Abstract
The article presents the underlying principles, derivation and properties of a simple descriptive measure of concordance between two analogous rank structures that we call the coefficient of structural concordance. It is based upon the idea of Kendall's coefficient of concordance, which we extend to two rank structures. As the coefficient of structural concordance is a pure intergroup measure of concordance, it is designed to complement the Kendall's intragroup coefficient of concordance. We apply this descriptive measure by exploring the relationship between wages and labour productivity in Slovenia for the period 1998-2007. We are able to confirm the hypothesis of high concordance between wages and labour productivity, which indicates a stimulative role of wages in production of market traded goods and services.
Highlights
In science, we often deal with the issue of agreement or concordance in a relationship between phenomena under consideration
We explore the linkage between wages and labour productivity, basing our analysis upon industry data on gross wages and value added per employee in Slovenia for the period 1998–2007
Since the rank structures of gross wages and value added per employee have an even number of ranks, we shall use expression (5)
Summary
We often deal with the issue of agreement or concordance in a relationship between phenomena under consideration. The prerequisite for precise measurement of concordance is the availability and quality of data on the phenomena under consideration. In this article we develop one such measurement based upon the underlying principle of Kendall’s coefficient of concordance. We call this measurement the coefficient of structural concordance. In the final section we summarize the central findings of the article
