Webt is what we call a state variable because it is the state that the decision-maker faces in period t. Note that x t is parametric (i.e., it is taken as given) to the decision-maker's problem in t, and x t+1 is parametric to the choices in period t+1. However, x t+1 is affected by the choices made in t. The state variables in a problem are those ...
