This paper tests the hypothesis that transaction cost determinants play a major role in defining the level of resource commitment in international joint-ventures. A sample of international joint-ventures involving Italian firms is used to differentiate the factors that influence the determinants of management costs and transaction costs. The findings support the hypothesis that the previous distinction is an important one. The results of this study also indicate that the level of international experience and the perceived distance affect the decision of resource commitment. Relationships between these central constructs are drawn and implications for understanding their influence on the level of resource commitment are discussed.
