Homo Oeconomicus (HOEC) started life in 1983 as a German language occasional series concerned with various aspects of the theoretical and behavioral concept of homo economicus and its application in economics, philosophy, political science, and sociology. In 1995 it became a quarterly journal and in 1998 was fully internationalized with articles being exclusively in English. Since then Homo Oeconomicus has become an outlet for researchers working in the field of political economy, and a huge number of important papers have been published in the journal. From 2016 onward, Homo Oeconomicus is published by Springer. The journal will benefit from the modern technology and large distribution of an international publisher. We are proud to present the first issue of Homo Oeconomicus after its relaunch in early 2016.
