Two major journals are published under the auspices of the PSS(I):
Both are high quality inter-disciplinary journals containing scientific papers on such topics as international conflict, arms races, the
effect of international trade on political interactions, defense expenditures, foreign policy decision making, international mediation, and
game theoretic approaches to conflict and cooperation. Members of the Society automatically receive issues of CMPS and may subscribe at a
reduced rate to the JCR. Members also have access to CMPS and JCR via the web.
