Sažetak
Green banking has become dominant in academics’ and practitioners’
discourse. The purpose of the research is to investigate
whether banks’ attitudes, in deciding to go green, change under
the influence of other banks through their mutual interaction and
whether hysteresis plays a part in the process. A mathematical
model, described by a differential system with time delay, considering
three variables, i.e.: green, outsider and undecided banks, is
used as a research method. We investigate the local stability of
the two equilibrium points. Moreover, we look for the optimal
control strategy targeting the undecided banks so that the outsiders’
group diminishes. The main contribution is that the paper
sheds more light on the qualitative rather than on the quantitative
side of the banking business given that banks’ behaviours are
examined when it comes to implementing green policies. The
research has policy implications since bank managers can decide
whether to follow the greening trends of other banks and bank
regulators can use the instrument for tracking the overall changes
in banks’ behaviours in this respect.
