This project aims to analyze how overconfidence impacts entrepreneurial performance, focusing on the channel of financial decisions. The study explores the link between overconfidence, financial choices (such as leverage), and the resulting impact on business performance. The opportunity lies in gaining an in-depth understanding of the mechanisms influencing entrepreneurial success, enabling improvement strategies to be devised. The main difficulty in exploring this question is the lack of data to link individual data on overconfidence with company-level data on financing and entrepreneurial performance. Access to data via the CASD represents a unique opportunity to build a database that meets these requirements
