Consumers' willingness to pay for corporate social responsibility: Theory and evidence

In an era when consumers believe that businesses should engage in corporate social responsibility (CSR), it is vital to understand how it affects consumers' willingness to pay (WTP) for the goods and services offered by such businesses. There is a need for an in‐depth study into the relationship between CSR and WTP, and to identify the mediators and the moderators affecting this relationship. To investigate this, we conducted a systematic literature review based on a preliminary search result of 116 unique articles indexed on this topic in four bibliographic databases—Scopus, Google Scholar, Dimensions and Web of Science—published over the previous seven decades. The findings confirm the overall positive effect of CSR on WTP. This study also reveals the indirect effect between CSR and WTP, mediated by variables like Brand Trust, Brand Loyalty, Brand Love, Customer Satisfaction, Brand Attitude, Purchase Intention and Brand Equity. The relationship is impacted by moderators, including demographics, cause‐based aspects, company characteristics, personal aspects and types of products. The theory explaining the evidence of each of these aspects provides a deeper understanding of the relationship between CSR and WTP, and the intervening variables. Based on these, a conceptual framework of this relationship involving all the variables is developed. The Theory, Context and Method (TCM) framework is employed to identify gaps and systematically make recommendations for future research. The findings of this study will aid marketers in developing pricing strategies based on a thorough understanding of consumer behaviour in terms of CSR perceptions. Scholars can use this study's conceptual framework to examine previously unexplored relationships. As the literature on CSR and its influence on consumers' purchase behaviour grows, this comprehensive systematic literature review on the effects of CSR on WTP fills an important gap.
