We review some 30 years of academic research on corporate philanthropy, taking stock of the current state of research about this rising practice and identifying gaps and puzzles that deserve further investigation. To do so, we examine a total of 162 academic papers in the fields of management, economics, sociology, and public policy, and analyze their content in a systematic fashion. We distinguish four main lines of inquiry within the literature: the essence of corporate philanthropy, its different drivers, the way (...) it is organized, and its likely outcomes. After reviewing the main findings of the literature, we build on several research gaps to highlight directions for future research on corporate philanthropy with an interest in strengthening our understanding of this fascinating phenomenon at the crossroads of business and society.
