This article completes an axiomatic approach of utilities streams. The approach is more precisely based upon the robust pre-orders that open the scope for $\alpha$-MaxMin representations. A general $T$-steps Temporal Bias axiom is first introduced, that encapsulates stationarity and $1$-step...

This study adresses time-dependent orders that are shown to lead to recursive representations based upon a Max-Min dichotomy and introduce a structure that is naturally based upon time-varying multiple discounts. It is argued that this setup naturally provides an enriched understanding of the...
