CPB Netherlands Bureau for Economic Policy Analysis (CPB) was founded in 1945. Research at CPB is carried out on CPB’s own initiative, or at the request of the government, parliament, individual members of parliament, national trade unions or employers' federations. CPB is an integral part of the budget of the Ministry of Economic Affairs and Climate Policy. It is largely publicly financed. To ensure its independence, a maximum of twenty percent of its annual budget may originate from external assignments. However, CPB is not allowed to compete with commercial research bureaus, and external assignments are limited to local and national governments, European institutions or international governmental organisations.
