Abstract: Multivariate Tobit models are estimated using German cross sectional data to test whether strategic complementarities exist between expenditures in four different types of ICT-components. If two ICT-components are complements, they are correlated (provided that agents act rationally). Significant correlations between all four types of ICT-expenditures are found and can neither be removed by standard firm heterogeneity control variables such as firm size, firms workforce qualification structure nor by firms ICT-structure so that indication for the presence of complementarities is provided.
