Business ethics as a field of teaching and research has expanded and diversified tremendously over the last decade. The new research spans a large diversity of fields: corporate governance, corporate responsibility, citizenship, financial ethics, HR, international management, leadership, virtues, religion, SME’s, values based management, marketing, to name but a few. Business ethics has also turned into an interdisciplinary field, without however losing its philosophical foundation. The International Handbooks in Business Ethics series identifies crucial areas in business ethics research and dedicates a handbook to it. It will draw upon the leading international scholars in each field and reflect the diversity in research methods. Each multivolume handbook contains the fundamental questions being posed, reflects the state of the art of the research at this moment as well as the most important research results over the past decade. In this we cover what has been learned as well as the major challenges we face for the future. Topics in this series are identified from discussions with leading scholars. Each Handbook will be directed and compiled by a handbook editor working in close cooperation with the series editor to ensure the appropriateness of the contributions as well as the consistency over the series volumes. The Handbooks will be published in both print and electronic versions.
