Question

Many supermarkets provide regular shoppers with "loyalty cards." By swiping the card when checking out, a shopper receives reduced prices on a few goods, and the supermarket compiles information on all the shoppers' purchases. Some supermarkets have switched from giving the same price reductions to all shoppers to giving shoppers differing price reductions depending on their shopping history. A manager at one supermarket that uses this approach said, "It comes down to understanding elasticity at a household level." a. Is the use of loyalty cards that provide the same price discounts for every shopper who uses them a form of price discrimination? Briefly explain. b. Why would making price discounts depend on a shopper's buying history involve "understanding elasticity at a household level"? What information from a shopper's buying history would be relevant in predicting the shopper's response to a price discount?

Short answer

The use of loyalty cards where every shopper receives the same discounts is not a form of price discrimination since there is no difference in prices based on shopper's behaviors or characteristics. Making discounts dependent on a shopper's buying history involves understanding elasticity at a household level because the shopping history can help predict how a shopper will respond to a price change, and thus, can influence supermarkets' pricing strategies.

Step-by-step solution

Understanding price discrimination

Price discrimination is a pricing strategy that charges customers different prices for the same product or service based on certain criteria. In the context of the supermarket loyalty cards that offer the same discounts to all customers, it isn't considered as price discrimination, as all customers have the opportunity to receive the same discounts regardless of their shopping habits or preferences.

Understanding elasticity at a household level

Elasticity at a household level is a measure of how households alter their demand or supply of a good when prices change. Understanding elasticity at this level involves predicting the shopper's response to a price discount. If a consumer has a more elastic demand for a product, they are more likely to increase their quantity demanded if the price decreases. This could impact supermarkets' pricing strategies.

Utilizing shoppers' buying history

Information from a shopper's buying history that would be relevant in predicting their response to a price discount could include frequency of purchases, types of goods bought, their reaction to previous price changes, and the quantity of goods bought at different price levels. This information can help in predicting demand elasticity for individuals, thereby helping the supermarket in determining which shoppers to target with specific price discounts.

Conclusion

In conclusion, using loyalty cards that provide the same price discounts is not a form of price discrimination since all shoppers get the same price reductions. However, customizing discounts based on shopping behaviors involves understanding elasticity at a household level meaning supermarkets are trying to utilize the buying history of shoppers to predict their response towards price changes, thereby indirectly practicing price discrimination.

Key concepts

Elasticity in Supermarket Pricing

In the world of economics, elasticity refers to how much the quantity demanded or supplied of a product changes in response to changes in price. When it comes to supermarkets and loyalty cards, understanding elasticity at the household level becomes crucial.
By analyzing the buying patterns of individual households, supermarkets can predict how sensitive shoppers are to changes in price. For example, if a household shows a high elasticity for coffee, it means that a small drop in price might significantly increase their quantity purchased. Conversely, a low elasticity indicates that price drops will not greatly affect the quantity they buy.
Supermarkets use this information to tailor their pricing strategies, ensuring they can maximize sales and revenue by offering discounts to those most likely to respond with higher purchases. This tailored approach also helps supermarkets manage stock and improve customer satisfaction.

The Role of Loyalty Cards

Loyalty cards are more than just a tool for rewarding frequent shoppers; they also serve as a powerful data collection device. When customers use loyalty cards, supermarkets gather valuable data about their purchasing habits. This data can include how often they shop, what products they buy, and their sensitivity to changes in price.
Loyalty cards can create a direct line of communication between the supermarket and the customer, allowing stores to learn about what their shoppers prefer and how they respond to various promotions. They help in building customer profiles that highlight buying behaviors.
By analyzing this data, supermarkets can implement price discrimination, where they offer tailored discounts based on individual shopping histories. This personal approach not only enhances the shopping experience by making customers feel valued, but it also allows supermarkets to run more targeted promotions, increasing customer loyalty and minimizing unnecessary price cuts.

Pricing Strategy Using Loyalty Programs

Supermarkets employ strategic pricing techniques to increase profitability and customer loyalty. One such technique involves using insights from loyalty programs to inform pricing strategies.
Pricing strategy in this context includes setting prices and discounts that align with the elasticity insights gained from shopping data. Information gathered through loyalty programs allows supermarkets to identify which goods to discount and to what extent to offer these discounts to maximize profitability.
A strategic approach means not all products get the same discount and not all customers receive the same offers. Instead, supermarkets analyze the elasticity data (how much a household's purchase behavior changes with price changes) and alter prices accordingly. For instance, if a household frequently responds to discounts with increased purchases, they might receive more targeted offers.
This personalized approach to pricing ensures that supermarkets offer the best deals to their most responsive customers, preventing over-discounting while maintaining customer satisfaction and loyalty.
