(N.S.) 2, No. 2, 29-33 (2008). Summary: Informational and metastrategic extensions – metagames – of lexicographic finite noncooperative games are discussed in this paper. It is proved that there always exists an equilibrium situation in the first metagames. According to an example it is shown that in the metaextensions there exists a situation which is at the same time equilibrium and Pareto optimal.
