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...

When there are competing technologies or products with unknown payoffs an important question is which technology will prevail and whether technologies with different payoffs can coexist in the long run. In this paper, we use a social learning model with local interactions to study this question....
