%X this paper presents a new mathematical method for constructing abstract labour as conceived by karl marx, in a general input-output model with joint production and heterogeneous labour. a brief history of previous efforts to define and compose abstract labour using input-output models is also described. a numerical example is given to show how our method works in a concrete way.
