PurposeThis study aims to determine the influence of relationship marketing on consumer behavior in the fine arts sector. Specifically, it examines the relationship marketing dynamics that significantly impact art enthusiasts' intention to purchase and their satisfaction with the artist.Design/methodology/approachThe proposed model was tested through the “structural equation modeling” technique to explain how and to what extent each variable affected purchase intention and satisfaction. Using a paper-based and online survey method to gather data, the authors analyzed 303 responses from art students, art collectors and art dealers in Mongolia. Eight hypotheses, including two mediating hypotheses, were developed and tested.FindingsThe results indicated that relationship investment and communication significantly influence trust, satisfaction and purchase intention, while trust significantly influences satisfaction and purchase intention. The study also assessed the vital role of trust as a mediator.Practical implicationsThe study's results provide insights that may help artists, art collectors and art dealers promote and improve the sales of their art products. The interactions demonstrated between the construct reveal essential implications for art marketers interested in relationship marketing strategies.Originality/valueThis study is the first to explore the application of relationship marketing in the fine arts industry.
