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...

In this paper, we analyze the financial asset selection behavior of Japanese households. Especially, we focus on whether or not liquidity constraint decreases the amount of a householdfs risky assets. To investigate this, we first empirically examine which types of household suffer from...

This paper explores the consequences of rising returns to human capital investment on the personal savings rate. Over the past two decades, the return to college education has increased relative to high school education leading economists to argue the presence of 'skill biased technological...

Suppose an altruistic person, A, is willing to transfer resources to a second person, B, if B comes upon hard times. If B anticipates that A will act in this manner, B will save too little from both agents' point of view. This is the Samaritan's dilemma. The logic of the dilemma has been...

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)...

We investigate the role that self-control problems modeled as time-inconsistent, present-biased preferences and a person's awareness of those problems might play in leading people to develop and maintain harmful addictions. Present-biased preferences create a tendency to over-consume addictive...

People underappreciate how their own behavior and exogenous factors affect their future utility, and thus exaggerate the degree to which their future preferences resemble their current preferences. We present evidence which demonstrates the prevalence of such projection bias, and develop a...

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...
