The Institut des politiques publiques is today releasing an opensource test function for identifying the inefficiencies of a socio-fiscal system. This tool, developed by a European team including IPP researchers, can be used to identify the conditions under which reforms can be pareto-improved.

In this note, the researchers have applied the test function retrospectively to the 2019 prime d’activité reform, following the yellow vests movement.

They show that certain inefficiencies already existed before the 2019 reform: they are found around 23,000 and 28,000 euros gross annual salary. For the record, the reform of the prime d’activité increased the number of beneficiaries by 37%, as part of an overall plan worth 10 billion euros.
