The Impact of Office Machinery and Computer Capital on the Demand for Heterogeneous Labour

We study the impact of office and computing machinery (OCM) on the demands for workers with different educational levels. The empirical analysis relies on a system of demand equations that nests the translog, the generalised Leontief and the normalised quadratic specifications. Using panel data on 35 German industries, we find little evidence for a robust substitutability relationship between unskilled workers and OCM capital in manufacturing industries. In the non-manufacturing sector, however, we find some evidence for substitutability between OCM capital and unskilled workers.
