Abstract

In this work, we address the optimal retirement problem in the presence of a stochastic wage, formulated as a free boundary problem. Specifically, we explore an incomplete market setting where the wage cannot be perfectly hedged through investments in the risk-free and risky assets that characterize the financial market.

Complexity vs Empirical Score

• Math Complexity: 9.5/10
• Empirical Rigor: 1.0/10
• Quadrant: Lab Rats
• Why: The paper employs advanced mathematical techniques including stochastic control, free boundary problems, and duality transformations with extensive formal derivations and PDE analysis, but focuses entirely on theoretical modeling with no empirical data, backtests, or implementation details.
