It is a general understanding that higher education has characteristics of an "experience good" because the quality cannot be determined before receiving the service, which induces information asymmetry. In response to reducing the asymmetry, external assessment tools like international accreditations have emerged in higher education, which is especially evident in the field of business and management research. Quality is an integral part of reputation and legitimisation, so business schools actively engage in the accreditation race. In order to ensure legitimacy in the higher education market, business schools pay special attention to their intellectual output. It is reflected in the development of academic policies designed to encourage publication activities. It is pivotal to analyse how international accreditations contribute to the research performance and impact of business schools. The results of the study provide evidence that AACSB accreditation contributes to the research performance, however, it does not contribute to increasing the impact of the papers. Since the signalling research-based reputation is important for business schools, the study places attention on further examination of determinants of impactful research as international accreditation only determines the growth of quantity not the quality.
