Integral representation with convex capacities that are squeeze of (additive) probability measures
(Fundação Getulio Vargas. Escola de Pós-graduação em Economia, 2003-10-24)
In this paper I will investigate the conditions under which a convex capacity (or a non-additive probability which exhibts uncertainty aversion) can be represented as a squeeze of a(n) (additive) probability measure associate ...

Cournot competition under Knightian uncertainty
(Sociedade Brasileira de Econometria, 1998-11-02)
This article applies a theorem of Nash equilibrium under uncertainty (Dow & Werlang, 1994) to the classic Cournot model of oligopolistic competition. It shows, in particular, how one can map all Cournot-Nash equilibria ...
Oligopolistic competition under knightian uncertainty
(Escola de Pós-Graduação em Economia da FGV, 1996-07)
This artic/e applies a theorem of Nash equilibrium under uncertainty (Dow & Werlang, 1994) to the classic Coumot model of oligopolistic competition. It shows, in particular, how one can map all Coumot equilibrium (which ...
Nash equilibrium under knightian uncertainty: breaking down backward induction (extensively revised version)
(Escola de Pós-Graduação em Economia da FGV, 1993-04)
We define Nash equilibrium for two-person normal form games in the presence of uncertainty, in the sense of Knight(1921). We use the fonna1iution of uncertainty due to Schmeidler and Gilboa. We show tbat there exist Nash ...
The effects of ambiguity on entrepreneurship
(Wiley, 2020)
We incorporate ambiguity (Knightian uncertainty) into a classic model of entrepreneurship to analyze, among other things, its effects on the optimal level of business startups, the relation between total assets and the ...
General equilibrium, wariness and efficient bubbles
(Academic Press Inc Elsevier Science, 2011-05)
Wary consumers overlook gains but not losses in remote sets of dates or states. As preferences are upper but not lower Mackey semi-continuous, Bewley's (1972) [4] result on existence of equilibrium whose prices are not ...
Risk, ambiguity, and diversification
(Universidad del RosarioFacultad de Economía, 2016)
Attitudes toward risk influence the decision to diversify among uncertain options. Yet, because in most situations the options are ambiguous, attitudes toward ambiguity may also play an important role. I conduct a laboratory ...
Does uncertainty cause inertia in decision making? An experimental study of the role of regret aversion and indecisiveness
(Universidad del RosarioFacultad de Economía, 2016)
Previous research has shown that often there is clear inertia in individual decision making---that is, a tendency for decision makers to choose a status quo option. I conduct a laboratory experiment to investigate two ...
