In this paper, we develop an analytically tractable dynamic model of optimal consumption and savings decisions with disastrous income risk. We first empirically explore the relations among consumption changes, aggregate income, disaster shock severity, and fiscal measures in 55 countries during...

To effectively cope with an unexpected, large, and negative income shock, I propose a life-cycle model for income risk management. I analyze the intertemporal consumption-investment problem in an incomplete market. I suggest a hybrid of the martingale approach and the dynamic programming...

In the aftermath of the financial crisis of 2008, there is increased concern about the potentially catastrophic pension default risk, which results in significant decreases in pension benefits. In order to address the challenge of annuity income uncertainty, I propose a dynamic annuitization...

We study the impact of income disaster-which can be triggered by various reasons such as pandemics and technological disruption-on Friedman's permanent income hypothesis. Although the hypothesis is still retained, our general equilibrium model offers two insights. First, with income disaster the...
