RT Article T1 Co-offending as social exchange. Explaining characteristics of co-offending JF The British journal of criminology VO 43 IS 2 SP 398 OP 416 A1 Weerman, Frank M. 1968- A2 O'Sullivan, Eoin LA English YR 2003 UL https://krimdok.uni-tuebingen.de/Record/1639316159 AB Studies in the past have already revealed some interesting characteristics of co-offending, but relatively little attention has been paid to explaining them.

The basic concepts of such a social exchange theory are formulated in this article, and a causal model based on this theory is deduced. The paper also shows how the proposed theory may explain the well-known characteristics of co-offending K1 Gruppendelinquenz K1 Mittäterschaft K1 Austauschtheorie
