An application of the theory of planned behaviour is developed here to analyse factors in. uencing entrepreneurial intent among university students. The study provides a test of the robustness of the intent approach using international comparisons. The samples are from Finland (Helsinki University of Technology), Sweden (Linko¨ping University), USA (Stanford University and University of Colorado, Colorado Springs), and the UK (London Business School). The international comparisons indicate a good robustness of the model. Perceived behavioural control emerges as the most important determinant of entrepreneurial intent.
