The general aim of the current project is to particularly investigate the contribution of sleep status on decision-making and entrepreneurial performance and test whether sleep-promoting interventions would lead to differential impacts in these outcomes. We suggest that impairments in sleep severely affect risk perception in decision-making and thus the performance of entrepreneurs. Building on the self-regulatory resource and the effort recovery models, we also contribute to the literature by evaluating the outcomes of interventions that address sleep through pre- and post-tests (withinsubject design) across different groups (between subject design). In addition, by integrating sleep and cognitive literature in the context of entrepreneurship, we investigate how cognitive errors, particularly “overconfidence”, mediate the effect of sleep on entrepreneurial decisionmaking and performance. Within the scope of the project, two studies will be carried out, one of which is an observationalstudy and the other is a longitudinal intervention study, both carried out in the field. Specifically in Study 1, we seek to determine if entrepreneurs' sleep habits significantly affect their decision-making processes and, consequently, their performance. Furthermore, we will establish whether overconfidence mitigates this effect and how this relates to changes in related biological and physiological mechanisms. In Study 2, we will determine how the implementation of 16 weeks of a sleep promoting intervention affects entrepreneurs' decision-making processes and performance as well as changes in related biomarkers and physiological data. 3 Considering the interdisciplinary integration of organizational psychology, entrepreneurship, decision-making, and sleep, this project will contribute to different and important streams of research. By including a longitudinal study, combining data from different sources – self-reports, biomarkers and physiological data -, we will be able to draw causal inferences about the effect of sleep in an entrepreneurial context. Completing the project successfully will provide beneficial intervention techniques for entrepreneurs to break the vicious circle of sleep problems and entrepreneurial performance. In addition to these, it is planned that the results obtained from the project will be published in high-ranked journals and the project outputs will be presented at national and international conferences abroad.
