The paper studies learning with data (quasi-)differencing where agents need to (quasi-)difference data and then use an otherwise standard least squares learning procedure. It (1) establishes that the E-stability Principle is still valid for analyzing the convergence of the learning with (quasi-)...

A striking implication of the replacement of adaptive expectations by Rational Expectations was the "Lucas Critique," which showed that expectation parameters, and endogenous variable dynamics, depend on policy parameters. We consider this issue from the vantage point of a bounded rationality,...
