First published in 1930, John Hobson's study deals with the economic dilemmas generated in the early twentieth century by the advent of mass production. Namely the over-production and surfeit of goods and the resultant failure of the expansion of markets leading to record levels of mass unemployment.

Seeking a solution to this dilemma, Hobson analyses all aspects of the problem: income, uses of the surplus, underconsumption, markets and distribution, and internationalism. The study also explores theories concerning economies of rationalisation, both in terms of productivity and consumption.
