Ernest Aves (1857-1917) was an influential social analyst and civil servant. This title, first published in 1907, during Aves' work for the Board of Trade, investigates the different forms of industrial co-operation within Britain; the fundamental principle of this is stated as "equitable association", leading to increased profitability and the strengthening of industry. Chapters discuss such areas as centralisation, co-operative production and co-operative agriculture. This interesting reissue will be of particular value to students of economics with an interest in co-operative industry and the history of economic thought.
