How do inheritances affect social structure, wealth formation, and provision for old age? Who benefits the most from inheritances? We analyse these questions based on the 2001 wave of the Socio-Economic Panel, which gives information on the deceased, and on the type, time, chance, and amount of the inheritance. Our findings confirm the theoretical hypotheses in general. Inheritance research is intergenerational research: most inheritances come from parents and benefit the recipients in the second half of their lives. However, the chances of receiving an inheritance and amounts inherited are distributed very unevenly. West Germans inherit significantly more frequently and larger amounts than East Germans due to the continuing effects of conditions in the former GDR. Foreigners have particularly low chances of receiving an inheritance. Thus, provision for old age through inheritance is limited mainly to specific groups of people. The most advantaged groups are the highly educated classes, which already receive higher (retirement) income. 相似文献

The number of households in the United States increased by over fifty percent in the 1960s and 1970s, nearly double the rate of population growth. Part of the increase is explained by the movement of large cohort groups of the population into prime household-forming age categories, but higher headship rates also contribute. Age-specific headship rate increases result from non-demographic factors, and this paper focuses on the role of government transfer payment programs. Specifically considered are Social Security, Aid to Families with Dependent Children, and Food Stamps. These programs are found to have accounted for as many as 4 million net household formations between 1961 and 1984. The findings have implications for expected households formations in the 1990s. 相似文献

The increase in the thyroid cancer incidence in France observed over the last 20 years has raised public concern about its association with the 1986 nuclear power plant accident at Chernobyl. At the request of French authorities, a first study sought to quantify the possible risk of thyroid cancer associated with the Chernobyl fallout in France. This study suffered from two limitations. The first involved the lack of knowledge of spontaneous thyroid cancer incidence rates (in the absence of exposure), which was especially necessary to take their trends into account for projections over time; the second was the failure to consider the uncertainties. The aim of this article is to enhance the initial thyroid cancer risk assessment for the period 1991-2007 in the area of France most exposed to the fallout (i.e., eastern France) and thereby mitigate these limitations. We consider the changes over time in the incidence of spontaneous thyroid cancer and conduct both uncertainty and sensitivity analyses. The number of spontaneous thyroid cancers was estimated from French cancer registries on the basis of two scenarios: one with a constant incidence, the other using the trend observed. Thyroid doses were estimated from all available data about contamination in France from Chernobyl fallout. Results from a 1995 pooled analysis published by Ron et al. were used to determine the dose-response relation. Depending on the scenario, the number of spontaneous thyroid cancer cases ranges from 894 (90% CI: 869-920) to 1,716 (90% CI: 1,691-1,741). The number of excess thyroid cancer cases predicted ranges from 5 (90% UI: 1-15) to 63 (90% UI: 12-180). All of the assumptions underlying the thyroid cancer risk assessment are discussed. 相似文献

We propose to use multilevel discrete-time hazard models to assess the impact of societal and individual level covariates on the timing and occurrence of third births. We focus mainly on the impact of educational attainment on third births across 15 European countries. From the analysis in this paper, the effect of education on the propensity to have a third child is found to be negative. This education effect is not significantly weakened by the Nordic countries, but living in Scandinavia does increase the hazard for a third birth. 相似文献

Scoring rules on dichotomous preferences 总被引:1,自引:0,他引:1

In this paper, we study individual incentives to report preferences truthfully for the special case when individuals have
dichotomous preferences on the set of alternatives and preferences are aggregated in form of scoring rules. In particular,
we show that (a) the Borda Count coincides with Approval Voting, (b) the Borda Count is the only strategy-proof scoring rule,
and (c) if the size of the electorate is greater than three, then the dichotomous preference domain is the unique maximal
rich domain under which the Borda Count is strategy-proof.
I thank Jordi Massó for his supervision and his never-ending encouragement. Miguel-ángel Ballester showed me how to improve
on earlier drafts of the paper. Salvador Barberà, Carmen Bevía, Bhaskar Dutta, Lars Ehlers, Alejandro Neme, Shmuel Nitzan
and Yves Sprumont helped me a lot with their comments. All remaining errors are mine. This research was undertaken with support
from the fellowship 2001FI 00451 of the Generalitat de Catalunya and from the research grant BEC2002-02130 of the Ministerio
de Ciencia y Tecnología of Spain while I have been a graduate student at Universitat Autònoma de Barcelona. 相似文献

This paper studies a deviant social position within a small group of Italian Fishermen. The role of “court-jester” emerges and, as the title suggests, the relation between this role and the inherent properties of the deviant are explored. It is argued that the emergence of roles among deviant social positions is dependent upon the personal attributes of the deviant and the characteristics of his relations to other members of the group. 相似文献

The study of statistical inference for stochastic processes has evolved along two paths. Some problems related to particular processes have been studied, and also some trials to extend general results obtained for independent identically distributed random variables have been made. We retrace the first main contributions, evaluate their influence, and give an idea of the evolution of the research in the field of statistical inference made with observations coming from a stochastic process. 相似文献
