A proposal for decomposing and adjusting the conventional Divisia index for the measure of productivity


  • Rodriguez, X.A.



This paper proposes a general framework for decomposing (without incorporating restrictive assumptions) the conventional Divisia index of productivity into for types of effects: technological, subequilibrium, scale, and so -called "market" effects or mark-ups. We believe, however, that this last component is due to a "defect" in the aggregation of the productions in the Divisia index itself, in situations where the conditions of long-run competitive equilibrium are not meet in the product markets. Therefore we adjust the index and conclude with a decomposition equation (with technical subequilibrium and scale effects) which is flexible and generic. Use of the framework is illustrated empirical for the Spanish energy mining sector.
