The paper provides an empirical analysis of saving and consumption choices of the elderly in Germany, based on the German income and expenditure surveys 1978 and 1983. Main feature of these data is the large sample size making it possible to analyze saving and consumption patterns of the very old (aged 75 and above).The observed age-consumption profiles are very different from those predicted by the pure life-cycle theory. Although wealth is declining between age 60 and 70, it increases again after 70, such that the very old have the highest savings rates among all age groups and accumulate wealth rather than decumulate it. These profiles are not confounded by cohort effects and mortality differences. The corresponding expenditure data suggest the following explanation: due to the generous German pension system and the almost complete coverage of health expenses by the mandatory health insurance in Germany, the declining consumption n very old age cannot exhaust the annuity income of the elderly such that wealth is being accumulated in old age.Research in this paper was supported by the National Institute on Aging, grant no. 3 PO1 AG05842-01. I appreciate the helpful comments by Doug Bernheim, Angus Deaton, Daniel McFadden, Jonathan Skinner, Konrad 'Stahl and David Wise, and two anonymous referees. I am indebted to Hermann Buslei and Johannes Velling who provided most valuable and able assistance.  相似文献

Adolescents' social behaviors remain a mystery to parks and recreation providers. Adolescence is a "high-risk" time for all youth in terms of experimenting with potentially health-compromising behavior, whether alcohol, drugs, or sex. Most of these antisocial behaviors occur during adolescents' leisure time. These inferences gave impetus to this research effort. The study was designed to ascertain information on adolescents' preferences for pleasure: drugs or recreation. Data were collected from a sample of 100 high school students from a medium-sized college town, and 100 students from a rural town in Florida. Findings revealed four statistically significant associations in the motives or pleasures sought in recreation and in drug behaviors: "enhancement of popularity," "provision of a means for self-discovery," "achievement of personal goal," and means to rebel against parents. In reference to the latter motive, findings revealed that neither drugs nor recreation were used to rebel against parents. Findings also provide documentation of the value of recreation in insulating adolescents against many of the stressors of contemporary life.  相似文献

This research note briefly outlines International Labour Organization concerns about return migration in developing countries, research being done in the field, and activities in related fields. Attention is being focused on the following topics and areas of study: 1) recommendations and conventions which cover workers generally and migrant workers particularly; 2) measures to avoid the departure of skilled workers from developing countries; 3) special problems encountered in improving migrant professionals' working conditions; 4) developing a central pool of information on labor markets and employment at the international level; 5) bilateral or multilateral migration agreements to optimize the flows of health personnel, scientific workers, engineers, and high level technicians, protecting their rights, and facilitating their reintegration into the country of origin; 6) creating a compensation scheme for skill outflows and training substitutes to fill the gaps left behind by migration; 7) classifying migratory policies adopted by developing countries; 8) reattraction of needed skills to developing countries of origin; 9) transfer of know-how through expatriate nationals; 10) labor reinsertion patterns of migrants returning to Greece, Italy, Portugal, and Spain; 11) Socioeconomic reintegration of migrants returning to Pakistan and Uruguay; and 12) Sri Lanka's experience with self-employment schemes for returned migrants.  相似文献

The author focuses on characteristics of Polish immigrants in Minnesota in the years since World War II. Particular attention is given to the immigrants' adaptation to the American way of life and to democratic institutions after being accustomed to centralized power in a socialist system. "This article is based on participant observation, publications concerning immigration to the United States, and unstructured interviews with newcomers from Poland and other Eastern European countries." Distinctions are made among the characteristics of Polish-Americans, pre-World War II immigrants, war immigrants, and those who have come during the last 20 years, including groups that the author identifies as the "calculated-decision" immigrants, the post-Solidarity immigrants, and the "adjusted visitor" immigrants. Consideration is given to the demographic characteristics, legal status, education and employment, and territorial mobility of 35 Poles living in Minnesota who were interviewed by the author.

Contributors to disruption and dissolution of older-child adoptions   总被引:1,自引:0,他引:1  
According to recent evidence, adoptive placements that do not work out are increasingly common. This article reviews research on rates of, and contributors to, adoption and "foster-adoption" disruptions and dissolutions. Implications for practice are included.  相似文献

Abstract Both politicians and voters were asked to predict outcomesof two Oregon ballot measures in 1982. As expected, politicians'predictions always were closer to the mark than voters' were.Further, voters showed stronger signs of wishful thinking (the"Looking-Glass effect") in their predictions than did politicians.Using published preelection polls apparently improved politicians'accuracy in 1982, as well as voters' accuracy in a separate1984 survey. No other sources of data improved predictive accuracy.Findings have implications for theories of representative governmentand are consistent with a new theory of public opinion.  相似文献

The economic adaptation of immigrants to Canada is analyzed using government data on the labor force and landed immigrants. In particular, the labor force experience of a sample of immigrants in Canada is examined and compared with that of a Canadian cohort with regard to length of unemployment and income. "Differences in unemployment and insurable earnings are examined by age, sex, immigrant category..., world area of last permanent residence, official language abilities, education, and region of residence."

The author reviews migration data sources and government collection agencies in the Philippines. He finds that "despite the importance of international migration for national policy, efforts to correct the serious data limitations in the area of migration statistics have been limited and uncoordinated. In fact, most estimates of emigration levels from the Philippines still rely heavily on the data gathered by receiving countries."  相似文献

An experiment was designed to examine the role of a person's predispositions toward communication in reactions to violations of proxemic expectations. Working with Burgoon's (1983) violations of nonverbal expectations model, Buller and Burgoon (1986) predicted that predispositions may bias evaluations of initiator reward and violation valence. Apprehensive individuals should unfavorably evaluate the initiator, negatively valence a violation and comply less, while nonapprehensive individuals should favorably evaluate the initiator, positively valence a violation, and comply more. Alternately, this paper proposes that predispositions may affect arousal-induction rather than initiator evaluation and violation valencing. Following Patterson (1983), apprehensives should experience more arousal and comply more to reduce the arousal, whereas nonapprehensives should experience less arousal and comply less. Four initiators engaged 90 subjects in experimental conversations which ended with a request for the subjects' signature on a petition. Initiators either remained at the normative distance, moved one seat closer, or moved one seat farther from the subject. Results showed that apprehensives and subjects experiencing close violations complied more, suggesting that communication apprehension influences arousal-induction. Communication apprehension had no main effect on perceptions of initiator attractiveness and similarity, implying that arousal not perceptions of the initiator is affected by predispositions toward communication. Initiator gender again emerged as an important characteristic which influences a subject's perceptions of initiator reward.  相似文献
