Unlocking the potential of advanced manufacturing technologies

This research examines whether investments in advanced manufacturing technologies (AMTs) such as flexible manufacturing systems (FMS), computer aided design (CAD), computer aided manufacturing (CAM), robotics, etc., are more likely to lead to improved performance if they are supported by improvements in the manufacturing infrastructure of the company. This question is evaluated using data gathered from 202 manufacturing plants chosen from industries generally considered to have relatively high investments in technology.Multiple item scales are developed and adapted from sources in the literature to measure investments in technology, infrastructure, and the performance of the plant. Evidence supporting the reliability and validity of these scales is provided. Hierarchical regression is used to analyze the relationship between technology, infrastructure, and performance. The results suggest that there is an important interaction between the adoption of advanced manufacturing technologies and investments in infrastructure. Firms that invest in both AMTs and infrastructure perform better than firms which only invest in one or the other. Separate analyses on sub-samples of firms with the highest and lowest investments in AMTs show that infrastructural investments have a stronger relationship with performance in the high investment group. Thus, the data indicate that infrastructural investments provide a key to unlocking the potential of advanced manufacturing technologies.

Dynamics of fertility and labour force participation of Canadian women in 1971 and 1981: a cohort approach

The authors analyze the relationship between labor force participation and fertility in Canada using data from the Public Use Sample Tapes from the 1971 and 1981 censuses. Factors considered include age, religion, educational status, and marital status. The authors conclude that "labour force participation of women seems to have less influence on fertility compared to [the] fertility effect on labour force participation."     

The accuracy of OECD forecasts

This paper examines the accuracy and properties of forecasts by the OECD for 24 countries and 8 variables. First the forecasts made in December of yeart?1 for yeart are examined, with the largest errors being for investment, industrial production and foreign balance. Next the way forecasts are revised between December and July is considered. Systematic revisions occur for Iceland, Turkey and Luxembourg. Finally the accuracy of forecasts made before, during and after the 1979 oil price rises are compared, and no evidence of a worsening of accuracy is found.     

Product quality: Impact of interdepartmental interactions

The authors examine the role of organizational factors affecting interdepartmental interactions and their subsequent effects on product quality. Results from a national study suggest that product quality is affected by interdepartmental conflict and connectedness. Importantly, the linkage between interdepartmental conflict and product quality appears to be robust across varying levels of market turbulence and technological turbulence. In contrast, interdepartmental connectedness appears to be more important for product quality under conditions of high market and technological turbulence. The results also indicate that interdepartmental interactions are influenced by leadership characteristics (risk aversion of top managers), reward system orientation, and organization structure (centralization, departmentalization, and hierarchical levels). Managerial implications and directions for future work are proposed. His research interests focus on marketing strategy, marketing management, and new product management.

Globalization, marketing resources, and performance: Evidence from China

Two important areas are underexplored in the relationship between marketing resources and performance. First, the subject has been primarily investigated in the context of Western countries, and inadequate attention has been given to emerging economies. Second, despite the recent growth in globalization, the moderating role of globalization on the link between marketing resources and performance has not been investigated. Addressing these important gaps, this article focuses on an emerging economy (China) and explores the moderating effect of globalization on this link. Specifically, the authors develop several hypotheses highlighting the moderating role of globalization activities (global product sourcing, global market seeking, and global partnership) on the link between marketing resources (market orientation, entrepreneurial orientation, and innovative capability) and firm performance. The findings of the moderating role of globalization provide several important implications for marketing theory development and managerial practice.
