The ReplicationWiki provides an overview of published empirical studies in the social sciences with information on data and code availability, data sources, and software. One can search for keywords, Journal of Economic Literature codes, and geographical origin of data. It informs about 670 replications, that is studies reanalyzing previously published results, as well as corrections and retractions. The wiki helps researchers to compare their results to those of previous studies. It is a resource that helps to identify useful teaching examples for statistical methods, replication and studies of social science. It allows advanced students and practicing researchers to find guidance on how to publish their replication research in various journals. A collection of teaching resources, useful tools, and literature helps instructors to integrate replication into their teaching and students to integrate open science practices into their own research. With the ongoing expansion of the wiki, currently covering more than 4,500 empirical studies, it is becoming an ever more powerful tool for social science research and education. It is a crowd-based platform where users can add their own replication results, suggest studies that should be replicated, and identify for example further data sources used in the empirical studies, especially ones from countries underrepresented in the literature and for whom economic policies are thus difficult to investigate.
