THE INTELLECTUAL STRUCTURE OF SUPPLY CHAIN MANAGEMENT: A BIBLIOMETRIC APPROACH

Now that supply chain management has a two‐decade research history, it is possible to examine the literature to identify whether there is any latent intellectual structure using bibliometric tools. The study applies a citation and co‐citation approach to reveal four clusters of research that have emerged. One cluster has strong ties to the logistics field, with primarily conceptual articles. A second cluster finds its roots in operations research, and consists mainly of modeling articles. The application of multidimensional scaling, cluster analysis, and factor analysis on co‐citations demonstrated a clearly identifiable structure. The structure is examined and implications for the future development of supply chain research are discussed.     

The cost of labor adjustment: Inferences from the gap

This paper studies the aggregate implications of micro-level labor adjustment costs. Caballero and Engel [Caballero, R., Engel, E., 1993. Microeconomic adjustment hazards and aggregate dynamics. Quarterly Journal of Economics 108, 313–358] find a dependence of aggregate employment growth on the cross sectional distribution of “employment gaps.” This paper uses those results as moments in an indirect inference procedure to infer the underlying labor adjustment costs. We specify a dynamic optimization problem at the plant level, allowing for both convex and non-convex adjustment costs. Consistent with evidence at the micro level, our findings indicate that non-convex adjustment costs are necessary to match these aggregate moments.     

Strategies of effective low share businesses

Previous research has suggested that low share market businesses have dismal prospects. This study examines low share businesses which are effective. In particular, it examines the product-market choices and competitive strategies of effective low share businesses, comparing them with two control groups: effective high share and ineffective low share businesses. Data are drawn from PIMS data bases and hypotheses are tested using cluster analysis and discriminant analysis. Effective low share businesses are found to locate in stable rather than protected environments. Their competitive strategies are strongly characterized by selective focus on specific strengths.     

Changing employee values: deepening discontent?

This article presents a synthesis of data on employee attitudes gathered over the last 25 years. Most of the findings confirm the hypothesis that employees are discontented and expect more from their jobs now than they have in the past. While managerial satisfaction has remained relatively constant, the work satisfaction among hourly and clerical employees has sharply decreased. The authors attribute dissatisfaction to changes in the expectations and values of employees and warn that the deterioration of work attitudes may result in increased operating costs due to poor quality work, reduced output, absenteeism, etc. Instituting an employer attitude survey is suggested as a means of improving communication between management and employees and increasing job satisfaction.
