This paper aims to study the effects of perceived organizational support (POS) on employees’ knowledge sharing intention (KSI). More specifically, this study examined whether these effects are moderated by job characteristics (JCs) and are mediated by organizational citizenship behavior (OCB).

Data for 426 employees were collected via an online questionnaire from four IT companies in South Korea. Combined effects in the variable set were analyzed using conditional process analyses (Hayes, 2013).

The results indicate that POS positively affects OCB and KSI, and that JCs moderate the relationship between POS and OCB. Also, the relationship between POS and KSI is mediated by OCB, and the hypothesized moderated mediation model is confirmed.

This study is novel in empirically establishing how employees’ KSI is affected by POS as an integrative construct bringing together JCs and OCB. This paper intends to fill a methodological gap and nurture future research by adopting conditional process analyses assessing whether JCs moderate the relationship between POS and OCB and mediate the effects of OCB on KSI.

This research examines the effects of winning–losing perception, generated from success and failure results, on consumers’ risk preference.

Using different manipulations of success and failure and different measurements of risk preference tendency, the authors conducted five experiments to carry out the research.

Using different manipulations of success and failure and different measurements of risk preference tendency, five experiments were conducted to demonstrate that a clear success increases consumer’ sense of power, which in turn raises their subsequent risk preference; a clear failure, however, decreases consumers’ sense of power, which in turn reduces their subsequent risk preference. Furthermore, a close result can moderate this effect; that is, the difference between narrow-winners and narrow-losers’ risk preferences is weakened.

This study further enriches the research on the impact of winning–losing perception on individuals’ behavior and provides suggestions on how to use the results of online and offline competitions to carry out marketing activities.
