Many green products are costlier than their nongreen counterparts, for a variety of reasons. This “green premium” is a key challenge marketers face when targeting con- sumers with these green products. A potential solution to this issue is provided by sig- naling theory. According to the theory, green products can have a signaling benefit. This benefit acts as an incentive for consumers to pay a premium for environmentally friendly products that can even out their price disadvantage (the green signaling hypothesis). Previous studies have tested the green signaling hypothesis with hypo- thetical buying decisions. The research at hand tests the green signaling hypothesis with incentive‐compatible purchase decisions in a laboratory setting with student subjects. As predicted, subjects exhibit a higher willingness to pay for green products when the product choice (a nongreen product vs. a costlier green counterpart) is pub- lic rather than private. The results also suggest that green signalers are treated more favorably in social interactions. The main result is that a signaling benefit can even out moderate green premiums. One implication of this is the idea that marketers should design green products that are costlier than their nongreen counterparts in a way that renders them clearly recognizable as green. At the same time, marketers should avoid marketing everyday green products with a high green premium.
