Although there is abundant literature on entrepreneurial intentions and entrepreneurial behavior, there is still a lacuna on those factors enabling the pass from intention to action. Motivated by this gap, this study assesses the extent to which the determinants of entrepreneurial intention also have an effect on subsequent entrepreneurial behavior, using an institutional approach as a theoretical framework. With a sample of 2,491 university students from Catalonia (Spanish) through the simultaneous equations, the main findings show that institutions such as opportunity identification, business skills, and entrepreneurs' status encourage students to think of entrepreneurship as a good career choice, which subsequently explains entrepreneurial actions. Theoretical, policy, and practical implications are discussed based on these findings.
