The book sets out the array of problems in previous work on state failure with respect to conceptualization and definition, as well as how the causes and consequences of state failure have been addressed, and presents analyses to deal with these problems. Any analysis of state failure can be seen as an exercise in policy evaluation; this book undertakes the theoretical, conceptual, and analytic work that must be done before we can evaluate—or have much confidence in—both current and proposed policy prescriptions to prevent or manage state collapse.
