This paper contributes to the research on international joint ventures (IJV) in the following ways: (1) by identifying different patterns of governance that partners in the post-formation period exercise and examining how contrasting patterns relate to variations in perceived partner’s trustworthiness, as well as to IJV performance; (2) by empirically testing the extent to which partners emphasize or even renegotiate and change different elements of governance; and (3) by complementing existing studies that have examined only unidirectional links among trustworthiness, performance and governance by considering possible simultaneous relationships that may exist among these variables. The findings from a survey and follow-up interviews with international joint ventures located in Taiwan reveal that levels of partners’ trustworthiness and performance satisfaction each, by itself, may lead to the deployment of different governance measures. However, it is the combinations of extreme (high or low) variants on both partners’ trustworthiness and performance satisfaction that seem to generate clearer patterns of governance. Low satisfaction and partners’ trustworthiness seem to encourage intensification of control or the deployment of more aggressive governance measures. In contrast, high performance satisfaction and partners’ trustworthiness may foster a combination of soft and routine forms of control.
