Web28.1. Overview ¶. The McCall search model [ McC70] helped transform economists’ way of thinking about labor markets. To clarify vague notions such as “involuntary” unemployment, McCall modeled the decision problem of unemployed agents directly, in terms of factors such as. current and likely future wages. impatience. WebLet’s now step through these ideas more carefully. 43.2.2. Formal definition ¶. Formally, a discrete dynamic program consists of the following components: A finite set of states S = { 0, …, n − 1 } A finite set of feasible actions A ( s) for each state s ∈ S, and a corresponding set of feasible state-action pairs.
