Dynamic asset allocation with default and systemic risks

Abstract

Systemic risk breeds default risk. I investigate the optimal portfolio implications of their joint presence for non-myopic investors in arbitrage-free markets when such risks take the form of asset value discontinuities. I contribute to the multiple-asset jump-diffusion portfolio analysis of Das and Uppal (J Financ 59:2809–2834, 2004) by introducing default risk and its investment-horizon effects on optimal portfolios (the optimal investment rules in Das and Uppal (J Financ 59:2809–2834, 2004) are time-invariant) and by linking excess expected returns to risk exposures.
