In this work we describe a new stata command zonotope that, by resorting to a geometry-based approach, provides a measure of productivity that fully accounts for the existing heterogeneity across firms within the same industry. Further, the method that we propose also enables to assess the extent of multi-dimensional heterogeneity with applications to fields beyond that of production analysis only. Finally, we detail the functioning of the software to perform the related empirical analysis and we discuss the main computational issues encountered in its development.

Abstract
In this work we describe a new stata command zonotope that, by resorting to a geometry-based approach, provides a measure of productivity that fully accounts for the existing heterogeneity across firms within the same industry. Further, the method that we propose also enables to assess the extent of multi-dimensional heterogeneity with applications to fields beyond that of production analysis only. Finally, we detail the functioning of the software to perform the related empirical analysis and we discuss the main computational issues encountered in its development.File in questo prodotto:
