Saddlepath learning occurs when agents know the form but not the coefficients of the sad?dlepath relationship defining … rational expectations equilibrium. Under saddlepath learning, we obtain a completely general relationship between determinacy … system is determinate, we show that a learning process based on the saddlepath is always e-stable.

We show that for many classes of symmetric two-player games, the simple decision rule "imitate-the-best" can hardly be beaten by any other decision rule. We provide necessary and sufficient conditions for imitation to be unbeatable in the sense that, even against a very clever opponent,...

We analyze a symmetric n-firm Cournot oligopoly with a heterogeneous population of optimizers and imitators. Imitators mimic the output decision of the most successful firms of the previous round a la Vega-Redondo (1997). Optimizers play a myopic best response to the opponents' previous output....

We test whether subjects try to influence those … and that all learning algorithms are subject to exploitation with the notable exception of imitation. The experiment was …

We introduce learning into a Hotelling model of a non-renewable resource market. Bycombining learning and scarcity we … add signi?cantly to the dynamics implied by learning and substantially enhance the volatility of commodity prices. In our … learning model we show how a self con?rming equilibrium exists but is not constant over time. As scarcity increases the SCE …

Saddlepath learning occurs when agents learn adaptively using a perceived law of motion that has the same form as the … saddlepath relationship in rational expectations equilibrium.  Under saddlepath learning, we obtain a completely general … information.  When the system is determinate, we show that a learning process based on the saddlepath is always e-stable.  When …

We show that for many classes of symmetric two-player games, the simple decision rule “imitate-if-better” can hardly be beaten by any strategy. We provide necessary and sufficient conditions for imitation to be unbeatable in the sense that there is no strategy that can exploit imitation as a...
