In recent years, the credibility of social science has been tarnished by widely discussed replication failures and a lack of reporting about what exactly researchers did when conducting their studies.In response, scholars, policymakers, and the public have called for greater transparency in social science research.In this chapter, I emphasize that transparency is an important public good.However, because individual researchers lack incentives to contribute to this public good, institutional solutions are needed.I discuss three institutions that facilitate transparency in experimental research:1) pre-registration, 2) reporting guidelines, and 3) the Data Access and Research Transparency (DA-RT) initiative.I also offer recommendations for what kinds of information researchers should pre-register and report in their published articles and appendices.I conclude with a discussion of how researchers might be incentivized to make greater use of these institutions when designing, conducting, and publishing their experiments.
