A sectoral model of the Norwegian economy
The demand for labour by education
To what extent do relative wage differences affect enterprises’ demand for labour with different educational background? A relative wage increase for low skilled labour will result in enterprises’ rather choosing medium skilled labour, and vice versa.
Since the 1970s, relative wages have remained fairly stable in Norway, and the structure of wages can be regarded as relatively compressed. This means that wages are relatively low for workers with high skills whereas wages for low skilled workers are high, by international comparison. This makes it more attractive for a person seeking employment to come to Norway if he or she is low skilled. After the enlargement of the EU/EEA in 2004, the number of migrant workers to Norway has increased sharply. It is therefore of particular interest to examine the factors that determine the enterprises' demand for labour by education, in particular the importance of relative wages.
This report studies the factors that determine the demand for workers with different skills. In particular, we investigate to what extent relative wage differences may explain the large increase in the demand for highly educated labour in the longer term. Earlier modelling of demand for labour in Norway has in large part distin-guished between workers with high and low education. In this report, we divide the workforce into three different groups according to the level of education. Persons with primary and secondary general education are considered as low skilled, while those with higher education at university or college level are considered as high skilled. Persons with secondary vocational education do not formally have longer education than those with secondary general education, but they have acquired technical skills, and are possibly more skilled than persons with secondary general education in working life. This labour category is therefore considered to be me-dium skilled.
In this report we examine the price sensitivity of demand for labour with different education and the substitution possibilities between education groups. The analysis is based on data from 1972-2007 and includes 13 industries in the Norwegian mar-ket activities. Our results indicate by and large greater price sensitivity in demand for labour with low skills. A wage increase will thus lead to a greater decline in demand for low skilled labour than for those with medium and high skills. Fur-thermore, we find that the various educational groups are substitutes in most indus-tries and that the substitution possibilities are generally greater between low and medium skilled labour. The effects are considerable in some labour intensive in-dustries, indicating that higher relative wages for low skilled are likely to result in a shift in demand towards medium skilled labour at the expense of low skilled la-bour. We also find support for the theory that technological progress increases demand for high skilled labour and reduces the need for low skilled labour.
