neutral equilibrium

[′nü·trəl ‚ē·kwə′lib·rē·əm]
(physics)
A property of the steady state of a system which exhibits neither instability nor stability according to the particular criterion under consideration; a disturbance introduced into such an equilibrium will thus be neither amplified nor damped. Also known as indifferent equilibrium.

neutral stability

neutral stability
Neutral stability.
i. In meteorology, it is that condition in which the observed lapse rate is equal to the dry adiabatic lapse rate. A parcel of dry air will remain at its new level once it is pushed up because its temperature will be the same as that of the surrounding air.
ii. In aerodynamics, it means that an aircraft will tend to stay in its most recently commanded attitude or condition, without oscillations, and it will neither tend to return to its previous state or diverge from its new attitude. Also called neutral equilibrium or neutral static stability.

Cox, Roberson, and Smith (1982) and Cox, Smith, and Walker (1988) reported heterogeneous bidding above risk neutral equilibrium in FP auctions for mechanisms with fixed number of bidders and Palfrey and Pevnitskaya (2008) for auctions with endogenous entry, where the number of bidders was known at the time of submitting a bid.
Figures 1A and 1B display graphs of the risk neutral equilibrium bidding function in the FP auction, [[beta].
In the FP auction we use bidder i's predicted risk neutral equilibrium bid for item k in period t.
Previous theoretical work in this environment identified the dominant strategy in the SP auctions and risk neutral equilibrium model in the FP auctions, which we adapted to our experimental design.
