Have you ever seen your favorite chocolate is just a little smaller, there are fewer biscuits within the same-sized bundle or baggage of chips comprise extra air?
In the event you haven’t, you’re not alone.
What entrepreneurs name a “contents discount technique” is extra popularly often called “shrinkflation” – decreasing the dimensions of a product whereas the worth stays the identical.
It’s a relatively latest phenomenon within the grocery store enterprise, reflecting the strain on producers to maintain costs down. In truth the phrase “shrinkflation” entered the lexicon solely in 2009.
Since then, producers have “shrunk” the whole lot 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 modifications in costs and quantity sizes. Our outcomes present the innate cognitive bias customers have in the direction of specializing in value, 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 value.
We simulated this in real-world situations by manipulating customers’ 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 customers 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 value:
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 diminished (customary shrinkflation)
tactic 3 created the impression the dimensions has elevated, but in addition the worth had elevated much more
tactic 4 created the impression the product’s value had been diminished, but in addition the dimensions had been diminished much more (shrinkflation variant).
The next pictures present how we did this with the coconut rolls.
Examples of unit value growing techniques used within the area experiment, by altering the ‘Was’ value and dimension data.

The product and value by no means modified however the indicators indicating the earlier value and dimension did. In every case the “earlier than” per-unit value was additionally proven – an similar 38 cents per 10 grams.
The opposite two weeks had been used as “management” weeks. In a single week we displayed a “New Package deal” shelf ticket. Within the different management week we displayed a daily shelf ticket with out the phrases “New Package deal”.
What we discovered
Regardless that the modifications signalled by the shelf tickets represented an similar improve in per-unit value, the sale outcomes counsel customers discovered our shrinkflation variant essentially 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 items had been bought. This compares with 448 gross sales with tactic 3; 435 gross sales for tactic 2 (customary shrinkflation), and 391 gross sales for tactic 1.
The facility of framing
These outcomes display the industrial energy of psychological “framing”.
First, there may be the “silver lining impact” – a blended final result consisting of a small acquire (a cheaper price) and a bigger loss (a good smaller dimension) is extra beneficial than a internet final result consisting of only a smaller loss (value growing or bundle downsizing) alone.
This impact is tied to the “loss-aversion idea” developed by psychologists Daniel Kahneman and Amos Tversky, which says folks worth losses and positive factors in a different way.

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

Nonetheless, there’s no obligation to point out the “earlier than” unit value, so it’s troublesome to gauge unit value modifications.

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