This paper explores, theoretically and empirically, the influence of interregional migration on regional fertility differentials. Specifically, it tests the hypothesis that regions that are closely linked through migration have, all else held constant, a lower differential in fertility than regions that are relatively isolated from one another. A model linking the fertility differential between two states to migration as well as a number of socioeconomic variables is articulated. The model is tested by means of a randomization procedure using U.S. state-level data for 1980. Results support the hypothesis that an increasing volume of interregional migration tends to lower regional fertility differentials.  相似文献

The Causes of Regional Variations in U.S. Poverty: A Cross-County Analysis   总被引:1,自引:0,他引:1  
The persistence of poverty in the modern American economy, with rates of poverty in some areas approaching those of less advanced economies, remains a central concern among policy makers. Therefore, in this study we use U.S. county-level data to explore potential explanations for the observed regional variation in the rates of poverty. The use of counties allows examination of both nonmetropolitan area and metropolitan area poverty. Factors considered include those that relate to both area economic performance and area demographic composition. Specific county economic factors examined include economic growth, industry restructuring, and labor market skills mismatches.  相似文献

The U.S. National Health Interview Survey (NHIS) is the world's longest survey time series of health data and a rich source of information on health conditions, behaviors, and care from the 1960s to the present. NHIS public-use files are difficult to use for long-term analysis, due to complex file structure, changes in questionnaire content, and evolving variable names and coding schemes. Researchers at the Minnesota Population Center have created the Integrated Health Interview Series (IHIS) to overcome these problems. IHIS provides access to thousands of consistently coded and well-documented NHIS variables on the Internet and makes it easy to analyze health trends and differentials. IHIS multiplies the value of NHIS data by allowing researchers to make consistent comparisons over half a century and thus to study U.S. health status as a dynamic process. This article describes the main features of IHIS and suggests fruitful avenues for historical research using these invaluable health data.  相似文献

第二次世界大战结束以后 ,美国对奥地利政策偏离了《莫斯科宣言》的方向 ,将奥地利作为被盟国解放的国家 ,反对追究奥地利的战争责任 ,极力推动奥地利的经济复兴和国内秩序稳定。美国国家安全委员会第 38 4号文件和第 1 6 4 1号文件乃是美国对奥地利政策的重要纲领。美国以奥地利只能向苏联支付实物赔偿和武装中立为条件 ,同意签署《奥地利国家条约》。促进奥地利的亲西方倾向 ,成为美国对奥地利政策的长期目标与重要特点。  相似文献

East Asia has led the world in economic growth and export expansion in recent decades. The phenomenal rate of economic growth among the so‐called “four little tigers”—Hong Kong, Singapore, South Korea, and Taiwan—enabled them to achieve newly industrializing country (NIC) status in the 1980s, followed by Indonesia, Malaysia, and Thailand. Earlier studies explained the development from the government‐led development paradigm, or the so‐called the statist approach. Scholars also argue that foreign direct investment (FDI) played an important role in the economic development, thanks to technology transfers. Kojima and Ozawa and later Kohama, however, argue that Japanese FDI help East Asian economies while U.S. FDI do not because Japanese technology transfer practices are appropriate for East Asian countries but not the United States'. Thus, we revisit the issue of East Asian economic development and test the economic effects of FDI from the United States and Japan. Using a Barro‐type growth model, we test the effects of FDI from the United States and Japan on economic growth in East Asian NICs. We find that FDI from both the United States and Japan helped economic growth in the “four little tigers,” but not in Indonesia, Malaysia, and Thailand.  相似文献

This report presents the results and assumptions of a set of projections of the population of the USSR, 1979-2025. Trends in population size and age-sex composition as well as fertility, mortality, and emigration are discussed. The detailed projection methodology is described in Kingkade (1987). The projections show that the population of the USSR will grow throughout the period to 2025. The working age population will grow very slowly for at least the next 10 years, and will not recapture the rapid growth experienced in the 1970s. The pension-age population will double in size between 1980 and 2025.  相似文献
