Among non Exponential Discounting (ED) models, introduced to capture time inconsistent choices, Hyperbolic Discounting (HD) recently gained particular relevance. This paper points out that, for some particular payoff structures, HD can also represent consistent preferences

The paper shows that in a Prisoner’s Dilemma Knightian uncertainty, formalised by multiple priors, may entail cooperation at a generalised Nash Equilibrium. The main idea is that players may have an attitude towards uncertainty that depends upon their available strategies. In particular, if...

In the economic literature the most widely used type of additive time discounting is Exponential Discounting. Recent work however casts doubts on its ability in explaining how individuals effectively choose. In particular a more general form of discounting that gained importance, in both applied...

In a stimulating paper Piccione and Rubinstein (1997) argued how a decision maker could undertake dynamically inconsistent choices when, in an extensive form decision problem, she exhibits a particular type of imperfect recall named absentmindedness. Such imperfection obtains whenever an...
