OpenEconometrics

Replication labs

Each replication lab takes a published economics paper, starts from the author’s own research files and rebuilds its main results in OpenEconometrics, number by number. Read the scorecards below; each lab shows whether its package and video are available.

How a replication lab works

  1. Step 1

    Start from the author’s files

    Download the paper’s official replication archive. We never redistribute it; the lab checks every file against a recorded fingerprint.

  2. Step 2

    Run one script

    Once the lab package is available, open it in OpenEconometrics and press Run. It rebuilds the inputs, the models and the paper’s tables and figures.

  3. Step 3

    Compare every number

    A scorecard puts each published result next to ours, and keeps every difference visible instead of hiding it.

  4. Step 4

    Learn with the lesson

    Published video lessons explain the economics, the method and what the replication can and cannot show. Check each lab for availability.
