Author identity — read this first

The site owner’s academic name is Rafael Macedo-Rubião (hyphenated surname; changed from “Rafael M. Rubião” in September 2026). Use it everywhere his name appears: page text, _config.yml, the CV, and citations of his own work, which are written Macedo-Rubião, R. Never reintroduce “Rafael M. Rubião”, “Rubião, R. M.”, or an unhyphenated “Macedo Rubião”.

Deliberately unchanged (do not “fix” these): the GitHub handle and site URL (rafaelrubiao), email addresses, and the CV filenames files/Rubiao_RafaelM_CV.{tex,pdf} — kept stable so existing external links and the local build workflow don’t break.

Site facts

• Jekyll site on the academicpages theme (fork of Minimal Mistakes). GitHub Pages serves master; work on feature branches and merge via PR. Merge your own PRs yourself (squash) once tested: the owner does not want to click merge. The owner’s .claude/settings.json allows the GitHub merge tool.
• Content lives in _pages/: about.md (homepage, permalink /), research.md, code.md, qualtrics-llm.md (AI interview toolkit), cv.md. Custom styles in _sass/_custom.scss (imported from assets/css/main.scss); paper figures in images/wp-*.png.
• Availability polls: unlisted pages /femba-midterm/ and /emba-midterm/ (midterm TA sessions: 3-hour windows, Fri Oct 30 and Sat Oct 31, 9am-8pm PT; _pages/{femba,emba}-midterm.html → _includes/availability-poll.html, assets/js/availability-poll.js). Responses go to a Google Apps Script web app (_apps-script/availability-poll.gs, not published) that writes to the owner’s private Google Sheet; its URL is availability_poll_endpoint in _config.yml. The slot list (DAYS × TIMES) is defined in both the .js and the .gs file and must stay identical. Changing them needs the owner to paste the new .gs and deploy a new version; the first submission then erases the old answers (headerOk_/setup). /poll-results/ (_pages/poll-results.html, assets/js/availability-poll-results.js) shows the counts (never emails) to whoever types the password in the sheet’s Settings tab (B1).
• Unlisted class games: plain HTML files under games/ (e.g. games/bertrand/index.html → /games/bertrand/), shared by link only and never linked from the site. Each carries its own noindex tag; a _config.yml default keeps games/ out of sitemap.xml. Styled after the MGMT 405 course site (navy/gold, Carlito + Source Sans 3). The Bertrand game has four game types (Simultaneous default, where Airbus always charges its Nash price; Leader = the original game logic, except that Airbus’s prices are not rounded to whole dollars, since rounding let 290 or 294 beat the textbook 292; Follower; Collusion) and an algebra guide at games/bertrand/solve/, whose worked answers assume the default parameters (a=400, b=2, c=1, MC=232 for both firms): change the guide if those defaults change. A take-turns “Sequential” game was tried and removed: against a computer that reacts to the student’s price, it is Stackelberg in disguise.
• Research page convention: Working Papers (figure beside abstract), then Work in Progress, then Policy and Other Writings — lists, modeled on jpchauvin.com/papers.
• CV: edit files/Rubiao_RafaelM_CV.tex (pdflatex), recompile, and commit the refreshed files/Rubiao_RafaelM_CV.pdf alongside it.
• Build: bundle exec jekyll build (on Ruby ≥ 3.3, pin logger 1.5.x in a side Gemfile if the build crashes in Jekyll’s log adapter).
