In August 1976 the research seminar 'Decision-making in business' was organized at Nijenrode, The Netherlands School of Business. More than fifty scientists and practitioners from nine countries presented research papers in one of the six discussion groups. Some ofthem also presented some of their ideas in front of a large mixed audience at a one-day symposium. Many of the papers presented at Nijenrode were of such a high quality that the decision to publish a selection of them was an easy one. At the same time the new series Nijenrode studies in business was initiated. All who were involved, the policy committee 'Of the Nijenrode studies, the advisory and editorial board of the series, the publisher, and the organizing committee of the seminar and symposium, acclaimed the idea of publishing three volumes in the new series. A collection of eleven papers could be grouped under the title Trends in managerial andfinancial accounting, and has been published as volume 1 of this series. A collection of fourteen papers has been published as the second volume under the title Trends in financial decision- making, while this volume, consisting of twelve papers (and an introduction) explores the theme Trends in business ethics. The introduction by Stanley L. Jakiwas written for the symposium. It suggests why the papers of Pjotr Hesseling, Antoine Kreykamp, and Richard H. Viola, which were t presented at Nijenrode, are introduced here.
