The well-documented nonparticipation in the stock market by many households and the highly negative correlation between stock and housing investment are puzzling. We show that stock and housing markets are cointegrated, and thus households significantly increase housing expenditure, reduce stock...

There exists one potential source which has not obtained full treatment in the recent consumption literature: a negative wealth constraint (NWC). An economic agent who faces the NWC can borrow up to a certain proportion of the present value of labor income. We present an analytically tractable...

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...

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...
