Abstrakt: In this research paper, we extend the model constructed by Gambacorta and Signoretti (2014) by introducing an occasionally binding credit constraint based on a penalty function approach in line with Brzoza-Brzezina, Kolasa, and Makarski (2015) to study the performance of the Taylor rule augmented with asset prices. First, we compare the properties of the baseline model and its modified version. Then, we use both models to study the performance of the basic and extended Taylor rule. The performance of Taylor rules is examined under the optimisation of a central bank's loss function and the welfare maximisation of economic agents. The analysis delivers the following results. The model with an occasionally binding credit constraint has more favourable properties regarding the hump-shaped and asymmetric impulse responses compared to an eternally binding credit constraint model. The best rule regarding the lowest value of the central banks' loss function proves to be the rule augmented with asset prices. The optimal reactions are, however, shock- and model-dependent, and therefore, any rule-like behaviour does not seem to be appropriate. The welfare maximisation under the occasionally binding credit constraint model reveals that reacting to asset prices might not be welfare-improving for both types of economic agents – households and entrepreneurs. This result is in contradiction with the implications achieved under the eternally binding credit constraint model.
