	In [[economics]], '''''hysteresis''''' refers to the possibility that periods of high [[unemployment]] tend to increase the rate of unemployment below which inflation begins to accelerate, commonly referred to as the [[natural rate of unemployment]] or non-accelerating inflation rate of unemployment ([[NAIRU]]). The term is based on the physical phenomenon of [[hysteresis]] in [[magnetism\|magnetic]] materials.

	~~If the unemployment rate exhibits hysteresis, then it follows a statistically [[stationary process\|non-stationary process]], because the [[expected value]] of the unemployment rate now~~ and in the ~~future permanently shifts when the rate itself changes~~. ~~The process with hysteresis is a [[unit root]] process, which in its simplest form can~~ be ~~characterized as~~

	~~:<math>U_t = U_{t-1} + e_t~~,~~</math>~~

	~~where <math>U_t</math> is~~ the ~~unemployment rate at time ''t''~~ and ~~<math>e_t</math> is a stationary error term representing outside shocks to the rate~~. ~~According to this characterization, <math>E_{t~~-~~1}(U_{t+\tau}) = U_{t~~-~~1}</math>~~ for ~~all <math>\tau = 0, 1, \ldots</math>, where~~ <~~math~~>~~E_{t-1}~~<~~/math~~> ~~refers~~ to ~~an expectation conditional on values observed no later than time ''t''–1; any temporary shock~~ to ~~unemployment~~, ~~represented by a single non-zero value of <math>e_t</math>, results in a permanent change~~ to ~~expected unemployment (even for <math>\tau</math> indefinitely large so the expectation~~ is ~~for indefinitely far into~~ the ~~future). A more elaborate model would allow <math>E_{t-1}(U_{t+\tau})</math>~~ to ~~go up positively but less than one-for-one with <math>e_t</math>~~. ~~In contrast~~, ~~a non-hysteresis model~~ of ~~unemployment would have <math>U_t</math> following a stationary process~~, so that <~~math~~>~~E_{t-1}U_{t+\tau}~~<~~/math~~> for ~~arbitrarily large <math>\tau</math> would always equal a permanently fixed natural rate of unemployment.~~

	~~==Causes==~~

	~~When some negative shock reduces employment in a company or industry~~, ~~there are fewer employed workers left. As the [[insider-outsider theory of employment\|employed workers]] usually have the power to influence or set wages~~, ~~their reduced number incentivizes them to bargain for even higher wages when the economy again gets better~~, ~~instead~~ of ~~letting the wage stay at the [[equilibrium wage]] level~~, ~~where the supply~~ and ~~demand of workers would match.

	~~==Policy implications==~~

	~~If there~~ is ~~no hysteresis~~ in ~~unemployment, then for example if the [[central bank]] wishes to lower the [[inflation\|inflation rate]] it may shift to~~ a ~~contractionary [[monetary policy]], which if not fully anticipated~~ and ~~believed will temporarily increase the unemployment rate; if~~ the ~~contractionary policy persists, the unemployment rise will eventually disappear as the unemployment rate returns~~ to ~~the natural rate~~. ~~Then~~ the ~~cost~~ of ~~the anti-inflation policy will have been temporary unemployment~~. ~~But if there is hysteresis~~, the ~~unemployment rise initiated by the contractionary policy will never completely go away,~~ and ~~in this case the cost~~ of the ~~anti-inflation policy will~~ have ~~been permanently higher unemployment, making the policy less likely to~~ have ~~greater benefits than costs~~.

The term is based on the physical phenomenon of [[hysteresis]] in [[magnetism\|magnetic]] materials.

			==Implication for statistical characterization of unemployment==

			If the unemployment rate exhibits hysteresis, then it follows a statistically [[stationary process\|non-stationary process]], because the [[expected value]] of the unemployment rate now and in the future permanently shifts when the rate itself changes. The process with hysteresis is a [[unit root]] process, which in its simplest form can be characterized as

			:<math>U_t = U_{t-1} + e_t,</math>

			where <math>U_t</math> is the unemployment rate at time ''t'' and <math>e_t</math> is a stationary error term representing outside shocks to the rate. According to this characterization, <math>E_{t-1}(U_{t+\tau}) = U_{t-1}</math> for all <math>\tau = 0, 1, \ldots</math>, where <math>E_{t-1}</math> refers to an expectation conditional on values observed no later than time ''t''–1; any temporary shock to unemployment, represented by a single non-zero value of <math>e_t</math>, results in a permanent change to expected unemployment (even for <math>\tau</math> indefinitely large so the expectation is for indefinitely far into the future). A more elaborate model would allow <math>E_{t-1}(U_{t+\tau})</math> to go up positively but less than one-for-one with <math>e_t</math>. In contrast, a non-hysteresis model of unemployment would have <math>U_t</math> following a stationary process, so that <math>E_{t-1}U_{t+\tau}</math> for arbitrarily large <math>\tau</math> would always equal a permanently fixed natural rate of unemployment.

			==Causes==

			When some negative shock reduces employment in a company or industry, there are fewer employed workers left. As the [[insider-outsider theory of employment\|employed workers]] usually have the power to influence or set wages, their reduced number incentivizes them to bargain for even higher wages when the economy again gets better, instead of letting the wage stay at the [[equilibrium wage]] level, where the supply and demand of workers would match.
