Neutral equilibrium

Earlier work on FP auctions with known number of bidders indicated systematic overbidding compared to risk neutral equilibrium. Risk aversion has been suggested as one of the possible explanations for observed overbidding (Cox, Roberson, and Smith 1982).

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.

In physics, according to a definition in the Penguin Dictionary of Physics, "a body is in stable, unstable, or neutral equilibrium according to whether the forces brought into play following a slight displacement tend to decrease, increase, or not affect the displacement, respectively." Further, "in general, the potential energy of a system is at a minimum if it is stable or a maximum if it is unstable." The object of most associations, I would assume, would be to generate energy, perhaps maximum energy.
