Estimating impact of absenteeism 
=================================
Overall the full-time equivalent employment years due to absenteeism are used to determine annual, country-specific welfare 
payments.

For this, the following information is used:

 #. Information on percentage of compensated sick leave (:math:`PCSL`).
 #. Information on percentage of salary paid given paid sick leave (:math:`{PC}_{comp}`) :cite:p:`SocialSecurityAdministration2016`

In absence PCcomp, weekly compensated sick leave paid :cite:p:`SocialSecurityAdministration2016`. 

In presence of PCSL and PCcomp data, the welfare cost, WC, is calculated as follows: 

.. math:: 
   WC = {personyears}_{absent} \times PCSL \times {PC}_{comp} \times Wage 

Where wages are specific for each country, year, and gender.

In the absence of PCcomp data, the welfare cost WC is calculated as follows: 

.. math:: 
   WC = {personyears}_{absent} \times PCSL \times sickweeksalary \times 52

PCSL is assumed to equal 1, except for Austria (0.57), Denmark (0.93), and France (0.91). 

For future year salary, :math:`sickweeksalary` is not be adjusted for wage growth until 2050.
