"A major piece of work . . . a classic. There is no
other book like it."
--Norman Schofield, Washington University

"The authors succeed brilliantly in tackling a large
number of important questions concerning the
interaction among voters and elected representatives
in the political arena, using a common, rigorous
language."
--Antonio Merlo, University of Pennsylvania

Positive Political Theory II: Strategy and Structure
is the second volume in Jeffrey Banks and David
Austen-Smith's monumental study of the links
between individual preferences and collective choice.
The book focuses on representative systems, including
both elections and legislative decision-making
processes, clearly connecting individual preferences to
collective outcomes. This book is not a survey. Rather,
it is the coherent, cumulative result of the authors'
brilliant efforts to indirectly connect preferences to
collective choice through strategic behaviors such as
agenda-selection and voting.

The book will be an invaluable reference and teaching
tool for economists and political scientists, and an
essential companion to any scholar interested in the
latest theoretical advances in positive political theory.


Positive Political Theory I is concerned with the formal theory of preference aggregation for collective choice. The theory is developed as generally as possible, covering classes of aggregation methods that include such well-known examples as majority and unanimity rule and focusing in particular on the extent to which any aggregation method is assured to yield a set of best alternatives. The book is intended both as a contribution to the theory of collective choice and as a pedagogic tool.
