This is a short survey on consumption theory. Consumption is important to both fluctuation and growth. In addition, consumption introduces some important issues involving financial markets and portfolio decisions. We will describe consumption decisions in a dynamic context. Uncertainty about...

This paper proposes a new approach for modeling investor fear after rare disasters. The key element is to take into account that investors' information about fundamentals driving rare downward jumps in the dividend process is not perfect. Bayesian learning implies that beliefs about the...

This paper employs cohort technique and Consumer Expenditure Survey data to construct average age-profiles of consumption and income over the working lives of typical households across different education and occupation groups. Using these profiles, we estimate a structural model of optimal...

This paper decomposes the sources of risk to income that individuals face over their lifetimes. We distinguish productivity risk from employment risk and identify the components of each using the Survey of Income and Program Participation and the Panel Study of Income Dynamics. Estimates of...

In this paper, a stochastic endogenous aggregative growth model is constructed and two main results are established, based on endogenous horizon of the economy and endogenous terminal capital stock, which is also efficient capital accumulation in some sense. First, strong turnpike theorems under...

Households who wish to extract home equity through refinancing their mortgage face a hidden transaction cost. The real value of the fixed nominal mortgage payment declines over time with inflation. The change in the real value of the mortgage payments from taking on a new mortgage is positive...

This paper uses a dynamic optimization model to estimate the welfare gains of hedging against commodity price risk for commodity-exporting countries. We show that the introduction of hedging instruments such as futures and options enhances domestic welfare through two channels. First, by...

This paper derives the general equilibrium effects of rational inattention (or RI; Sims 2003, 2010) in a model of incomplete income insurance (Huggett 1993, Wang 2003). We show that, under the assumption of CARA utility with Gaussian shocks, the Permanent Income Hypothesis (PIH) arises in...

In this paper, we examine the joint consumption-portfolio decision of an agent with limited information-processing capacity (rational inattention or RI) in the sense of Sims (2003) within a non-linear-quadratic (non-LQ) setting. Our model predicts that, as processing capacity falls, agents...

We examine the optimal consumption decisions of households in a micro-founded framework that assumes two financial frictions: heterogeneity between borrowing and saving households, and endogenous default. We study default in the context of two-period overlapping processes of consumer behavior,...
