Tensions in Practice: A discount can become a resale route¶
Two prices for the same fictional admission
Imagine a seller listing the same admission at 4 for eligible buyer A and 8 for buyer B. Production cost is identical. Eligibility is correctly checked at purchase. A can offer an unused ticket to B for 6 if tickets are transferable: A gains 2 over the purchase cost and B pays 2 less than the direct price. Compare transferable tickets with tickets usable only by the named purchaser. These are possible routes, not simultaneous purchases or predictions that anyone will trade.
Allow tickets to move
Let an unused admission be given or sold to someone else.
Keep segment prices separate
Make the purchase eligibility apply to the person who actually uses the ticket.
Why these aims pull against each other
A purchase check separates buyers, but a transferable admission reconnects them after purchase. Binding use to identity removes that route while also removing legitimate transfer.
Choose an arrangement to see what changes and what remains difficult.
Arrows are possible ticket or admission routes. Prices 4, 6 and 8 are invented; each ticket admits one user once. Removing the horizontal resale route does not change the listed prices.

Compare the arrangements
Transferable tickets
Either buyer can purchase directly; A may instead transfer the lower-priced ticket to B for the stipulated 6. One ticket admits one user once.
- What it protects
- An unused ticket can move to another willing attendee without a name-change process.
- What it costs
- The low-price route can supply a high-price buyer; checking eligibility at purchase alone does not preserve the intended price separation.
- When it fits
- Plausible when transfer freedom and reuse matter more than maintaining this segment price gap, and the seller accepts the resale exposure.

Named-user tickets
Purchase remains available at the same two prices, but admission checks the named purchaser. A’s ticket cannot admit B through the modeled transfer route.
- What it protects
- The declared price gap is not bypassed by this A-to-B resale path.
- What it costs
- Name checking consumes effort and identity information; legitimate gifting or resale cannot use this simple route.
- When it fits
- Plausible when the segment policy is justified, named-use checking is feasible, and its privacy and transfer costs are acceptable.

What this illustration does—and does not—establish
The source establishes the structural tension; the concrete alternatives and their conditional costs are editorial synthesis. No arrangement is a universal recommendation.
- The currency units, prices, eligibility classes and resale offer are invented. No demand curve, welfare result, revenue forecast or legal conclusion is supplied.
- Named use blocks only the specified resale mechanism. Impersonation, credential sharing, refunds and authorized reassignment would require separate rules.
- A can either attend or transfer the single ticket; the diagram shows available routes, not duplication of admission.

Segmentation Signals vs Arbitrage Barriers
The seller needs observable or self-selected signals that correlate with willingness to pay (student ID, age, channel, time of purchase, product variant chosen) *and* barriers that prevent low-price buyers from reselling to high-price buyers.
