Segmented labour market theory takes the view that the traditional neo-classical view of the working of the labour market is inadequate. It sees the labour market as fragmented into numerous non-competing groups – the markets for unskilled manual workers in the car industry and doctors, for example. The wages of unskilled manual car workers in the car industry are likely to respond to the forces of demand and supply (as outlined in Section 13.3), since the emergence of a wage differential is likely to encourage unskilled manual workers from other sectors. Such movement, however, is not possible into highly skilled occupations like medicine and engineering. Therefore there is not likely to be such a relationship between wage levels – the labour market is segmented.
