This repository contains the code used for the paper Is There a Replication Crisis in Finance? by Jensen, Kelly and Pedersen (2023). Please cite this paper if you are using the code or data:

}

Follow this link for a detailed documentation of the data sets.

The code consists of the following two self-contained components:

• GlobalFactors is a folder with code that creates data sets of global stock returns, firm characteristics, and global long-short factors. Note that the data can be downloaded without running the code. The global stock return and firm characteristics can be downloaded from WRDS (link). The long-short factors factor returns used in the paper (here) and the latest version of the factor returns (see weblink below). In addition, we keep a folder with the latest versions of the factor returns and additional data such as the underlying portfolios, market returns, and industry returns (link).

• Analysis is a folder that contains the analysis in the paper, including all figures and tables. This folder takes the global factors as input (either the ones that can be downloaded or the ones that you construct yourself).

See also the website https://JKPfactors.com/, where the most recent long-short factors can be downloaded using a simple drop-down menu.
