The traditional model of science knowledge dissemination and academic journal publishing is ＂pay-to-read＂. Users read and use journal papers via subscription of journals and databases. This model overtime enables major publishers to dominate the industry. Constantly facing subscription fee hikes, the academics has thus developed an open access model, one that is ＂pay-to-publish＂ and allows free use of published papers by anyone who is interested. Despite the positive intention, the new model opens an opportunity for publishers and journals that are interested solely in making profit. Naturally, it results in predatory open access (POA) and pseudo-science. This study first outlines the evolution of open access and introduces POA in terms of its operations, quality, users, and fees. Second, it presents the common characteristics of POA in business and management and the impact of such publishing as well as how business scholars in Taiwan have involved in POA. Third, it addresses the current status of journal whitelists and blacklists and their limitations. In the final section, this study makes suggestions specifically for individual researchers, doctoral program directors, university administrators, and the Ministry of Education in a hope to minimize the contamination of POA on academic research and appraisal system.
