Written by leading scholars from various disciplines, this book presents current research on topics such as public choice, game theory, and political economy. It features contributions on fundamental, methodological, and empirical issues around the concepts of power and responsibility that strive to bridge the gap between different disciplinary approaches. The contributions fall into roughly four sub-disciplines: voting and voting power, public economics and politics, economics and philosophy, as well as labor economics. On the occasion of his 75th birthday, this book is written in honor of Manfred J. Holler, an economist by training and profession whose work as a guiding light has helped advance our understanding of the interdisciplinary connections of concepts of power and responsibility. He has written many articles and books on game theory, and worked extensively on questions of labor economics, politics, and philosophy.
