Innovation spending and productivity growth in the German economy 1980–1986

Abstract

A newly developed technique involving vertically integrated input-output sectors is used to examine the relationship between labour productivity and innovation expenditures in the German economy during the period 1980 to 1986. The productivity measures used, dubbed Harrod-Robinson-Read (HRR), take into account the direct and indirect labour used in each consumption goods sector. Included in these measures is the labour content of new capital investment. The HRR measures show higher rates of productivity growth in most sectors, compared to the simple direct labour requirements measures. This is due to the fact that the HRR measures take into account the increased efficiency with which new capital is produced. The second part of the study examines the relationship between labour productivity and innovation expenditures as measured by the IFO (Institute for Economic Research – Munich) innovation survey. Using cross section data for 58 German industries, a strong correlation was found between direct labour pr...
