Abstract
. This article investigates the optimal investment, consumption, and life insurance strategies for households under the impact of health shock risk. Considering the uncertainty of the future health status of family members, a non homogeneous Markov process is used to model the health status of the wage earner. Drawing upon the theory of habit formation, we investigate the influence of different consumption habits on households’ investment, consumption, and life insurance strategies. Based on whether the wage earner is alive or not, we formulate and solve the corresponding Hamilton-Jacobi-Bellman (HJB) equations for the two scenarios of wage earner survival and wage earner’s demise, respectively, and obtain explicit expressions for the optimal investment, consumption, and life insurance strategies of households. Through sensitivity analysis of important parameters, it has been shown that the presence of health shocks within households has a negative impact on investment and consumption decisions, while the formation of consumption habits increases household propensity for precautionary savings.
