The present study aims to elucidate the mediating role of relational energy between empowering leadership and its attitudinal (employee engagement), behavioral (knowledge sharing) and performance (task) related outcomes, respectively, and the moderating role of autonomy between empowering leadership and relational energy, using the social cognitive theory.

The study used surveys in the small and medium-sized enterprises sector and collected time-lagged data to address common method variance and reveal causal relationships. AMOS was used to conduct hypothesis testing.

The results suggest that empowering leaders have a positive impact on outcomes such as employee engagement, knowledge sharing and task performance, and this impact is mediated by relational energy. Autonomy moderates the empowering leaders and relational energy relationship, strengthening it when autonomy is high.

Organizations should focus on leadership development programs depending on the need. Empowering leadership should be promoted to get positive attitudinal and behavioral outcomes in terms of employees. Empowering the employee in terms of decision-making helps motivate employees to perform better.

The study contributes to the empowering leadership literature by associating social cognitive theory. Empowering leaders has the potential to increase employee engagement, knowledge sharing and task performance.

The complexity of property valuation, coupled with valuers’ cognitive limitations, makes some degree of error inevitable in valuations. However, given the crucial role that valuations play in the efficient functioning of the economy, there is a need for continuous improvement in the reliability of reported values by enhancing the quality of the decision-making process. The purpose of this paper is to review previous research on valuation decision-making, with particular interest in examining the approaches to improving the quality of valuation decisions and identifying potential areas for further research.

The paper adopts a narrative approach to review 42 research articles that were obtained from Scopus and Web of Science databases and through author citation searches.

Our findings show that existing literature is skewed towards examining the use of technology in the form of decision support systems (DSS), with limited research attention on non-technological (i.e. behavioural) approaches to improving the quality of valuation decisions. We summarise the non-technological approaches and note that much of the discussions on these approaches often appear as recommendations arising from other studies rather than original investigations in their own rights.

We conclude that studies investigating the effectiveness of the non-technological approaches to improving valuation decision-making are lacking, providing various avenues for further research.

This paper presents the first attempt to provide a comprehensive overview of non-technological approaches to improving the quality of valuation decisions.
