This paper examines the twentieth-century population recovery of Native Americans with reference to urbanization, intermarriage, and differing definitions of the Native American population from census and tribal enrollment data. The recent increase in the Native American population reflected in regular US decennial censuses since 1960 is discussed in terms of changing self-identification of individuals as Native American. Also discussed are criteria for enrollment in Native American tribes, particularly blood quantum requirements. Census enumerations are compared with tribal enrollment data, and it is illustrated that a large proportion of those identifying as Native American in the census are not enrolled in Native American tribes. Special attention is given to how Native American tribal enrollment criteria might impact future population size.  相似文献

The concept of demographic efficiency is proposed and data envelopment analysis (DEA) is introduced as a method for determining which countries are demographically efficient. While the purpose of the paper is primarily to introduce the concept and the method, several simple examples are used for purposes of illustration. The first two explore how efficiently countries have converted their level of development (the input) into male and female life expectancy at birth (the outputs). The second two reverse the postulated relationship, treating life expectancies as inputs reflecting general health status of a population, and level of development as the output. Countries are said to be efficient if they have achieved the maximum output observable for a given level of input, or if they have minimized the inputs needed to achieve a prescribed level of output. Together, the efficient cases form an efficiency frontier. DEA, a form of linear programming, also permits the degree of inefficiency of countries lying behind this frontier to be measured by calculating the extent of the output slacks that are present. Output slacks are the shortfalls in the level of performance that could have been achieved given the inputs available, and may themselves be treated as independent variables in explorations of the sources of demographic inefficiency. One example of such an exploration is offered—an attempt to account for shortfalls in female life expectancy, given levels of development.  相似文献

Has the relative unemployment propensity for the low-skilled increased during the 1990s? We address this question empirically, based on two notions of low skills; i) low education, and ii) low ability, conditioned on education and work experience. Ability is identified by previous earnings. Evaluated by the education-based measure, we find that unemployment propensity has not developed unfavourably for the low-skilled. Evaluated by the ability-based measure, it has. We uncover a steady deterioration of employment prospects for persons with low ability relative to others with similar formal qualifications. The adverse employment effects of being low-skilled are stronger the higher is formal education.All correspondence to Knut Røed.

The paper develops a model of family size decisions in which couples choose explicitly a combination of mother's time and purchased childcare (e.g. childminders, nannies) for the care and rearing of children. The theoretical model implies that the impact of the mother's wage on her completed fertility varies with the market price of childcare, and that this effect increases (becoming less negative or more positive) with the level of her wage. Econometric analysis of British micro-data confirms the main predictions of the model.I am grateful to Robert E.

Using individual-level survey data that were collected in Russia in 1993, we analyze the fertility-employment relationship for a sample of urban women who bore children during the Soviet era. Although some Russian policy makers advocate policies that reduce female employment to stimulate fertility, we find little empirical support to ensure success of these policies. Specifically, we find no connection between employment and fertility for our sample of Russian females, perhaps because of their historic, mandated commitment to the labor market. Instead, we find that demographics and attitudes influence fertility decision making. These results, in combination with the findings that our sample of Russian women hold more traditional attitudes toward family and egalitarian attitudes toward work than similar American women, suggest that policies to stimulate fertility by reducing employment may not be effective for women raised during the Soviet era unless a dramatic shift in attitudes away from a strong work commitment also occurs.  相似文献

Using data from China's One-Per-Thousand Fertility Survey conducted in 1982, a cohort analysis is carried out to estimate the demographic consequences of the later marriage policy implemented in the People's Republic of China. The findings show that the later marriage policy had a strong positive effect on mean age at first marriage and first birth but a negative impact on the length of the first-birth interval, suggesting that the depressing effects on fertility of the administratively enforced postponement of marriage are more or less offset by adjustments over the first-birth interval by Chinese couples.  相似文献

Thirty social indicators, consisting of crime rates and variables which may be regarded theoretically as correlates of crime, are factor analyzed for 729 incorporated American cities with a minimum population of 25000. Factors associated with crime, poverty, native-born status, city revenue, residential stability, home construction, city size, and population age are identified. The data matrix is partitioned in order to identify high crime and low crime cities. The cities in each category are then subjected to cluster analysis on the basis of the seven socioeconomic factors, and the resulting groups are investigated further in order to identify distinctive clusters and underlying patterns of social conditions. A group of model low crime communities is identified — virtually all were incorporated white noose suburbs of metropolitan areas. Residential instability and large population size are associated with two of the high crime groups, which include stereotypical crime problem cities such as Detroit, Chicago, and Kansas City. The member cities constituting each of the eight groups are documented, and the policy implications of the findings are discussed.  相似文献

Endogenous population growth, i.e., making the rate of population growth dependent on society's opulence, causes parametric changes to have a larger impact and can cause multiplicity of steady states in a dynamic intertemporal optimization framework. This provides a simple explanation for the possibility of differing growth paths between countries (using a standard production function) or another explanation of the poverty trap. We give two examples (opulence sensitivity and production sensitivity) that both give rise to three steady states in which poor (rich) countries will evolve over time to the low (high) income steady state. In both examples there are middle income countries that will choose the low (high) income steady state if they are impatient (patient), where patience is measured through the rate of time preference o. Foreign aid in the form of a large transfer of capital from abroad enables poor and impatient middle income countries to move to the high income steady state.We would like to thank Nico Heering, Martijn Herrmann, Theo Junius, Ngo van Long, Ad Pikkemaat, John Pitchford, Lakshmi Raut, Casper de Vries, an anonymous referee, participants of workshops at the University of Groningen and the University of Amsterdam and especially Harry van Dalen for valuable comments.

The Earths surface has changed considerably over the past centuries. Since the start of the Industrial Revolution in the early 1700s, humans from the Old World started to colonize the New World. The colonization processes lead to major changes in global land use and land cover. Large parts of the original land cover have been altered (e.g., deforestation), leading to extra emissions of GHGs to the atmosphere and enhancing global climate change. The spatial and temporal aspects are still not very well known. More and more global integrated environmental assessments concerning global sustainability require long time series of global change indicators, of which population is an important one. This study presents an update of the geo-referenced historical population maps for the period 1700–2000, part of the History Database of the Global Environment (HYDE), which can be used in integrated models of global change and/or global sustainability.  相似文献

This paper reports a multi-stagestudy carried out between 1999 and 2001 whichaimed to develop an instrument to address theneed for a culturally relevant measure ofquality of life for Chinese older persons inHong Kong and similar communities. The firststage of the research involved a focus groupstudy conducted in August 1999 which it washoped would reflect how quality of life maybe interpreted by older persons themselves. Thenext stage, a content analysis of the focusgroups, enabled the construction of aquestionnaire containing over 100 items onvarious aspects of quality of life (QoL). Thequestionnaire was reviewed by a panel ofexperts and the items were refined and reducedto 86 to which were added a further 25 itemsfor socio-demographic background. This formedthe initial instrument. The final stage was avalidation study based on a representativecommunity survey, with a sample of 3,000respondents drawn for the research team by theCensus and Statistics Department of the HongKong Special Administrative Region (HKSAR)Government. The survey yielded 1,616 successfulinterviews with older persons aged 60 or above.The careful stratification of the sampleenabled us to say that subjects in all thestages of the survey had broadly similarcharacteristics to the general Hong Kongelderly population in sex and age distribution.After a rigorous process of validation, theresearch team recommended the adoption of bothan index and six domains for measuring HongKong older persons QoL. The new scale containsa total of 21 items which can be grouped intovarious domains: subjective well-being, with 4items; health with 5 items; interpersonalrelationships with 6 items; achievement-recognition with 4 items, finance and livingconditions (1 item each). The overall QoL scalehas a Cronbachs alpha of 0.72 with its domainsranging from 0.65 to 0.77 which indicates ahigh degree of statistical reliabilities. Thename recommended for the scale was Hong KongQuality of Life for Older Persons Scale-abbreviated as HKQoLOCP.  相似文献

The crucial challenge for integrated analyses of socioeconomic systems is keeping coherence in their multidimensional representation. Our approach describes the hierarchical structure of socioeconomic systems using the profile of allocation of human activity over a set of compartments defined at different hierarchical levels (e.g., whole countries, economic sectors, individual households). Compartments are characterized in terms of intensive variables (intensity of both exosomatic energy flows and added value flows per unit of human activity) and the extensive variable Total Human Activity population. In this way, relations of congruence across hierarchical levels can be used to link non-equivalent analyses. That is, changes in demographic variables, economic variables, technical coefficients, indices of environmental loading, institutional settings, and social aspirations are no longer independent of each-other even if described within different scientific disciplines.  相似文献

We simulate the effect of the introduction of premium differentiation (experience rating) in the Dutch Unemployment Insurance system on the demand for labor for a variety of sectors in the Dutch economy. For the simulations we use the Bentolila and Bertola (1990) framework as a point of departure. In the simulations, the introduction of experience rating is modeled as expenditure neutral: in the absence of premium differentiation the cost of financing UI is modeled as a wage tax (independent of the number of workers fired by the firm), whereas in the presence of experience rating this cost is attributed to firing cost (affected by the firing action). Thus, the introduction of experience rating results in a shift from wage cost to firing cost. Following the political debate on the issue in the Netherlands, we assume that the introduction of experience rating does neither lead to a change in tax rates paid by workers nor to a change in eligibility rules or replacement rates of benefit claimants. Specific attention is paid to the distinction between young and old workers . In the model, labor adjustment costs (hiring and firing costs) are linear. The model allows for uncertainty in the business cycle.All correspondence to Hans Bloemen. Responsible editor: Alessandro Cigno  相似文献

Against the backdrop of occasional claims by social scientists that class analysis is no longer relevant this article will study the consumption patterns of different classes. Two hypotheses are derived and tested. These are to assume that classes' consumption differences are due to processes of social closure, or are of a cultural kind. This is investigated using a Swedish family expenditure data-set from 1992. The focus is on classes' different uses of their incomes regarding basic expenditures, expenditures on non-durables and ownership of durables. The most striking result is that 'higher' classes tend to spend a great deal of money on activities outside the home, 'appearance' and information, while other classes' consumption resembles the 'higher' classes, to different degrees. Moreover, the class hierarchy, constructed theoretically from employment factors, resembles a hierarchy constructed from similarities in patterns of consumption. The main conclusion is that class matters, in interesting ways, for consumption, though there are also other powerful factors. The closure hypothesis receives support, even though a combination of the two hypotheses seems sound.  相似文献

We study a dual economy model of growth and unemployment in the presence of Harris-Todaro type labor migration. The model is a discrete time model of economic growth with given population but endogenous migration of labor. The economy tries to reach development in the quickest possible time while not allowing unemployment to rise above a socially acceptable level. We characterize situations under which maximizing the accumulation of capital in each period is optimal. We also study how particular taxes and subsidies affect unemployment and capital accumulation. Finally, we show that a higher initial capital stock does not necessarily mean a quicker attainment of self-sustained full employment.  相似文献

Since July 1997, Hong Kong has become a Special Administrative Region (SAR) under the sovereignty of China. This paper compares the social well-being of Hong Kong residents before and after the change of sovereignty by analyzing six sets of survey data collected between 1990 and 2001. These are six biennial territory wide Social Indicator Surveys conducted to collect subjective assessments of well-being of Hong Kong residents. Analysis of the survey data which are typically categorized subjective evaluations has to deal with the commonly encountered problems of direct quantification (Schuessler and Fisher, 1985) and incomplete data (Little R.J.A. and Rubin D.B., 2002, Statistical Analysis with Missing data (Wiley-Interscience, New Jersy). The problems are handled by applying optimal scaling and hot-deck imputation as recommended by Shen S.M. and Lai Y.L. (2001, Social Indicators Research 55, pp. 121-166). Different life domain measures as well as compound measures in the form of indices are studied. The data analysis indicates that the residents of Hong Kong were most satisfied in 1997 and least satisfied in 1995. It reveals that the sovereignty change had major impact on many life domains of the people of Hong Kong and the effect was compounded by the economic situation of the territory.  相似文献

The relationship between AFDC, Food Stamp, and Medi-Cal Program eligibility, on the one hand, and labor force participation, on the other, was analyzed by comparing the labor force participation rates of women of Mexican origin who were fully eligible for these programs with those of less eligible women. Marital status, husband's income, and legal residence in the United States were used to define levels of program eligibility for this sample. The effects of education, English fluency, age, the number and ages of children, and the number of other adults in the household (excluding the mother and spouse) were controlled in logistic regression procedures. The results of the multivariate analyses show that AFDC, food stamps, and Medi-Cal combined inhibit the labor force participation of unmarried mothers. There is no evidence, however, that food stamps and Medi-Cal influence the labor force participation of married mothers. Earnings information on this sample of California women indicate that welfare benefits for unmarried mothers are highly competitive with net earnings, primarily because of the cost childcare. The data imply that free or subsidized childcare would increase labor force participation and reduce AFDC enrollment.  相似文献

The nations of the Middle East have arrived at a historic crossroad.Anchored in centuries-old political and economic systems, bitterethnic rivalries, recurrent intra-regional warfare, and risingfundamentalism, the majority of the regions countries haveremained largely apart from the transformative processes that areshaping development in other world regions. Indeed, the impressionexists that no development miracles are occurring in theMiddle East and that, to a very great extent, the region isseeking to remain on the sidelines of modern history. And,yet, if the countries of the Middle East are to flourish in thenext century they, too, must restructure themselves for dealingwith the complex realities associated with increasing globalizationand internationalization. This paper reports on the socialdevelopment successes and failures of 22 Middle Eastern countriesbetween 1970 and 1997. Also identified are the regions SocialLeaders (SLs), Socially Least Developing Countries (SLDCs),and Middle Performing Countries (MPCs). The social, political,and economic factors most closely associated with each countrysdevelopment classification are identified.  相似文献

The restructuring of financial markets and financial institutions through bank mergers has been accompanied in many countries by concerns about the resulting `geography of finance. In Canada, two proposed mergers involving four of the largest banks have raised concerns about the possibleimpacts of the proposed mergers on the access to financial institutions in rural Canada. This paper assesses the potential impact of the proposed mergers on the geography of finance in rural communities in British Columbia. The methodological choices which must be made to frame such an anlysis are discussed and include choices related to the definitions of `accessibility, the `industry, a `competitive industry, a `bank branch and a `community. A new Index is devised to measure the vulnerability of rural communities to post-merger bank branch closures. It is concluded that the bank mergers will, if approved, have significant negative impacts for the accessibility of the banking system in rural British Columbia. It is also suggested that Canada needs to examine establishing a wider regulatory framework which addresses the issue of accessibility on a longer term basis.  相似文献

The effects of labour supply growth on the welfare of preexisting destination and non-emigrating source populations are analysed. This growth occurs in open economies where free trade in capital goods is possible. Traditional small economy arguments for population growth rely on the existence of priced though internationally immobile factors. When all factors are freely-traded and population grows naturally the case rests either on market distortions or common property within families. In an integrated world labour growth can lead to capital flight and increasing wage differentials. With international interactions, immigration increases preexisting welfare in destination countries but generally (not always) reduces it for non-emigrants in source countries. Immigration provides efficiency gains to all originally resident in source countries. Natural population growth anywhere promotes efficiency gains everywhere.  相似文献
