disorganisation of the economic system, that is, a failure in the working of the economic order rather than a fault of individual workers. Fairchild defined unemployment as forced and involuntary separation from remunerative work of the normal working force during normal working time at normal wages, and Karl Pribram described it as a condition of the labour market in which the supply of labour exceeds the available openings.
