This project will train PhD students in Economics, Political Science, and other empirical social sciences in methods for transparent, open and reproducible research. There is no course offering such training at the EUI currently and this project will provide an opportunity for PhD students to develop an essential toolkit on research transparency and reproducibility. Topics will include pre-registration and pre-analysis plans and, ethical issues regarding the protection of human subjects in experimental work, data de-identification, data mining, fishing, p-hacking, selective reporting outcomes and multiple inference correction, meta-analysis, and reproducible workflows.
