COMPUTER USE AND STRUCTURAL CONTROL: A STUDY OF AUSTRALIAN ENTERPRISES

This article investigates underlying relationships between the extent of use of computers and dimensions of organization structure. Empirical tests on a sample of 149 Australian work-units show strong associations between computer use and structural characteristics. Specifically, greater computer use is found to be related to less centralization and greater formalization and departmentalization. Further tests show that these associations are to some extent moderated by size. However, this moderating effect is most apparent in small organizations for formalization and departmentalization while the relationships involving centralization are more prominent in larger work-units. Factor analysis led to the diagnosis of two major types of computer use (i.e., informational and operational use). Tests on these categorized effects and the factor-analysed structural dimensions revealed that: (1) the effects on centralization are more strongly explained by the impact of operational use on the ‘centralization of operational decisions’ sub-measure and that of informational use on ‘financial decisions’; (2) formalization and departmentalization are found to be most strongly influenced by greater informational use. Here again, significant relationships were found between sub-measures, the most important of which is the relationship involving the informational factor of formalization with the informational use of computers and the relationship between departmentalization of core functions and the operational use of computing technology.     

Corporate environmental commitment: Developing the operational concept

This article attempts to develop an operational measure of the notion of Corporate Environmental Commitment (CEC), through an examination of CEO's perceptions of their firms' behaviour regarding a number of environmental items. This is done by identifying a number of salient items in the literature and integrating them into a survey instrument. The mail survey was administered to the key informants of the 1000 largest organisations in Australia of which 306 responded. Iterative Factor-Analysis of the data revealed that the questionnaire items (55 items in total) could be statistically collapsed into four factors representing the overall degree of ‘Corporate Environmental Commitment’. The four factors were (1) the degree to which environmental audits are emphasised as an environmental evaluation tool (Audit); (2) the existence and role of a clear and well disseminated environmental policy (Policy); (3) consideration of environmental impacts in assessing future corporate activities including investments & projects (Future Activities) and (4) incorporation of environmental issues in corporate appraisal systems (Appraisal Systems). Internal consistency within each of the four factors revealed significant reliability of all factors. It is suggested that the use of the four-factor method uncovered in this study bears significant practical relevance, allowing firms to assess their environmental commitment (EC) at the corporate level.

Modelling conditional moments and correlation with the continuous hidden-threshold-skew-normal distribution

A key issue in modelling conditional densities of returns of financial assets is the time-variation of conditional volatility. The classic econometric approach models volatility of returns with the generalized autoregressive conditional heteroscedasticity (GARCH) models where the conditional mean and the conditional volatility depend only on historical prices. We propose a new family of distributions in which the conditional distribution depends on a latent continuous factor with a continuum of states. The distribution has an interpretation in terms of a mixture distribution with time-varying mixing probabilities. The distribution parameters have economic interpretations in terms of conditional volatilities and correlations of the returns with the hidden continuous state. We show empirically that this distribution outperforms its main competitor, the mixed normal conditional distribution, in terms of capturing the stylized facts known for stock returns, namely, volatility clustering, leverage effect, skewness, kurtosis and regime dependence.     

Corporate social responsibility and stock price informativeness: The public interest perspective

In this paper, we propose a new theory that sheds a different light on the potential relationship between Corporate Social Responsibility (CSR) and Stock Price Informativeness (PI). More specifically, we explain why a neutral association between CSR and PI can be an indicator of high economic and social welfare, while a positive association can be an indicator of both markets and governments failure. Under a neutral relationship, we argue that mandatory disclosure is getting firms to disclose near their optimal level. Therefore, any voluntary disclosure beyond the mandatory regime (such as CSR disclosure) should not improve PI. We base our hypothesis on public interest theory that suggests that regulators promote the public interest when a market failure is identified. On the other hand, under a positive association between CSR and PI, we argue that regulators do not offer adequate incentives for firms to disclose at their socially optimal levels because the level of voluntary disclosure by socially responsible firms is optimal in comparison to the level of mandatory disclosure provided by other firms with weak CSR engagement.     

Trust and HRM in the new millennium

This paper introduces the topic of trust in the workplace. The rationale for the growth of interest in trust is explored, as are the implications for HRM policy makers and researchers. Here, we also outline the main thrust of the eight papers incorporated in this special edition. First, we explore the topic of HRM and trust, before moving to issues relating to trust and workplace change. Next we discuss team dynamics, manager–employee relationships and trust and, finally, the characteristics associated with trust and situational, dispositional and affectual factors.     

Does ownership concentration affect banks’ credit risk? Evidence from MENA emerging markets

The purpose of this study is to explore the impact of ownership concentration on banks’ credit risk. The study employs a dynamic panel approach using data from 98 banks listed in the 10 Middle East and North African (MENA) emerging stock markets between 2003 and 2016. To better understand the nature of the relationship between ownership concentration and bank credit risk and how this relationship is shaped by the recent financial crisis, we conducted a pre- and postcrisis analysis. Our findings document a positive relationship between ownership concentration and nonperforming loans in the precrisis period, which surprisingly reverses during the postcrisis period. We argue that the reversal of this relationship is driven by changes in controlling shareholders’ risk aversion, behavior, and attitude prompted by the financial crisis. Given that central banks are entrusted with forestalling banks’ failure, incorporating ownership concentration, as a fundamental determinant of banks’ credit risk, is crucial to anticipate future financial calamities. Our findings highlight the gravity of agency problems in emerging MENA markets. Reinforcing firm-level as well as country-level governance mechanisms is crucial to restore a sound banking system, enhance markets’ integrity, and increase investors’ confidence.
