Sophisticated agents with self-control problems value commitment devices that constrain future choices. Using Australian household data, I test whether these households value commitment devices in the form of illiquid pension contributions. Applying various probabilistic choice models, the...

This paper investigates the quantitative importance of different savings motives on the distributions of wealth and consumption and aggregate capital accumulation by solving an overlapping generations model with intragenerational heterogeneity. Agents differ in age, ability, earnings shocks, and...

This paper studies competitive equilibria of a production economy with aggregate productivity shocks and with a continuum of consumers subject to borrowing constraints and individual labor endowment shocks. The dynamic economy is described in terms of sequences of aggregate distributions. The...

Recent models of procrastination due to self-control problems assume that a procrastinator considers just one option and is unaware of her self-control problems. We develop a model where a person chooses from a menu of options and is partially aware of her self-control problems. This menu model...

We use CEX repeated cross-section data on consumption and income, to evaluate the nature of increased income inequality in the 1980s and 90s. We decompose unexpected changes in family income into transitory and permanent, and idiosyncratic and aggregate components, and estimate the contribution...

This paper investigates whether the inclusion of housing in a household portfolio is important to the household’s intertemporal decision making. Households hold portfolios of assets rather than a Treasury bill and/or a stock index and make their spending decisions based on expected total...

This paper investigates whether the rate of interest such as the Treasury bill rate or the rate of return such as the return on a household portfolio is more relevant to the household’s intertemporal decision making. In a current era, households are diversifiers (to use Tobin’s 1958 term)...

This paper explores the consequences of skill biased technological progress on the savings rates. The literature, both theoretical and empirical, on the causes and consequences of skill biased technological progress in the past few years has burgeoned considerably. So has the literature on...

In this paper we show that the solution to the standard consumer maximisation problem which is augmented by habit-persistence can imply a positive and linear relationship between changes in the level of savings and changes in present income. We show that these savings-income dynamics contrast...

The current literature offers two views on the nature of the income process. According to the first view, which we call the “restricted income profiles” (RIP) model (MaCurdy, 1982), individuals are subject to large and very persistent shocks, while facing similar life-cycle income profiles...
