(2016) “Exuberance and Social Contagion.” Economics Bulletin, vol. 36, issue 3, pp. 1705-1714.http://hdl.handle.net/10400.21/6895Episodes of collective exuberance that recurrently hit the economy are, in this note, associated with sentiment propagation in a network of social relations. The pivotal role played by exuberant individuals will give place to a dynamic setting where limit cycles constitute the most plausible long-term outcome. Endogenous sentiment waves, with peaks and troughs of exuberance, are in this way identified in the context of a straightforward interaction scenario.engjournal article
