“…Absolute and relative wage levels are, however, subject to a variety of organisation‐specific influences, examples of which include custom and practice, formal negotiations, perceptions of what is ‘fair’ and a concern on the part of managers with developing and maintaining orderly pay structures (Brown and Nolan, 1988; Gilman et al ., 2002; Rubery, 1997). Studies have suggested that age‐related pay differentials might be eschewed because employers think it ‘fair’ to pay the ‘rate for the job’, or because wage offers are based on the experience and qualifications of recruits, irrespective of their age, or because of a concern that paying a lower rate might damage employee motivation or result in recruitment or turnover problems (Heyes and Gray, 2004; IDS, 2002; Norris et al ., 2003). In a similar vein, studies have found that few US employers paid young workers a sub‐minimum wage between 1990 and 1993 when the opportunity to do so was available to them (from 1990 until 1993) (Card and Krueger, 1995).…”
