This rigorous yet lucid book is concerned with the analysis of tax design and the problems involved in choosing a tax and transfer structure. John Creedy discusses fundamental problems which are then illustrated using relatively simple models. Following a comprehensive introduction, part II is concerned with the link between economic theory and tax policy, and considers why it is so difficult to design a tax and transfer structure that receives widespread support. Part III explores particular types of tax and transfer structure, and alternative approaches to the choice of tax rates within these systems. Part IV examines tax revenue and its variations, including the concepts of tax revenue elasticity and the elasticity of taxable income, whilst part V offers an examination of two wide-ranging reviews of tax structures. The author argues that economists can make a valuable contribution to rational policy debate by clarifying the nature of the interdependencies and relationships involved. This comprehensive book will appeal to researchers and graduate students in public finance, public economics and taxation, as well as economists in governmental departments and international organisations.
