This research examines how price discount, message assertiveness, and national culture interact to influence consumers’ response to the recycling messages on product packages. Results showed that American consumers respond more negatively to assertive (vs. nonassertive) recycling messages when paying a full price for the product, but they respond more positively to assertive (vs. nonassertive) messages when paying a discounted price for the product. For South Korean consumers, price discount and message assertiveness do not influence their responses to recycling advertising.
