Productivity effects of organizational change : microeconometric evidence by Irene Bertschek( Book )
6 editions published between 2000 and 2003 in English and German and held by 17 libraries worldwide
This paper analyzes the relationship between investment in information and communication technologies (ICT), non-ICT-investment, labor productivity and workplace reorganization. Firms are assumed to reorganize workplaces if the productivity gains arising from workplace reorganization exceed the associated reorganization costs. Two different types of organizational change are considered : introduction of group-work and flattening of hierarchies. Empirical evidence is provided for a sample of 411 firms from the German business-related services sector. We develop and estimate a model for labor productivity and firms' decision to re-organize workplaces that allows workplace reorganization to affect any parameter of the labor productivity equation. Our general and flexible methodology allows to properly take account of strategic complementarities between the input factors and workplace reorganization. The estimation results show that changes in human resources practices do not significantly affect firms' output elasticities with respect to information and communication technologies (ICT), non-ICT-capital and labor although most of the point estimates of the individual output elasticities and of the control variables for observable firm heterogeneity are larger if workplace reorganization is realized. We therefore apply Kernel density estimation technique and demonstrate that for firms with organizational change the entire labor productivity distribution shifts significantly out to the right if workplace reorganization takes place, indicating that workplace reorganization induces an increase in labor productivity that is attributable to complementarities between the various input factors and workplace reorganization. By contrast, firms without organizational change would not have realized significant productivity gains if they had reorganized workplaces

B2B or not to be: does B2B e-commerce increase labour productivity? by Irene Bertschek( Book )
9 editions published in 2004 in English and held by 14 libraries worldwide
We implement an endogeneous switching-regression model for labour productivity and firms' decision to use business-to-business (B2B)e-commerce. Our approach allows B2B usage to affect any parameter of the labour productivity equation and to properly take account of strategic complementarities between the input factors and B2B usage. Empirical evidence from 1,394 German firms shows that firms using B2B e-commerce have a significantly higher output elasticity with respect to ICT-investment and produce significantly more efficiently than firms that do not use B2B. Firms' labour productivity is enhanced by using B2B
The adoption of business-to-business e-commerce empirical evidence for German companies by Irene Bertschek( Book )
3 editions published in 2002 in English and held by 11 libraries worldwide
Although in its infancy, one promising application of Internet technology for firms is so-called Internet commerce or electronic commerce. This paper analyses the determinants of B2B (business-to-business) adoption borrowing from the literature on the adoption of new technologies and considering factors like firm size, corporate status, human capital and international competitive situation. An ordered probit model is applied to a data set containing about 3,000 enterprises from the German manufacturing industry and the German services sector in the year 2000. We find positive and significant effects of firm size, the share of highly qualified employees and the export share. An IT-intensive production process enhances the probability of a broad use of B2B e-commerce. An important influence on the use of B2B is the bandwagon effect, implying that firms are more likely to use this new Internet application if others within the same industry likewise do it. We find no significant effects of firm age and of the fact that a firm belongs to a group of companies as measures of a firm's flexibility and financial power
IT, organizational change and wages by Irene Bertschek( Book )
3 editions published in 2003 in English and held by 10 libraries worldwide
Recent studies emphasize the complementary relationship between information technology and organizational changes. We analyze the wage impact of computer usage at the workplace and of organizational changes in companies, taking possible complementarities into account. The analyses are based on individual-level data for West Germany in 1998-1999, including information about individual characteristics, workplace characteristics and company characteristics. We find positive wage markups for computer usage and organizational changes. Wage premiums for organizational changes exist across rather than within firms. We find no evidence for complementarities between computer use and organizational changes in terms of wages

Produktivität IT-basierter Dienstleistungen wie kann man sie messen und steuern? : Endbericht ( file )
3 editions published in 2014 in German and held by 9 libraries worldwide
Informations- und Kommunikationstechnologien haben die Produktion in Unternehmen grundlegend verändert. IT-basierte Dienstleistungen stellen ein zentrales Bindeglied zwischen vielen anderen Unternehmensprozessen dar und leisten einen wichtigen Beitrag zur betrieblichen und gesamtwirtschaftlichen Produktivität. Welche Konzepte gibt es zur Messung und Steuerung dieser Produktivität und wie werden sie in der Praxis eingesetzt? Wie können sie weiterentwickelt werden? Diese Fragen standen im Mittelpunkt des Forschungsprojektes "Produktivität IT-basierter Dienstleistungen", das das Zentrum für Europäische Wirtschaftsforschung (ZEW), Pierre Audoin Consultants GmbH (PAC) und die Universität Mannheim gemeinsam in den Jahren 2010 bis 2014 durchgeführt haben. Das Projekt wurde vom Bundesministerium für Bildung und Forschung (BMBF) im Rahmen des Programms "Innovationen mit Dienstleistungen" gefördert. Ziel des Projektes war es, die Messung, die Bestimmungsfaktoren und die Steuerung der Produktivität IT-basierter Dienstleistungen aus verschiedenen Blickwinkeln zu untersuchen. Diese Blickwinkel lassen sich anhand der Frage erläutern, welche gesellschaftlichen Akteure ein Interesse haben, Produktivität IT-basierter Dienstleistungen zu messen
Mobile and more productive? firm-level evidence on the productivity effects of mobile internet ; use at the early stage of diffusion by Irene Bertschek( Book )
7 editions published between 2013 and 2015 in English and held by 8 libraries worldwide
Mobile internet access allows for flexibility with respect to working time and working place. We analyse whether employees' use of mobile internet access improves firms' labour productivity. Our data set comprises 2460 German firms and refers to the year 2010, when mobile internet started its diffusion process to firms on a large scale. The econometric analysis shows that firms' labour productivity significantly increases with the share of employees with mobile internet access. However, an instrumental variable approach reveals that mobile internet use does not cause higher labour productivity

More bits - more bucks? Measuring the impact of broadband internet on firm performance by Irene Bertschek( Book )
6 editions published between 2011 and 2013 in English and held by 7 libraries worldwide
The paper provides empirical evidence for the causal impact of broadband Internet on firms' labour productivity and realised process and product innovations. The analysis refers to the early phase of DSL expansion in Germany from 2001 to 2003, when roughly 60 percent of the German firms already used broadband Internet. Identification relies on instrumental variable estimation taking advantage of information on the availability of DSL broadband at the postal code level. The results show that broadband Internet has no impact on firms' labour productivity, whereas it exhibits a positive and significant impact on their innovation activity. -- labour productivity ; product and process innovation ; broadband Internet

It is never too late for changes? analysing the relationship between process innovation, IT and older workers by Irene Bertschek( Book )
3 editions published in 2010 in English and held by 6 libraries worldwide
The key role of information technologies (IT) for productivity and growth is meanwhile undisputed. As so-called 'general purpose technologies' they enable product as well as process innovation which in turn may result in positive productivity effects and ensure firms' long-run competitiveness. While on the one hand IT offer firms huge potentials for reshaping business processes and for supporting their innovation activities, firms are on the other hand faced to an ageing workforce. The probability and frequency of IT and software use are not the same for all age groups. In 2008, 28 percent of the individuals from 55 to 64 years used a computer at their workplace, whereas more than 50 percent of the people in each of the age groups between 25 and 54 years did so. This might be partly due to older people working in occupations without IT adoption. However, the lower level of IT use by older workers is rather caused by their IT skills, as suggested by several empirical studies, finding that older workers have lower IT skills compared to younger workers and a lower level of mastery of equipment and software. This paper provides empirical evidence on the question whether firms' IT-enabled innovative activity is affected by the age structure of the workforce. We find that the probability of realising process innovations is positively related to the IT-intensity of the firms supporting the hypothesis of the innovation-enabling character of IT. However, the share of employees older than 49 is negatively and significantly related to firms' innovation activities. This is underpinned by a negative relationship between the interaction of this age group and the IT-intensity and process innovations. IT-specific training for older workers, by contrast, is conducive to the probability of process innovation. This result implies that not older workers in general impede firms' innovation capabilities, but older workers who lack the appropriate IT skills
