Micro data over the life cycle show different patterns for consumption for housing and non-housing goods: The consumption profile of non-housing goods is hump-shaped, while the consumption profile for housing first increases monotonically and then flattens out. These patterns hold true at each...

A major threat to Hawaii's ecosystem is the spread of invasive plant species. One such species is Miconia calvescens. Given that this plant was originally introduced to Hawaii by the horticulture industry and has negative effects on agricultural productivity, it is logical to find the farm...

We estimate a structural model of optimal life-cycle housing and nonhousing con- sumption in the presence of labor income and house price uncertainties. The model postulates constant elasticity of substitution between housing service and nonhousing consumption, and explicitly incorporates a...

We reexamine the empirical relevance of habit formation preferences with micro-data on households' portfolio choices. We first derive the analytical solution to the risky asset share in a theoretical model with both habits and time-varying labor income. Our analytical results indicate that (1)...

In this article, we explore whether relative risk aversion varies with wealth. First, we derive theoretical predictions on how risky shares respond to wealth uctuations in a portfolio choice model with both external habits and time-varying labor income. Our analytical results indicate that: (1)...

We document trends in higher education costs and tuition over the past 50 years. To explain these trends, we develop and simulate a general equilibrium model with unbalanced technical change. We assume that higher education suffers from Baumol's (1967) service sector disease, in that the...

This paper incorporates home production into a dynamic general equilibrium model of overlapping generations with endogenous retirement to study Social Security reforms. As such, the model differentiates both consumption goods and labor effort according to their respective roles in home...

We incorporate home production in a dynamic stochastic general equilibrium model of household consumption and saving with illiquid housing and endogenous collateralized borrowing constraint. We show that such a model is capable of explaining life-cycle patterns of households' time use and their...

In this paper, we document households' time use and consumption over the life cycle. Specifically, households spend a roughly constant amount of hours doing market work and home production early in the life cycle. At age 50, they begin to reduce their market hours sharply and increase home...

We incorporate home production in a dynamic general equilibrium model of consumption and savings with illiquid housing and a collateralized borrowing constraint. The calibrated model explains life‐cycle patterns of households' time use and consumption of different categories documented from...
