Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Instrumental variables

An opinionated IV workflow grounded in a read canon (references/canon.md):
Imbens' Statistical Science perspective for the assumption structure and the LATE
estimand, Keane-Neal's Annual Review guide for the weak-instrument inference regime, the two
Borusyak-Hull(-Jaravel) papers for shift-share and formula instruments,
Mogstad-Santos-Torgovitsky's Econometrica framework for extrapolating beyond the compliers, and
Goldsmith-Pinkham-Hull-Kolesár's JEP operator's manual for leniency designs.
Deliverable: the recommendation with its citation, the R estimation and diagnostics code, and a
methods paragraph. The skill stops at the four stop points in
../causal-design/references/shared-rules.md (section "Stop points") and puts each choice to the user.

Current as of 2026-10-09; refresh per shared-rules (../causal-design/references/shared-rules.md,
section "Refresh path").
Nothing enters the canon without the user's approval.

## Six designs to recognize

Find your design here before reading about estimators. What each canonical case teaches is in
references/canon.md, section "Exemplar rows".

How to install

The exact contents, by fingerprint
mdr add ericluo04/claude-academic-workflow/iv@sha256:9c8feeac3df9001c

The line at the top of this page pins the label git:20261009.666cfcf, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
