In this paper we examine the link between wage inequality and consumption inequality using a life cycle model that incorporates household consumption and family labor supply decisions. We derive analytical expressions based on approximations for the dynamics of consumption, hours, and earnings...

Exponential-growth bias (EGB) is the tendency for individuals to partially neglect compounding of exponential growth. We develop a model wherein biased agents misperceive the intertemporal budget constraint, and derive conditions for overconsumption and dynamic inconsistency. We construct an...

How are substitution in the spatial and in the temporal sense connected? Can estimates based on data with spatial variation be transmitted into values appropriate for exploring temporal variation, and vice versa? This paper, building on, inter alia, Frisch (1959), attempts to give some...

In this paper, we examine the effect of observed and unobserved heterogeneity in the desire to die with positive net worth. Using a structural life-cycle model nested in a switching regression with unknown sample separation, we find that roughly 70 percent of the elderly single population has a...

Since the end of the eighties the Becker and Murphy model of rational addiction has been the dominant approach to estimate addiction effects. A rational addictive consumer, a smoker for instance, is supposed to maximize over the life cycle a stable utility function and to be fully aware of the...

In this paper it is shown that the intratemporal and intertemporal preferences of each decision maker in the household can be identified even if individual consumption is not observed. This identification result is used jointly with the Consumer Expenditure Survey (CEX) to estimate the...

The paper investigates the role of the Intertemporal Elasticity of Substitution (IES ) in determining the equity premium. This is done in an overlapping generations economy populated by agents that live for 2 periods and maximize a Kihlstrom-Mirman expected utility function. The equity premium...

We derive revealed preference tests for models where individuals use consideration sets to simplify their consumption problem. Our basic test provides necessary and sufficient conditions for consistency of observed choices with the existence of consideration set restrictions. The same conditions...

The observed hump-shaped life-cycle pattern in individuals' consumption cannot be explained by the classical consumption-savings model. We explicitly solve a model with utility of both consumption and leisure and with educational decisions affecting future wages. We show optimal consumption is...

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 risks. However, we explicitly show that the consumption hump naturally emerges...
