The Statistical Policy Division of the Office of Management and Budget has the overall responsibility for the planning and coordination of U.S. government statistics. The present staff of the Statistical Policy Division is attempting, through an integrated publication entitled “A Framework for Planning U.S. Federal Statistics, 1978–1989,” to state its perspective on necessary developments in the coming years. This article illustrates the character of the Framework materials and outlines the process for public review and comment on this undertaking. 相似文献

We show that the existing tests for asymptotic independence are sensitive to outliers. A robust test is proposed. The new test is made stable under contamination through a shrinkage scheme. Simulations show that the new test performs well in the presence of contaminated data while maintaining good properties when there is no contamination. An application to real data shows the added value of our new robust approach. 相似文献

This paper estimates the impact of cohort size on wages using data on young males in European regions covering 2004–10. The effect of cohort size on wages is identified through an instrumental variables strategy which, in contrast to previous analyses of European data, addresses self‐selection into geographical areas as well as into educational groups. The results suggest that cohort size has a significant negative effect on male wages for individuals with secondary education — the largest group — but not for individuals with less than secondary education or tertiary education. This effect is underestimated if self‐selection into geographical areas is not addressed. 相似文献

This paper simulates the distributional impact of the Russian personal income tax (PIT) following the flat tax reform of 2001 using data from the Russian Longitudinal Monitoring Survey. I decompose the change in the distribution of net income into a direct (tax) effect and an indirect effect. The indirect effect is further decomposed into evasion and productivity effects using existing estimates of these respective elasticities. As expected, the direct tax effect increased net income inequality. Changes in the pre-tax distribution (indirect effect), on the other hand, had a large negative impact on inequality thus leading to an overall decline in net income inequality. I also find that the tax-induced evasion response increased reported net income inequality while reducing consumption inequality. To the extent that consumption approximates actual income, these results demonstrate that the flat tax reform had a much smaller effect on actual income inequality than on reported income inequality. More importantly, relative to non-tax factor, the reform had little overall effect on income inequality. This suggests that objection to flatter tax schedules on the grounds of income inequality is mostly misguided, especially in transitional countries with high levels of evasion. 相似文献

This article argues that there is a natural solution to carry out interpersonal comparisons of utility when the theory of gambles is supplemented with a group operation of joint receipts. If so, three types of people can exist, and the two types having multiplicative representations of joint receipt have, in contrast to most utility theories, absolute scales of utility. This makes possible, at least in principle, meaningful interpersonal comparisons of utility with desirable properties, thus resolving a long standing philosophical problem and having potentially important implications in economics. Two behavioral criteria are given for the three classes of people. At this point the relative class sizes are unknown. 相似文献

Abstract Objective: Determine the effects of a short-term, multi-faceted, point-of-selection intervention on college students’ perceptions and selection of 10 targeted healthful foods in a university dining hall and changes in their self-reported overall eating behaviors. Participants: 104 college students, (age 18–23) completed pre-I and post-I surveys. Methods: Pre-survey collected at dining hall in April 2007, followed by 3-week intervention then post-survey collected via email. Healthy choice indicators, large signs, table tents, flyers and colorful photographs with “benefit-based messages” promoted targeted foods. Response rate to both surveys was 38%. Results: Significantly more participants reported that healthful choices were clearly identified in the dining hall after the intervention. Over 20% of participants reported becoming more aware of healthful food choices in the dining hall after the intervention. Significant increases in self-reported intake were reported for cottage cheese and low-fat salad dressing, with a trend toward increased consumption of fresh fruit. Seven of the 14 assessed eating behaviors had significant changes in the desired direction. Increased awareness of healthful foods was the top reason for self-reported changes in overall eating behaviors. Conclusion: Short-term, multi-faceted, point-of-selection marketing of healthful foods in university dining halls may be beneficial for improving college students’ perceptions and selections of targeted healthful foods in the dining hall and may improve overall eating behaviors of college students. 相似文献

In this study we examine reasons that professionals become and remain members of professional associations. We looked at tangible and symbolic benefits that an association can provide to attract members. Satisfaction with these benefits was linked to overall membership satisfaction and intent to renew the membership. We also considered the role of customer service in shaping members' attitudes. Based on the responses of 1,980 members of a large international accounting association, we found that members who were satisfied with their benefits and with the quality of customer service reported higher membership satisfaction and intent to renew. We also found that professionals who were more involved in the association were more satisfied with it. Contrary to predictions, younger professionals were less concerned with the value of the benefits of membership. As expected, longer‐tenured members were more likely to consider maintaining their memberships. We conclude with a discussion of practical and research implications for the management of professional associations. 相似文献

The use of assistive aids in sexual rehabilitation after prostate cancer (PCa) was examined in 124 gay, bisexual, and other men who have sex with men (GBM) and 225 heterosexual men. GBM were significantly more likely to use assistive aids (79% versus 56%), to try multiple assistive aids (M = 1.65 versus M = 0.83) including medication, penile injection, penile implant, vacuum pump, and nonmedical sex aids, and to seek information about sexual rehabilitation on the Internet, through counseling, or in a support group. There were no differences between the groups in satisfaction with the use of assistive aids. However, use of aids was a significant negative predictor of sexual functioning for GBM and a significant positive predictor for heterosexual men. Interview accounts described satisfaction with assistive aids in terms of maintaining erectile functioning and relationships. The majority of men in the study also described hindrances, both physical and social, resulting in discontinuation of assistive aids, including perceived artificiality, loss of sexual spontaneity, side effects, failure to achieve erectile response, cost, and lack of access to information and support. It is concluded that the specific needs and concerns of GBM and heterosexual men regarding sexual rehabilitation after PCa need to be addressed by clinicians. 相似文献
