Abstract

The increasing debate on corporate ethics raises the question of whether consumers are willing to reward and punish corporate behaviour based on its ethicality. In this context, this article investigates the direct effect on consumers' willingness to pay. Price response to product‐related ethical information is explored in an experiment dealing with social issues in sportswear and environmental issues in consumer electronics. It is shown that in both areas, consumers demonstrate an increased willingness to pay for ethically produced goods. However, the response is subject to a negativity bias. In contrast to prior research that used abstract stimulus measures, a ratio for quantifying this bias is suggested based on consumers' willingness to pay and their price expectations. This measure allows us to analyse a consumer's individual bias.
