This work is part of a wider Office for National Statistics (ONS) strategy to produce the inputs required for multi-factor productivity calculations. Therefore the two prime aims in producing this measure are firstly its use as an input to multifactor productivity analysis and secondly to develop a measure of labour input which explicitly takes into account changes in the composition of skills in the economy.
The results are presented in the form of both quarterly Tornqvist and annual Laspeyres indices.
