This paper evaluates the impact of a recent Norwegian family-policy reform. The reform provides benefits of up to NOK 3,000 (approximately € 400) per month to families with one- to three-year-old children, who do not utilize state-subsidized day-care centres. We investigate the reforms effect on parents labour force participation. We find that, on average, the reform reduced womens labour force participation and increased the specialization of work between couples. We find that the effect of the reform depends on womens schooling. Specifically, the labour force participation of highly educated mothers fell by more than that of mothers with less education.I am grateful to Associate Professor Espen Bratberg and Professor Alf Erling for their valuable comments. My special thanks to Kjell Vaage, Arild Aakvik and Afsane Bjorvatn for helpful suggestions. This paper was presented in a seminar at the Department of Economics, University of Bergen, Norway. I am thankful to the participants of the seminar for their positive feedback. The paper has also benefited from the reports given by three anonymous referees. I am also thankful to Professor Heather Joshi for helpful remarks on the paper. Responsible editor: Christoph M. Schmidt.  相似文献

Crucial to the long-term contribution of immigration to a receiving country's population is the extent to which the immigrants reproduce themselves in subsequent, native-born generations. Using conventional projection methodologies, this fertility contribution may be poorly estimated primarily because of problems in projecting the number of immigrants who are at risk of childbearing. We propose an alternative method that obviates the need to project the number of immigrants by using the full sending-country birth cohort as the risk group to project their receiving-country childbearing. This "sending-country birth cohort" method is found to perform dramatically better than conventional methods when projecting to 1999 from base years both before and after the large increase in inflows of Mexican immigrants to the United States in the late 1980s. Projecting forward from 1999, we estimate a cumulative contribution of Mexican immigrant fertility from the 1980s to 2040 of 36 million births, including 25% to 50% more births after 1995 than are projected using conventional methods.  相似文献

A decision maker has to choose one of several random variables whose distributions are not known. As a Bayesian, she behaves as if she knew the distributions. In this paper we suggest an axiomatic derivation of these (subjective) distributions, which is more economical than the derivations by de Finetti or Savage. Whereas the latter derive the whole joint distribution of all the available random variables, our approach derives only the marginal distributions. Correspondingly, the preference questionnaire needed in our case is less smaller.  相似文献

This paper focuses on the relationship between experiential and statistical uncertainties in the timing of births in Cameroon (Central Africa). Most theories of fertility level and change emphasize the emergence of parity-specific control, treating desired family size as both central, and stable across the life course. By contrast, this paper argues for a theory of reproduction that emphasizes process, social context, and contingency. The paper concentrates on the second birth interval, showing that it is longer and more variable among educated than among uneducated women. The paper argues that this difference is due to the specific forms of uncertainty associated with education in contemporary Cameroon.  相似文献

This article looks at the ability of a relatively new technique, hybrid artificial neural networks (ANNs), to predict Japanese banking and firm failures. These models are compared with traditional statistical techniques and conventional ANN models. The results suggest that hybrid neural networks outperform all other models in predicting failure for one year prior to the event. This suggests that for researchers, policymakers, and others interested in early warning systems, the hybrid network may be a useful tool for predicting banking and firm failures.  相似文献

The problems dealt with in this paper are generalizations of the set cover problem, min{cx | Ax b, x {0,1}n}, where c Q+n, A {0,1}m × n, b 1. The covering 0-1 integer program is the one, in this formulation, with arbitrary nonnegative entries of A and b, while the partial set cover problem requires only mK constrains (or more) in Ax b to be satisfied when integer K is additionall specified. While many approximation algorithms have been recently developed for these problems and their special cases, using computationally rather expensive (albeit polynomial) LP-rounding (or SDP-rounding), we present a more efficient purely combinatorial algorithm and investigate its approximation capability for them. It will be shown that, when compared with the best performance known today and obtained by rounding methods, although its performance comes short in some special cases, it is at least equally good in general, extends for partial vertex cover, and improves for weighted multicover, partial set cover, and further generalizations.  相似文献

Charisma, power and narcissism. On the diagnostics of an ambivalent leading qualityManagers are often obviously narcissistic personalities with “charismatic qualities”. The author discusses the background of these qualities and their ambivalence, because behind the brilliance of a successful manager may be a hidden narcissistic problem as the actual motive power. Nevertheless a constructive narcissism is to be distinguished from a destructive one. Charismatic constellations as well as narcissistic dynamics are to be understood not only as an individual problem but as an interactional phenomenon, involving both sides of a relationship. In order to explain these dynamics, the author presents the concepts of “narcissistic collusion” and “expanded self”. It is of great importance to the coach, to be able to analyse and to deal with these relational patterns — and also to preserve oneself from being involved in such narcissistic dynamics.  相似文献

Success factors of executive coaching. A screening of the coaching scenery from the client’s point of viewThis survey, based on questionnaires, examines the success factors of one-to-one coaching from the client point of view. Firstly, ten success factors in coaching were established by means of factor analysis. Secondly, more extensive analysis shows that, contrary to previous research in this field, the “professional system” is not necessarily a determining success factor in coaching. As an exclusive instrument of staff development, coaching seems to be effective even without support from the professional system. The analysis also indicates that the clients perceive their coach as an advisor and confidant as regards role expectations. Furthermore, multiple regression analysis discloses the predictive effects of the two success factors “the coach’s qualification” and “the coach’s involvement” for the overall success of coaching from the client’s point of view. The overall success of coaching itself is established through three items: the clients’ attitudes towards coaching, their attitude concerning further coaching, and the extent to which their objectives were met in coaching.  相似文献
