“…Gregory and Elias (1994), for example, used longitudinal data collected from employers in the UK New Earnings Survey (NES) and found considerable mobility out of the bottom of the wage distribution, especially by younger workers. More recent studies, both in the United Kingdom and elsewhere in Europe, have further advanced our understanding of low-pay dynamics by employing statistical techniques that take into account the endogeneity of the initial wage state (Stewart & Swaffield, 1999;Cappellari, 2002;Sousa-Poza, 2004) and in, some cases, panel attrition as well (Uhlendorff, 2006;Cappellari & Jenkins, 2008a). In contrast to the earlier work based on the NES, these studies emphasised the evidence on persistence of low pay.…”
