This concise introduction to the economic theories of taxation is
intuitive yet rigorous, relating the theories both to existing tax systems and to key
empirical studies.
The Economics of Taxation offers a thorough discussion of the consequences of
taxes on economic decisions and equilibrium outcomes, as well as useful insights into how
policy makers should design taxes. It covers such issues of central policy importance as
taxation of income from capital, environmental taxation, and tax credits for low-income
families. This second edition has been significantly revised and updated. Changes include
a substantially rewritten chapter on direct taxation; a discussion of recent research in
the chapter on mixed taxation; the replacement of the chapter on capital taxation with a
chapter on the "new dynamic public finance"; and considerations of environmental
taxation in both theory and policy chapters. The book is aimed at graduate students or
advanced undergraduates taking public finance classes as well as economists who want to
learn more about the topic. It combines discussion of theory, empirical work, and policy
objectives in compact form.
Appendixes provide necessary background material on consumer and producer theory and
the theory of optimal control.
