This paper evaluates the impact of migrant remittances on human capital accumulation among youth. An augmented human capital model with two outcomes, education attendance and education attainment, is estimated using a large nationally representative household survey from Jordan. Empirical results show that migrant remittance receipt has a positive effect on education attendance. This finding is obtained while controlling for other socio‐economic determinants of schooling behavior and is robust to censorship and endogeneity bias. The results also indicate that the magnitude of the remittance impact on both education outcomes is larger for men compared with that of women.  相似文献

In manufacturing execution system (MES) projects, knowledge is heterogeneous and is applied partially in each software package. Consistency is therefore critical. Some standard business reference models exist, such as the IEC/ISO 62264 standard for MESs (also known as ISA S95), or the Supply Chain Operations Reference model for supply chain planning (SCP) and execution (SCE). These reference models have some overlaps. For example, traceability is part of both MES and SCE packages. A consortium of manufacturing software editors for industry has launched an ‘MES on demand’ platform using services from different packages. This paper presents the enriched business repository model built to facilitate business heterogeneity. It is used to align different business repositories (B–B alignment) and different business and software packages (B–S alignment). It likewise serves to align customer requirements with the repository (B–C alignment). The consortium platform is then ‘S95 compliant’ when knowledge supported by the different actors is included.  相似文献

Recently, several authors have been concerned with ordering comparison of known distributions of the family of generalized power series (GPS) distributions with their mixtures in various senses. In this article, we shall employ a unified approach and obtain similar results, more generally, for all members of the class of the GPS distributions. Some of the previous findings of Misra et al. (2003 Misra , N. , Singh , H. , Harner , E. J. ( 2003 ). Stochastic comparisons of Poisson and binomial random variables with their mixtures . Statist. Probab. Lett. 65 : 279290 .[Crossref], [Web of Science ®] [Google Scholar]), Alamatsaz and Abbasi (2008 Alamatsaz , M. H. , Abbasi , S. ( 2008 ). Ordering comparison of negative binomial random variables with their mixtures . Statist. Probab. Lett. 78 : 22342239 . [Google Scholar]), and Aghababaei Jazi and Alamatsaz (2010 Aghababaei Jazi , M. , Alamatsaz , M. H. ( 2010 ). Ordering comparison of logarithmic series random variables with their mixtures . Commun. Statist. Theor. Meth. 39 : 32523263 .[Taylor & Francis Online], [Web of Science ®] [Google Scholar]) in this connection, then, follow as corollaries. Further, we have derived some more ordering comparison results.  相似文献

Nonprofits have unique strategic concerns, including their dependence on external resources, the management of multiple stakeholders, perceptions about their organizational legitimacy as well as their primary focus on the social value of their organizational mission (Stone and Brush 1996). For shared Jewish–Arab organizations in Israel that are seeking to promote a ‘shared society,’ the obstacles in navigating these various challenges are particularly pronounced and require a very unique kind of adaptive capacity (see Letts et al. 1999; Connolly and York 2003; Strichman et al. 2007). Often operating outside of the general consensus, these organizations are faced with the significant challenge of promoting values of partnership, equality and mutual interests among two populations that are often at odds. This research seeks to shed light on how shared Arab–Jewish nonprofits are continually working to strengthen organizational capacities to more effectively carry out their particular organizational mission, given the myriad of challenges they face.  相似文献

Abstract. This paper shows that firm profits (and losses), and value added, are strongly related to individual hourly basic wages for most employees, as well as to the total earnings measures used previously but correlated with working time. Capital intensity is independently important without reducing the significance of profits, as in other studies. Value added avoids the negative bias implicit in accounting profits, and has a much larger effect on basic wages and earnings in the presence of numerous individual and firm controls.  相似文献

This study is the first to investigate the economic factors behind the recent rise of the one-child family in the United States. Using longitudinal data from the Panel Study of Income Dynamics (PSID) that runs from 1968 to 2013 and a variety of different model specifications with state and year fixed effect, including logistic regression, linear probability, and Cox proportional hazard models, the study examined the effect of absolute income volatility on the decision of having an only-child family. The study found that an increase in the standard deviation of income is associated with a decrease in the probability of having a second child for mothers who are in the second quartile of income distribution.  相似文献

Married individuals match with spouses who share their occupation more frequently than should happen by chance if marriage markets are large frictionless search markets covering a particular geographic area. This suggests that either there is a preference for same-occupation matches or that search costs are lower within occupation. This paper uses 2008–2015 data from the American Community Survey to analyze same-occupation matching among a sample of recently married couples. Our empirical strategy compares the difference in wages between same-occupation husbands and different-occupation husbands across occupations with different percent male workers. Under a preference explanation, this difference should become less negative as the share of males in the occupation increases. Under a search cost explanation, this difference should become more negative as the share of males increases. Our results are consistent with the search cost explanation. Furthermore, using an occupation-specific index of workplace communication, we demonstrate that the results are most consistent with the search cost mechanism for occupations with a greater degree of workplace communication. Finally, we show that matching on field of degree for couples in which both spouses have a college degree is also consistent with the search cost explanation.  相似文献

This article uses the Bangladesh famine of 1974 as a natural experiment to estimate the impact of intrauterine malnutrition on sex of the child and infant mortality. In addition, we estimate the impact of malnutrition on post-famine pregnancy outcomes. Using the 1996 Matlab Health and Socioeconomic Survey (MHSS), we find that women who were pregnant during the famine were less likely to have male children. Moreover, children who were in utero during the most severe period of the Bangladesh famine were 32 % more likely to die within one month of birth compared with their siblings who were not in utero during the famine. Finally, we estimate the impacts of the famine on subsequent pregnancy outcomes. Controlling for pre-famine fertility, we find that women who were pregnant during the famine experienced a higher number of stillbirths in the post-famine years. This increase appears to be driven by an excess number of male stillbirths.  相似文献
