This paper by using error correction (EC) methodology, along with Chow stability tests, examines whether three cases of policy announcements in Greece, over the 1975-1995 period, have been considered credible or not by the public. Focusing on the Phillips curve trade-off, the empirical findings reveal that two out of three policy announcements are characterized as credible by private agents.
