Purpose The purpose of this paper is to investigate the correlation between ethical leadership (EL), collaborative culture (CC), knowledge-centered culture and employees’ behaviors toward knowledge sharing (KS) in Chinese firms. Design/methodology/approach The paper used structural equation modeling to examine the level of how EL, CC and knowledge-centered culture impact on tacit and explicit KS of employees via the data collected from 319 participants in 51 Chinese firms. Findings The research findings show collaborative and knowledge-centered culture mediates the relationship between EL and employees’ KS behaviors. It highlights the necessity of practicing EL style to develop a positive climate aimed at positively improving tacit and explicit KS of employees. Research limitations/implications Future studies should focus on investigating the relationship between EL, CC and knowledge management process or the other variables to explore and maximize their potential and benefits toward key organizational outcomes. Practical implications This paper offers leaders a deeper understanding of the effective pathways to build positive climates for fostering employees’ tacit and explicit KS. Originality/value This paper is unique in the attempts to increase the understanding of moral lens by which EL might successfully arouse a positive organizational culture and foster KS behaviors in their firms.

Purpose The purpose of this paper is to discuss and test the direct and indirect effects of utilitarian, hedonic and social values integrated into the theory of planned behaviour (TPB) to achieve a deeper understanding of consumers’ intention to adopt mobile commerce (MC) in the context of a developing country, Vietnam. Design/methodology/approach Based on self-administered survey data of 382 Vietnamese consumers, a structural equation modelling approach with latent constructs is used to test the hypotheses. Findings Perceived values explain consumer attitudes, subjective norms and behavioural intentions in the MC context. In particular, they help to increase the explained variance of the intention to adopt MC by about 9.58 per cent compared with the TPB. Finally, a cross-effect on consumer attitudes from subjective norms is also found. Research limitations/implications Future studies would benefit from investigating other variables (e.g. innovativeness or trust) and using actual behaviour (e.g. online purchases). Practical implications Business managers should pay attention to different forms of consumer values to understand how and why consumers adopt MC in a developing country. Originality/value This study fills the gap in the literature by simultaneously investigating the role of utilitarian, hedonic and social value in a TPB model in the MC context.
