This paper proposes an overlapping-based test statistic for testing the equality of two exponential distributions with different scale and location parameters. The test statistic is defined as the maximum likelihood estimate of the Weitzman's overlapping coefficient, which estimates the agreement of two densities. The proposed test statistic is derived in closed form. Simulated critical points are generated for the proposed test statistic for various sample sizes and significance levels via Monte Carlo Simulations. Statistical powers of the proposed test are computed via simulation studies and compared to those of the existing Log likelihood ratio test. 相似文献
Muslims constitute 2.2% of the Australian population. Given the current socio-political climate and the limited research, the present exploratory study explores the relationship between acculturation, ethnic identity, self-identity, generational status, religiosity, and demographics among adult Australian Muslims.
A cross-sectional convenience sample of 324 adult Australian Muslims completed either online or paper-based questionnaires in either English or Arabic. Recruitment was via convenience sampling and social media advertisements. Acculturation, ethnic identity (MEIM), religiosity, and demographic variables were measured.
The study sample was young and mostly female, with high religiosity levels. Acculturation was negatively correlated with ethnic identity. From multiple regression analysis, acculturation was predicted independently by religiosity (low), age (young), gender (male) and ethnic identity (low).
First generation Australian Muslims were older, had stronger ethnic identity and religiosity, and more commonly self-identified as non-Australian. By contrast second- and third-generation were more likely to self-identify as bicultural or Australian.
In summary, acculturation of Australian Muslims is influenced by multiple variables, particularly ethnic identity, religiosity, and generation; hence all these variables need to be included in policy regarding successful integration of migrants. 相似文献
Raising employment, in particular employment among older individuals and low educated individuals, stands high on the agenda of policy makers in many OECD countries. Increased sensitivity in recent years to rising inequality has made the challenge only larger. In this paper we evaluate alternative fiscal policy scenarios to face this challenge. We construct and use an overlapping generations model for an open economy where individuals differ not only by age, but also by innate ability and human capital. The model allows us to study effects on aggregate employment, per capita income and welfare, as well as effects for specific age and ability groups. We show that well-considered fiscal policy changes can significantly improve macroeconomic productive efficiency, without increasing intergenerational or intragenerational welfare inequality. Our results strongly prefer a reduction in the labor tax rate on older workers and on all low-wage earners, financed by an overall reduction in non-employment benefits. An alternative financing option is to raise the consumption tax rate. These results are to be seen as long-run effects for economies at potential output. 相似文献
Research into European identity has mostly focused on majority populations in Western European countries, neglecting new member states in Central and Eastern Europe (CEE) as well as ethnic minority groups. This paper contributes to filling this gap by exploring and investigating processes of European identity formation of five ethnic minority groups in four CEE countries. A generational perspective was applied by conducting qualitative in-depth interviews with three generations of ethnic minority group members. The results support the instrumental approach of identity construction. In all minority groups researched, the young generation, due to more positive personal experiences and perceived benefits from the European Union, have developed more positive images and perceptions of Europe and a greater sense of European identity than older generations. Furthermore, ethnic group-specific processes of identity formation were found. 相似文献
The article reconsiders the implications of the choice of pure social time preference for intergenerational equity in the
presence of a time-consistent utilitarian social welfare criterion. The analytic framework is a setting with overlapping generations,
lifetime uncertainty, population growth and technical progress. The analysis identifies upper and lower bounds for the feasible
range of social discount rates and draws a corresponding distinction between “gerontocratic” and “Stalinist” optimal plans.
