We study the sensitivity of optimal consumption streams with respect to perturbations of the random endowment. At the leading order, the consumption adjustment does not matter: any choice that matches the budget constraint simply shifts the original utility by the marginal value of the...

This paper investigates the impact of the inclusion of housing in a household portfolio on household's intertemporal decision making. Residential housing is one of the principal assets households hold, and thus changes in housing return can affect household consumption over time. We assess...

This paper characterizes optimal consumption and investment policies for investors with asset return predictability, stochastic labor income and endogenously-determined retirement. We find that the ratio of total wealth-to-labor income (normalized wealth) is the primary determinant of the...

We show individuals investments chase stock index returns and are financed by foregoing consumption, even after controlling for individual-account level portfolio income effects and other high dimensional fixed effects. This effect only exists for positive stock index returns with no effects for...

We investigate the dynamic consumption and portfolio selection problem of an agent who has an intertemporal preference with loss and risk aversion, as proposed by Choi et al. (2019a). We disentangle the effects of loss aversion from those of risk aversion on risk taking. We show by simulation...

The instability of wealth effect on consumption over the business cycles is widely recognized in recent empirical studies. We develop a consumption and investment problem for an investor with direct preference for wealth where the drift and volatility of asset return switches between two...

The well-documented nonparticipation in the stock market by many households and the highly negative correlation between stock and housing investment are puzzling. We show that stock and housing markets are cointegrated, and thus households significantly increase housing expenditure, reduce stock...

We develop a new dynamic continuous-time model of optimal consumption and investment to include independent stochastic labor income. We reduce the problem of solving the Bellman equation to a problem of solving an integral equation. We then explicitly characterize the optimal consumption and...

We propose a tractable dynamic framework for the joint determination of optimal consumption, portfolio choice, and healthcare irreversible investment. Our model is based on a Merton's portfolio and consumption problem, where, in addition, the agent can choose the time at which undertaking a...
