    • Consumption-Portfolio Choice with Preferences for Cash 

      Kraft, Holger; Weiss, Farina (2018-07-12)
      This paper studies a consumption-portfolio problem where money enters the agent's utility function. We solve the corresponding Hamilton-Jacobi-Bellman equation and provide closed-form solutions for the optimal consumption ...
    • Optimal Consumption and Investment with Epstein-Zin Recursive Utility 

      Kraft, Holger; Seiferling, Thomas; Seifried, Frank Thomas (2016-07-04)
      We study continuous-time optimal consumption and investment with Epstein-Zin recursive preferences in incomplete markets. We develop a novel approach that rigorously constructs the solution of the associated Hamilton-Jac ...
    • Systemic Risk and Sovereign Debt in the Euro Area 

      Radev, Deyan (2013-12-13)
      We introduce a new measure of systemic risk, the change in the conditional joint probability of default, which assesses the effects of the interdependence in the financial system on the general default risk of sovereign ...
