AI agent for economists

Peer Review Replication Agent

Reproduce a paper's main results or explain exactly why they differ.

Peer Review Replication Agent: what goes in, what the agent does and what you get

What it does

Replicating a paper means rebuilding the data, rerunning the model and checking that the coefficients match, which can take weeks. This agent reads the paper and its replication files and lists the data, sample rules, variables and model specification. It rebuilds the dataset, runs the model and compares each coefficient and standard error with the published table. When something differs, it investigates in order: sample size, variable definitions, data versions and software options, rerunning after each change. It stops when it matches or all causes are explored, and writes a replication note listing what matched. The economist approves the conclusions before anything is shared.

How it works

Follow the arrows from top to bottom. The orange dashed arrow is the loop: when a check fails, the agent goes back and tries again.

Read the steps as a list
  1. Paper assigned for replication
  2. Read the paper and list data, sample rules and the model
  3. Rebuild the dataset from the files
  4. Does the sample size match the paper?If not: review sample rules and missing data handling, then rebuild. Back to step 3.
  5. Run the model
  6. Compare coefficients and standard errors with the paper
  7. Do all main results match within rounding?If not: test data versions, variable definitions and software options one by one. Back to step 3.
  8. Record each difference and its cause
  9. Write the replication note
  10. Economist approves the conclusionsThe agent waits here for your OK.

How it decides

It treats a result as replicated when coefficients agree within rounding, and otherwise tests listed causes in order of likelihood.

  • Count a coefficient as matching within 1 percent
  • Test sample rules before variable definitions
  • Try the stated software version before others
  • Report unexplained differences as unresolved, not as errors

Make it yours

Every agent is a starting point. You choose these settings for your own situation.

  • Matching tolerance (default 1 percent)
  • Software and version
  • Tables to replicate
  • Note format

What keeps you in control

It always asks you first

  • Economist approves the conclusions
  • Economist approves contact with the paper's authors

Hard limits

  • Never accuses authors of error
  • States every difference with evidence

It stops when

  • Done: results match or all causes are explored and documented
  • Stop: data files are not available

An example run

What happensThe paper reported 2,412 observations and a coefficient of 0.31 on trade exposure. The agent first got 2,466 observations. The sample check failed, and the paper excluded firms with missing sales, which it applied. The sample then matched at 2,412 and the coefficient was 0.31, but one standard error was 0.09 instead of 0.07, traced to clustering. The economist approved the note.
