Earnings assimilation of immigrants in Norway – A reappraisal

The relative earnings growth for immigrants in Norway is computed. Unlike Hayfron (1998, this journal) we define immigrants by country of origin rather than citizenship and perform separate studies of immigrants from inside and outside the OECD region. Replicating Hayfron op.cit. we find that the earnings assimilation is considerably weaker. Further, we find that the earnings of OECD immigrants are comparable to those of natives, while Non-OECD immigrants earn considerably less than natives at the time of entry, but that their relative earnings improve gradually over time. Earnings of different immigrant cohorts converged from 1980 to 1990, indicating a non-linear rate of assimilation. Received: 7 April 2000/Accepted: 4 January 2001     

Occupational and industrial contextual indicators in income determination models for Australia

Contextual variables, such as average education, gender composition, ethnicity and unionization, influence individual incomes differently when aggregated to occupations and to industries. Discriminatory effects exerted on income by ethnic and gender segregation in occupational labor markets are in some cases counterbalanced by segregation in industrial labor markets. Employment in different industries influences income irrespective of individual characteristics of the employees and irrespective of aggregate characteristics of their occupations. This impact of industrial location is also independent of organizational characteristics of the industries, even if the choice of characteristics is determined by the economic segmentation theory.     

Multigaussian models: The danger of parsimony

Summary MultiGaussian models have the intrinsic property of imposing very little continuity to extreme values. If the variable that is being modeled is hydraulic conductivity and the processes being studied are groundwater flow and mass transport, the absence of continuous paths of extreme values will have a retardation effect in the computed travel times. In the case of radionuclide release of nuclear waste from a deep geological repository, underestimation of travel times may lead to unsafe decision making. To demonstrate the impact of the low continuity of extreme value implicit to multiGaussian modes, travel times are computed in a site similar to Finnsj?n-one of the sites in crystaline rock studied in Sweden-using two stochastic models with the same histogram and covariance, one of them is multiGaussian, and the other is not and displays high connectivity of extreme high values. The results show that the multiGaussian model leads to less conservative results than the non-multiGaussian one. Invoking the parisimony principle to select a multiGaussian model as the simplest model that can be fully described by a mean value and a covariance function should not be justification enough for such selection. If there is not enough data to characterize the connectivity of the extreme values and therefore distriminate whether a multiGaussian model is appropriate or not, less parismonious models must also be considered.     

The time budget in socio-demographic statistics

The paper describes a Polish time budget survey conducted in 1976 on a rotation sample of the whole (non-agricultural and agricultural) adult population. Different time budget indicators are presented and their linkages with other statistical data and usefulness for social policy formulation and evaluation are discussed. Some new time indicators, not used in previous surveys, are recommended. Usefulness of time budged surveys for assessing an account of labor force and investigating of the social distribution of labor time as well as leisure time is underlined. The possibility of using time budget data for analyses of the social distribution of some welfare outlays in the field of cultural participation and consumption is also indicated. The paper is concerned with some methodological problems and the applicability of time budget research, rather than a comprehensive presentation of survey results.     

Note on the Cramér-Rao inequality in the nonregular case: the family of uniform distributions

We consider the family of uniform distributions with range of unit length. The main result of this note asserts that the average variance of any unbiased estimator of the midpoint of the range is not less than (2(n+1))(n+2))^-1 and this lower bound is sharp. The proof is based upon a nonregular version of the Cramér-Rao inequality.     

Demographic characteristics,work complexity and economic setting as social status determinants

Various aspects of social standing are significantly, though differently, determined by demographic characteristics, by employment in different economic sectors and industries, and by work complexity. Various sectors and industries influence differently status achievement, and are characterized by different configurations of status determinants of their workforces. The public (government) sector is more meritocratic than the private one, as far as income is concerned. Also, the male achievement pattern seems to be more meritocratic, while the female pattern is more sensitive to transient influences. The indicators of socio-economic status, occupational prestige and income reflect separate dimensions of social standing. The indicators of work complexity with data, people and things are good predictors of individual's social position.     

The Effect of a Family Policy Reform on Mother’s Pay: A Natural Experiment Approach

All parents in Norway with children aged one to three, who do not attend publicly subsidised day care, are entitled to a cash-for-care (CFC) subsidy. Studies have shown that the reform has reduced mothers labour supply. In this paper we analyse wage effects of the reform. We put forward a framework for evaluating reforms when reforms are uniformly and equally accessible nation-wide. First, running a simple Difference in differences (DD) analysis, results suggest that the CFC reform has reduced the mothers wages. However, after controlling for the age of the child effect, by running a triple difference approach, we no longer find any evidence of negative wage effects.This revised version was published online in May 2005 with corrections to the authors name and to the heading of table A2.     

Humankapitalbewertung bei der BASF Coatings AG – Eine anwendungsorientierte Modifizierung und Operationalisierung der Saarbrücker Formel mit dem Schwerpunkt der Wissensbewertung

The present paper describes the concrete application of an integrated Human capital measurement at BASF Coatings AG. For this purpose the Saarbrücker Formula has been broaden by factors that are of practical relevance. The resulting necessary adjustments in terms of definitions, delimitations and calculation logics of the Saarbrücker Formula lead to the extension and development of the approach. The so generated extended formula enables other companies to evaluate their human capital in a sensible way and to derive personnel-politically measures and therefore to overcome the gap between theory and praxis.
