We build a market equilibrium theory of asset prices under Knightian uncertainty. Adopting the mean-variance decisionmaking model of Maccheroni, Marinacci, and Ruffino (2013a), we derive explicit demands for assets and formulate a robust version of the two-fund separation theorem. Upon market...

This paper investigates the effect of inflation uncertainty on the portfolio behavior of households and the equilibrium structure of capitol market rates. The principal findings regarding portfolio behavior are: (1.) In the presence of inflation uncertainty, households will have an...
