Part of the equation in sub-section “Key findings” is missing in the original publication of the article. The error was caused by the fact that the equation, due to its length, exceeded the page width. The missing part of the equation is given below:

The right-hand side equals:

$$ \alpha_{1} {\text{RankBarg}}_{i} \cdot \Delta^{j} {\text{RelPos}}_{j} + \alpha_{2} {\text{RandmContr}}_{i} \cdot \Delta^{j} {\text{RelPos}}_{j} + \alpha_{3} {\text{RankContr}}_{i} \cdot \Delta^{j} {\text{RelPos}}_{j} + \left( {\Delta^{j} {\varvec{X}}_{ij} } \right){\varvec{\beta}} + \Delta^{j} \varepsilon_{ij} . $$

The original article has been updated.
