However, in most cases, the revisions offset each other as regards their impact on the most aggregate indicators. For example, for the latest published year (2009 for France and Portugal, 2008 for all other countries), the revision to the value of the overall summary EPL indicator is greater than 0.2 points (that is less than 10% of the OECD average) in only ten countries (see the figure below) with a maximum revision of 0.32 points. Similar results emerge as regards the synthetic indicator of employment protection for regular workers, including additional provisions for collective dismissals (EPRC), and the synthetic indicator on regulation for temporary workers (EPT). This is reassuring as regards the empirical evidence, since only synthetic indicators are typically used in macro-econometric analyses (see Section 1), with the sole partial exception of Bassanini and Gamero (2013).
