This book critically examines the various approaches of tax systems in the U.K., the U.S., and Israel, in relation to the timing of the recognition of income and expense for tax purposes, and suggests an innovative new model of timing for tax purposes. 'Moshe Shekel has produced a prodigious piece of work on timing, the result of a major research project ... Few American practitioners, even in down economic times, can afford the time to write a comprehensive, comparative study, systematically pulling together the doctrine and the controversies about doctrine in three sophisticated jurisdictions - the United States, the United Kingdom, and Israel. But that comprehensive, comparative work is exactly what Shekel has given us.'- Erik M. Jensen, Columbia Journal of Tax Law, Vol. 1:262, 2010 "Overall, the book is a truly scholarly piece about the theory and practice of taxable income recognition. ... Thanks to Dr Shekel, the reader ends up attaining a better grasp of the corporate taxing environments in these countries." - Volkan Muslu, European Accounting Review, 2011
