A portfolio-based evaluation of affine term structure models

Andrea Beltratti, Paolo Colla
2006 Annals of Operations Research  
Each quarter the optimizer selects the optimal portfolio, and the sequence of optimal portfolios is then evaluated in terms of financial properties.  ...  Starting from the conditional moments of the state vector implied by the models, we introduce binomial approximations to come up with discrete scenarios for the future state variables.  ...  The optimizer selects the optimal portfolio each quarter of our sample period.  ...
