This article reviews and summarizes current reproduction and replication practices in political science. We first provide definitions for reproducibility and replicability. We then review data availability policies for 28 leading political science journals and present the results from a survey...

A typical empirical study involves choosing a sample, a research design, and an analysis path. Variation in such choices across studies leads to heterogeneity in results that introduce an additional layer of uncertainty not accounted for in reported standard errors and condence intervals. We...

Placebo tests, where a null result is used to support the validity of the research design, is common in economics. Such tests provide an incentive to underreport statistically significant tests, a form of reversed p-hacking. Based on a pre-registered analysis plan, we test for such...

A fundamental question to the scientific enterprise is to what extent published scientific findings are credible. This question is related to the reproducibility and replicability of scientific findings where reproducibility is defined as testing if the results of an original study can be...

Alan et al. (2023) carry out a field experiment where they randomly allocate 20 corporations in Turkey to a treatment group or a control group. White-collar employees at the headquarters of the corporations are invited to participate in a training program to improve the workplace environment....

We estimate the robustness reproducibility of key results from 17 non-experimental AER papers published in 2013 (8 papers) and 2022/23 (9 papers). We find that many of the results are not robust, with no improvement over time. The fraction of significant robustness tests (p0.05) varies between...

Berger, Easterly, Nunn and Satyanath (2013) find that increased US political influence, arising from Cold War interventions, was used to create a larger export market for American products. They find that after CIA interventions, US imports increased dramatically, and the authors rule out other...

Naidu and Yuchtman (2013) find that labor demand shocks in 19th-century Britain had an impact on master and servant prosecutions, as breaking an employee contract was a criminal offense until 1875. We first reproduce all regression tables in Naidu and Yuchtman (2013) and then test for robustness...

Cloyne (2013) constructs a novel dataset documenting fiscal tax shocks in the United Kingdom using the narrative approach developed by Romer and Romer (2010), and estimates the impact of tax changes on GDP. He finds that a tax cut of one percent of GDP causes a 0.6 percent increase in output in...

Pop-Eleches and Urquiola (2013) apply a regression discontinuity to the Romanian secondary school system, and notably find that (a) students who go to a better school get higher scores on an exam used for university admission, (b) parents of students who get into a better school help their kids...
