Abstract

The effects of coupons on brand choice and repurchase behavior were examined in a laboratory panel experiment. Each of the 122 consumers purchased a candy bar on 10 different occasions; on the seventh purchase occasion, each consumer received an announcement of a new candy bar and one of four versions of a coupon. Results showed that whether or not a consumer will use a coupon depends on the size of the coupon offer, how easily the consumer can redeem the offer, how brand loyal the consumer is, and whether or not the consumer is deal prone. We also found, after statistically adjusting for our censored sample, that loyalty and coupon Characteristics influence whether or not a consumer will continue to purchase a formerly discounted brand. Information aggregation theory (Tybout & Scott, 1983) explains better than attribution theory how the coupon affects repurchase decisions.
