摘要

在这项工作中，我们描述了新的指挥区域，它通过采用基于几何的方法，提供了一种生产力衡量标准，充分考虑了同一行业内企业之间现有的异质性。我们提出的方法还能够评估多维异质性的程度，并应用于生产分析之外的领域。最后，我们详细介绍了该软件的功能，以进行相关的实证分析，并讨论了在其开发过程中遇到的主要计算问题。

A toolbox for measuring heterogeneity and efficiency using zonotopes

In this work, we describe the new command zonotope, which, 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. The method we propose also enables assessment of the extent of multidimensional heterogeneity with applications to fields beyond that of production analysis. 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.
