Then pt+1 (L) = pt (L)+λ(1− pt (L)), where λ ∈ (0, 1] is the speed of learning. Thus, given positive feedback, pt+1 (L) must exceed pt (L) [unless pt (L) already equals 1]. Unlike satisficing, however, positive feedback need not drive the propensity to use L all the way to 1; instead, how much it increases depends on a parameter—the speed of adjustment, λ. Similarly, if the agent tries L today and it fails, then pt+1 (L) = pt (L) − λpt (L). Thus, given negative feedback, pt+1 (L) must be less than pt (L).

Bounded Rationality and Elections • 21 not one of its fundamental premises. As the Simon-March point on problem-editing makes clear, what is central to the program is a claim that humans use some method of reducing a complex problem to a cognitively manageable one.

Aspirations: ai,t , a number on the real line, is i’s aspiration in date t. If aspirations are exogenously fixed, then agent i’s aspiration is denoted by ai , which is independent of time. 3. Payoffs: πi,t is i’s payoff in date t. If payoff distributions have compact (bounded and closed) supports, then the minimal payoff of player i is denoted by π i and π i is her maximal payoff.
