Product Positioning in a Two-Dimensional Vertical Differentiation Model: The Role of Quality Costs

by Dominique Lauga and Elie Ofek

Abstract

We study a duopoly model where consumers are heterogeneous with respect to their willingness to pay for two product characteristics and marginal costs are increasing with the quality level chosen on each attribute. We show that while firms seek to manage competition through product positioning, their differentiation strategies critically depend on how costly it is to provide higher quality. When the cost of providing quality is not too high, firms use only one attribute to differentiate their products: they maximally differentiate on one dimension and minimally differentiate on the other dimension (a Max-Min equilibrium). Furthermore, they always differentiate along the dimension with the greater attribute range. As for the dimension with the smaller range and along which they agglomerate, both firms either choose the highest quality level or the lowest quality level possible, depending on whether the marginal costs of quality provision are low or intermediate, respectively. However, for larger quality provision costs, firms exploit both dimensions to differentiate their products. In particular, we characterize a maximal differentiation equilibrium in which one firm chooses the highest quality level on both attributes, while its rival offers the lowest quality level on both attributes (a Max-Max equilibrium). We discuss the managerial implications of our findings and explain how they enrich and qualify previous results reported in the literature on two-dimensional differentiation models.

In 2019, Chinese smartphone maker and telecommunications empire Huawei was preparing to launch its new flagship smartphone series, the Mate 30. After years of explosive growth, the previous 18 months had been a challenge for the company. In early 2018, Huawei’s planned smartphone launch in the U.S. had failed due to pressure from regulators who cited concerns about the company facilitating Chinese spying. Over the following months, a trade war between the U.S. and China had broken out, with Huawei at its epicenter. By mid-2019, after months of U.S. pressure and restrictions, Huawei found its supply chain for computer parts and software under siege and several governments around the world threatened to ban its 5G network equipment from their countries. In this unpredictable climate, Huawei founder Ren Zhengfei and his management team had to figure out not only how to successfully launch Mate 30 phones in the upcoming fall, but also how to ensure the company’s long-term viability.

Lemonade: Disrupting Insurance with Instant Everything, Killer Prices, and a Big Heart

Elie Ofek and Danielle Golan

Launching its first products in the fall of 2016 in New York, insurtech startup Lemonade was on a mission to disrupt the insurance market by using AI and behavioral economics principles. The company offered renters, homeowners, and condo insurance and mainly targeted millennial, tech-savvy individuals with relatively few assets—customers who were less attractive to traditional insurers who had costly, labor-intensive operations. By offering a delightful, bot-driven consumer experience, embracing a model that removed any incentive to deny claims and that let customers pick causes to donate leftover money, building a loveable brand, and employing creative digital advertising—the company was able to grow at an impressive pace. By the end of 2018, Lemonade was active in 24 U.S. states, had insured 425,000 customers, and was expecting sales (gross premiums) of over $57 million.
In an effort to sustain the spectacular growth momentum, the co-founders sought to pursue ambitious plans in 2019, including the launch of new insurance product lines as well as international expansion. But limited resources and scarce management bandwidth suggested that taking on both moves simultaneously could be highly risky. In deciding which path to take, the leadership team had to consider whether it was more important at this stage to scale globally with the current product lineup or to cover a breadth of insurance categories and stay in the U.S. for now. Assessing the relevance of the business model and the role of AI for each of these moves, understanding the nature of consumers in different markets, and foreseeing competitive pressures from both incumbents and startups were key in making the right call.
