The previous volumes of the Studies in the Philosophy of Law appeared in Polish, in 2001 and 2003 respectively. The present, third volume introduces two novelties. The present, third volume introduces two novelties. First, it is published in English. Second, it has a monographic character, as its main topic are the various perspectives on the economic analysis of law. We would like to continue in this spirit and hope to publish the next volume on bioethical aspects of law, or bio-law. We would like to invite anyone interested in the subject and willing to contribute to cooperate with us. The present volume consists of twelve papers, written by colleagues form Poland, Germany, Belgium and Danmark. We would like to warmly thank them for their participation. The contributions cover various topics – from general legal-philospophical considerations, to more specific applications. The common background of the presented papers is that they all concern the economic analysis of law in its more less canonical form.
