Can boundedly rational agents survive competition with fully rational agents? The authors develop a highly nonlinear heterogeneous agents model with rational forward looking versus boundedly rational backward looking agents and evolving market shares depending on their relative performance....

We analyze the individual and macroeconomic impacts of heterogeneous expectations and action rules within an agent-based model populated by heterogeneous, interacting firms. Agents have to cope with a complex evolving economy characterized by deep uncertainty resulting from technical change,...

Firms strategically disclose product information in order to attract consumers, butrecipients often find it costly to process all of it, especially when products have complexfeatures. We study a model of competitive information disclosure by two senders, inwhich the receiver may garble each...

This paper derives two mechanisms through which Bayesian-rational individuals with differing priors will tend to be relatively overconfident about their estimates and predictions, in the sense of overestimating the precision of these estimates. The intuition behind one mechanism is slightly...

In this paper we develop a Hybrid Macroeconomic ABM. The economy is populated with firms heterogeneous in term of financial fragility, measured via the Equity Ratio. Firms are maximizing profit by choosing capital, which can not be raised on the stock market. Therefore they have to rely on a...
