What’s on the Elasticity poster
A 4-row table: Elasticity · Measures · Reading.
The four measures.
- Price (PED) — Demand response to own price — Negative; >1 elastic
- Income (YED) — Demand response to income — Positive = normal good
- Cross (XED) — Response to another's price — Positive = substitute
- Supply (PES) — Supply response to price — Rises with time available
Negative income elasticity identifies an inferior good — demand falls as people get richer.

- Who is the Elasticity poster for?
- Elasticity belongs to the Economics section rather than to a school year, because business is not something one grade owns. Anyone learning microeconomics can pin it up — a beginner, a student mid-course, or someone revising years later.
- When should you use the Elasticity poster?
- Elasticity is responsiveness. The sign tells you direction; the size tells you strength. A wall chart earns its place by being glanceable from where the work is happening, so Elasticity belongs on the wall where that business work actually happens, within glancing distance, rather than filed away.
- What other posters go with Elasticity?
- Firm Objectives, Consumer Choice and Efficiency & Welfare sit alongside Elasticity in the Economics section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Firm ObjectivesConsumer ChoiceEfficiency & Welfare
- Is the Elasticity poster free to download and print?
- Yes. Elasticity downloads as a free PDF with no account, no email and no watermark, like everything else in the Economics section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
- What size does the Elasticity poster print at?
- Elasticity is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Elasticity loses nothing.Printing guide
