The topics include individual and collective rationality, motivation and intention in economics, coercion, public goods, climate change, and voting theory. The book offers an excellent overview over latest research in these fields.

Finally, we would like to mention that it has been a great pleasure and privilege for us to edit this volume, which is intended to be a tribute to Kotaro Suzumura's - mense intellectual contributions, especially in the theory of rational choice, welfare economics, and the theory of social choice.
