This book offers, for the first time, a systematic, ethical, and economic foundation of financial ethics. It is aimed at economists (advanced students, educators, and reflective practitioners). An introduction to financial ethics is provided, supplemented by two concrete reflections on current challenges in financial market policy. Additionally, two chapters present the institutions of finance, their functioning, and their overall economic significance. Thus, ethicists, social scientists, and others interested in financial market policy also receive a comprehensible introduction to financial ethics and its economic foundations.
