Chiaki Hara et al., « Efficient Allocations under Ambiguous Model Uncertainty », HAL SHS (Sciences de l’Homme et de la Société), ID : 10670/1.0db508...
We investigate consequences of ambiguity on efficient allocations in an exchange economy. Ambiguity is embodied in the model uncertainty perceived by the consumers: they are unsure what would be the appropriate probability measure to apply to evaluate consumption and keep in consideration a set P of alternative probabilistic laws. Consumers are heterogeneously ambiguity averse with smooth
