“…Following the suggestions of Antončič et al (2015) and somewhat less so the findings of Rauch and Frese (2000 , 2007) , we found that the Big Five are the most important for starting companies, with specific motivational personality characteristics also being important, and sociological factors being less important. This study contributes to past research on entrepreneurial personality (e.g., Antončič et al, 2015 ; Murugesan and Jayavelu, 2017 ; Şahin et al, 2019 ; Sahinidis et al, 2020 ; Salmony and Kanbach, 2022 ) and sociological determinants of entrepreneurship (family entrepreneurial background, e.g., Dombrovsky and Welter, 2010 ; Schenkel et al, 2013 ; Marques et al, 2018 ; Mitrovic Veljkovic et al, 2019 ; Georgescu and Herman, 2020 ; Lee et al, 2021 ; local supportive entrepreneurial background, e.g., Reynolds et al, 2005 ; Wong et al, 2005 ; Hisrich et al, 2013 ) by developing the model and providing evidence about the relative importance of psychological and sociological factors for business start-up intentions and behaviors. This study contributes in terms of methodology to research on the Big Five personality characteristics and entrepreneurship (e.g., Murugesan and Jayavelu, 2017 ; Şahin et al, 2019 ; Sahinidis et al, 2020 ; Salmony and Kanbach, 2022 ) by using a sub-sample of actual entrepreneurs and three variables of entrepreneurship.…”
