/beamer-presentation

Builds LaTeX Beamer talks that share the paper's notation.tex macros and the same tabs/ and figs/ artefacts, so one rerun of the analysis updates paper and slides together and no number is ever re-typeset on a slide. Structures to an explicit time budget (15-20 min conference, 45-60 min seminar, 75-90 min job-market talk, 10-15 min policy briefing), one claim per slide, the claim in the frame title and the evidence in the body, detail pushed to backup slides for Q&A.

Beamer Presentation

Build clean, content-first academic slides in LaTeX Beamer that are reproducibly linked to the paper. The default style is metropolis-themed, 16:9, with the same notation.tex and tabs//figs/ artifacts as the paper.

Operating Principles

  1. Slides share the paper's source of truth. Same notation.tex, same tabs/*.tex, same figs/*.pdf. Rerun the analysis once; both PDF and slides update together. Never re-typeset a number on a slide.
  2. One claim per slide. If you need more, split.
  3. Headline, then evidence. The frame title states the claim; the body shows the evidence. Reviewers in the audience are skimming.
  4. Structure to time. A 20-minute talk is fundamentally different from a 90-minute seminar. Pin the time budget early; it determines depth, not just length.
  5. Backup, don't overload. Move detail into the appendix; reach for backup slides during Q&A. Better to be asked than to drown the talk in detail.

Decision Policy

This skill follows the repo-wide Agent Policy.

ASK before proceeding (blocking):

  1. Time budget (15-20 min conference / 45-60 min seminar / 75-90 min job-market talk / 10-15 min policy briefing).
  2. Audience expertise (specialists / broader economists / non-economists).
  3. The headline (one sentence the audience must remember).
  4. What goes in the appendix vs. the main deck.

DEFAULT + flag (use this default; tell the user how to override):

  • Theme metropolis, 16:9 aspect ratio, metroset{numbering=fraction, progressbar=frametitle}.
  • Frame title states the claim, not the topic ("Treatment increases outcome by 8%" not "Results").
  • Imports notation.tex, tabs/, figs/ from the paper directory — single source of truth.
  • Backup slides start at \appendix; one tightly-focused slide per anticipated question.
  • End on takeaways; do not end on "Questions?".

DOCUMENT and proceed (write into the deck preamble comment):

  • Time-budget allocation (slides per section).
  • Which paper artifacts the deck imports.
  • Any slide-only number that does not come from tabs/ or figs/ (rare; flag for review).

PROCEED items: slides imported from the paper's notation file; latexmk build; \Cref{} for cross-refs; \alert{} for the headline color (matched to figure palette).

Pre-flight Checklist

  • Format. Conference (15-20 min), seminar (45-60 min), job-market talk (75-90 min), policy briefing (10-15 min), thesis defense?
  • Audience. Specialists in the same subfield, broader economists, or non-economists?
  • What's the headline? State it now in one sentence.
  • What evidence is irreducibly part of the talk? (Identification, main result, robustness summary at minimum.)
  • What goes in the backup? (Detailed robustness, mechanism evidence, alternative specifications.)
  • Visual aids. Are there figures more compelling than tables? Almost always: yes.

Time Budget by Format

Text Only
15-20 min conference talk
└── ~12-15 content slides
    Motivation (2)  Question (1)  Strategy (2)  Results (4-5)
    Robustness (1)  Conclusion (1)  +backup
    Rule of thumb: 1-2 minutes per slide; never more.

45-60 min seminar
└── ~25-35 content slides
    Add: literature, institutional setting, mechanism, validation,
    extended robustness. Spend longer on the identification frame.

75-90 min job-market talk
└── ~40-55 content slides + 15+ backup
    Audience expects the full chain: motivation, contribution, model,
    data, identification, results, mechanism, robustness, policy,
    conclusion. Plan for 30+ min of Q&A.

10-15 min policy briefing
└── ~6-10 content slides; figures only.
    Lead with the policy-relevant headline; minimize regression tables.

The slide deck imports the same notation and references the same tabs/ and figs/ paths. This is DIME's single source of truth principle applied across artifacts.

Frame Recipes

Frame title = the claim, not the topic

Text Only
BAD:   "Results"
BETTER: "Treatment increases outcome by 8% (p < 0.01)"

Build complex claims incrementally

TeX
\begin{frame}{Treatment effect grows over time}
  \only<1>{\includegraphics[width=\textwidth]{figs/fig_event_static.pdf}}
  \only<2>{\includegraphics[width=\textwidth]{figs/fig_event_with_ci.pdf}}
  \only<3>{\includegraphics[width=\textwidth]{figs/fig_event_full.pdf}}

  \medskip
  \only<3>{\textbf{Takeaway:} effect rises monotonically through year~5.}
\end{frame}

Tables on slides should fit in 6-8 rows

For talks, regenerate a slide-friendly table from the same regression with esttab keep()/drop() options or a separate slides_tabs/ folder.

Common Pitfalls

  • Reading the slide. The slide is for the audience; the script is for you.
  • Tables with 12 rows of fixed effects. Cut to the headline coefficient + clearly labeled FE/N.
  • Equations no one will read. Show the estimating equation if it carries the identification; otherwise drop it.
  • Figures from screenshots of regression output. Always export from code.
  • A title slide with five logos and seven affiliations. One affiliation, one date, one venue.
  • "Questions?" as the final slide. End on the takeaway; questions are implicit.
  • 9-point font in a footnote no one will read. Cut the footnote.

Additional Resources

  • reference.md — extended patterns: theme tweaks, metropolis customization, equation reveal patterns, Q&A appendix structure, multi-author title page, animated coefficient plots.
  • examples/ — copyable Beamer files:
  • examples/preamble-beamer.tex — packages, theme, custom colors, frame title style
  • examples/slides.tex — master deck \input{}-ing notation + frame files
  • examples/frame_motivation.tex — motivation/question slide
  • examples/frame_strategy.tex — identification slide with equation
  • examples/frame_results.tex — main result slide with figure + takeaway
  • examples/frame_robustness.tex — robustness summary slide
  • examples/frame_conclusion.tex — takeaways slide

Cross-Skill Routing

  • For shared notation and the paper-side LaTeX scaffolding → latex-econ-model skill.
  • For slide-friendly versions of regression tables → latex-tables skill (keep(), drop(), alternative mtitles()).
  • For figures used on slides → econ-visualization skill (width = 10 in, height = 5.5 in for 16:9).
  • For the underlying paper draft → academic-paper-writer skill.
