Abstract: We provide several types of central banker's preferences according to their monetary policy choices. Although not exhaustive, our list covers from extreme (conservative and populist) to moderate behaviours, such that it is flexible in relation to the degree of conservativeness, as well as in relation to monetary regimes. We also use the traditional axiomatic approach for utility representation in order to investigate which of those preferences admit numerical representation. Our main finding states that so called stabiliser central bank is the only that admits representation through utility. Nevertheless, we show that even preferences without utility representation may be useful as alternatives for studies which propose different types of central bank.
