An Extension of a Measure of Polarization, with an application to the income distribution of five OECD countries 总被引:6,自引:0,他引:6
We introduce an extension of the Esteban and Ray [Econometrica, 62:819–851 1994] measure of polarization that can be applied to density functions. As a by-product we also derive the Wolfson [Am. Econ.
Rev., 84:353–358 1994] measure as a special case. This derivation has the virtue of casting both measures in the context of a (statistically) unified
framework. We study the polarization of the distribution of household income for five OECD countries (LIS database): US, UK,
Canada, Germany and Sweden.
The present paper is essentially based on Esteban, Gradín and Ray [9], published as #218 in the working papers series of the Luxembourg Income Study. Changes have been kept to a minimum. We
have provided a brief reference to the literature on polarization measurement that has appeared since then and have updated
the data of our application. 相似文献

The leptokurtosls of many security market return distributions can contaminate ordinary least squares estimates of the β coefficient of the market model. Partially adaptive estimation techniques accommodate the possibility of fat tailed distributions. this methodology limits the influence of extremely large residuals and yields estimates which are both statistically and practically different from ordinary least squares. 相似文献

“Strange thing—human relationships—for a Government to set up a Royal Commission on.” That is a comment I have heard more than once. It has been accompanied by an aloofness, a slight irritability, keeping the Report at arm's length and unread. That is from one section of the public. There are many other reactions. And there are our colleagues, many of whom have said how very important the Report is, and they have read it. Midway between these and other polarized viewpoints stands the Report itself, a long important essay in societal self-awareness. No wonder it has aroused much contradictory response. 相似文献

This paper examines the steady states of an overlapping generations economy with a given distribution of household locations over a one‐dimensional interval. Parents decide whether or not to educate their children. Educational decisions are affected by location: There are local complementarities in investment incentives stemming from aspirations formation, learning spillovers, or local public goods. At the same time, economy‐wide wages endogenously adjust to bring factor supplies into line with demand. The model therefore combines local social interaction with global market interaction. The paper studies steady‐state configurations of skill acquisition, both with and without segregation. The model is used to compare macroeconomic and welfare properties of segregated and unsegregated steady states. (JEL: D31, O15, D85) 相似文献

International study of heavy drinking: attitudes and sociodemographic factors in university students
Dantzer C Wardle J Fuller R Pampalone SZ Steptoe A 《Journal of American college health : J of ACH》2006,55(2):83-89
The authors studied the prevalence of heavy drinking among students in 21 developed and developing countries using an anonymous survey of 7,846 male and 9,892 female students aged 17 to 30 years. There were wide variations in the prevalence of drinking among countries, and the highest rates of heavy drinking (defined as 5 or more drinks for men and 4 or more drinks for women on at least 1 occasion over the past 2 weeks) were reported in Belgium, Colombia, Ireland, and Poland (men), and Ireland and England (women). Heavy drinking was associated with living away from home, having a wealthier family background, and having well-educated parents. Beliefs about the dangers to health of excessive consumption were negatively related to heavy drinking. Heavy drinking is a concern among students in several countries and is associated with greater affluence. Challenging beliefs concerning health risks is a crucial aspect of prevention in this population. 相似文献

The relationships between the consistency (CONS) principle and two other axioms, dummy (DUM) and independence of irrelevant strategies (IIS) for solution concepts on families of strategic form games are studied. If a solution satisfies DUM and IIS, then it
also satisfies CONS (Peleg and Tijs 1996). The converse of this proposition is not true: CONS implies neither DUM nor IIS
as shown in two simple examples, using the concept of coalition-proof Nash equilibrium. The axiom of weak dummy (WDUM) is introduced. WDUM, along with IIS, implies CONS. Moreover, CONS implies WDUM.

Marriage and family therapists (MFTs) use ethical codes and state licensure laws/rules as guidelines for best clinical practice. It is important that professional codes reflect the potential exponential use of technology in therapy. However, current standards regarding technology use lack clarity. To explore this gap, a summative content analysis was conducted on state licensure laws/rules and professional ethical codes to find themes and subthemes among the many aspects of therapy in which technology can be utilized. Findings from the content analysis indicated that while there have been efforts by both state and professional organizations to incorporate guidance for technology use in therapy, a clear and comprehensive “roadmap” is still missing. Future scholarship is needed that develops clearer guidelines for therapists. 相似文献

In the computation of two-sided confidence intervals for the binomial parameter p (using the binomial mass function), it is known that such intervals achieve a confidence coefficient that in general is not equal to the confidence level 1 – α, say. In this article we present some general results on the confidence coefficient and tabulate them for selected pairs (α, n = number of trials). We treat only the nominal equal tail probability case because it is the most commonly taught and used. 相似文献

The incidence of suicide is an example of rare event. A Cox cure model is adopted to examine the suicide risk of a cohort study of a sample of 65,000 Personal Emergency Link users over a 10-year observation period. Our objective is to investigate the effect of personal covariates on the failure time to suicide as well as the long-term survival from suicide. Based on the Cox cure model, a new and efficient estimation approach using retrospective sampling and multiple imputation was used. Compared with the standard Cox proportional hazards model, the Cox cure model provides a new perspective on analyzing the suicide data. 相似文献
