The Effect of Computer Use on Work Discretion and Work Intensity: Evidence from Europe

This article studies changes in computer use and work discretion and intensity in the EU-15 between 1995 and 2015. We document that while the proportion of workers using computers has increased from 40 per cent to more than 60 per cent, there remain significant differences between countries even within the same occupations. Several countries have seen a significant increase in computer use even in low-skilled occupations generally assumed to be less affected by technology. Overall, the great increase in computer use between 1995 and 2015 coincided with a period of modest deterioration of job quality in the EU-15 as a whole, as work discretion declined for most occupational and educational groups, while work intensity increased slightly for most of them. Our OLS results exploiting variation within country-occupation cells point to a sizeable positive effect of computer use on work discretion, but to no effect on work intensity. Our instrumental variable estimates point to an even more benign effect of computer use on job quality as measured by work discretion and work intensity. Hence, the results suggest that the (moderate) deterioration in the quality of work observed in the EU-15 between 1995 and 2015 has occurred despite the spread of computers, rather than because of them.     

The link between computer use and job satisfaction: The mediating role of job tasks and task discretion

This study focuses on the consequences of the use of computerized work equipment (hereafter: computer use) on the content and quality of work. It investigates, first, the relationship between computer use and both job tasks and task discretion and, second, their mediating role for the relationship between computer use and job satisfaction. With our German-UK comparison, we contribute to the long-standing debate on the upskilling/de-skilling nature of the use of technology and its repercussions on the quality of work. We analyse data from the Skills and Employment Surveys for the UK and the BIBB/BAuA Employment Surveys for Germany using structural equation modelling. In line with the literature on routine-biased technological change, we show that computers are complementary to the performance of less routine and more abstract cognitive tasks and that this relationship is conducive to a higher level of task discretion and job satisfaction in both countries. Accounting for differences in job tasks performed, we find a negative direct effect of computer use on both task discretion and job satisfaction in the United Kingdom but not in Germany. Our results indicate that the ultimate effect of computer use on both task discretion and job satisfaction depends on the institutional contexts in which technology is introduced.     

Communication and co-operation in product development: a case study of a European car producer

Continuous innovations in product and process technology, coupled with time-to-market pressure, have made rapid product development a key strategic objective of manufacturing firms. Consequently, many firms have started to define the ways in which products are designed, developed and produced, so as to reduce the time from conception to manufacture. The strategies employed to achieve this goal vary, and include the integration of functions through selective use of concurrent engineering, the formation of strategic project teams, and technological connections by CAD/CAM systems. The research reported in this paper, co-ordinated by the WZB Institute of Berlin, is aimed examining organizational, technological and human resources practices that enhance quality in R&D by improving communication and co-operation C&C) between the actors. Although the research was carried out in four countries(Germany, Italy, Japan and the USA) and in three sectors (car, personal computer and machine tools) this paper analyses the evidence provided by a set of face to face interviews of the managers, engineers and designers of a European car producer.

Problems and lessons of Japanese technology policy

Statistics on Japanese R & D reveal various problems of policy and implementation. Some difficulties of Japanese technological development and possibilities for overcoming them are discussed. Among others a fundamental problem is the generation of technology with less reliance on Western support. The relationship between the need for self-generated technology and the fact of excessive reliance on technology imports is discussed in regard to superiority, inferiority and appropriateness of Japanese technology. Innovation in the Japanese automobile and iron and steel industries is characterized as integrative or combinatory innovation associated with managerial innovation. The conditions under which integrative innovation is effective are identified, and these conditions are expected to be valid for many other sectors. Finally, the mechanism of government–industry cooperation in Japan is identified as an informational control system in contrast to the financial control system in Western countries, and the major medium of control by the Japanese government is identified as technological forecasting information.
These characteristics of Japanese technology management can be held up as valuable lessons for other countries given certain conditions which are expected to hold in many fields.     

Research on the interface factor in the development and utilization of new technology

AbstractThe interface factor in the development and utilization of new technology is analyzed with questionnaire surveys. The interface factor is found to determine R&D performance in a study of large manufacturing companies in the United States and in a study of computer utilization performance in commercial banks in the United States. A comparison of the interface factor in the functioning of R & D in the United States and Japan suggests that interface problems may be less serious in Japan. Company experience is reported which indicates that the interface function can be controlled by management policies, procedures and practices. The need for greater attention to the interface factor by executives and by researchers on R & D management is a conclusion which follows from the findings presented in this paper.

Permanent Jobs,Employment Protection,and Job Content

Using Programme for the International Assessment of Adult Competencies (PIAAC) data for twenty‐one countries, I study the impact of employment protection laws (EPL) on job content. I find that workers’ use of influence, reading, writing, planning, numeracy and information and computer technology skills, and their task discretion, were higher in permanent than in temporary jobs. Moreover, stricter EPL on permanent jobs raised the gap in job content for influence, reading, writing, and planning skills used in permanent jobs versus temporary jobs.

Task Polarization in the Japanese Labor Market: Evidence of a Long‐Term Trend

By quantifying the various skills required for different occupations, we examine the long‐term trend in labor‐market polarization in Japan in terms of tasks from 1960 to 2005. We find that the input share of nonroutine tasks has consistently and gradually increased, while that of routine tasks has decreased. With regard to nonroutine tasks, we observe an increase in the input shares of both high‐skilled analytical and interactive tasks and low‐skilled manual tasks. While we also find that the polarization depends on the introduction of technology, the progress of polarization is slower and smaller in Japan than in other countries.     

A quantitative assessment of innovation dynamics and R&D management in Japanese and West German telecommunications

Abstract
Among the industrial countries, different working divisions have evolved between manufacturing industry, governments and network operators, each being responsible for distinct parts of R&D in the telecommunications field. This paper provides a comparison of R&D in Japan and West Germany to several western industrial countries and highlights their diverse structures.
For this quantitative assessment various indicators for science and technology (S&T) have been compiled systematically. The new aspect of this paper is that indicators, only some of which are well established, can be interconnected provided that appropriate limitations are recognised. A comprehensive indicator system for research and development in telecommunications is currently not available as far as the author is aware. Consequently, subjective expert assessments are essential for the present indicator systems to overcome incomplete links between indicators, their poor adaptation to one another and data availability problems . The statistical sections here are therefore supplemented by a series of personal discussions in various countries.     

User benefits and operator costs of mobile number portability in Japan and impact on market competitiveness

This paper aims to review the process of mobile phone operators agreeing to introduce mobile number portability (MNP) in Japan. A study group formed by the Ministry of Internal Affairs and Communications estimated the proportion of MNP users and analyzed the user benefits and associated costs to introduce MNP. Owing to the particular market structure and technology available, MNP was expected to yield a larger benefit in the Japanese mobile market than that seen in other countries. Based on the results of the research reviewed with respect to the market situation one year after introducing MNP, the increased competition in the mobile phone market was onfirmed by decreasing call charges and a reduction in the share of the dominant operator.     

Attitudes of Design Students Toward Computer Usage in Design

The success of efforts to integrate technology with design education is largely affected by the attitudes of students toward technology. This paper presents the findings of a research on the attitudes of design students toward the use of computers in design and its correlates. Computer Aided Design (CAD) tools are the most widely used computer applications in design. An instrument was developed and applied for the first time to relate computer attitude to design field through CAD. Interior architecture undergraduates of Bilkent University participated in the survey. As a result, students’ attitudes toward the use of computers in design were found to be positive. A significant gender difference in attitudes toward computers was observed with males having more positive attitudes than females. The results also revealed that students’ attitude toward computer usage in design was highly related to their general attitude toward computers, but it was not correlated with their perception of instructors’ attitude toward the use of computers in design.     

Precursors of intellectual property rights enforcement in East and Southeast Asia

In this study we identify the main determinants of perceived strength of intellectual property rights in four developed (Japan, Singapore, South Korea, and Taiwan) and five emerging (China, Indonesia, Malaysia, the Philippines, and Thailand) Asian countries over the period 2003–2016. We use a panel model with additive unobserved individual-specific heterogeneity in a high-dimensional setting. The setting allows the number of time-varying regressors to exceed the sample size. Based on the Cluster–Lasso approach, we found that (1) bribery and corruption (inverse), equal opportunity, administration of justice, knowledge transfer, personal security and private property rights, and qualified engineers are significant determinants of intellectual property rights for developed countries; (2) adaptability of government policy, bribery and corruption (inverse), bureaucracy (inverse), and science in schools are significant determinants of intellectual property rights for emerging countries. Policy makers may use these results to strengthen IP rights and thus encourage indigenous innovation as well as foreign direct investment.     

融入技术附加值的国际竞争力评价方法——基于电子通讯设备产业的实证分析

鉴于即使属于同一个产业,产业内各贸易品的技术附加值也有显著不同,本文认为单纯使用以贸易规模为基础的评价指标,会高估以偏低技术含量产品为主的特定国家某产业国际竞争力,并低估以高技术含量产品为主的特定国家某产业国际竞争力。因此,本文引入显示性技术附加值(RTV)方法,以电子通讯设备产业为例,对其下属各类贸易品赋权,并据此计算包括中国在内的六个国家和地区的产业技术高度水平(TL),发现中国该产业的国际竞争力并没有贸易规模类指标所显示的那么理想,且产业内长期处于进口高技术含量产品、出口低技术含量产品的"技术逆差"状态,国际竞争力仍与美日等国存在较大差距。本文提出,以进出口规模为基础的经典指标是在评价产业国际竞争力的"量",而融入了技术附加值的创新性指标是在评价产业国际竞争力的"质",后者能比前者更加精准地衡量真实的产业国际竞争力水平。     

Assessment of information and communications technology maturity level

The use of information and communications technology (ICT) turned out to be a key factor in the process of the wider development of a country. It is therefore very useful to estimate ICT evolution by the means of an appropriate metric. Based on statistical data from 159 countries, the ICT maturity level index (IMLI) is proposed and estimated by using structural equation modelling (SEM). This index is a metric measuring the information society in a country and consists of three sub-indices which are access, use and skills. It is an improvement of the ICT development index, proposed by the ITU in 2009. The analysis divides the countries into two groups, the developed and the developing, due to major disparities in their statistical data. The criterion used to define the groups was the income, as expressed by the Gross National Income per capita. The impact of a number of influential parameters on the ICT maturity level is evaluated and it becomes obvious that there is a substantial difference in their impact between developed and developing countries. Finally, a procedure that allows the ranking of the countries, based on IMLI, is presented.

Restructuring Managerial Labour in the USA,the UK and Japan: Challenging the Salience of ‘Varieties of Capitalism’

This article provides a cross‐national, qualitative investigation into the experiences of middle managers in large organizations in the USA, the UK and Japan, following organizational restructuring. Despite well‐documented national differences in administrative heritage, institutional regimes or ‘varieties of capitalism’, our data point towards considerable similitude across the three countries in terms of a general expression of the need for change, and the concrete impacts of organizational reforms on managerial work. Specifically we analyse the changing nature of work roles, career paths, working hours and spans of control of mid‐level managers in five large firms in each of the three countries. The data demonstrate that middle managers in all three countries face fundamental changes to key areas of their work experience. In Japan, although changes do not amount to a genuine shift towards ‘Anglo‐Saxon’ institutions or business practices, the robust use of organizational reforms with very similar aims and underpinning assumptions to those used in the USA and the UK entails similar impacts in terms of work processes of middle managers across the three nations. This shared experience involved the augmentation of middle management skill levels, responsibilities and span of control, but alongside the downgrading of career expectations, and increased workload and work intensity. We argue that these changes are in keeping with some, but not all, of the features explained and predicted in Bravermanian labour process theory.
