A recently published report about the future skill needs for 27 European countries presents medium-term forecasts for skills in the European economic bloc as a whole and in each individual country within the bloc for 2015 (CEDEFOP, 2008). Where forecasting models have been evaluated, results show that forecasts can provide useful indications on overall labour market trends, but at the level of specific occupations projections are often unreliable (Neugart and Schomann, 2002; Sexton, 2002; Barnow, 2002; Richardson and Tan, 2007). Many employers find it hard to predict their future requirement for recruits. Empirical evidence shows that students also find it hard to predict which kinds of jobs are going to be in demand in the future (Borghans, Grip, and Heijke, 1996). In these areas forecasts of demand are linked to relatively stable demographic trends, and the state is often the dominant employer. Even in these areas, increasingly, international migration complicates the relation between national training efforts and labour supply.
