We give two procedures for determining whether efficient Pareto improving local changes are possible. When they are, the procedures compute for them. Any procedure generating efficient and Pareto improving changes can be replicated by these procedures. The two programs form a striking duality....

When asset markets are incomplete there are almost always many Pareto improving policy interventions. Remarkably, these interventions do not involve adding any new markets. Focusing on tax policy, I create a framework for proving the existence of Pareto improving taxes, for computing them, and...

To what extent do people avoid taxes on intra-family transfers (bequests and gifts), and how would integration (unification) of the different transfers taxes affect tax avoidance? These issues are important for families and their welfare, as well as for governments and their possibilities of...

The empirical evidence suggests that parents use inter vivos gifts (i.e., transfers of tangible and financial property) to compensate less well off children whereas post mortem bequests are divided equally among siblings. We study a theoretical model assuming, first, that the amounts given is...

This paper analyzes the determinants of the wealth decumulation behavior of the retired elderly in Japan using unique information from two household surveys, and by so doing, attempts to assess the relative importance of precautionary saving and bequest motives in explaining the lower than...

We quantify the size and tax-responsiveness of financial transfers made to heirs before death. The wealth of singles (including widows) with children declines substantially in anticipation of death. 92% of this decline is explained by transfers to children, while long-term care copayments can...

We study a growth model with two types of agents who are heterogeneous in their degree of family altruism. We prove that every equilibrium path converges to a unique steady state, and study the effect of altruism on the properties of steady-state equilibrium. We show that aggregate income is...

We conduct a theoretical and empirical analysis of why children live with (or near) their parents and provide care and assistance to them using microdata from a Japanese household survey, the Osaka University Preference Parameter Study. We find that the Japanese are more likely to live with (or...

Charitable bequests are a major source of income for charities but surprisingly little is known about them. The aim of this paper is to propose a multi-stage framework for analysing the bequest decision and to examine the evidence for Great Britain provided by new data on estates. The novelty of...

In this paper, we first provide a brief exposition of the simplest version of the selfish life cycle model or hypothesis, which is undoubtedly the most widely used theoretical model of household behavior in economics, and then survey the literature on household saving behavior in Japan (with...
