The short answer is no. I'm not aware of the Danish reforms in detail. All I do know is that Denmark, unlike many other European countries, has avoided the use of payroll taxes to fund all social security and health and other expenditures. What people have found is that actually the Danish labour market is much more flexible compared to other European countries, and part of that is attributed to the payroll tax, but I think maybe some of these other factors are playing a hand as well.
