We consider a linear factor APT model and assume that agents are ambiguity averse with respect to payoffs of arbitrage portfolios. In contrast to the standard result, pricing errors need not converge to zero in the limit as the number of assets goes to infinity. Even in the case of exact factor...

We explicitly derive and explore the optimal consumption and portfolio policies of a loss- averse individual who endogenously updates his reference level over time. We find that he protects his current consumption by delaying painful reductions in consumption after a drop in wealth, and...
