Option-Implied Information and Predictability of Extreme Returns
(2013-01-28)
We study whether prices of traded options contain information about future extreme market events. Our option-implied conditional expectation of market loss due to tail events, or tail loss measure, predicts future market ...
When Do Jumps Matter for Portfolio Optimization?
(2015-11-25)
We consider the continuous-time portfolio optimization problem of an investor with constant relative risk aversion who maximizes expected utility of terminal wealth. The risky asset follows a jump-diffusion model with a ...
Partial Information about Contagion Risk, Self-Exciting Processes and Portfolio Optimization
(2013-04-18)
This paper compares two classes of models that allow for additional channels of correlation between asset returns: regime switching models with jumps and models with contagious jumps. Both classes of models involve a hidden ...
Life Insurance Demand under Health Shock Risk
(2015-06-03)
This paper studies the life cycle consumption-investment-insurance problem of a family. The wage earner faces the risk of a health shock that significantly increases his probability of dying. The family can buy long-term ...
Asset Prices in General Equilibrium with Recursive Utility and Illiquidity Induced by Transactions Costs
(2015-02-01)
In this paper, we study the effect of proportional transaction costs on consumption-portfolio decisions and asset prices in a dynamic general equilibrium economy with a financial market that has a single-period bond and ...
Consumption-Investment Problems with Stochastic Mortality Risk
(2014-03-03)
I numerically solve realistically calibrated life cycle consumption-investment problems in continuous time featuring stochastic mortality risk driven by jumps, unspanned labor income as well as short-sale and liquidity ...
Critical Illness Insurance in Life Cycle Portfolio Problems
(2014-03-03)
I analyze a critical illness insurance in a consumption-investment model over the life cycle. I solve a model with stochastic mortality risk and health shock risk numerically. These shocks are interpreted as critical illness ...
Optimal Consumption and Investment with Epstein-Zin Recursive Utility
(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 ...
"Nobody is Perfect": Asset Pricing and Long-Run Survival When Heterogeneous Investors Exhibit Different Kinds of Filtering Errors
(2015-07-31)
In this paper we analyze an economy with two heterogeneous investors who both exhibit misspecified filtering models for the unobservable expected growth rate of the aggregated dividend. A key result of our analysis with ...
Optimal Consumption and Portfolio Choice with Loss Aversion
(2016-05-16)
This paper analyses the consumption-investment problem of a loss averse investor equipped with s-shaped utility over consumption relative to a time-varying reference level. Optimal consumption exceeds the reference level ...
