U.S. Participation in the Development of a Transnational Database 2004-2007

卢森堡收入研究(LIS)项目是一个由多个国家组成的联盟，通过他们的NSF和其他研究资助者，合作资助一个研究和数据中心。在这里，LIS统一了每个国家收集的家庭收入微观数据集，并使用电子邮件将数据提供给全球的研究人员。全球400多名研究人员使用这些数据分析经济和社会政策及其对区域和群体特定收入结构、贫困和收入不平等、公共政策的政治支持、投票、生育率、移民、儿童福祉以及按教育水平和性别划分的工资和收入差距等主题的影响。定期活动，如赞助机构两年一次的会议和一年一度的夏季讲习班，与以数据库为基础的间歇性会议相结合。目前，有29个国家参加了LIS，还有其他几个国家(韩国、南非、土耳其、葡萄牙、希腊)正在加入。LIS目前有130多个数据库，每月还会增加更多的数据库(见www.lisproject t.org)。LIS已成为目前可获得的跨国家家庭收入分配数据和相关研究的最受尊敬的来源。因此，这项来自美国的核心资金提案，就像向其他29个国家提出的提案一样，对LIS项目的未来至关重要。未来三年的计划包括数据库管理方面的几项改进(更复杂的电子访问系统；非程序员的网络制表访问系统；更好的在线文档，第五波数据)；研究方面(不平等、贫困、性别研究等)；培训方面(在美国、欧洲和其他地方举行的LIS年度研讨会)。研究的目的包括为收入分配研究制定更好的购买力平价；增加一些发展中国家的数据并使其与富裕国家的数据进行比较；扩大LIS在政治经济学研究中的使用；衡量低收入对儿童福祉的影响；以及相关主题领域。该项目还开始了一项新的卢森堡财富研究，该研究与LIS平行，但基于10个国家的家庭财富调查。

The Luxembourg Income Study (LIS) project is a consortium of multiple nations which, via their NSF's and other research funders, cooperatively finance a research and data center. Here LIS harmonizes household income microdata sets collected by each nation, and employs electronic mail to make the data available to researchers across the globe. This data is used by over 400 researchers worldwide to analyze economic and social policy and its effect on such topics as regional and group-specific income structures, poverty and income inequality, political support for public policy, voting, fertility, immigration, child-wellbeing, and wage and earnings differentials by education level and by gender. Regular activities such as biennial meetings of sponsoring agencies and annual summer workshops are combined with intermittent conferences based on the database. Currently, twenty-nine nations participate in LIS, with several others (Korea,South Africa, Turkey, Portugal, Greece) in the process of joining. Over 130 data bases are now in LIS, with more being added every month (see www.lisproject.org). LIS has come to be the most respected source of cross-nationally available household income distribution data and related studies extant. And so this proposal for core funding from the US, like the proposals to the other 29 nations, is vital to the future of the LIS project.The plans for the next three years include several improvements in database management (more sophisticated electronic access system; web tabulator access system for non programmers; better on-line documentation, fifth wave of data); in research (inequality, poverty, gender studies, etc.); in training (annual LIS workshops in the United States, in Europe and elsewhere). The research aims include developing better purchasing power parities for income distribution studies; adding a number of developing nations data and making them comparable with rich nations data; expanding the usage of LIS in studies of political economy; measuring effects of low income on child well being; and related subject areas. This project is also beginning a new Luxembourg Wealth Study which is parallel to the LIS but which is based on household wealth surveys in 10 nations.
