Most studies of optimal monetary policy under learning rely on optimality conditions derived for the case when agents …, and makes active use of, the learning algorithm agents follow in forming their expectations. In this setup, monetary … policy can influence future expectations through its e ect on learning dynamics, introducing an additional tradeo between …

We derive optimal monetary policy in a sticky price model when private agents follow adaptive learning. We show that … order to facilitate private sector learning and thus ease the future intratemporal inflation-output gap trade-offs. The … policy recommendation is robust: the welfare loss entailed by optimal policy under learning if the private sector actually …

In this study we consider a linear model with forecast feedback in which boundedly rational agents are learning the … parameter values of the rational expectations equilibrium by the OLS learning procedure. We show strong consistency of the OLS … boundedly rational learning approach to models including non-stationary time series, like processes with polynomial trends or …

macroeconomic models in which agents are boundedly rational and use an adaptive learning rule to form expectations of the endogenous … estimate it empirically. Two prominent learning algorithms are considered, namely constant gain and decreasing gain learning …. For each of the two learning rules, the analysis proceeds in two stages. First, the paper derives the asymptotic …

This survey discusses behavioral and experimental macroeconomics emphasizing a complex systems perspective. The economy consists of boundedly rational heterogeneous agents who do not fully understand their complex environment and use simple decision heuristics. Central to our survey is the...

Forward-looking RE models such as the popular New Keynesian (NK) model do not provide a unique prediction about how the model economy behaves. We need some mechanism that ensures determinacy. McCallum (2011) says it is not needed because models are learnable only with the determinate solution...

Adaptive learning under constant-gain allows persistent deviations of beliefs from equilibrium so as to more … learning estimates for a general class of dynamic macroeconomic models under constant-gain learning. Our approximation provides … renewed convergence conditions that depend on the learning gain and the model's structural parameters. We validate the …
