My Curriculum Vitae
One more new paper, joint with Paolo Ghirardato, on Risk Sharing in the Small and in the Large. This is a contribution to the literature on risk sharing / no betting under ambiguity, but we do not assume convexity of preferences. Get it from the Manuscripts section below.
Slightly older news:
Inching ever closer to completion: a paper on the foundations of sequential rationality. Decision theory meets game theory, with some results having implications for experimental economics as well. Stay tuned!
Ambiguity in the small and in the large (former title: "A more robust definition of multiple priors"). Econometrica, forthcoming (final version June 2012).
Supplemental appendix with an axiomatization of locally Lipschitz and "nice" preferences, plus additional results.

Recursive Vector Expected Utility; Preliminary version, May 2010. Comments welcome!
Abstract. This paper proposes and axiomatizes a recursive version of the vector expected utility (VEU) decision model (Siniscalchi, 2009). Recursive VEU preferences are dynamically consistent and ``consequentialist.'' Dynamic consistency implies standard Bayesian updating of the baseline (reference) prior in the VEU representation, but imposes no constraint on the adjustment functions and one-step-ahead adjustment factors. This delivers both tractability and flexibility. Recursive VEU preferences are also consistent with a dynamic, i.e. intertemporal extension of atemporal VEU preferences. Dynamic consistency is characterized by a time-separability property of adjustments---the VEU counterpart of Epstein and Schneider (2003)'s rectangularity for multiple priors. A simple exchangeability axiom ensures that the baseline prior admits a representation a la de Finetti, as an integral of i.i.d. product measures with respect to a unique probability µ. Jointly with dynamic consistency, the same axiom also implies that µ is updated via Bayes' Rule to provide an analogous representation of baseline posteriors. Finally, an application to a dynamic economy a la Lucas (1978) is sketched.
Additional Material for Vector Expected Utility...
December 2007 version; contains an alternative formulation and additional results.
Machina's Reflection Example and VEU Preferences: a Very Short Note. Shows that VEU preferences that are ambiguity-averse in the sense of Ghirardato and Marinacci (2002), but not in the sense of Schemidler (1989), can accommodate Machina's now-famous example.
Bayesian Updating for General Maxmin-Expected Utility Preferences, September 2001. The main result of this paper has been incorporated in Section 4 of ``Dynamic Choice under Ambiguity'', available above. So this paper is basically obsolete...
