Before revision: Sector-wise productivity growths are measured, along with the sectoral elasticity of substitutions, under the multi-factor CES framework, by regressing the growths of factor-wise cost shares against the growths of relative factor prices.
After revision: Sector specific multifactor CES elasticity of substitution and the corresponding productivity growths are measured, along with the sectoral elasticity of substitutions, under the multi-factor CES framework, by regressing the growths of factor-wise cost shares against the growths of relative factor prices.
