Using German firm-level data, an endogenous switching regression model within a production function framework is estimated in order to explore differences in labor productivity between IT outsourcing and non-IT outsourcing firms. This approach takes possible complementarities between IT...

This paper analyses the impact of business process outsourcing (BPO) on firm productivity based on a comprehensive German firm-level panel data set covering manufacturing and service industries. The growing importance of service inputs into the production process is undisputed. Firms...

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...

The paper provides empirical evidence for the causal impact of broadband Internet on the economic performance of German firms. Performance is measured in terms of labour productivity and realised process and product innovations. The analysis refers to the early phase of DSL expansion in Germany...
