Pilot studies
Article 8
1. Whenever improved basic information is required for the compilation of the harmonised indices, or when the need for improved comparability of the harmonised indices is identified in the methods referred to in Article 4(4), the Commission (Eurostat) may launch pilot studies, to be carried out on a voluntary basis by Member States. 2. The general budget of the Union shall, where appropriate, contribute to the financing of such pilot studies. 3. The pilot studies shall assess the feasibility of obtaining improved basic information or adopting new methodological approaches. 4. The results of the pilot studies shall be evaluated by the Commission (Eurostat) in close cooperation with Member States and the main users of the harmonised indices, taking into account the benefits of having improved basic information or new methodological approaches relative to the additional costs of production of harmonised indices. 5. By 31 December 2020 and every five years thereafter, the Commission shall submit a report to the European Parliament and the Council evaluating, if applicable, the main findings of the pilot studies.
