I would agree--- with one amendment: 'forms_through which absolute surplus value can be increased' >They also _should_ be differentiated for the following reason: >an increase in the intensity of labor increases output/worker/period of >time whereas an increase in absolute surplus value does not. If you indicate the period as a workday without specifying its length, the result is the same when you increase the workday or increase its intensity. In both cases, output per worker increases; and, in both cases, the worker gets tired. This is to be distinguished from pure increases in productivity, where output per worker rises but there is no additional expenditure of units of labour. In fact, an important challenge is to separate increases in productivity from speedup--- which is why accident rates seem interesting as a proxy. > > If the > > workday were lengthened (eg., by 10%) and intensity fell by 20% > > (ie., big pores open up) on the whole, wouldn't that reduce absolute > > surplus value? > >No. by your limited definition > > As for measurement (a very important question), I seem to > > remember (way back-- 80s?) the use of accidents as a proxy (which > > made a lot of sense to me).
