Extensive stage, or by its full name, predominantly extensive stage of accumulation is pertains at one of the periodizations of capitalism, as proposed by Aglietta (1976). It is the first stage of capitalism and thus in it there is plenty of room for the extension of capitalist relations of production, meaning, of wage labour and therefore of commodity production. In other periodizations this is known as early or concurrential stage. It is characterized by high rates of growth (runaway, unfettered).
