Disengagement from the startup up process, i.e. seizure of all activities geared toward firm creation, warrants concern because nascent entrepreneurs invest significant (and often limited) time and resources in startup activities. In line with calls for a cumulative combination of related theories within the self-regulation perspective (e.g., Wood, 2005), we attempt to expand existing understanding of the role of cognition in entrepreneurship by employing an integrated goalsetting and social cognition approach under the self-regulation perspective in examining nascent entrepreneurs’ disengagement from the startup process. We present a model which proposes that nascent entrepreneurs’ goal commitment (H1a) and self-efficacy (H1b) negatively influence their disengagement from startup efforts while perceived competition intensity (H1c) increases disengagement. Further, both of the former relationships are moderated by perceived competition intensity – being weaker when perceived competition intensity is high (H2a & H2b).
