Hong Kong SAR's government faces the dual challenges of volatile revenue and medium term spending pressures arising from a rapidly aging population. Age-related spending pressures raise long-run sustainability concerns, while revenue volatility creates risks to service provision, possibly...

Purpose – The purpose of this research is to study the relationship between the HR control system and organizational results, examining the moderating effect of uncertainty and HR risk behavior. Design/methodology/approach – The study analyzes the relationship between HR control systems and...

Incorporating managerial flexibility in an innovative R&D project is important, because managers face greater uncertainty in today's competitive and dynamic changing environment. It is essential to bring managerial flexibility into R&D project planning to decrease technical and market risks,...

Purpose – In this two-part series, this paper seeks to consider certain intriguing aspects of randomness, the basic mathematical concept used to model financial risk and other unknown quantities in the physical world. Design/methodology/approach – Part 1 applies concepts from quantum physics...

Purpose – To study the effect of Knightian uncertainty – as opposed to statistical estimation error – in the evaluation of value-at-risk (VaR) of financial investments. To develop methods for augmenting existing VaR estimates to account for Knightian uncertainty....

Purpose – For publicly traded firms, calculating the cost of capital is predicated typically on information from the financial markets. Small businesses do not have the necessary market-based information. As an alternative to traditional proxy approaches, this paper presents a multi-criteria...

An optimal maintenance approach is a key support to industrial production in the contemporary process industry. This paper presents a Multiple-Criteria Decision Making (MCDM) methodology for selecting the optimal mix of maintenance approaches – Corrective Maintenance (CM), Time-Based...

In this paper we introduce a spectral control chart that is designed to detect the onset of cyclic behaviour in a process, even in the presence of multiple cycles. This new spectral control chart is based on the periodogram test proposed by Bølviken (1983a, b). While no more difficult to...

Financial time series have two features which, in many cases, prevent the use of conventional estimators of volatilities and correlations: leptokurtotic distributions and contamination of data with outliers. Other techniques are required to achieve stable and accurate results. In this paper, we...
