The Dynamics of Crises and the Equity Premium
(2015-05-18)
It is a major challenge for asset pricing models to generate a high equity premium and a low risk-free rate while imposing realistic consumption dynamics. To address this issue, our paper proposes a novel pricing channel: ...
Consumption Habits and Humps
(2015-07-10)
We show that the optimal consumption of an individual over the life cycle can have the hump shape (inverted U-shape) observed empirically if the preferences of the individual exhibit internal habit formation. In the absence ...
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 ...
Stochastic Differential Utility as the Continuous-Time Limit of Recursive Utility
(2013-05-10)
We establish a convergence theorem that shows that discrete-time recursive utility, as developed by Kreps and Porteus (1978), converges to stochastic differential utility, as introduced by Duffie and Epstein (1992), in the ...
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 ...
Asset Pricing Under Uncertainty About Shock Propagation
(2014-03-25)
We analyze the equilibrium in a two-tree (sector) economy with two regimes. The output of each tree is driven by a jump-diffusion process, and a downward jump in one sector of the economy can (but need not) trigger a shift ...
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 ...
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 ...
Consumption and Wage Humps in a Life-Cycle Model with Education
(2015-02-24)
The observed hump-shaped life-cycle pattern in individuals’ consumption cannot be explained by the classical consumption-savings model. The consensus explanation is that the hump is caused by constraints and unspanned ...
Housing Habits and Their Implications for Life-Cycle Consumption and Investment
(2017-01-26)
We solve a rich life-cycle model of household decisions involving consumption of perishable goods and housing services, habit formation for housing consumption, stochastic labor income, stochastic house prices, home renting ...
