Redefining the field of European human resource management: A battle between national mindsets and forces of business transition?

This article examines the conflict between cultural heritage and the current forces of global competition in Europe. The nature of management in European organizations is in a state of transition, influenced by competing forces of economic, social, and political integration or disintegration. A review of European research is used to question the idealistic picture of the Single European Market as a unifying force that will simplify international human resource management in multinationals. Taking a comparative rather than international human resource management perspective, the paper identifies the factors that have created national patterns of HRM within Europe. A dynamic and comparative ‘force field framework’ of HRM is developed in order to understand the managerial frames of reference that are currently guiding the field. © 1997 John Wiley & Sons, Inc.     

A continuous model for supply planning of assembly systems with stochastic component procurement times

This paper studies a customized product assembly scenario where some components cannot be stocked due to high component cost and risk. We consider the case where these key components are ordered after a demand has been registered with a promised delivery date. Component lead-times are stochastic and associated distribution function is known in advance. The objective is to determine the ordering time for each component such as to minimize the sum of expected holding and backlogging costs. An approach to solve this problem is proposed and the algorithm is tested on a randomly generated data set.     

Do Entrepreneurial SMEs Perform Better Because They are More Responsible?

Many scholars have investigated the direct impact of entrepreneurial orientation (EO) on performance, but this direct association seems both spurious and ambiguous because many parameters may have an indirect influence on this relationship. The present study thus considers sustainable practices—environmental practices, social practices in the workplace (SPW), and social practices in the community (SPC)—as three probable mediators in the relationship between EO and performance, which is considered in terms of its financial and non-financial dimensions. We seek to show to what extent small- and medium-sized enterprises’ (SMEs) sustainable practices are useful assets, which are supported by EO, to improve performance. Using a structural equation modeling approach, data collected from 406 French SMEs were tested against the model. Our findings reveal that EO has a positive impact on the implementation of sustainable practices and that SPW partially mediate the link between EO and performance. Taken together, these findings suggest that EO plays a role in indirectly promoting performance by enhancing certain human resource management practices.     

Exact confidence sets and goodness-of-fit methods for stable distributions

Usual inference methods for stable distributions are typically based on limit distributions. But asymptotic approximations can easily be unreliable in such cases, for standard regularity conditions may not apply or may hold only weakly. This paper proposes finite-sample tests and confidence sets for tail thickness and asymmetry parameters (α$\alpha$ and β$\beta$) of stable distributions. The confidence sets are built by inverting exact goodness-of-fit tests for hypotheses which assign specific values to these parameters. We propose extensions of the Kolmogorov–Smirnov, Shapiro–Wilk and Filliben criteria, as well as the quantile-based statistics proposed by McCulloch (1986) in order to better capture tail behavior. The suggested criteria compare empirical goodness-of-fit or quantile-based measures with their hypothesized values. Since the distributions involved are quite complex and non-standard, the relevant hypothetical measures are approximated by simulation, and p$p$-values are obtained using Monte Carlo (MC) test techniques. The properties of the proposed procedures are investigated by simulation. In contrast with conventional wisdom, we find reliable results with sample sizes as small as 25. The proposed methodology is applied to daily electricity price data in the US over the period 2001–2006. The results show clearly that heavy kurtosis and asymmetry are prevalent in these series.     

Proximity and Micro-Enterprise Manager’s Ethics: A French Empirical Study of Responsible Business Attitudes

This research article analyses the influence of micro-enterprise (ME) managers’ perception of their relationship to their environment on the nature of their ethics. We carried out a survey with the head managers of 125 French MEs, providing a large set of primary data. Two types of variables were defined: (1) variables related to the nature and intensity of the relationships between ME managers and their social environment, and (2) variables related to the ethical framework that the managers used. The results of univariate and bivariate analyses show significant statistical relationships between the variables that indicated perceived embeddedness in the community and ethical variables. This result underlines the idea that “communities of ethics” may have an important influence in MEs.     

Disability insurance and optimal income taxation

This paper studies the design of disability insurance scheme when agents differ in their privately known productivity. We extend the Diamond and Mirrlees (1978) two period model to allow for agents differing ex-ante in their productivity and characterize the optimal nonlinear tax transfer that maximizes a utilitarian welfare function when per-period earnings and age are observable while individuals’ productivity and health status are not observable. We show that the induced tax/benefit scheme should exhibit a marginal income tax that decreases with age for some agents. A marginal subsidy on the young high productive income may be desirable. While the disability scheme always involves the old low productive agents to be indifferent between working and claiming disability benefits, this result is not always true for the old high productive agents.

Index

We study two Durbin-Watson type tests for serial correlation of errors inregression models when observations are missing. We derive them by applying standard methods used in time series and linear models to deal with missing observations. The first test may be viewed as a regular Durbin-Watson test in the context of an extended model. We discuss appropriate adjustments that allow one to use all available bounds tables. We show that the test is locally most powerful invariant against the same alternative error distribution as the Durbin-Watson test. The second test is based on a modified Durbin-Watson statistic suggested by King (1981a) and is locally most powerful invariant against a first-order autoregressive process.     

The Relevance of XBRL Voluntary Disclosure for Stock Market Valuation: The Role of Corporate Governance

The aim of this paper is to investigate the relevance for stock market pricing of accounting earnings of voluntary disclosures in XBRL files considering the quality of corporate governance. Results are the following. It appears that XBRL extensions attract financial analysts. Good governance is positively associated with voluntary XBRL extensions. We observe that XBRL extensions enhance the positive relationship between accounting earnings and stock price. However, this positive association is reduced for firms with good governance, suggesting a substitution effect between XBRL extensions and corporate governance. Finally, it appears that XBRL extensions would strategically be related to earnings quality. This research highlights the importance to consider governance when assessing the value relevance of XBRL disclosures for stock market pricing.     

Time and the Price Impact of a Trade

We use Hasbrouck's (1991) vector autoregressive model for prices and trades to empirically test and assess the role played by the waiting time between consecutive transactions in the process of price formation. We find that as the time duration between transactions decreases, the price impact of trades, the speed of price adjustment to trade-related information, and the positive autocorrelation of signed trades all increase. This suggests that times when markets are most active are times when there is an increased presence of informed traders; we interpret such markets as having reduced liquidity.
