A central theme of this lively and accessible text is that theory helps us to understand policy, politics and practice. The book combines an in-depth exploration of selected theoretical perspectives and concepts with the student-friendly format of the Understanding Welfare series. The author uses diverse examples from contemporary social policy to help theoretical arguments come alive. It should provide a key text for 2nd and 3rd year undergraduates and postgraduates in social policy and related subjects, as well as their teachers.
