This book explores the behaviours that result from Public Service Motivation (PSM), outside of a firm or agency environment. Covering topics such as volunteering, and political participation, the authors present rich empirical data from the US and the UK, as well as other countries. With fresh insights into a growing area of interest, this book will provide valuable reading for researchers working in the field of PSM, and those involved in working towards a successful and sustainable society. “This book sets out not only to understand Public Service Motivation, but to find its place among other more traditional organisational research topics. In doing so, Homberg and Costello show that PSM is no longer in its infancy and can be successfully employed to tackle issues beyond public service.” (Davide Secchi, Director of the Centre for Computational and Organisational Cognition, University of Southern Denmark, Denmark) “This book sets out not only to understand Public Service Motivation, but to find its place among other more traditional organisational research topics.
