This study pushes our understanding of research reliability by reproducing and replicating claims from 110 papers in leading economic and political science journals. The analysis involves computational reproducibility checks and robustness assessments. It reveals several patterns. First, we...

International human trafficking of women for commercial sexual exploitation (henceforth trafficking) is an economic activity in which organizations try to make profits. Trafficking has been identified as a form of modern-day slavery and is a worldwide problem which has grown rapidly in the last...

This report presents a replication of Altindag et al. (2022) performed at the Olso Replication Games in 2022. Altindag et al. (2022) estimate the effects of an age-specific lockdown on mental health outcomes and mobility among adults aged 65 and older in Turkey, using a regression discontinuity...

This report presents a replication of Andersson (2019) performed at the Toronto Replication Games in 2023. Andersson (2019) estimates the effect of carbon taxes on CO 2 emissions in Sweden using the synthetic control method. His findings indicate a 10.9 percent reduction in emissions during the...

Islam (2019) reports results from a randomized field experiment in Bangladesh that examines the effects of parent-teacher meetings on student test scores in primary schools. The reported findings suggest strong positive effects across multiple subjects. In this report, we demonstrate that the...

We use a rigorous three-stage many-analysts design to assess how different researcher decisions—specifically data cleaning, research design, and the interpretation of a policy question—affect the variation in estimated treatment effects. A total of 146 research teams each completed the same...

This study evaluates the effectiveness of varying levels of human and artificial intelligence (AI) integration in reproducibility assessments of quantitative social science research. We computationally reproduced quantitative results from published articles in the social sciences with 288...

We investigate the effects of a large-scale Norwegian reform that provided extra teachers to 166 lower secondary schools with relatively high student-teacher ratios and low average grades. We exploit these two margins using a regression discontinuity setup and find that the reform reduced the...
