Abstract
Leadership and internationalisation are both established areas of scientific research, yet their interplay remains insufficiently examined. The present study focuses on the former and aims to shed more light on the intersection of leadership and internationalisation. By utilising fsQCA, a qualitative comparative analysis, to a set of 437 active international firms, results suggest that under distinct conditions transactional as well as transformational leadership can lead to a high level of internationalisation for both traditional internationalising and so-called 'born-global' firms.
