In a preceding companion paper, a static model of individual decision making was proposed that, due to imprecise perceptions, induces simple and inertial behavior at equilibrium ("status-quo optimal") points. This paper addresses two complementary issues. Firstly, it studies the learning...

The paper studies a model of accumulation and growth where a continuum of heterogeneous firms play dynamically optimal strategies along a (rational expectations) equilibrium. The key feature of the model is that firms' technological decisions are assumed subject to both friction and external...

Simplicity and inertial (or status-quo) bias are common features of actual decision rules used by real-life agents. In this paper, we provide one possible rationale for these features in terms of a model in which the decision maker is subject to imprecise perceptions about the consequences of...

This paper analyzes an exchange economy in which several assets serve as stores of value and where agents have completely heterogeneous preferences and endowments. It describes the set of perfect foresight equilibria in which all assets have positive prices. There are international policies with...
