Now that the late 1970s debate in the U.S. about the policy questions involved in "integrating" the corporate income tax with the individual shareholder income tax has quieted, and the activity in many nations to adopt some form of integration has slowed, it seems time for a good, reflective and technically masterful book on the subject. Such a book would be especially appealing if it took a comparative perspective and drew on the knowledge and experience of other highly developed economies and income tax systems. Appearing to be such a book is the volume by Martin Norr, The Taxation of Corporations and Shareholders.** This valuable book, another in the series done in the International Tax Program of the Harvard Law School, has many virtues, of which-as with so many books-one or two are also its vices. Moreover, it needs one very important warning on its label. The warning should announce that this 1982 copyrighted book is really a 1977 book, and it consequently lacks a description of more recent developments in the law and analysis of the integration problem. Even though some recent literature (up to 1981) is cited in the footnotes and excellent bibliography,1 the text in effect stops in 1977, for reasons of misfortune. The named author, Martin Norr, completed a draft of this study but had not revised it when he died in 1972.2 Others pitched in, especially Prof. Elizabeth Owens (Director of Research at the International Tax Program), who supervised a third year Harvard Law student, Christopher A. Klein, while he updated the manuscript to 1977, Professor Hugh Ault of Boston College Law School (whose Appendix, excerpted from his article, covers the 1977 German integration system), Prof. Richard M. Bird of Toronto, and far from least, Mr. Mitsuo Sato, of the Ministry of Finance in Japan. These collaborators have largely completed and updated the book to 1977, and-spottily-later.3 Allowing for the fact that it does not cover some important recent developments in the U.S. and elsewhere, a few of which will be mentioned below, the reader will find this book to have many
