The Incidence of Pension Contributions
In contrast to the standard demand and supply model of labor we find that average contribution rates matter more for incidence than marginal rates. Moreover, we find that a substantial part of the burden (some 70%) is borne by employers. This is in line with the statutory contribution rates (on average 70-30 for employers and employees) but could also be explained by other factors such as non-salience or bargaining. Together our findings indicate that incidence is best explained by a bargaining model of wages, at least in the short and medium term considered in our analysis.
