Higher levels of codetermination correlate with greater national equality.
"Out of this, the previously stated hypothesis can be confirmed by the analysed sample of EU countries. This strongly supports Vitols (2005) results, which indicated a negative bivariate correlation between the existence of a compulsory codetermination system in the private sector and the level of the Gini index. Correspondingly, it is fair to conclude that states with codetermination inhabit a more equal distribution of incomes than states without employee representation in the board of companies in the private sector. This supports – on the macro-level – the results found on the micro-level by Gorton & Schmid (2002), stating that codetermination has an impact on the wage level in German companies."
