The reproducibility crisis, first highlighted by loannidis [2005] and confirmed by numerous studies, has raised concerns about the reliability of scientific findings. Although economics displays a relatively high replication rate, it remains vulnerable to publication bias, p-hacking, and the file-drawer effect. Open science offers solutions to strengthen the credibility of research. Three levers are essential: open access to publications, data, and code; pre-registration and registered reports to limit analytical biases; and the systematic replication of studies. By examining their mechanisms and challenges, we emphasize their impact on scientific reliability. The adoption of these practices marks a turning point toward a more robust and cumulative science, but it requires changes in academic incentives, institutional support, and collective commitment to ensure the reproducibility of research.JEL Codes: C90, C91, C92, B41, C83.
