Project Description

Summary:  View help for Summary This is data and code accompanying the article "Selective reporting of placebo tests in top economics journals". The abstract for that paper is the following: Placebo tests provide incentives to underreport statistically significant tests, a form of reversed p-hacking. We test for such underreporting in 11 top economics journals between 2009-2021 based on a pre-registered analysis plan. If the null hypothesis is true in all tests, 2.5% of them should be significant at the 5% level with an effect in the same direction as the main test (and 5% in total). The actual fraction of statistically significant placebo tests with an effect in the same direction is 1.29% (95% CI [0.83, 1.63]), and the overall fraction of statistically significant placebo tests is 3.10% ((95% CI [2.2, 4.0]).

Methodology

Sampling:  View help for Sampling We collected data on placebo tests for papers published in 12 top journals in economics that reported at least one placebo test One of these 12 journals (Economic Journal) was included in a pilot study conducted prior to posting a pre-analysis plan, and papers from this journal are therefore not included in any hypotheses tests.
