Have you ever seen your favorite chocolate is slightly smaller, there are fewer biscuits within the same-sized package deal or luggage of chips include extra air?
If you happen to haven’t, you’re not alone.
What entrepreneurs name a “contents discount technique” is extra popularly referred to as “shrinkflation” – decreasing the scale of a product whereas the worth stays the identical.
It’s a relatively current phenomenon within the grocery store enterprise, reflecting the stress on producers to maintain costs down. In reality the phrase “shrinkflation” entered the lexicon solely in 2009.
Since then, producers have “shrunk” every part from jars of Vegemite, Maltesers, Tim Tams, Freddo Frogs and Corn Flakes. In the UK, the Workplace for Nationwide Statistics counted 2,529 examples between 2012 and 2017.
So why does shrinkflation appear preferable when it’s successfully the identical as placing up the worth?
To research this, we performed experiments enjoying with shopper perceptions of adjustments in costs and quantity sizes. Our outcomes present the innate cognitive bias consumers have in direction of specializing in worth, it doesn’t matter what.
How we examined the shrinkflation impact
In our experiments we wished to measure the relative impact of various methods to extend a product’s per-unit worth.
We simulated this in real-world circumstances by manipulating consumers’ perceptions of merchandise on the market in a grocery store in Brisbane, then measured the variations in gross sales. The experiment took six weeks and concerned 5 merchandise – coconut rolls, confectionery, biscuits, soy milk and coconut water.
We modified neither the worth nor dimension of those merchandise. However we did change the shelf tickets, to control consumers into believing the worth or dimension had beforehand been completely different.
Every week over 4 weeks we modified the shelf tickets to check the next 4 situations, all implying an similar improve within the per-unit worth:
tactic 1 created the impression solely the worth had elevated
tactic 2 created the impression the worth was the identical however the dimension had been lowered (normal shrinkflation)
tactic 3 created the impression the scale has elevated, but in addition the worth had elevated much more
tactic 4 created the impression the product’s worth had been lowered, but in addition the scale had been lowered much more (shrinkflation variant).
The next photos present how we did this with the coconut rolls.

The product and worth by no means modified however the indicators indicating the earlier worth and dimension did. In every case the “earlier than” per-unit worth was additionally proven – an similar 38 cents per 10 grams.
The opposite two weeks have been used as “management” weeks. In a single week we displayed a “New Bundle” shelf ticket. Within the different management week we displayed a daily shelf ticket with out the phrases “New Bundle”.
What we discovered
Regardless that the adjustments signalled by the shelf tickets represented an similar improve in per-unit worth, the sale outcomes counsel consumers discovered our shrinkflation variant probably the most engaging.
The next chart reveals the gross sales figures for all 5 merchandise over the six weeks. With tactic 4 (our shrinkflation variant) 530 models have been bought. This compares with 448 gross sales with tactic 3; 435 gross sales for tactic 2 (normal shrinkflation), and 391 gross sales for tactic 1.
The facility of framing
These outcomes display the business energy of psychological “framing”.
First, there’s the “silver lining impact” – a combined end result consisting of a small achieve (a lower cost) and a bigger loss (a good smaller dimension) is extra beneficial than a web end result consisting of only a smaller loss (worth rising or package deal downsizing) alone.
This impact is tied to the “loss-aversion principle” developed by psychologists Daniel Kahneman and Amos Tversky, which says folks worth losses and positive aspects in a different way.

Second, worth is extra noticeable and is given extra weight than dimension. Thus consumers have been influenced extra by the worth drop than by the discount in package deal dimension.
We attribute this to an computerized cognitive response – folks have inherent desire towards decrease costs.
Unit pricing is vital, however not sufficient
In most developed international locations, shopper safety legal guidelines require retailers to show unit costs to allow consumers to chop via the proliferation of selling alerts designed to draw consideration.

Nevertheless, there’s no obligation to indicate the “earlier than” unit worth, so it’s tough to gauge unit worth adjustments.

It appears to be equally vital for retailers to promote unit worth adjustments to assist shoppers make extra knowledgeable purchases.
However our outcomes affirm what entrepreneurs have clearly gleaned over the previous decade. Customers’ cognitive biases are robust. So you may anticipate ever extra shrinkflation and for ever extra “worth drop”, “low cost”, “new worth” and “worth match” tickets to adorn grocery store cabinets.
