This paper develops a Harris-Todaro (HT) type model of East-West migration in which labour market imperfections prevent market clearing in both blocs. The model encompasses two extremes of perfectly flexible wages with full employment on the one hand, and the HT scenario where the real wage in the host country is fixed, on the other. Welfare analysis compares the laissez-faire migration equilibrium based on explicit calculations of potential migrants without immigration controls in the West, with the socially optimal level of migration. The paper examines the issue of immigration control by developing a model of illegal immigration in which the incentives facing the potentially illegal immigrant are explicitly modelled.

This paper is inspired by a puzzling empirical fact that, despite the importance of controlling migration for their future, the host countries allocate very limited amounts of resources to the struggle against illegal immigration. The present model analyzes this issue in the context of low fertility in the host countries and suggests a novel channel though which the intensity of the struggle against immigration can be related to fertility. The analysis shows that, for childless individuals, who have no reason to care about the future, it is optimal to contribute less to the costly immigration-prevention measures.  相似文献

Australia is a major immigration country and immigrants currently represent around 28% of the total population. The aim of this research is to understand the long-term consequences of this immigration and, particularly, how migrants respond to opportunities within the country after arriving through the process of subsequent (internal) migration. The focus is on major immigrant groups in Australia, including persons born in the United Kingdom, New Zealand, China and India, and how their patterns differ from persons born in Australia. To conduct this analysis, we have gathered data for a 35-year period based on quinquennial census data. We also obtained birthplace-specific mortality data for constructing multiregional life tables for the immigrant populations. Subsequent migration is important for understanding population redistribution, and the relative attractiveness of destinations within host countries. Our results highlight the importance of subsequent migration and the diversity of migration behaviours amongst different immigrant groups in the context of overall declines in internal migration since 1981.  相似文献

The author describes the development of the population of the United States from independence to the present day in terms of its immigration history and related policies. Consideration is given to the existence of policies that discriminated against immigration by certain racial groups, and these are contrasted with U.S. internal migration policies, which always allowed unrestricted fertility and migration.  相似文献

In this discussion of Sweden as it approaches zero population growth, focus is on the following: population growth in perspective, fertility trends (childbearing concentrated and cohort versus period fertility), marital status (non-marital cohabitation, out-of-wedlock births, and divorce), women's changing status (increasing education and increasing employment), constraints and supports for women's dual role (family allowances and housing), birth control (contraceptive methods and practice and abortion), mortality trends, changing age structure and the elderly (average population age and proportion of elderly and cost of elderly support), international migration (from emigration to immigration and demographic impact of immigration), immigration policy, recent population debate (immigration issues and facing zero population growth). Since 1900 the primary features of Sweden's demographic history are a continuing decline in the birth rate to very low levels -- relieved by some upward movement in the 1940s and 1960s -- and a marked shift in the migration balance from emigration to immigration. It is almost entirely because of immigration that Sweden's population growth rate has not yet turned negative. If Swedish women were to continue to bear children at the rate that all women in the reproductive ages actually did in 1978, each women would end up with an average well below the level necessary to exactly replace each adult in the population leaving migration out, an annual total fertility rate of 2.1 children per woman would have to be sustained for births and deaths to be in balance under the low mortality conditions prevaling in Sweden.  相似文献

Concerns about population aging in Europe have occupied the attention of policy makers and demographers for over a decade. Some policy makers have proposed increased immigration to offset the aging of the population (i.e., replacement migration). However, demographers have estimated that a very high (and likely untenable) level of immigration would be required, and little is known about whether the national publics of Europe would support international migration as a potential solution to population aging. Using Eurobarometer data from 2006 and concurrent country-level measures from Eurostat, this study examines individual- and contextual-level factors related to public attitudes toward immigration as an effective solution to the problem of population aging in the current 27 member countries of the European Union. Results from multilevel logit analyses indicate that urban, university-educated, and childless individuals are consistently more likely than others to endorse replacement migration. Countries with more prosperous economies and proportionally fewer foreign-born residents also show more supportive attitudes. Such results echo research on anti-immigrant sentiment, suggesting considerable public resistance to population policies that might encourage large-scale immigration. At the same time, these findings show consistent patterns of endorsement despite demographers’ criticism of the concept of replacement migration and concerns about developing alternative long-term strategies.  相似文献

The 1990 Public Use Micro Sample is used to analyze the relationship between immigration and outmigration of the native born in New York City. The study population is limited to native born males who lived in the five boroughs in 1985. The relationship between immigration and the probability of various kinds of moves is assessed using logistic regression. Results suggest that immigration has an insignificant effect on migratory behavior, with the exception of inter-borough migration. Unlike prior work, this study examines a single metro area, and does not limit itself to inter-state migration. These results are consistent with more recent work (Card 2001; Kritz et al. 2001), which has failed to find a positive labor market level effect of immigration on native migratory behavior. The inter-borough finding is consistent with the occurrence of voluntary residential segregation within the city, in which the native born move away from areas of immigrant concentration but do not leave the labor market, yet there is no direct evidence that this process occurred.  相似文献

A critical evaluation of the available data on migration between India and Pakistan in the 1951-61 decade leads to the conclusion that there was a substantial net migration of Pakistan-born persons into India, but only a negligible net migration of India-born persons into Pakistan. Annual administrative statistics published by the Indian Government suggest an immigration from Pakistan of the order of 1.16 to 1.32 million. More importantly, birthplace data from the Indian censuses indicate a net intercensal immigration of Pakistan-born persons amounting to 1.19 to 1.34 million, depending on the assumed level of mortality. The Pakistani census data on the India-born show no net influx from India during 1951-61. Intercensal growth rates for the populations of different religious faiths in Pakistan are consistent with the estimates of net immigration into India. The migrants and the survivors of their progeny are estimated to represent a net gain of about 1.68 million by India and to account for no more than 2.2 per cent of the total population growth in India during 1951-61.  相似文献

This paper contributes to the immigration literature by generating two unique non-economic quality of life (QOL) indices and testing their role on recent migration patterns. Applying the generated QOL indices in conjunction with four independent welfare measures to an augmented gravity model of immigration, this paper finds an insignificant relationship between the six non-economic QOL measures and immigration flows for a panel of 16 OECD countries from 1991 to 2000. However, the results suggest that other factors such as the stock of immigrants from the source country already living in the OECD destination country, population size, relative incomes, and geographic factors all significantly drive the flow of immigration for the sample tested.  相似文献

改革开放以来,在制度改革和经济转型的双重作用下,我国人口迁移规模不断扩大,在影响迁移的因素当中教育水平是一个非常重要的影响。研究结果表明:教育在我国人口迁移过程中确实发挥显著的作用。从全国总体来看,教育对人口的迁入与迁出均呈现反向作用关系;城市教育水平与迁入及迁出也均呈现反向作用关系;然而,县教育水平与迁入及迁出均呈现正向作用关系。这反映出,我国目前的人口迁移是一种层级递进式的迁移情况。这种层级递进的模式实质上是我国城市化进程的反映,在这个过程中教育的作用不可忽视。  相似文献

Immigration and internal migration “flight”: A California case study   总被引:2,自引:0,他引:2  
Recent analyses of 1990 census migration data have pointed up disparities in the way immigration and internal migration contributions affect an area's demographic profile. They show that there is little overlap between states with large population gains from internal migration from other parts of the United States and states with large population gains from immigration from abroad. This emerging pattern, along with the fact that immigration and internal migration select on very different demographic characteristics, could lead toward a demographic balkanization of the nation's population. This paper evaluates immigration-induced out-movement from California, based on an analysis of recently released migration data from the 1990 U.S. census. The results presented here suggest that California's out-migration consists of two different migration systems: first, an immigration-induced flight that exports lower income and less-educated Californians, primarily, to the nearby states of Washington, Oregon, Nevada and Arizona. And second, a more conventional migration exchange with the rest of the United States that involves the redistribution of better educated, higher income migrants. It is the former migration system which appears to be most responsive to the low-skilled immigration flows, while the latter should be responsive to more conventional labor market employment characteristics. This implies that, irrespective of changing economic conditions in the state, the continued immigration of low-skilled migrants will lead to more losses of native-born internal migrants to neighboring states and metropolitan areas. However, these migrant streams will not be made up of the best and brightest residents that characterize most conventional migration streams.A longer version of this report with more extensive background statistics isResearch Report 94–306 (Frey, 1994b) available from Publications, Population Studies Center, The University of Michigan, Ann Arbor, MI 48104.  相似文献

Trends in international migration are presented in this multiregional analysis. Seven of the world's wealthiest countries have about 33% of the world's migrant population, but under 16% of the total world population. Population growth in these countries is substantially affected by the migrant population. The migration challenge is external and internal. The external challenge is to balance the need for foreign labor and the commitment to human rights for those migrants seeking economic opportunity and political freedom. The internal challenge is to assure the social adjustment of immigrants and their children and to integrate them into society as citizens and future leaders. Why people cross national borders and how migration flows are likely to evolve over the next decades are explained. This report also presents some ways that countries can manage migration or reduce the pressures which force people to migrate. It is recommended that receiving nations control immigration by accelerating global economic growth and reducing wars and human rights violations. This report examines the impact of immigration on international trade, aid, and direct intervention policies. Although migration is one of the most important international economic issues, it is not coordinated by an international group. The European experience indicates that it is not easy to secure international cooperation on issues that affect national sovereignty. It is suggested that countries desiring control of their borders should remember that most people never cross national borders to live or work in another country, that 50% of the world's migrants move among developing countries, and that countries can shift from being emigration to immigration countries. The author suggests that sustained reductions in migration pressure are a better alternative than the "quick fixes" that may invite the very much feared mass and unpredictable movements.  相似文献

West Germany and Switzerland have in general pursued similar immigration policies with respect to alien labor. In spite of a convergence in official policy and a change from temporary migration to settlement in both countries, immigrant groups in West Germany and Switzerland have displayed different attitudes and rates of integration within the host societies. Even when narrowing our discussion to one national group, the Italians, we find substantial differences persist. These cannot be attributed to the percentage of unskilled workers from Italy, intention to stay, the general social climate of the host societies, or even to political institutions such as trade unions. Rather, the higher integration and assimilation of Italians in Switzerland than in Germany appears to be related to structural and demographic factors. Unless policy-makers are aware of the importance of these factors, it is unlikely that they can adequately respond to the complexity and diversity of the problems generated by foreign workers.  相似文献

文章将雾霾污染卫星遥感数据与全国人口普查数据相结合,采用网络自相关和空间重力模型等方法,实证揭示了雾霾污染对人口迁移的影响。结果表明,(1)人口迁移存在明显的网络自相关效应,迁出地之间的空间集聚最为明显。(2)雾霾污染对人口迁入和人口迁出均存在显著的负向影响,雾霾污染每提高1%致使人口迁出和人口迁入分别下降0.297%和0.355%;收入水平和教育程度等因素是人口迁移中最显著拉力,高校生数量和气候等因素为人口迁移中最显著推力。(3)稳健性检验和异质性分析表明,雾霾污染对人口迁入和人口迁出均表现为显著的负向影响。基于此,雾霾污染并非当前人口迁移的关键动因,提高收入水平和教育程度仍是地区人才竞争中有力的杠杆,但随着"十四五"时期以人为核心的城镇化不断推进,雾霾污染将发挥更大的制约作用,应尽早关注雾霾污染给人口迁移带来的潜在挑战。  相似文献

Increasing realization of the implications of persisting below‐replacement fertility in Europe—shrinking absolute numbers combined with a rising proportion of the elderly—is giving new salience to policy considerations regarding immigration in the countries most affected by low fertility. The recent United Nations report on “replacement migration” (see the Documents section in the June 2000 PDR) highlighted the issue through illustrative calculations showing the size of immigrant streams that would be needed for achieving specified demographic targets in selected lowfertility countries, given continuation of present fertility and mortality trends. For example, the UN report suggested that in Italy—which has one of the lowest fertility rates in the world—maintaining a constant population over time would require a net influx of some 12.6 million immigrants during the next 50 years, and maintaining a constant labor forceage population (ages 15–64) would require a net inflow of 18.6 million. Yet immigration policy in Western Europe has become increasingly restrictive during the last quartercentury, and the official policy stance that regulating immigration is strictly within the domain of a country's sovereign right has been assiduously maintained. (International treaty obligations qualify that right in the case of bona fide asylum seekers; however, the definition of that category is also subject to the discretion of the receiving countries.) Thus, although within the European Union national borders are open to EU citizens, the power of regulating immigration from outside the EU is retained by the individual countries rather than subject to EU‐wide decisions. Suggestions coming from the developing countries to follow up the 1994 International Conference on Population and Development with an intergovernmental conference on international migration and development were set aside by the potential immigrant‐receiving countries as overly contentious. A statement by the Minister of Foreign Affairs of Italy, Lamberto Dini, delivered at the 55th General Assembly of the United Nations, 13 September 2000, may be a sign of a notable shift in official approaches to immigration policy by at least one EU member state. The statement, in a departure from the practice of touching lightly upon a wide range of issues in international affairs, typical in high‐level ministerial speeches given at that UN forum, is devoted essentially to a single topic: international migration. It characterizes migration “between or within continents” as an international problem and advocates “coordinated and integrated” instruments in seeking a solution. It suggests that “today, with a declining birth rate and an aging population, Europe needs a strategy that embraces the complex process of integrating people from different regions of the world.” The rules for international migration, the statement claims, should be set in a global framework, such as provided by the United Nations. In the “age of globalization,”“a solidarity pact is needed to find the best and most effective way of balancing the supply and demand of labor.” With the omission of opening and closing ceremonial passages and a brief comment on the problem of debt relief, the statement is reproduced below.  相似文献

This paper presents a stochastic model to forecast the German population and labor supply until 2060. Within a cohort-component approach, our population forecast applies principal components analysis to birth, mortality, emigration, and immigration rates, which allows for the reduction of dimensionality and accounts for correlation of the rates. Labor force participation rates are estimated by means of an econometric time series approach. All time series are forecast by stochastic simulation using the bootstrap method. As our model also distinguishes between German and foreign nationals, different developments in fertility, migration, and labor participation could be predicted. The results show that even rising birth rates and high levels of immigration cannot break the basic demographic trend in the long run. An important finding from an endogenous modeling of emigration rates is that high net migration in the long run will be difficult to achieve. Our stochastic perspective suggests therefore a high probability of substantially decreasing the labor supply in Germany.  相似文献

The paper challenges the view that the late twentieth century is the ‘age of migration’. For developing countries, flows of out-migrants are small compared with population growth, although in developed countries the stock of immigrants increased in proportion to the total population between 1965 and 1990. Despite the importance of refugee movement, the main force for international migration is economic. Why do not more people migrate (internally and internationally) to take advantage of potential economic gains? For international migration, one deterrent is institutional barriers against uncontrolled immigration. Different interest groups stand to gain or lose from increased migration. The income-enhancing effects of unhindered international labour migration, measured jointly for sending and receiving countries and by extension globally, should be very large. Even partial liberalization of immigration to industrialized countries would serve developing countries well. In industrialized countries, however, there is concern about the effect of massive labour inflows on the ethnic, religious and cultural composition of the population and its social cohesion. In some countries, migration is leading to greater ethnic mingling; in others there is a recrudescence of nationalistic aspirations for independent statehood with ethnically homogeneous populations, or to preserve the advantages of economically successful subregions.  相似文献

Immigration reforms in the United States initiated in the 1960s are widely thought to have opened the door to mass immigration from Asia and Latin America by eliminating past discriminatory policies. While this may be true for Asians, it is not the case for Latin Americans, who faced more restrictions to legal migration after 1965 than before. The boom in Latin American migration occurred in spite of rather than because of changes in US immigration law. In this article we describe how restrictions placed on the legal entry of Latin Americans, and especially Mexicans, set off a chain of events that in the ensuing decades had the paradoxical effect of producing more rather than fewer Latino immigrants. We offer an explanation for how and why Latinos in the United States, in just 40 years, increased from 9.6 million people and 5 percent of the population to 51 million people and 16 percent of the population, and why so many are now present without authorization.  相似文献

Recent analyses of the 1990 census migration data have pointed to the different demographic effects of internal migration and immigration. States and metropolitan areas either have large population gains through immigration or internal migration, but rarely both, leading to what has been labeled as an increasing demographic balkanization of the U.S. population. This paper explores the proposition that the internal migration of the foreign-born (pre-1985 arrivals) is likely to reinforce the demographic effects of immigration. Analysis is based on the five-percent Public Use Microdata file of the U.S. Census, with the demographic effects evaluated at both the state and metropolitan area levels. Distinctions were also made between nineteen separate national origin groups, increasing the detail of the analysis. Despite high internal migration rates and large net migration, there was little change in the overall distribution and concentration of the foreign-born population between 1985 and 1990. More important, however, distinctions were found across the national origin groups. While secondary migration leads to dispersion among some groups, other groups were becoming increasingly concentrated, suggesting that demographic balkanization of the American population is more variable than the literature would suggest.  相似文献
