In this paper, I survey the previous literature on the saving behavior of the aged in Japan and then present some survey data on the saving behavior of the aged in Japan that became available recently. To summarize the main findings of this paper, all previous studies as well as the newly...

This paper finds that individuals in Japan do not leave very significant bequests, that parents often require a quid pro quo for bequests to their children, and that wealthier individuals leave less bequests, meaning that bequests ameliorate wealth inequalities. -- Bequests ; Inheritances ;...

We provide a model with endogenous portfolios of secured and unsecured household debt. Secured debt is collateralized by durables whereas unsecured debt can be discharged in bankruptcy procedures. We show that the model matches the main quantitative characteristics of observed wealth and debt...

This paper examines the structure and evolution of consumption and consumption growth inequality. Once heterogeneous agents relate their neighbors' consumption to their own, consumption volatility and inequality are affected. The relationship predicted between the group average consumption...

It has been argued that increased life expectancy raises the rate of return on education, causing a rise in the investment in education followed by an increase in lifetime labor supply. Empirical evidence of these relations is rather weak. Building on a lifecycle model with uncertain longevity,...

The budget constraint requires that, eventually, consumption must adjust fully to any permanent shock to income. Intuition suggests that, knowing this, optimizing agents will fully adjust their spending immediately upon experiencing a permanent shock. However, this paper shows that if consumers...

This paper considers the quantitative role of growth in the size of the social security program in contributing to the collapse of personal saving in the U.S. over the last few decades. Using a calibrated, general equilibrium life-cycle model this paper shows that social security may not be to...

This paper presents data on Japan’s household saving rate, considers the reasons for Japan’s high household saving rate in the past and the reasons for the recent decline therein, projects future trends in Japan’s household saving rate, and consider the implications of my findings. It...

We analyze the impact of population aging on Japan’s household saving rate and on its public pension system and the impact of that system on Japan’s household saving rate and obtain the following results: first, the age structure of Japan’s population can explain the level of, and past and...

In this paper, we demonstrate how age-adjusted inequality measures can be used to evaluate whether changes in inequality over time are due to changes in the age structure. To this end, we use administrative data on earnings for every male Norwegian during 1967-2000. We find that the substantial...
