Enterprising individual is a critical component of new business creation. While individuals’ psychological traits or demographic characteristics such as gender and ethnicity have been widely studied in entrepreneurship literature, very few researches have focused on age as a theoretically relevant attribute. By blending the entrepreneurial event model with the lifespan developmental perspective, this study investigates how individuals’ age affects people’s entrepreneurial cognition; in particular perceived desirability – the degree to which one finds a certain behavior to be attractive – and perceived feasibility – perceived personal capability to do a specific job or set of tasks. Recent entrepreneurship research suggests the importance of a life span developmental perspective, as it focuses on the study of individuals’ development, or ontogenesis, along one’s life span and is based on the assumption that such development does not cease whit adulthood; indeed, each major period of life is considered to have its own developmental challenges and achievements, and adaptive intellectual processes occur along the whole life span.
