This paper puts forth a concept of Adptivety Rational Equilibrium (A.R.E) where agents base decisions upon predictions of future values of endogenous variables whose actual values are determined by equilibrium equations.

In this paper we obtain bounds under weaker nonparametric assumptions and explore how the bounds with assumptions imposed.
