Types of Product Differentiation: Horizontal vs. Vertical

Economic theory tells us that companies selling the same product on the market will ultimately end up in “perfect competition” with each making zero profit. Fortunately, this particular theory (like most others) offers us the starting point for us to better understand reality.

Using two ice cream vendors on the beach as an example, and following economic theory, the vendors would be physically located next to each other in the middle of the beach and would sell the same ice cream for the same price. Neither is hesitant to try to sell his product at a higher price than his competitor’s, and a “gentleman’s agreement” for both to keep prices high but the same will be short-lived. The temptation to grab more market share gets the better of him, and sure enough, one of the sellers starts the race to the bottom by lowering his price just a little bit. We know how that ends!

The reality, of course, is that companies DO make a profit, and one of the ways they do that is through product differentiation.

The assumptions that are established as part of the theoretical scenario give way and the market opens. For example, vendors would not sell the same ice cream because different consumers have different tastes. Furthermore, there is imperfect market transparency, which means that some consumers would only know the prices of one of the sellers. Other assumptions are also removed, and each plays a role in how the market reacts.

Product differentiation is beneficial if consumer preferences are heterogeneous. Factors such as technical features (cell phones), durability (shoes), resale value (real estate), taste/image (cars), location (gas stations or ice cream parlors), and time (flights) help consumers decide what the choice is. better for them. After all, customers determine the value of YOUR products. Not at some point. All time.

The product can be differentiated into two lines:

• horizontal differentiation – given equal prices, some consumers would choose product “A”, while others would choose product “B”
• vertical differentiation – given equal prices, EVERY consumer would choose product “A” over product “B”

Back on the beach (and who doesn’t like the sound of THAT!), we can find an ice cream vendor walking away from the middle. This allows you to increase your price because it is more conveniently located for people at one end. Seeing this, the second ice cream vendor does the same and moves a little further from the middle as well, only in the opposite direction. This “Horizontal Differentiation” example also allows you to raise your prices. Each seller, who is now selling their products at a higher price than before, is making more profit. The supporting factors that positively influence prices and profits in this example of horizontal differentiation are:

• the distance of the vendors from each other
• the magnitude of the consumer’s discomfort from having to walk a certain distance
• the number of consumers on the beach

Applying an element of vertical differentiation, suppose one supplier sells a premium ice cream while the other sells an inferior product. If the prices were the same, all consumers would choose the seller with the premium brand. Knowing this, the seller with the inferior ice cream lowers the price of it. Assuming his costs are also lower, he can still make a profit, even at lower prices. The first seller may raise his prices, considering that his target market will pay more for the superior product. And so it goes, the low end can further lower your product quality (and costs) and the high end can go as high as your customer base will allow. The supporting factors that positively influence prices and profits in this example of vertical differentiation are:

• the difference in the quality of the products
• the degree of heterogeneity in terms of consumers’ willingness to pay

The end result, and we see it all the time, is that companies that offer lower quality products stand to make huge profits, just like companies that offer higher quality products.

A healthy exercise is for manufacturers to understand whether they can be more profitable by implementing horizontal product differentiation or vertical product differentiation. There is very real potential for even bigger profits.
