It is pointed in the article that a significant and relevant direction of new social sciences in the body of the problems of research into welfare states (in general) and in Central and Eastern European countries in particular, could be the investigation of the problem of compatibility and coherence between welfare state models and public administration models, to be more precise, examining if this relation is accidental or not. This problem of coherence between welfare state and public administration models has to be investigated empirically in subsequent research, as the author raises this problem firstly in this article theoretically.
