An investigation of the impact of sustainability drivers and transformative mediators on green buying behavior in the US and Brazil

Abstract

PurposeThis study compares the impact of three drivers of sustainability behavior (perceived quality, social influences, and online education) and three transformative mediators (price value, attitude, and environmental knowledge) in influencing green buying behavior in a developed versus a developing country.Design/methodology/approachData was collected through a self-administered online survey in the United States (n = 195) and in Brazil (n = 209). The hypothesized model was tested using structural equation modeling software. Multi-group analysis was conducted to compare the impact of drivers and mediators on consumers' intention and willingness to buy green products and services between the two country groups.FindingsThe direct effects of price value, attitude, online education, and environmental knowledge, together with the indirect effects of perceived quality, social influence, and online education explain a significant amount of variation in driving consumer sustainability behavior in both countries. Differences between countries indicate that cultural and country's level of economic development moderate some relationships in the model. Affordable prices and social influences are stronger in Brazil.Practical implicationsOrganizations must educate consumers on relevant socio-ecological issues and communicate the positive aspects of their sustainable offerings as a proactive way to change consumers' attitude toward sustainability behavior, while recognizing the influence of family and friends in collectivist societies and price value in emerging markets.Originality/valueThis study is unique in drawing from three theories of green buying behavior and for empirically demonstrating the importance of distinct drivers and mediators under the context of countries in different stages of economic development (developed and developing). It provides a more global perspective on the topic and highlights the influential power of the key transformative mediators in the model.
