In this study, we investigate an optimal consumption and investment problem of an economic agent who faces a welfare constraint; the agent does not accept her expected utility (continuation value) falls below a certain fixed level regardless of the time and state. This optimization problem...

This paper studies a continuous-time optimal consumption and portfolio selection problem when an economic agent with recursive utility has stochastic income and liquidity constraints. To tackle this problem, we introduce a transform of the Hamilton-Jacobi-Bellman equation into a free boundary...

We examine the consumption and portfolio decisions of an agent with Friedman-Savage type period utility in continuous time. We find the Friedman-Savage consumer does not gamble, but will aggressively invest in risky activities for wealth levels that support a minimum subsistence level of...
