The instrument is permanent since 2012. The effectiveness is not directly measured. Pick-up by firms is evaluated in, for example, Efstathiou, Mathä, Veiga, Wintr (2017), BCDL Working Paper No 110. The instrument had an increasing acceptance by companies and was extended to cover qualified young job-seekers too. Given its positive development, the measure has been extended twice to then become a permanent measure.
