We analyze dynamic interactions between market insurance, the stock of insurable assets and liquid wealth accumulation in a model with non-durable and durable consumption. The stock of the durable is exposed to risk against which households can insure. Since the model does not have a closed form...

Empirical evidence suggests that it may cost time, effort, and resources to implement an optimal consumption-saving plan, although the cost may differ across individuals. This paper explores the implications of such friction. We begin by documenting a series of facts on consumption and savings...

Contrary to the usual presumption that welfare is maximized if consumers behave rationally, we show in a two-period overlapping generations model that there always exists a rule of thumb that can weakly improve upon the lifecycle/permanent-income rule in general equilibrium with irrational...

This paper analyzes how information-processing limitations affect consumption in a dynamic full-fledged non-linnear quadratic Gaussian (LQG) setting. In the model, risk-averse consumers rationally choose the quantity and quality of information to process about their wealth, while constrained by...

We use a new panel dataset of credit card accounts to analyze how consumers responded to the 2001 federal income tax rebates. We estimate the monthly response of credit card payments, spending, and debt, exploiting the unique, randomized timing of the rebate disbursement. We find that on average...

We collect 2,735 estimates of the elasticity of intertemporal substitution in consumption from 169 published studies that cover 104 countries during different time periods. The estimates vary substantially from country to country, even after controlling for 30 aspects of study design. Our...

This paper integrates imperfect self-control into the standard model of endogenous growth. Individuals are conceptualized as dual-selves consisting of a long-run planner and a short-run doer. The long-run self can partly control the short-run self´s strife for immediate gratification. It is...
