| Abstract: | This paper seeks to shed light on the inflation dynamics of four new central European EU members: the Czech Republic, Hungary, Poland, and Slovakia. To this end, the New Keynesian Phillips curve augmented for open economies is estimated and additional statistical tests applied, with the following results: (1) the claim of New Keynesians that the real marginal cost is the main inflation-forcing variable is fragile, (2) inflation seems to be driven by external factors, and (3) although inflation holds a forward-looking component, the backward-looking component is substantial. An intuitive explanation for higher inflation persistence may be adaptive, rather than rational price setting of local firms. |
