Comment on “Revealing Differences in Willingness to Pay Due to the Dimensionality of Stated Choice Designs: An Initial Assessment”

There are very few studies that quantify the interactions and tradeoffs between statistical and cognitive efficiency in designing stated-choice studies. While a conceptual framework for evaluating cognitive strategies would be desirable, Hensher adopts a strictly empirical approach in this experiment. The success of the study must be evaluated in light of his aggregating attributes rather than controlling the number of attributes, asymmetry in the narrow-range and wide-range attributes, and lack of orthogonality between the number of attributes and number of alternatives. Nevertheless, Hensher challenges uncritical acceptance of any given set of design features and correctly insists that we confirm our experience with rigorous, quantitative experiments.     

Parallel Neutrality

This paper develops the notion of parallel-neutral technical change for inputs and outputs. It is shown that parallel-neutral technical change generalizes existing radial notions of neutral technical change. A taxonomy of the structural consequences of parallel-neutral technical change is developed.     

A cybernetic model of work-life balance through time

Answering a call for a more fully developed concept of work-life balance (WLB), we use person-environment fit and control theories to develop a model of WLB incorporating the work, family, and personal domains. We propose a cybernetic model which recognizes that individuals have a desired balance among the three domains that serves as a standard against which they compare their perceptions of WLB at any given point in time. Our cybernetic model suggests that individuals will seek to restore balance when a negative imbalance is perceived. Further we propose that role senders and resources in the domains, as well as anticipated future WLB and retrospective perceptions of WLB also affect desired balance and actions. We discuss the implications of the proposed model for future research and practice.     

The economics of markets and platforms

Advances in the study of both markets and platforms contribute to economics. Platforms are typically digital markets, although platforms can designate markets generally. So, the economics of markets and the economics of platforms are one and the same. Platforms show the critical role of intermediaries in endogenous price adjustment and market clearing. The platform model remedies problems with general equilibrium analysis by combining and extending the basic Walrasian and Marshalian market models. The analysis of platforms provides explanations for the bid–ask spread, including market power, search costs, matching costs, adverse selection, and moral hazard. The study of platforms demonstrates the importance of participation and coordination in the formation of markets. The discussion emphasizes that platforms have significant implications for the theory of the firm. The analysis further considers how platforms affect innovation and entrepreneurship.     

HRM in dynamic environments: Exploitative,exploratory, and ambidextrous HR architectures

Abstract

The current economic crisis has brought to the fore the need for firms to deal with ambiguity and complexity. Hence, firms need a specific balance between exploration and exploitation in order to keep pace with varying and changing environmental conditions. Hitherto, there is limited research that has examined the nexus of HR architectures, ambidexterity, and environmental dynamics. In this conceptual paper we ask: How do HR architectures serve as a means of balancing exploitative and exploratory learning in different dynamic environments? We explain how exploratory, exploitative, and ambidextrous HR architectures with their embedded HRM systems on the business unit level enable organizations to meet different environmental requirements. Thus, firms in which heterogeneous demands for flexibility and for innovation co-exist need to develop internally differentiated HR architectures. In particular, we elucidate how critical the organization’s ability is to connect different HRM systems to create an ambidextrous HR architecture to find an appropriate balance between exploration and exploitation.     

An empirical analysis of green supply chain management in the German automotive industry

The purpose of this paper is the empirical investigation of the status quo of green supply chain management in the German automotive industry from a practitioner's point of view. Several aspects of green supply chain management, such as the point of time of implementation, the driving forces, the relevance of intended goals and their particular realization and the adoption of eco‐programs with suppliers and customers as well as internal and external barriers are analyzed. Furthermore, the link to different performance criteria is tested by inductive statistics in order to show the potential of green supply chain management for competitiveness. For this study, managers from the automotive supply industry in Germany were asked about their estimations in this regard. The main conclusion is that managers express the need for green supply chain management on the one hand but also see corresponding problems in terms of required resources on the other hand. Furthermore, the analyses show that green supply chain management leads to higher performance in terms of several performance criteria.

Endogeneity and the relationship between board structure and firm performance: a simultaneous equation analysis for the Athens Stock Exchange

The main goal of this paper is to examine the relationship between the three most important characteristics of the board of directors with firm performance. More specifically, we investigate whether the independence of the board, the leadership structure and the board size, are exogenous determinants to the firm's performance, using a simultaneous equations framework. Our database is composed of firms quoted in the ASE, starting from 146 observations in 2000 and ending with 232 firms in 2006. The findings suggest that the board independence and the leadership structure do not affect the firm performance. On the other hand, an inverse relationship between board size and firm performance is observed. Copyright © 2010 John Wiley & Sons, Ltd.     

Supply management in American public administration: Towards an academic discipline?

This article examines the development of supply management in the U.S. to assess its progress towards academic disciplinary status. A comparison of the fields of business administration and public administration indicates that supply management is more developed in the former than in the latter, which inhibits its disciplinary status. Various reasons for this uneven development in the two fields are explored. The paper argues that a paradigm shift must occur for public supply management, which will re-orient it around the concept of the public interest. This will require public supply professionals to participate strategically in public policy-making in order to ascertain and promote the public interest. A policy framework is used to illustrate this re-orientation and to suggest directions for further research.
