This paper analyses optimal monetary policy and welfare implications of three endogenous processes in forming inflation expectations, which depart from the standard case of rational expectations. Two processes assume heterogeneous expectations driven either by discretionary central banks through...

Diagnostic expectations constitute a realistic behavioral model of inference. This paper shows that this approach for expectation formation can be productively integrated into the New Keynesian framework. To this end, we start by offering a first technical treatment of diagnostic expectations in...

We review and evaluate methods previously adopted in the applied literature of adaptive learning in order to initialize agents' beliefs. Previous methods are classified into three broad classes: equilibrium-related, training sample-based, and estimation-based. We conduct several simulations...

We study the impact of diverse beliefs on conduct of monetary policy. Individual belief is modeled by a state variable that defines an individual's perceived laws of motion. We use a New Keynesian Model that is solved with a quadratic approximation hence individual decisions are quadratic...
