Forecasting the labour market by occupation and education: Some key issues

In this paper, we focus on two key characteristics of ROA’s forecasting approach of the labour market by occupation and education. These concern the use of the gap approach, and the substitution of education programmes within occupations. We show that the gap between supply and demand constitutes a useful and informative concept, which can be justifiably used as long as too little is known about the adjustment process in the labour market. Then we discuss the structure of the substitution process, mainly focusing on substitution as a result of the initially expected gaps between supply and demand. We distinguish between active substitution, resulting from supply-demand mismatches for the education programme concerned, and passive substitution, which is due to spillover effects from supply-demand mismatches for other education programmes. Passive substitution between education programmes is included in the forecasts when the final gaps between supply and demand are calculated. Recent ROA forecasts are used to illustrate the meaning of the various substitution processes for expected labour demand and the gaps between supply and demand. We find that omitting substitution demand from the forecasting model results in future labour market prospects that are generally too pessimistic for the higher educated.
