Motivated by a central banker with a symmetric inflation zone target, we assume in this letter that the loss function of a policy maker can be approximated by the quartic form. For non-normal distributions, we show that such a loss function implies a systematic inflation bias even when the bank...

Motivated by a central banker with a symmetric but non-quadratic loss function, we show in this note that the approximations of two plausible loss functions of this type will include a quartic term. For skewed distributions, we establish that such a loss function implies a systematic inflation...
