Among employed workers, under or over-qualification appears less common than in most OECD countries (Figure 2, Panel B; OECD and Statistics Canada, 2011; Randstad, 2012; in contrast, Quintini, 2011, suggests frequent under-qualification of workers), but many people occupy a position not directly related to their field of study, a common pattern across Eastern European countries (Figure 2, Panel C). Mobility of workers is essential to good matching. Although job-to-job mobility is about average, the reallocation of labour across economic sectors has slowed since the mid-1990s (Harasztosi, 2011) and geographic mobility is low', resulting in persistently large regional discrepancies in the unemployment rate (Figure 3).
