Abstract

This paper examines the dynamic effects of consumption externalities in Bosi and Seegmuller (J Math Econ 46:475–492, 2010). We show that only the patient agent holds the entire capital stock at the steady state, while the impatient agent works to finance his consumption. Our main result states that consumption externalities represent the main mechanism that explains the emergence of endogenous fluctuations due to self-fulfilling expectations. Finally, consumption externalities promote the appearance of deterministic cycles of period two.
