STATA code pattern library for empirical archival accounting research. Provides tested syntax from 126 peer-reviewed JAR (Journal of Accounting Research) replication files (2017-2025). Use when the user asks procedural questions like "How do I implement [method]?" or "Show me code for [technique]" — including: entropy balancing, propensity score matching (PSM), difference-in-differences (DiD), regression discontinuity (RDD), instrumental variables (IV), event studies (CAR/BHAR), survival analysis, Fama-MacBeth regressions, bootstrap, quantile regression, reghdfe/xtreg/areg, clustering standard errors, fixed effects, esttab/outreg2 table formatting, winsorization, leads/lags. Users can specify their variables (e.g., treatment, outcomes, controls) and receive adapted syntax. NOTE: This skill provides code patterns from published papers, not research design advice.

Match a pasted list of academic references against the Crossref REST API and produce a four-column markdown table (original, matched, confidence, flags) with canonical APA citations and DOIs. Use whenever the user pastes a bibliography or reference list and wants to verify, clean up, canonicalize, or find DOIs for those references — triggers include "verify bibliography", "match these references", "find DOIs for this reference list", "canonicalize my citations", "clean up the reference list against Crossref", "check these citations", or any pasted block of academic references accompanied by a request to normalize them.

Search Scopus and retrieve paper metadata via pybliometrics. Use whenever the user wants to find papers, build a literature corpus, get abstracts, retrieve references, or prepare data for bibliometric analysis. Triggers: "search Scopus", "find papers on", "literature search", "Scopus query", "get abstracts", "download paper metadata", "bibliometric data", "co-citation", "knowledge graph", pybliometrics, or any academic paper discovery task. Also triggers when filtering by journal tier (ABDC, AJG, FT-50) — integrates with biz-journals skill.

Generate Scopus ISSN boolean queries based on academic journal rankings (ABDC, AJG, FT50). Use whenever the user wants to build a Scopus search query filtered by journal quality, asks about journal rankings or grades, needs ISSN lists for specific journal tiers, or mentions Scopus queries, journal ranking systems, ABDC, AJG, ABS list, Academic Journal Guide, or FT50. Also triggers when users ask which journals are in a particular ranking tier, or want to restrict a literature search to top-tier outlets.
