Income and green purchase intention nexus: A systematic literature review

This study addresses the intricate causality between income and green purchase intention, aiming to understand how income-green purchase is influenced by demographic factors, including age, gender, environmental consciousness, and sociocultural influences. Through a systematic literature review, theoretical frameworks such as the Theory of Planned Behavior, Value-Belief-Norm Theory, and Behavioral Reasoning Theory are explored to elucidate the multifaceted nature of this relationship. The study examines whether income influences environmentally friendly purchasing behaviors positively, negatively, or non-linearly and identifies potential moderating factors (demographic factors) that may affect this relationship. Findings reveal a complex interplay among various factors, challenging simplistic assumptions about income's role as the sole determinant of green purchasing behavior. While income significantly influences attitudes and behavioral intentions towards green products, its impact is shaped by other demographic variables and contextual factors. Therefore, this study underscores the importance of considering a range of demographic, attitudinal, and cultural factors in promoting sustainable consumption and green product adoption. Practical insights and managerial implications are synthesized to guide businesses and policymakers in developing effective strategies. Overall, this study contributes to advancing knowledge in the field of environmentally conscious consumer behavior, emphasizing the complex interplay of income and demographic influences in shaping green purchase intentions.
