Portfolio Choices and Asset Prices: The Comparative Statics of Ambiguity Aversion

  • Christian Gollier

This paper investigates the comparative statics of "more ambiguity aversion" as defined by Klibanoff, Marinacci and Mukerji (2005 , "A Smooth Model of Decision Making under Ambiguity", Econometrica, 73 (6), 1849--1892). The analysis uses the static two-asset portfolio problem with one safe asset and one uncertain one. While it is intuitive that more ambiguity aversion would reduce demand for the uncertain asset, this is not necessarily the case. We derive sufficient conditions for a reduction in the demand for the uncertain asset and for an increase in the equity premium. An example that meets the sufficient conditions is when the set of plausible distributions for returns on the uncertain asset can be ranked according to their monotone likelihood ratio. It is also shown how ambiguity aversion distorts the price kernel in the alternative portfolio problem with complete markets for contingent claims. Copyright 2011, Oxford University Press.
