Obese, low-cost retailers like Wal-Mart practice price discrimination by charging a premium for clothes consumed by overweight customers. If airlines can charge for overweight luggage, why can’t retailers charge extra for weight-sensitive apparel? Well, that depends on the market structure, pricing mechanism and demographic trends.
Despite the diet fads, workout programs, and calorie information on restaurant menus, the mismatch between the size of Americans and the clothing offered is creating a retail opportunity. The plus-size retail market has enjoyed an annual growth rate of 40 percent in the past decade, and according to market forecasts will shatter the $100 billion mark by 2012. Retailers like Wal-Mart, Target, and J.C. Penny are not only carving out a chunk of that pie, but also biting off an extra piece of the heavier consumers’ wallets.
Given the market landscape and the physical characteristics of the “typical” Wal-Mart shopper, it made business sense for the retailer to introduce plus-size clothing lines and capture consumer surplus by charging an extra $2. But the rationale behind this obesity discrimination needs re-evaluating.
Consumers and media buy into the argument for expensive plus-size clothing: On one hand, larger apparel uses more fabric, and in a highly competitive industry like textiles, price is extremely elastic with regards to production costs. On the other hand, a consumer population is normally distributed, where overweight individuals comprise only a small portion of the apparel market. As such, producers are unable to take advantage of economies of scale and drive down average cost per article of plus-size clothing. So, say retailers, that’s why prices are higher.
But these two arguments fall short if we consider demographic and market trends. First, the marginal cost of producing a XXL t-shirt versus an XL is no more than that of an M versus an S. In fact, marginal cost in the textile industry approaches zero as large quantities are produced. So why the premium on plus-sizes? Why don’t retailers discount XS goods that require less fabric?
Second, America’s bell-curve has shifted in the “heavier” direction. Just look at the state-by-state BMI statistics provided by the Centers for Disease Control and Prevention. Retailer claims that there’s not enough demand for large sizes isn’t warranted anymore.
So how are producers still able to get away with price discrimination? Why don’t plus-sized consumers revolt?
Two reasons: First, competition in big-and-tall isn’t as intense nor saturated with branded goods as the regular-size apparel market. Current market leaders are Charming Shoppes and Casual Male Retail, whose sales meet most of the demand, making market concentration low. Second, consumers have no substitutes for plus sizes. And that’s critical because shoppers cannot easily engage in product switching. So, in essence, consumers are stuck with fewer choices, and are at the mercy of retail pricing models.
Question is: How many industries will adopt the weight-based price discrimination model?
