Neoclassical Equilibrium

Neoclassical equilibrium can be simply stated as the state when supply equals demand. Mathematically this can be thought of as a fixed point, which implies a rest point where things are not changing in the market. Thus, prices only change due to shifts that change the equilibrium.

Generally, disequilibrium is seen as boring or a state not worth studying since markets won’t clear, and nothing will be sold. @culp2011
