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...

Total employment in Germany is supposed to increase if people could realize their desired working hours. However, this back-of-the-envelope calculation overestimates the effect of loosening hours constraints, because even in a very flexible labor market there will exist hours restrictions for...

This paper analyses the relevance of information and communication technologies (ICT) for firms' probability of global sourcing of inputs. Using firm-level data from Germany in 2009, which include mainly small and medium-sized firms, the empirical analysis differentiates between manufacturing...

Our paper contributes to the discussion about Europe's digital sovereignty. We analyze the relationship between firm performance and the diversification of sourcing countries for imported ICT goods. The analysis is based on administrative data for 3888 German manufacturing firms that imported...

In this paper, I analyse the relationship between offshoring and ICT at the firm level differentiating between manufacturing and services. Using firm-level data from the manufacturing and service sector in Germany and a broad range of ICT measures, overall, the results reveal a positive...

Using a unique German firm-level data set, we provide empirical evidence for a productivity sorting along two dimensions: international activity and technology choice. We consider domestic and exporting firms and measure technology choice by firms' actual use of advanced information technology...

We investigate the extent to which complementarities between technical and business skills of founders and employees matter for the generation of market novelties by new ventures. Using data about German start-ups, we find that there are no complementarities between technical and business skills...
