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

Just as we have a turn around manager to save a failing business organization, so it is held, we need a turn around perspective to retrieve the Earth from being in a deficit position. Hence the paradoxical emphasis upon the Earth as the business of the future. Two important distinctions are offered which together provide a new frame of reference for bonding the human and the Earth. The initiating event for the first distinction was a business conference whose purpose was to explore the emerging domain of ego energy. In a parallel way, it is proposed we explore the yet to be discovered domain of eco energy. With eco energy we open our narrowed human window to cosmic perception. With cosmic perception, the energy of the universe can flow through us. The second distinction is between looking at and seeing. Looking at refers to treating our world as a collection of objects. As a collection of objects the Earth can be processed as a series of business transactions. With seeing we relate to our world as a communion of subjects. Such seeing offers transforming power for the human and the Earth to engage in the dialogue of powerful listening and speaking on both individual and planetary scale. These two sets of distinctions are sounded like echo chambers against ten ecologically guiding statements. These ten guiding statements become a reality-testing, experiential framework. Such a turn around perspective offers a different vision to be operationalized in our individual, community, and business lives. Then we can see clearly and respond with eco energy to the Earth, the business of the future!  相似文献

Natives often fear labor market competition of foreigners, as they may induce declining wages and rising unemployment as in the case of natives and immigrants being substitutes. However, there is also the potential that they are complements, producing positive wage and employment effects. This issue is examined in a framework with two types of labor, such that low qualified native and immigrant workers (blue collar), although substitutes for one another, are potentially complements to high qualified native workers (white collar). This is thought to accurately reflect the past West German immigration experience. Examining the wage functions of white and blue collar natives in a random effects panel model using a vast sample of micro data, we actually find that foreigners negatively affect the wages of Germans on the whole. Relatively small gains are made by white collar employees with less than 20 years experience, but these are outweighed by the larger negative effects experienced by blue collar employees.We wish to thank Don DeVoretz, Riccardo Faini, Andrea Ichino, and participants at the following 1993 conferences for their valuable comments where drafts of this paper were presented: The Economics of International Migration: Econometric Evidence at the University of Konstanz, Internationale Migration und Arbeitsmarkt der Schweizerischen Gesellschaft fur Statistik und Volkswirtschaftslehre at the University of St. Gallen, Adjustment Policies in Previously Centrally Planned Economies: Which Lessons from Developing Countries Experiences at the University of Brescia, and Congress of the European Society for Population Economics in Budapest. Substantial revisions were made following the valuable suggestions of two anonymous referees and the special issue editor Wolfgang Franz, for which we are grateful.  相似文献

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

Several criteria have evolved in law and tradition to constrain the delineation of Congressional and State and local legislative districts, such as population equality, geographic compactness, race/ethnic compactness, and integrity of political boundaries. Among the various criteria, I focus on compactness, and in particular, the legal and mensural aspects. Following the passage of the Voting Rights Act in 1965, racial compactness has been employed more and more frequently as a primary criterion, and with reduced restraint compared with other criteria, except perhaps for population equality. In Thornburg v. Gingles (1986), the Supreme Court recognized racial/ethnic compactness and polarization in voting practices as prerequisites for newly established majority-minority districts. In Shaw v. Reno (1993), the Court reaffirmed the principle of geographic compactness as against racial compactness by noting that the shape of Cong. Dist. 12 of North Carolina was bizarre and that it was drawn solely on racial grounds. With this decision, race/ethnic compactness and, by extension, the broad interpretation of the Voting Rights Act have been put in conflict with geographic compactness as criteria. More recently, in Miller v. Johnson (1995), use of race as a predominant factor in district delineation, apart from compactness, was rejected. These developments should renew interest in and support for formal statistical guidelines in evaluating geographic compactness in redistricting plans. Many formulas for measuring compactness have been proposed and tested. Here the commonly used perimeter/circle measure and the circumscribed area/circle measure are compared by an examination of some simple geometric figures and 1990-Census-based C.D.'s. Some problems with these measures are noted, and a new measure, the CV/radii measure (the complement of the coefficient of variation of the radii of the district), is proposed and illustratively applied.  相似文献

This paper proposes a simple method that analytically links the parameters and , which are not demographically interpretableand measurable in the Brass Relational Gompertz Fertility Model, with demographic measures of median age and interquartile range. We also extend the Brass model that deals only with age-specific fertility to age-parity-specific fertility, first marriage, divorce, remarriage, and leaving the parental home. The method has been successfully tested by fittings to 180 reliable observed demographic schedules in various countries and periods, and to nearly 10,000simulated schedules with various combinations of possible values (including the extremes) of and . Our proposed method that uses median age and interquartile range instead of and as input is useful in the population and family household projections. It releases the traditionalunrealistic assumption in population projections that the curve of the fertility schedule moves to the right or left in a parallel way. Instead, using our proposed method, one can assume that the demographic events would be delayed or advanced, while the curve becomes more spread or more concentrated, or, more specifically, assume that young people delay the events more than the older persons do, or vice versa. Our proposed method is also useful to formulate assumptions on future demographic trends for purposes of policy analysisand planning. It can be used to indirectly estimate demographic schedules when the detailed age-specific data are not currently available, which is useful for developing countries and sub-region studies in developed countries. A crucial point for a successful application of the method is that the standard schedule chosen can capture the general pattern of the demographic process in the population under study.  相似文献

This paper discusses how fishing communities around the world avoid destructive overfishing through local and largely informal self-management. The paper offers many examples that undermine the widespread assumption that the tragedy of the commons is inevitable without government regulation.  相似文献

During the 1990s, 23 states implemented family cap policies as a means to reduce the incidence of out-of-wedlock births among welfare recipients. Using Current Population Survey data from 1989 to 1999, we examine the impact of family cap policies on the birth rates of single, less-educated women with children. We use the first five states that were granted waivers from the Department of Health and Human Services to implement family caps as natural experiments. Specifically, we compare trends in out-of-wedlock birth rates in Arkansas, Georgia, Indiana, New Jersey and Virginia to trends in states that did not implement family caps or any other waivers prior to the Personal Responsibility and Work Opportunity Reconciliation Act. We employ several techniques to increase the credibility of results from our natural experiment, such as the inclusion of multiple comparison groups, controls for differential time trends, and difference-in-difference-in-differences estimators. Our regression estimates generally do not provide evidence that family cap policies reduce the incidence of out-of-wedlock births among single, less-educated women with children.  相似文献

When applied to monthly age specific data, Granger-Sims causality tests provide a useful technique for identifying the effective lag between business cycles and fertility in the United States. Male and female monthly age specific unemployment rates are used as a proxy for the business cycle, and test results are presented for first and higher order birth rates, as well as total age-specific monthly fertility rates. The period is subdivided (January 1958 – May 1973 and June 1973 – December 1984) in order to identify possible trends. Four results hold in all cases studied, with respect to the relationship between unemployment and fertility. (1) Noncausality is rejected in the direction from unemployment to fertility, and no feedback effect is indicated; thus the relationship is one of simple causality. (2) In the critical decision period from 9–16 months prior to realized fertility rates, the sign of the effect of unemployment on fertility is negative: this holds for both male and female unemployment rates. (3) There appears to have been a shortening of the effective lag between unemployment and fertility, of perhaps 2 – 3 months, between periods 1 (1959 – 1973) and 2 (1973 – 1984). (5) The strength of the (negative) relationship between unemployment and fertility appears to have increased from period 1 to period 2.Presented at the annual meeting of the Population Association of America, Chicago, April 30, 1987.

The imminent decline of populations in Europe, Japan and South Korea has generated widespread apprehension, largely because of fears that there will not be enough working age people to support the elderly. The UN Population Division has seemed to endorse those fears by an analysis of the levels of immigration needed to provide a constant number or ratio of workers, and by writing of the need for a solution to population decline. On the other hand, smaller populations would be environmentally advantageous in those countries. They must return to replacement level fertility or risk replacement by other populations, but they would benefit if they reached stationarity at a smaller population level. The transition is manageable if a higher proportion of working age people go to work. Right now, though dependency ratios are supposedly highly favorable, most of those countries are plagued by high unemployment levels.  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

Using Current Population Survey data, Vital and Health Statistics data, photoperiod data and temperature data, this article attempts to provide an interdisciplinary explanation of monthly (N = 243) variation in the dependent variable representing the birth rate (the rate of conceptions that become live births) for white women 20–24 years of age. Among the selected explanatory variables, four were found to play significant roles in accounting for the variation of the birth rate. They were rates of female absence from the labor market (nonparticipation plus unemployment), male employment rates, length-of-night variations and the days in the month of conception. Rainwater's concept of validating activities (1974) and recent quality of life research regarding domains serve as a basis for development of the concepts compensatory validation and contextual compatibility. Research and policy implications are discussed.  相似文献

A crucial debate in policy-making as well as academiccircles is whether there is a trade-off betweeneconomic efficiency and the size/generosity of thewelfare state. One way to contribute to this debate isto compare the performance of best cases ofdifferent types of state. Arguably, in the decade198594, the US, West Germany and the Netherlands were best cases best economic performers in whatEsping-Andersen (1990) calls the three worlds ofwelfare capitalism. The US is a liberalwelfare-capitalist state, West Germany a corporatiststate, and the Netherlands is social democratic in itstax-transfer system, although not its labor marketpolicies. These three countries had rates of economicgrowth per capita as high or higher than other richcountries of their `type, and the lowest rates ofunemployment.At a normative or ideological level the three types ofstate have the same goals but prioritise themdifferently. The liberal state prioritises economicgrowth and efficiency, avoids work disincentives, andtargets welfare benefits only to those in greatestneed. The corporatist state aims to give priority tosocial stability, especially household incomestability, and social integration. The socialdemocratic welfare state claims high priority forminimising poverty, inequality and unemployment.Using ten years of panel data for each country, weassess indicators of their short (one year), medium(five year) and longer term (ten year) performance inachieving economic and welfare goals. Overall, in thistime period, the Netherlands achieved the bestperformance on the welfare goals to which it gavepriority, and equalled the other two states on most ofthe goals to which they gave priority. This resultsupports the view that there is no necessary trade-offbetween economic efficiency and a generous welfarestate.The three panel studies are the American Panel Studyof Income Dynamics (PSID), the German Socio-EconomicPanel (GSOEP) and the Dutch Socio-Economic Panel(SEP). They all have samples of over 15,000 and arethe only national panels to have run for tenconsecutive years or more, so making it possible toassess the longer term performance ofwelfare-capitalist states.  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.

This study evaluates the social and demographic structure of poverty migration during the 1985–90 period based on an analysis of recent census data. Particular attention is given to the roles of two policy-relevant factors that are proposed to be linked to poverty migration. The first of these is the role of immigration from abroad and its effect on the net out-migration of longer-term residents with below-poverty incomes, from States receiving the highest volume of immigrants. Such a response, it is argued, could result from job competition or other economic and social costs associated with immigration. The second involves the poverty population magnet effect associated with State welfare benefits (AFDC and Food Stamp payments) which has come under renewed scrutiny in light of the impending reform of the federal welfare program. The impact of both of these factors on interstate poverty migration is evaluated in a broader context that takes cognizance of other sociodemographic subgroups, and State-level attributes that are known to be relevant in explaining internal migration. This research employs an exceptionally rich data base of aggregate migration flows, specially tabulated from the full migration sample of the 1990 US census (based on the residence 5 years ago question). It also employs an analysis technique, the nested logit model, which identifies separately the push and pull effects of immigration, welfare benefits, and other State attributes on the migration process. Our findings are fairly clear. The high volume of immigration to selected US Statesdoes affect a selective out-migration of the poverty population, which is stronger for whites, Blacks and other non-Asian minorities as well as the least-educated. These results are consistent with arguments that internal migrants are responding to labor market competition from similarly educated immigrants. Moreover, we found that the impact of immigration occurs primarily as a push rather than a reduced pull. In contrast, State welfare benefits exert only minimal effects on the interstate migration of the poverty population—either as pulls or pushes, although some demographic segments of that population are more prone to respond than others. In addition to these findings, our results reveal the strong impact that a State's racial and ethnic composition exerts in both retaining and attracting migrants of like race and ethnic groups. This suggests the potential for a greater cross-state division in the US poverty population, by race and ethnic status.Data Used: 1990 US census tabulations of full migration (residence 5 years ago) sample.

This paper deals with a full range of sexual and reproductive behaviors among different tribes of Gypsies in Serbia. The examined traits include rates of fertility, mortality, age distribution, education, crime rates, and parental care. In addition, Gypsy traditions of culturally prescribed sexual behavior are also studied. It is found that Gypsy tribes employ different reproductive strategies, ranging from an extreme, for humans, r (reproductive) strategy to a more typical K (parental) strategy. The reasons bringing about these differences come from the Gypsies' readiness to adjust their behavior and reproduction in order to create the most favorable strategy in a given environment. This paper elucidates and contrasts the more typical r-selected Gypsies with a group of K-selected Gypsies living in a Serbian village.  相似文献

This paper presents a typology and qualitative model of causation for use in assessing the relative contributions of population growth to problems of pollution, lost biodiversity, and natural resource depletion. Population growth is placed in context as one of eight key driving forces that shape environmental quality today. It is treated primarily as an impact amplifier, along with technology. Root causes are traced to paradigmatic beliefs—especially anthropocentrism and contempocentrism—which find expression in unsustainable consumption patterns and designs of political economy.  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

In a recent contribution to this Journal Anjomani and Hariri present an interesting study of United States interstate migration which explicitly incorporates so-called flow diversion and flow creation effects. Their discussion and evaluation of the model, however, are marred by several factors. This paper contrasts the roles of migrant stock and lagged migration in migration analysis and then addresses (a) the problems encountered when the family-friends effect is proxied with measures of lagged migrant flows, (b) the problem of using a two-period lagged value of earlier migrant flow as an explanatory variable, and (c) this paper suggests an alternative method of correcting the Anjomani-Hariri model's problems with multicollinearity.The author is grateful to Walter J. Wadycki and to David A. Macpherson for helpful comments and suggestions. The author, of course, bears full responsibility for all errors that remain. This research benefited from a grant from the Miami University Committee on Faculty Research.  相似文献
