Deutsche Bank in his report on competitiveness noted the following:
"investors invest in companies and the countries are
the platform of the companies. Therefore, an understanding of global

The more competitive a country is, the higher its wages can be justified.
There is a clear relation between the two variables. Countries below the regression curve have a strong competiveness rank relative to their labour costs while countries above the curve have a lower competiveness rank relative to their labour costs.
