B2B or not to be : does B2B e-commerce increase labour productivity? by Irene Bertschek( Book )
8 editions published in 2004 in English and held by 13 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
Productivity effects of organizational change : microeconometric evidence by Irene Bertschek( Book )
5 editions published between 2000 and 2001 in English and German and held by 12 libraries worldwide
This paper analyzes the relationship between investment in information and communication technology (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: enhancement of group-work and the flattening of hierarchies. Empirical evidence is provided for a sample of 411 firms from the German business-related services sector. A simultaneous econometric model for labor productivity and firms 'decision to reorganize workplaces shows that changes in human resources practises do not significantly affect firms' output elasticities with respect to information and communication technology, non -ICT -capital and labor. We also do not find significant differences in firms' returns to scale. The point estimates of the individual output elasticities and of the control variables for observable firm heterogeneity are, however, generally larger if workplace reorganization is realized. We therefore apply Kernel density estimation technique to demonstrate that the entire labor productivity distribution shifts out to the right if workplace reorganization takes place, indicating that workplace reorganization induces an increase in labor productivity. Signifficant differences in the productivity of ICT -capital and non -ICT -capital cannot be found

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 10 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 9 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

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
More bits - more bucks? Measuring the impact of broadband internet on firm performance by Irene Bertschek( Book )
5 editions published between 2011 and 2013 in English and held by 5 libraries worldwide
Numerous empirical studies at different levels of aggregation demonstrate the important role of information and communication technologies (ICT) for economic performance. As general purpose technologies ICT enable firms to reshape their business processes and to improve their products and services. Firms' innovation activity in turn increases labour productivity thereby entailing growth and competitiveness. Policy makers and industry representatives denote the availability of an efficient broadband Internet infrastructure to be essential in order to reap the potential benefits of ICT. This paper provides empirical evidence on the causal impact of broadband Internet on firm performance using a sample of German manufacturing and services _rms. Firm performance is measured in terms of labour productivity and realised product and process innovation. 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. Thus, firms that used broadband Internet in the early phase of DSL expansion where more likely to reshape their business processes and to bring new or improved products and services to the market

Trade and technology: new evidence on the productivity sorting of firms by Irene Bertschek( Book )
3 editions published in 2013 in English and held by 2 libraries worldwide
Several studies document an important relationship between firms' productivity and their internationalisation strategy. Recent evidence suggests that trade liberalization might imply firm growth increasing firms' probability to invest in new technologies which in turn might result in higher productivity

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 )
3 editions published in 2013 in English and held by 2 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
