Under development — library extension. This report is part of the expanded-library work, not the original collection. Source preparation, methods and results are subject to revision.

Provisional eligibility assessment — under development. Race-by-decade indicators trace changes in racial wage gaps with rich individual/composition effects. Race is not a policy adoption, and a collection of binary interaction columns does not create the template intervention. This working assessment is not fully vetted and may change.

Under development — community extension. This is a provisional source-design assessment, not a new successful replication or a final eligibility ruling.

Source design and template applicability

Race-by-decade indicators trace changes in racial wage gaps with rich individual/composition effects. Race is not a policy adoption, and a collection of binary interaction columns does not create the template intervention.

No DiD estimates, uncertainty intervals or homogeneity-test decision were computed in this tranche. No point is added to the calibration plots. This is not a zero effect or a failed statistical test.

Recorded treatment-column measurement

3 distinct nonmissing values in race.

Original NLSY race categories, before race-by-decade interactions and demographic sample restrictions. N=460,894; missing=0. Frame: selected_source_data. Source: /Volumes/LAL_BAK/did-cardinality-work/packages/Hurst_Rubinstein_Shimizu_AER_2024_197928/data/deming/nlsy_merged.dta.

These are the existing data-measured counts, not counts inferred from design labels. A binary instrument, group indicator or interaction component need not be the treatment of interest; the source-design assessment above takes precedence for template applicability.

Replication status

This tranche: unsupported design; source code/documentation inspected, no estimator run.

Supplied library: verified; verification: verified; preparation: needs_helper_files. These are the library’s labels, not new verification claims. Missing data and unsupported designs are separate issues.

Evidence and provenance

The following files in the supplied library were inspected. Their SHA-256 digests are recorded in the downloadable assessment JSON. Source archives and microdata are not redistributed.
