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 (p﹤0.05) varies...

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...

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...

Aghion, Van Reenen and Zingales (2013) find that institutional ownership causes an increase in innovation as measured by citation-weighted patent counts. To identify a causal effect, they use membership in the S&P 500 as an instrument for institutional ownership in a panel regression. We first...

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...

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...

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...

In New York City (NYC), it has been a common complaint that it is difficult to find a taxi in the rain. Using all Uber rides in NYC from April to September 2014 and January to June 2015, we show that the number of Uber rides is significantly correlated with whether it rained. The number of Uber...

We perform an empirical investigation of the socioeconomic determinants and consequences of all mass shootings in the U.S. from 2000 to 2015. We first manually search for and collect information on perpetrators. We find that approximately 40% (45%) of shooters were in financial distress...

In this ongoing project, we examine the short-term consequences of COVID- 19 on employment and wages in the United States. Guided by a pre-analysis plan, we document the impact of COVID-19 at the national-level using a simple difference and test whether states with relatively more confirmed...
