4] By allowing the markets to adjust under conditions of multiple equilibria, the experiments explore whether the markets will adjust to an unstable equilibrium, and by making a n equilibrium unstable after the market has adjusted, the experiment determines the nature of the adjustment laws.
A feature of the unstable equilibria of mathematical/theoretical models is that small perturbations away from an unstable equilibrium will precipitate a series of movements away from that equilibrium and toward the nearest stable equilibrium.
then one can show that the stationary solution, [Mathematical Expression Omitted], will be the long-run price level of the economy Replacing the assumption of rational expectations with adaptive expectations affects the stability properties of the stationary solution, changing it from an unstable equilibrium to a stable one.

To understand and to analyze the stability of the entire human body it is important also to make a classification of equilibrium in: stable equilibrium occurs when an object is placed in such a position that any disturbance effort would raise its COM and tends to fall back in its original position; unstable equilibrium occurs when an object is placed in such a position that any disturbance effort would lower its COM and tends to fall into a more stable position; and neutral equilibrium occurs when an object is placed in such a position that any disturbance effort would not change the level of its COM and tends to fall into a more stable position.
