There is no official pension scheme based on capital
investment (even though the government is trying currently
to establish a private solution for the pensions – according
to the statistics – a major crisis is predicted in 2020
for the public system of pensions).
Pensions are made by 2 elements:
A) Basic plan (State plan)
B) Additional funds (pension funds in some countries, pension by compensation)
The right to pension is calculated according to the social security paiements
throughout your work duration. In France part of your salary is paid to
URSSAF (http://www.urssaf.fr/)
which uses the money to pay the current pensions and give you the right to obtain
a pension for yourself at retirement.
When you work in the European Union and you pay social
security, the Communautary Law applies and you get your right to the basic pension
plan A) continiously wherever you work. For additional pension funds B), the
equivalent is different in the coutries. In United Kingdom for example, it will
be the Pension Fund (private contribution) and in France a Pension
by Compensation. There is no automatic transfer with the State
pension plan A).
