The generation of ideas and the subsequent promotion and implementation of these ideas are important for organizational performance. Unfortunately, however, ideas do not always turn into innovations. Based on the ambidexterity theory of leadership for innovation, we argue that both employee idea generation and the relationship between idea generation on the one hand and idea promotion and idea realization on the other, could benefit from leaders who display both opening (fostering exploration) and closing behaviours (fostering exploitation). Results based on dyadic data (N = 201 dyads) partly supported our hypotheses, showing that opening leader behaviours were positively related to idea generation and subsequently to idea promotion and idea realization, and that closing leader behaviours strengthened the relationship between idea generation and idea realization (but not the relationship between idea generation and idea promotion). We discuss how our research contributes to knowledge about ambidextrous leadership and the relationship between idea generation and innovation.

Visionary leaders paint an image of the future with the intention to persuade others to contribute to the realization of that specific future. In the current study, we test the hypothesis that visionary leadership stimulates team creativity and innovation because visionary leadership promotes goal alignment amongst team members which, in turn, facilitates team creativity and innovation. In an experimental study (N = 50 groups), we found that goal alignment indeed mediated the relationship between visionary leadership and team creativity, but not between visionary leadership and team innovation. In a field study (N = 308 respondents) we found visionary leadership to be related to both team creativity and innovation through goal alignment. Moreover, the field study also showed that communication quality strengthened the relationship between goal alignment and team innovation. We discuss the theoretical and practical implications of visionary leadership in teams where creativity and innovation are desirable team performance outcomes.

In this paper, we address the relation between Leader-Member Exchange (LMX; the quality of the relationship between leader and subordinate), employee creativity (the generation of novel and useful ideas), and employee innovation (the promotion and implementation of these ideas). In the current set of studies, we test the competing hypotheses that LMX will either have a direct effect on employee innovation, or an indirect effect through employee creativity. In a field study of leader-subordinate dyads (N = 118), we found that LMX had no direct effect on employee innovation, and that employee creativity fully mediated the relationship between LMX and innovation. In a follow-up two-wave field study of employees (N = 398), we found that the LMX dimension professional respect predicted innovation through creativity, while the other dimensions did not. The results of this work indicate that research on LMX and innovation requires a multidimensional perspective, and that it may be valuable to differentiate between creativity and innovation.

Proactive behavior has emerged as a key component in contemporary views of individual work performance. Hence, a central question in the literature is how to enhance employees' proactive behavior. We investigated whether the more that employees experience a sense of vitality (i.e., energizing positive affect), the more likely they are to show proactive behavior at work, and whether this applies only to employees with a low personal fear of invalidity [(PFI) i.e., the inclination to be apprehensive about the risks/negative consequences of making errors]. Experimental (N = 354) and cross-sectional field (N = 85) studies provided consistent evidence for a positive relation between employees' sense of vitality at work and their self-rated proactivity. The predicted moderation effect was observed only for manager-rated proactivity. We conclude that feeling energized in the workplace is not necessarily associated with observable proactive behavior. It is only when employees experiencing a sense of vitality at work are not prone to fearing the risks/negative consequences of making errors that they are more likely to show observable proactive behavior in an organization.
