Working Papers

• "Uncertainty averse preferences," with Simone Cerreia, Fabio Maccheroni, and Luigi Montrucchio, September 2008.

We study uncertainty averse preferences, that is, complete and transitive preferences that are convex and monotone. We establish a representation result, which is at the same time general and rich in structure. Many objective functions commonly used in applications are special cases of this representation.

• "Objective and subjective rationality in a multiple prior model," with Itzhak Gilboa, Fabio Maccheroni, and David Schmeidler, March 2008.

• "Social decision theory: choosing within and between groups," with Fabio Maccheroni and Aldo Rustichini, March 2008.

• "Unique solutions of some recursive equations in economic dynamics," with Luigi Montrucchio, June 2007.

We study unique and globally attracting solutions of a general nonlinear equation that has, as special cases, some recursive equations widely used in Economics.

• "Recursive smooth ambiguity preferences," with Peter Klibanoff and Sujoy Mukerji, May 2006.
  
  We provide a recursive dynamic versione of the model proposed in our earlier static paper.

• "Cores and stable sets of finite dimensional games," with Luigi Montrucchio. February 2003.
  
  In this paper we study exact TU games having finite dimensional non-atomic cores, a class of games that includes relevant economic games. We first characterize them by showing that they are a particular type of market games. Using this characterization, we then show that in such a class the cores are their unique von Neumann-Morgenstern stable sets.
