In the framework of the intertemporal asset allocation problem, this dissertation focuses on the modelling of inflation risk and its impact on intertemporal asset allocation strategies. The contributions of this dissertation to the current literature are as follows.First, in considering...

The paper studies a credit market model with endogenous credit cost and debt constraints in which multiple candidates for steady state equilibria arise.
