MIT Labor Market Lecture Redesign: Data Tables to Charts Transformation — Before & After

Why This Deck Needs a Redesign

This lecture from MIT 14.771 — Labor Markets (Development Economics, Ben Olken, Fall 2021) covers signaling, working conditions, and multinational labor policy. The research is rigorous, but the LaTeX/Beamer presentation buries critical findings in impenetrable regression tables:

📊 Dense regression tables with raw coefficients and standard errors — unreadable at a glance, requiring mental parsing of each cell
🔲 LaTeX-generated Beamer tables lack visual hierarchy — all rows look equal, making it impossible to spot key results
⚡ No visual distinction between statistically significant and insignificant results — asterisks are the only cue buried in dense numeric grids
📋 Multiple panel tables (Panel A, Panel B) crammed into single slides with no visual separation between groups
📝 Text-heavy bullet point slides with minimal formatting — flat lists with no structure or visual anchors
🎨 Bland default Beamer template with no visual identity — generic blue header bar repeated across every slide

Arty's redesign transforms every regression table into intuitive visual charts — horizontal bar charts for treatment effects, dot plots with confidence intervals for audit experiments, and grouped comparison charts for multi-panel results. Text slides receive structured card layouts with icons, while preserving every data point and statistical finding from the original.

Other Issues — Search Platforms & Job Training

Bullet points about search platforms and job training with no structure. The redesign uses a clean card layout with structured content sections and visual anchors.

Before

Flat bullet points, no visual structure, wall of text

After
