Beamer Presentation Creator

Purpose

This skill helps economists create professional academic presentations using LaTeX Beamer. It provides templates for conference talks, job market presentations, and seminar presentations with proper structure and clean aesthetics.

When to Use

• Preparing conference presentations
• Creating job market talk slides
• Making seminar/workshop presentations
• Converting a paper into presentation slides

Instructions

Step 1: Understand the Context

Ask the user:

1. What type of presentation? (20-min conference, 90-min seminar, job market)
2. What's the paper/project about?
3. What's the target audience expertise level?
4. Do they have specific style preferences?

Step 2: Structure by Time

Step 3: Follow Presentation Best Practices

• One idea per slide
• Minimal text - use bullets of 3-6 words
• Big fonts - minimum 20pt for content
• Consistent colors - use a limited palette
• Reveal incrementally using \pause or <+-> for complex slides

Theme Recommendations

Best Practices

1. One message per slide - if you need more, split it
2. Use figures over tables when possible
3. Highlight key numbers in results tables
4. Build complex slides incrementally with \pause
5. Prepare backup slides for anticipated questions
6. Practice timing - 1-2 minutes per slide max

Common Pitfalls

• ❌ Too much text on slides
• ❌ Reading slides word-for-word
• ❌ Tables with too many columns
• ❌ Skipping the roadmap/preview
• ❌ Ending with "Questions?" instead of takeaways
