The purpose of this paper is to explore why impulsive buying happens under emergency and crisis situations, such as that of COVID-19. Drawing on the cognitive-affective personality system theory (CAPS), we tested the dynamic influence of daily perceived uncertainty on COVID-19 on daily impulsive buying via daily information overload and daily information anxiety in a two-wave experience sampling method (ESM) design. Through a multilevel structural equation model (MSEM) analysis, we found that the daily perceived uncertainty on COVID-19 affected daily information overload, which in turn stimulated daily information anxiety, ultimately determining the daily impulsive buying. Namely, daily information overload and daily information anxiety played a complete chain-mediating role between the daily perceived uncertainty on COVID-19 and daily impulsive buying. The present paper is the first to uncover the important dynamic effect of the perceived uncertainty on COVID-19 on impulsive buying with diary data. Specific implications of these findings are discussed.

Purpose: The purpose of this paper is to explore the relationship between temporal leadership and employees' innovative behavior while considering the competitive mediators of harmonious and obsessive passions in work situations, along with the moderating role of synchrony preference.Design/methodology/approach: Insights from the literature and affective events theory (AET) underpin the hypotheses on whether and how temporal leadership would affect employees' innovative behavior. A total of 365 responses were received, and 336 questionnaires were considered for the analysis. This paper examined the whole model through a path analysis using Mplus 7.4.Findings: The results indicated the significant effect of temporal leadership on innovative behavior through harmonious passion which is moderated by synchrony preference, such that the positive effects are stronger when employee's synchrony preference is higher.Originality/value: This paper contributes to the emerging literature on temporal management by examining the path of temporal leadership→ job passion→ innovative behavior to deepen knowledge of how temporal leadership may impact employees' innovative behavior. This paper also proposed a collaborative model related to temporal leadership and the synchronization of employees, providing a powerful explanation for the boundary conditions of temporal leadership.
