as a field whose practitioners share some general commitments and whose boundaries
remain fuzzy. Public choice is a part of the more general fields of law and economics or
of political science. It has affinities and overlaps with fields that use different labels, such
as `social choice' and it is difficult to distinguish from the work of those who style them-
selves as contributors to positive political theory, but who would not necessarily identify
themselves as public choice theorists.

rational self-interest. And they all seek to understand what types of decisions and legal
arrangements will emerge from the interactions of individual or organizational prefer-
