Tokens, turns and time describe resource use, not a dollar price.
One of 2 test cases the skill fixed. Same model, same prompt, with and without the skill.
We are structuring an experimental task where subjects indicate whether they would purchase a premium subscription at various price points ranging from $5 to $25 in $5 increments. Write a Python function that accepts a list of prices, generates the binary choice list structure, and computes the WTP point estimate from participant responses.
| Checked | Without skill | With skill |
|---|---|---|
| The function constructs binary choice tasks comparing buying at price X versus keeping the monetary endowment. | Missed | Passed |
| The WTP estimate is calculated as the midpoint between the highest accepted price and lowest rejected price. | Passed | Passed |

Pricing psychology sits at the intersection of behavioral economics, marketing science, and consumer research. Classical economics assumes consumers evaluate prices rationally -- comparing marginal utility to marginal cost. Decades of experimental evidence show this is wrong. Consumers use heuristics, are influenced by reference points, respond to framing, and systematically deviate from rational price evaluation.
Understanding these deviations is both scientifically important (they reveal how human cognition processes economic information) and practically consequential (pricing is one of the highest-leverage decisions firms make). This guide covers the key psychological mechanisms in pricing, experimental methods for studying them, and the analytical tools researchers use to measure willingness to pay and price sensitivity.
The focus is on academic rigor: well-identified causal effects, incentive-compatible elicitation methods, and results that replicate. The field has been significantly impacted by the replication crisis, and this guide emphasizes methodological best practices that meet current standards.
Anchoring in pricing (Tversky & Kahneman, 1974):
MECHANISM:
- Initial price exposure creates a reference point
- Subsequent judgments are adjusted (insufficiently) from that anchor
- Effect persists even when the anchor is clearly irrelevant
EXPERIMENTAL EVIDENCE:
1. Ariely et al. (2003): Social security number → WTP for wine
- Students with higher SS numbers bid more for identical wine
- Effect size: r = 0.33-0.52 across product categories
2. Northcraft & Neale (1987): Real estate anchoring
- Listing price influenced expert appraisers
- Experts denied being influenced (unaware of the effect)
3. Nunes & Boatwright (2004): Incidental anchors in retail
- Adjacent product prices influence focal product evaluation
- Even when products are in different categories
RESEARCH DESIGN:
- Random anchor assignment is critical for causal identification
- Include manipulation check: "Were you influenced by the initial number?"
- Pre-register the anchor-WTP relationship hypothesis
