Gift authorship: Look the gift horse in the mouth.

Unmerited authorship in research papers is widely acknowledged to constitute research misconduct. In different contexts, it has been called "gift", "honorary", or "guest" authorship. Although several attempts have been made to address the issue, it remains a significant problem in research. In this paper, we discuss accepted criteria that qualify a person to be an author on a research publication and define what constitutes "gift authorship". We also look at the scenario in India and try to identify the circumstances that have fostered this practice in academia in the country. Finally, we discuss the adverse effects of this practice on the research enterprise as a whole, and possible remedial measures.
