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...

In this paper, it is argued that ICT investment is closely linked with complementary innovations and most productive in firms with innovative experience. In an analysis based on firm?level panel data covering the period 1994?99, system GMM estimates for an extended production function framework...

In order to assess the productivity effects of information and communication technologies (ICT), regressions based on cross?sectional firm?level data may yield unreliable results for the commonly employed production function framework. In this paper, various estimation biases and econometric...

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 examines the relationship between the use of advanced technologies such as ICT, and outcomes such as productivity, the skill mix of the workforce and wages using micro data for the U.S. and Germany. We find support to the idea that U.S. businesses engage in experimentation in a...

From a macroeconomic perspective the term "new economy" describes a phenomenon of persistent strong and low-inflation growth due to the large diffusion of information and communication technologies (ICT). This paper looks into Europe's position with respect to the new-economy phenomenon. Section...

Seit der zweiten Hälfte der neunziger Jahre setzt sich mehr und mehr die These durch, dass mit den neuen Informations- und Kommunikationstechnologien ein neues „goldenes" Zeitalter mit höheren Produktivitäts- und Wachstumsraten angebrochen sei. Worauf beruht der so genannte Neue...

Small and medium enterprises are an important factor in the East African economies especially with respect to employment. The increasing competition through globalisation puts them under considerable pressure. Through the rapid spread of information and communication technologies (ICT) and ever...

Using a country-industry panel dataset (EUKLEMS) we uncover a robust empirical regularity, namely that high-risk innovative sectors are relatively smaller in countries with strict employment protection legislation (EPL). To understand the mechanism, we develop a two-sector matching model where...
