This study aims to generalize the following result of McDonald and Siegel (1986) on optimal investment: it is optimal for an investor to invest when project cash flows exceed a certain threshold. This study presents other results that refine or extend this one by integrating timing flexibility...

We develop a new dynamic continuous-time model of optimal consumption and investment to include independent stochastic labor income. We reduce the problem of solving the Bellman equation to a problem of solving an integral equation. We then explicitly characterize the optimal consumption and...

We develop an analytically tractable model of optimal financing policies for a risk averse decision maker who is exposed to climate risk causing a significant disruption to capital stock accumulation. We quantitatively identify certain thresholds of cash-capital ratio explicitly characterizing...

We develop a new dynamic model of annuitization in which a constant relative risk aversion utility maximizing individual receives non-traded labor income and has to decide on her allocation between a stock and a risk-free asset, as well as decide on the time when she starts her retirement...

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...

Models of optimal retirement should reflect market incompleteness in reality caused by disability risk. In this paper, we develop an analytic approach for optimal retirement models with disability risk. More precisely, we provide an analytically tractable characterization of total wealth that is...
