• (n.) A lagging or retardation of the effect, when the forces acting upon a body are changed, as if from velocity or internal friction; a temporary resistance to change from a condition previously induced, observed in magnetism, thermoelectricity, etc., on reversal of polarity.

1. The failure of an economic variable to return to its initial equilibrium after a temporary shock. For example, an industry or trade flow might disappear due to an exchange rate change, then not reappear after the change is reversed. 2. A time lag between a cause and an effect. (Though this seems to be the more standard dictionary definition, ec...

A property of physical and chemical systems that do not instantly follow the forces applied to them, but react slowly, or do not return completely to their original state. In the case of magnetic systems, when an external magnetic field is applied to a magnetic material, the material becomes magnetised absorbing some of the external field. When the...

In economics, hysteresis refers to the assumption that the present level of an economic variable depends on past levels. For example, when unemployment rises, a new classical economist would expect wages to fall and the demand for labour to rise, so that unemployment would quickly disappear. If there is hysteresis, however, this may not occur since...

hysteresis 1. A delayed response by an object to changes in the forces acting on it; especially, magnetic forces. 2. The lagging of an effect behind its cause, as when the change in magnetism of a body lags behind changes in the magnetic field. 3. A condition in which the state of a system depends on its previous history, generally the retardatio...
