The current publication system in economics has encouraged the inflation of positive results in empirical papers. Registered Reports also called Pre-Results Reviews are a new submission format for empirical work that take pre-registration one step further. In Registered Reports researchers write their paper before the data collection and commit to a detailed data collection process and analysis plan. After a first-stage review a journal can give an In-Principle-Acceptance guaranteeing that the paper will be published if the authors carry out their data collection and analysis as pre-specified. We here propose a practical guide to Registered Reports for empirical economists. We illustrate the major problems that Registered Reports address (p-hacking HARKing and publication bias) and present practical guidelines on how to write and review Registered Reports (e.g. the data analysis plan power analysis and correction for multiple-hypothesis testing) with R and STATA codes.
