Drivers of customer likelihood to join grocery retail loyalty programs. An analysis of reward programs and loyalty cards

This paper aims to identify which personal features of customers may determine their likelihood to join a grocery retail loyalty program. We consider five aspects: price sensitivity, search for variety, shopping enjoyment, attitude toward loyalty schemes, and one personality trait: privacy concerns. Some of these variables have already been explored in the literature. Where our research breaks new ground is in establishing the difference between profiles of customers attracted by two of the most common types of loyalty programs currently used by grocery retail firms: a reward program and a loyalty card. The two kinds of program evidence differences in how they are managed, and we posit that the drivers of likelihood to take part in each are different. The study was carried out using logistic regression with a sample of 600 clients of a Spanish supermarket chain. Findings show that one particular type of customer is more likely to take part in these schemes: those displaying little shopping enjoyment, who are greatly concerned with privacy, and who show a favorable attitude toward loyalty programs in general. Furthermore, as expected, differences were observed between drivers of participation likelihood in reward programs and loyalty cards.
