Read MoreIn support of recent efforts by social scientists to address the ‘reproducibility crisis’, the Journal of Development Effectiveness (JDEff) recently devoted a special issue on replication research studies in its last issue of 2019. Most journals continue to favor new…
Read More[* EiR = Econometrics in Replications, a feature of TRN that highlights useful econometrics procedures for re-analysing existing research.] In recent years, DAGs (Directed Acyclic Graphs) have received increased attention in the medical and social sciences as a tool for…
Read MoreMicrofinance is one of the most hotly debated interventions in developing countries over the last 20 years. These are generally small loans, often given to women with short repayment periods and high interest rates (though often much lower than local…
Read MoreReplication is important. Many journals in economics, including Energy Economics, now insist on papers being published together with a replication package, and a few journals check that package prior to publication. This is a world apart from the common practice…
Read MoreConfidence intervals get top billing as the alternative to significance. But beware: confidence intervals rely on the same math as significance and share the same shortcominings. Confidence intervals don’t tell where the true effect lies even probabilistically. What they do…
Read More[* EiR = Econometrics in Replications, a feature of TRN that highlights useful econometrics procedures for re-analysing existing research. The material for this blog is primarily drawn from the recent working paper “Difference-in-differences with variation in treatment timing” by Andrew…
Read MoreWhat’s the true effect size? That’s my bottom line question when doing a study or reading a paper. I don’t expect an exact answer, of course. What I want is a probability distribution telling where the true effect size probably…
Read MoreReplication markets are prediction markets run in conjunction with systematic replication projects. We conducted such markets for the Replication Project: Psychology (RPP), Experimental Economics Replication Project (EERP), Social Science Replication Project (SSRP) and the Many Labs 2 Project (ML2). The…
Read MoreFor several years now scientists—in at least some disciplines—have been concerned about low rates of replicability. As scientists in those fields, we worry about the development of cumulative knowledge, and about wasted research effort. An additional challenge is to consider…
