A new approach to the derivation of asset price bounds

In a two-period setup we develop a generalization of good-deal bounds that allows to include in the problem the implications of asset pricing models. Our basis is the distance behind Hansen and Jagannathan's measure of model misspecification since a volatility constraint on the stochastic discount factor is a particular case of a restriction on this distance. We also present an alternative approach which mostly retains the economic interpretation underlying the above extension and it has a very useful property since the resulting bounds can be computed by simply solving a linear program.
