Defining and Modeling State-Dependent Dynamic Systems
Keyword(s):
A state-dependent dynamic system is one in which (1) the marginal effect ofxonyat timet() depends on the prior value of the dependent variable, and (2) the persistence of the dependent variable () depends onxt. We present a methodological strategy for dealing with state-dependent dynamic systems and demonstrate the consequences of ignoring state-dependence. As an applied example, we find evidence of state-dependence in the relationship between presidential approval and economic performance: high unemployment rates are most damaging to presidential approval among presidents with the highest initial approval ratings.
