Purpose-This study aims to examine relational norms in cross-cultural business settings. Cross-cultural business partners may differ in their normative orientations toward relational exchange. Owing to the high extent of international trade, there is a need for developing a more nuanced understanding of cross-cultural relational exchange. Design/methodology/approach-The repertory grid method was used to elicit the personal constructs characterizing the perceptions of business-to-business (B2B) relational exchange for 22 Russian and Finnish managers. These items were further categorized into categories of relational elements drawn from relational exchange literature using a content analysis. Then, the category means of scored importance and scored evaluations of domestic and foreign business partners were tested statistically. Findings-Relational norms of flexibility, information exchange, long-term orientation, mutuality and solidarity were equally important to both Russian and Finnish managers. The importance of a business partner's ability seems to be culturally dependent. Sharing the same cultural background might have an adverse effect when evaluating poorly functioning business relations. Research limitations/implications-The validity of these findings is limited to this context and material. Future research should repeat cross-cultural comparisons of the relational norms with more data and other nationalities. Practical implications-Firms should focus on long-term orientation and mutual targets to form well-functioning cross-cultural business relationships. Originality/value-This study provides new knowledge into B2B marketing literature by revealing the role of relational norms, business partner's ability and shared cultural background on functionality of cross-cultural business relations. It also demonstrates the use of the repertory grid method in studying perceptions of relational norms.
