The Discount Ratchet
Every promotion you run recalibrates your customer’s perception of what the price should be. That recalibration does not reverse when the sale ends.
You are not cutting the price; you are reducing what your customer will thereafter think the price should be.
The aspect of promotional pricing that is not included in the post-campaign analysis is the impact on the customer's long-term perception of the product's value—the figure they will use as a reference point for all future prices—which is never measured. That is why companies can repeat the same promotional cycle for years without understanding why full-price conversions continue to decline even as total revenue remains steady.
A promotion has the feel of a lever since, in the short term, it works like one: when you pull it, sales go up, and when you release it, the price goes back to normal. It is the same mechanism that makes the promotion seem reversible, which also makes it dangerous—the price reverts to the listed price whereas the customer's reference price does not.
Pricing Memory
People do not evaluate prices on an absolute basis; instead, they evaluate them relative to a reference point, which is typically the most recent or clearest price they have seen for the same or a similar product. Not the price the company sees as representing its true value, but the price the customer last saw the product sold for.
Reference-dependent preference was first articulated in the field of behavioral economics by Kahneman and Tversky's prospect theory in the late 1970s and has since been replicated across various consumer categories. The result for pricing is straightforward in that a discount does more than transfer value at the moment; it establishes in the customer's mind a new, lower reference price which stays there after the promotion has finished since that lower price has now become the most recent entry in the customer's memory of the product's price.
This strategy is so costly because of loss aversion. When the original list price is restored after a promotion, the customer does not see it as a return to normal conditions. Instead, they view it as a price rise, a loss—even if the product itself has not changed at all. The customer's reference price had dropped during the promotion, so bringing it back up means the company has to accept the impression that it has increased the price rather than simply withdrawing the temporary offer.
The pattern in each promotional cycle is that a new, lower reference point is set up, recovery movements back towards the list price meet with resistance, and the following promotion is then assessed in comparison to the most recent discounted price rather than being compared to the original list price; after several such cycles, the gap between the list price and the price that the customer perceives grows so large that full-price sales cease to be a reliable method of selling.
The price comes back to the listed price, while the customer's reference price does not.
The Ratchet
A ratchet is a device that goes smoothly in one direction but opposes movement in the other. In promotional discounts and pricing memory, the reference price drops rapidly. It stays at that lower level after each promotion, and only returns to a higher level slowly and only to an incomplete extent if the organization manages to maintain a continuous lack of discounting for a long enough period of time for the memory of the reduced price actually to fade, a situation which most organizations never manage to sustain before the next promotion once again resets the clock.
This situation becomes apparent because of the difference between the List Price and the Effective Reference Price, the actual figure derived from the customer's recent experience with promotions and used as the basis for assessing the current full price. If the gap is small, then the list price is about in line with the customer's expectations. But if the gap is large, the company is, in effect, using two prices – one being the list price, which is on paper, and the other being the effective price that matches what a substantial portion of the customer base actually expects to pay.
The diagram below illustrates the mechanism across five promotional cycles. With each promotion, the Effective Reference Price is reduced, with the reduction at each step greater than the previous one, since the starting point for the next discount has already been lowered by the earlier promotion. The list price remains unchanged and the gap between it and the Effective Reference Price, that is, the shaded Discount Dependency zone, increases in each cycle.
JCPenney's 2012 attempt to eliminate promotional pricing is the most studied example of a company trying to pull back from a fully mature ratchet without accounting for where the reference price had already been set.
The 'fair and square' pricing approach that Ron Johnson introduced substituted the previous practice of frequent coupons and sales with actually lower regular prices. Although the basic reasoning was sound, the strategy failed to account for the reference price the company had established over many decades through its own promotional activities. Customers, who had been used to looking for a coupon, did not see the new price as lower; instead, they regarded it as more expensive than the discounted price they remembered, since that discounted price was their point of reference. As a result, revenue dropped by 30 percent in the first year, and the strategy was reversed within 12 months.
The timeline for restoring a reference price that had been reduced over many decades seems to have been misjudged by JCPenney's leadership. Once a reference price has been established over thirty years of promotional activity, a single declared policy change is not enough to alter it. The ratchet drops quickly, but it takes a completely different amount of time to move it back up again.
RH, formerly known as Restoration Hardware, addressed the same issue differently. Instead of declaring that it would stop offering discounts and relying on customers' expectations to change, it reorganized the way in which customers obtained savings by introducing a paid membership that gives them a permanently reduced price, so that there is no need to wait for a sale since the membership itself functions as the equivalent of a discount. Customers did not lose their savings; the company eliminated the promotional cycle that had been gradually lowering the reference price.
Costco never had the ratchet; since there are no traditional promotional discounts, the reference price and the list price have never diverged meaningfully. Customers do not wait for a sale because the pricing model does not have one; the membership provides the value that would otherwise be offered through regular markdowns. The result is a customer base that has no memory of a previous lower promotional price against which to measure the regular price.
The mattress and furniture sectors are typical of a fully mature ratchet in a consumer market, since list prices serve almost entirely as fixed references for the final agreed-upon or promotional price, with discounting having become so standard that, for most buyers, an unchanged price seems more like a pricing mistake than a genuine offer. The list price now has no reference value and serves only as a starting point for a discussion that everyone involved knows will end with a 60% discount.
A promotion isn't a reversible lever; it's a one-way ratchet that affects how your customers perceive what you sell.
The Governance Gap
Almost everywhere, decisions regarding promotional pricing are the responsibility of teams focused on meeting targets for a single period. There is generally no way to monitor the cumulative impact of each promotion on the reference price, since this effect becomes apparent only gradually over several quarters and does not appear in the analysis following any individual campaign. The consequences are real and completely invisible to the people making the decisions that cause them.
Once you know what to look for, the diagnosis is simple: treat the full-price conversion rate as a separate figure from the overall conversion rate. If the full-price conversion rate is falling, even when total revenue remains stable, this is a clear sign that the gap between the list price and the effective reference price is widening. Revenue is being maintained because the volume of promotions is compensating the loss in full-price volume. This compensation is not free; it is the cost of operating the ratchet.
All effective structural responses follow the same line of reasoning: they don't require the customer to accept a higher reference price by exercising willpower or making a public declaration. Instead, they eliminate the promotional method that had been lowering the reference price and replace it with one that provides the same value without repeated discounts. This includes membership pricing, everyday low pricing, and structural bundling. What these approaches have in common is that they abolish the promotional cycle rather than addressing its consequences afterward.
Before the next promotion is given the go-ahead, the question we should be asking is not what impact it will have this quarter. However, that figure can be ascertained and is generally persuasive on its own. The right question is what effect it will have on the reference price against which all future full-price transactions will be evaluated. A discount that addresses this quarter's situation but increases the discount needed next quarter is not a solution; it is a loan, and its interest compounds.
The ratchet is patient. It doesn't announce when it has turned far enough that pulling it back becomes the problem. It just keeps moving.
Some ideas are worth discussing in the context of your organization.
