The paper undertakes a detailed characterization of the local dynamic properties of three simple deterministic models involving expectations. The expectations are formed under an adaptive learning process. Allowing for different degrees of learning quality, the analysis reveals the existence of...

The paper develops a simple Solow-like growth model, with two independent geographical spaces, where migration is possible and it is stimulated by wage differences. The model assumes a congestion externality: high concentration of individual agents in one of the economic spaces implies losses in...

The sticky-information model appeared in order to offer a more empirically consistent view on the effects of monetary policy than the one provided by the benchmark sticky prices setup. Such inattentiveness framework was built on the assumption that current decisions are mainly based on past...

Recent literature on individual decision-making emphasizes the idea that the brain functions as an organization, with the allocation of resources to the development of different cognitive tasks occurring via an agency relation across distinct brain systems. In this note, the mentioned view on...

A local stability condition for the standard neo-classical Ramsey growth model is derived. The proposed setting is deterministic, defined in discrete time and expectations are formed through adaptive learning. The stability condition imposes an upper bound on the long-term value of the gain...

We assume an environment where the current value of an aggregate nonstationary variable is generated by weighting the behavior of a large set of agents who choose to form expectations resorting to more or less outdated information concerning the state of the economy. Agents using recent...

It is common to recognize that ideas, technology and information disseminate across the economy following some kind of diffusion pattern. Typically, the process of adopting a new piece of knowledge will be translated into an s-shaped trajectory for the adoption rate. This type of process of...
