R&D personnel and human resource management in multinational companies: between homogenization and differentiation

This paper discusses the impact of globalization processes on models of R&D personnel management in multinational companies operating in Europe. Existing literature focuses on the globalization of R&D activity, on the one hand, and on national systems of innovation, on the other. By contrast, there are few studies of the linkage between the globalization of R&D and its impact on HRM. Drawing on the practices of multinationals in four sectors (pharmaceuticals, chemicals, computer hardware and software), the paper examines whether the hold of national differences in the area of HRM has been significantly weakened in the face of new models of competitiveness and management in multinationals. It focuses on two dimensions: recruitment and mobility. The studies highlight two major trends. The ‘internationalization’ of R&D clearly has effects on HRM models but not as great as might be expected. HRM policies such as recruitment and pay systems continue to be nationally based, reflecting legal and institutional differences. At the same time, in conjunction with new forms of R&D organization such as projects, the standardization of HRM tools may be observed. But this is partial and affects only a limited number of tools, notably individual evaluation.     

Crisis management in information system projects: lessons of a case study

This case study is reflective of the action‐research perspective documents applied in an intervention to manage a crisis during an information technology development project. The aim was to better understand how tools used to solve unstructured problems might help resolve such crises. The development and implementation of an intervention utilizing multiple tools is described. As a result of the intervention, a shared meaning of the crisis emerged among the major stakeholders along with a consensus as to appropriate solutions and action steps. Work on the project resumed to the satisfaction of management. Recommendations for future research are offered. Copyright © 2010 ASAC. Published by John Wiley & Sons, Ltd.     

Multivariate residual‐based finite‐sample tests for serial dependence and ARCH effects with applications to asset pricing models

In this paper, we propose several finite‐sample specification tests for multivariate linear regressions (MLR). We focus on tests for serial dependence and ARCH effects with possibly non‐Gaussian errors. The tests are based on properly standardized multivariate residuals to ensure invariance to error covariances. The procedures proposed provide: (i) exact variants of standard multivariate portmanteau tests for serial correlation as well as ARCH effects, and (ii) exact versions of the diagnostics presented by Shanken ( 1990 ) which are based on combining univariate specification tests. Specifically, we combine tests across equations using a Monte Carlo (MC) test method so that Bonferroni‐type bounds can be avoided. The procedures considered are evaluated in a simulation experiment: the latter shows that standard asymptotic procedures suffer from serious size problems, while the MC tests suggested display excellent size and power properties, even when the sample size is small relative to the number of equations, with normal or Student‐t errors. The tests proposed are applied to the Fama–French three‐factor model. Our findings suggest that the i.i.d. error assumption provides an acceptable working framework once we allow for non‐Gaussian errors within 5‐year sub‐periods, whereas temporal instabilities clearly plague the full‐sample dataset.

Generalized time-invariant overtaking

We present a new version of the overtaking criterion, which we call generalized time-invariant overtaking. The generalized time-invariant overtaking criterion (on the space of infinite utility streams) is defined by extending proliferating sequences of complete and transitive binary relations defined on finite dimensional spaces. The paper presents a general approach that can be specialized to at least two, extensively researched examples, the utilitarian and the leximin orderings on a finite dimensional Euclidean space.     

Stochastic Orderings of Convex-Type for Discrete Bivariate Risks

New classes of order relations for discrete bivariate random vectors are introduced that essentially compare the expectations of real functions of convex-type of the random vectors. For the actuarial context, attention is focused on the so-called increasing convex orderings between discrete bivariate risks. First, various characterizations and properties of these orderings are derived. Then, they are used for comparing two similar portfolios with dependent risks and for constructing bounds on several multilife insurance premiums.     

Accuracy Versus Falsification Costs: The Optimal Amount of Evidence under Different Procedures

An arbiter can decide a case on the basis of his priors or hecan ask for further evidence from the two parties to the conflict.The parties may misrepresent evidence in their favor at a cost.The arbiter is concerned about accuracy and low procedural costs.When both parties testify, each of them distorts the evidenceless than when they testify alone. When the fixed cost of testifyingis low, the arbiter hears both, for intermediate values one,and for high values no party at all. The arbiter's ability toremain uninformed as well as sequential testifying makes itmore likely that the arbiter requires evidence. (JEL D82, K41,K42)     

The firm,the platform and the customer: A “double mangle” interpretation of social media for innovation

The aim of this article was to explore the relationship between human actors and technology in the context of a social media platform, developed by a leading Italian firm in the food industry, and created to keep in contact with its customers, while gathering innovative ideas from them.In order to address these issues, we adopt a theoretical approach that is deeply rooted in Pickering's “mangle” theory, and Jones' subsequent metaphor of “double dance of agency” i.e. human and material agencies. A longitudinal case study has been developed with two rounds of interviews with marketing and R&D managers. A total of 8 recorded interviews, for 22 h overall.We examined conditions in the ongoing functioning of the platform, and considered how the website's dynamic materiality configures and reconfigures the practices and possibilities of different modes of engagement by multiple users (i.e. firm employees and customers) and vice versa. Specifically, dealing with the case of a social media platform developed by a firm to gain clearly defined organizational ends, the entanglement is considered to be double. One entanglement is between the human agency of customers and the material agency of the social media platform. The other is between the human agency of the firm and the material agency of the social media platform, including all actions that human agents (i.e. firm employees) undertake in seeking to channel material agency and shape actions of other human agents, i.e. customers.     

Budgetary governance and accountability in public sector organisations: An institutional and critical realism approach

This paper analyses the impact of the institutionalisation of governance and budgetary policies on the accountability of organisational actors from an institutional and critical realism perspective. The study extends the framework by Burns and Scapens (2000) to critical realism. Findings from field studies conducted in two public hospital districts in Finland show two institutions of budgetary governance: the political and the technical. Accountability practices depend on how the institutionalised policies have reduced or increased the gaps between the real, the actual and the empirical domains of reality of the organisational actors involved and the governance policy that prevails at a given domain of reality. The use of budgetary information as a tool of governance and accountability in the empirical field of the study cannot be taken for granted.
