The purpose of the present paper is to add to the small but growing number of studies that investigate individual-level factors in corporate entrepreneurship (e.g., Baron & Tang, 2011). We shed light on the question how employees can be influenced to act entrepreneurially on behalf of their employer. Employees contribute to organizational innovation through the generation of original and potentially valuable ideas concerning products, services, and processes (Zhou & George, 2001). We hence focus on idea generation. In developing our argument, we build on recent developments in creativity research and add personality differences provided by PSI theory (i.e., action- vs. state-orientation). In an experimental design with 328 employees we show that based on different abilities to self-regulate emotions––employees benefit best from different affective activations in order to fully unfold their creative potential.
