Decompositions of Productivity Growth into Sectoral Effects

The paper provides some new decompositions of labour productivity growth and Total Factor Productivity (TFP) growth into sectoral effects. These new decompositions draw on the earlier work of Tang and Wang (2004). The economy wide labour productivity growth rate turns out to depend on the sectoral productivity growth rates, output price effects and changes in sectoral labour input shares. The economy wide TFP growth decomposition is similar but some extra terms due to input price inflation make their appearance in the decomposition.
