This empirical article focuses on the phenomenon of trust and its infl uence on the trilogy of the following interrelated factors that are crucial to the success of international business cooperations and their economic results: knowledge creation, knowledge sharing, and knowledge transfer. Trust is expected and desired by many business partners, but it is also abused by others. The term trust, due to its intangible and invisible nature, is often ignored or superfi cially treated by companies. However, when trust does not exist between international cooperation partners or is not nurtured, negative relationships and fi nancial implications occur. These lacunae could be explained due to the difficulty in quantifying as a fi nancial asset. The article presents qualitative fi ndings (from two empirical research studies): (1) the implications of trust development for knowledge transfer between Russian-and German-speaking companies, and (2) the infl uence of trust on knowledge sharing in the completion of an Austrian construction project. The authors applied phenomenological interviewing and observations of critical incidents or signifi cant occurrences, combined with comparative content analysis. The positive infl uence of trust on the aforementioned trilogy results in higher levels of the involved companies' innovativeness, culminating in higher levels of competitive advantage and profi tability. The empirical fi ndings are presented to explain the infl uence of trust on knowledge creation, sharing, and transfer, which have a bearing on intercultural cooperations. One innovative fi nding relates to the differentiated perception of emotions and the implications that this entails.
