The purpose of the present paper is to contribute to the small but growing literature studying the role of individual-level factors in corporate entrepreneurship. Specifically, we draw on the volitional core of the broader personality-systems-interactions (PSI) theory (Kuhl, 2000) to analyze how leadership behavior and affect influence the creative performance of employees. Creativity is widely considered to be core to entrepreneurship as it is conducive not only for exploring new opportunities but also for a variety of other key activities in entrepreneurship such as resource acquisition and networking activities. PSI theory explains human personality functioning in terms of its underlying mechanisms by stating that the personality of individuals accounts for the capability to regulate affect (Kuhl, Kazén & Koole, 2006).
