Input-output provides features for the measurement and analysis of tot
al factor productivity (TFP) growth. First, TFP growth can be measured
using gross output and incorporating materials as an input. Second, a
growth accounting framework can be developed to measure the effect of
final output mix changes on aggregate productivity growth. Third. cap
ital can be treated as a produced means of production. Fourth, measure
s of composite technical change can overcome difficulties engendered b
y the substitution of externally provided inputs for those previously
provided by the firm. Fifth, TFP growth of secondary production can be
analytically separated from that of primary output.
