This paper describes how the Preisach model, with its superposition of hysteresis play operators, can be applied to economic systems. At the micro level economic agents, because of fixed or sunk costs of adjustment, adjust discontinuously to changes in state variables and have different trigger...

This paper elucidates hysteresis using a simple model of market entry and exit. A procedure for calculating hysteresis indices for economic time series is outlined. Some preliminary results assess the explanatory power of hysteresis variables in determining the equilibrium rate of unemployment...
