The missing effect of investments of firms in information and communication technologies on productivity is studied by various recent papers (e.g. Oliner and Sichels 1994, Landauer 1995, Brynjolfsson and Hitt 1996). Several explanations are given for this missing link. Our paper deals with two...

This paper analyses the link between the high-skilled employment share and the level of investment in information technology (IT) in the service production process. The analysis is based on an unbalanced panel data set for 933 West German firms over the period 1994-1996. To account for firms...

Firm heterogeneity explains the productivity driven selection mechanism that determines aggregate productivity growth within industries. This paper empirically demonstrates that ICT has a robust impact on firm heterogeneity only when ICT is used intensively and jointly with specific ICT...

The paper provides empirical evidence for the question whether firms' ITenabled labour productivity is affected by the age structure of the workforce. We apply a production function approach with heterogenous labour to firmlevel data from German manufacturing and services industries. We find...

This paper empirically analyzes the relationship between firm-provided IT training and the firm's proportion of older workers. Using data from the ZEW ICT survey of the years 2004 and 2007, the results show that a firm's IT intensity plays a crucial role: firms intensively using information...

The paper analyses the relationship between two major challenges firms are faced to: using the potentials of information technologies (IT) as an enabler of process innovations on the one hand and an ageing workforce that might interfere these potentials on the other hand. Econometric results...

Two main hypotheses can be found in literature on why elderly workers have a lower probability of using information technology than their younger peers: lower learning capabilities and reduced incentives to invest in human capital. I use law changes in the unemployment compensation system...

This paper investigates to what extent the usage of information and communication technology (ICT) fosters innovation activities by facilitating more flexible organisational structures in firms. We distinguish between functional flexibility (the ability of workers to co-operate and take...
