What Determines Consumer Value?
Is it ethically OK for a manufacturer to reduce the amount of product in a package, but to keep charging the same for it?
Here’s an interesting example. The image shown here shows three varieties of Kraft Peanut Butter — Smooth, Extra Creamy, and Whipped. Notice that all three varieties are in jars of the same size, and all three cost the same. The ingredients are also virtually the same. But notice also that the one on the right — the Whipped peanut butter — includes one special ingredient not listed on the label. That ingredient also happens to be one that is free to the manufacturer, and that takes up a lot of space in the jar. That ingredient is air.
Yes, whipping peanut butter (like whipping cream or anything other liquid or paste) adds air to it. It fluffs it up. So if you look closely you’ll see that the label on the jar of Smooth peanut butter indicates that its contents weigh 1 kilogram (1000 grams). But the label on the jar of Whipped peanut butter indicates that its contents weigh just three quarters of a kilo, or 750 grams. The result is that when you buy a jar of whipped peanut butter, you’re getting 25% less peanut butter, or a jar that is effectively 1/4 full of air.
From a manufacturer’s point of view, this is wonderful. Being able to charge just as much while reducing the amount, and cost, of ingredients by a quarter is something of a coup.
Is it fair to the consumer? Or is the consumer being ripped off, getting less peanut butter for the same price? Is the consumer getting less value?
Well, no, I don’t think the consumer is being ripped off, though I suspect some will disagree with me. The 750g jar of Whipped peanut butter contains no less value than the 1000g jar of Smooth peanut butter precisely because there’s nothing to say that 750g of the one is less valuable than 1000g of the other. They’re different products, despite having the same ingredients. The value of a thing is absolutely not determined by its ingredients; all that its ingredients (or rather their cost) determines is the lowest level at which the product could be sold without the seller suffering a loss. A thing’s ingredients no more determine its value than does the amount of labour that went into it.
Or rather, no one can say that 750g of one thing is worth less than 1000g of the other, other than the customer. What matters is how the customer values those two things. If the customer finds 750g of Whipped PB to be as useful to them as 1000g of Creamy, then charging the same price seems perfectly fair. Consumers who disagree are naturally free to object — that is, to refuse to make a purchase. But that, I’m afraid, would be akin to cutting off their noses to spite their faces.
