commodity will fall in such a situation of
overproduction. The same thing happens in
the case of other commodity.
Iv. Over saving THEORY

cycle. It was propounded by socialistic-minded economists
like major Douglas and J.A. Hobson. According to this
theory, is the inequality of income that prevails in a
capitalistic society. Thus, too much saving and too little
consumption is the cause of business depression according
to this theory.

oversaving and underconsumption.

investment in industrial equipments
