Error Correction Model and Stable Equilibrium

[learner]

Dear All

In the Error Correction Model, if the ECM(-1) is negative and less than one, we interpret that this is speed of convergence and process will converge to stable equilibrium value.

What do we mean by "Stable Equilibrium"? for instance, if the study is about Determinants of Crime and one says that stable equilibrium will be achieved as shown by the value of ECM(-1). Does it mean zero crime, mean level of crime or what??

You can also refer to a book or article that what exactly this "convergence to stable equilibrium" means.

Thanking you advance.
