In this paper we analyse the impact of mothers’ employment status and formal child care attendance during early childhood on children’s school grades later in life, controlling for socio-demographic factors. We use the year 2008 of the Italian ISFOL-PLUS dataset. The dataset provides information on each respondent’s demographic characteristics, as well as a set of retrospective information on the individual’s school grades at the end of junior high school, high school, and university, along with (in the 2008 wave only) information about the respondent’s formal child care attendance and mother’s employment status when he or she was under age of three. We estimate the effects of maternal employment and child care attendance on the probability that the respondent would have high grades at the end of high school. Since maternal employment and child care attendance are likely to be endogenously determined, we use an instrumental variable approach. Our empirical results show that while having a mother who was working (during early childhood) had no significant effect on an individual’s high school grades, child care attendance had a positive and significant effect. These results have potential policy implications. As maternal employment does not seem to negatively affect the development process of children, while child care attendance appears to have a positive impact on academic achievement, policy makers should consider expanding the availability of child care and promoting women’s participation in the labour market. 相似文献

Summary. Census data are vital components of epidemiological studies, but the issues that are involved in using these data in such studies are often not fully appreciated. The paper describes some of the problems and uncertainties that arise, and some of the approaches that can be used to address them, based on experience in the Small Area Health Statistics Unit at Imperial College London. Issues considered include the geography of census data (zone design systems, recasting and the role of postcodes), temporal aspects of census data (especially in relation to migration and population change) and information content (especially in relation to characterization of socio-economic status). In the light of these issues, opportunities to improve the resolution and utility of census data for epidemiological studies are discussed. 相似文献

This study provides evidence on the relation between auditor tenure and audit quality. It is motivated by calls for mandatory auditor rotation, which are based on concerns that longer auditor tenure reduces auditor independence and thus audit quality. Earnings management is used as proxy for audit quality and is measured by absolute and signed performance-adjusted-Jones-model discretionary accruals. Multivariate analyses, controlling for additional firm and auditor characteristics indicate lower earnings management with longer auditor tenure. This result suggests that, in the current environment, mandatory limitations on the length of auditor-client-relationship would result in lower audit quality. 相似文献

Among the goals of statistical matching, a very important one is the estimation of the joint distribution of variables not jointly observed in a sample survey but separately available from independent sample surveys. The absence of joint information on the variables of interest leads to uncertainty about the data generating model since the available sample information is unable to discriminate among a set of plausible joint distributions. In the present paper a short review of the concept of uncertainty in statistical matching under logical constraints, as well as how to measure uncertainty for continuous variables is presented. The notion of matching error is related to an appropriate measure of uncertainty and a criterion of selecting matching variables by choosing the variables minimizing such an uncertainty measure is introduced. Finally, a method to choose a plausible joint distribution for the variables of interest via iterative proportional fitting algorithm is described. The proposed methodology is then applied to household income and expenditure data when extra sample information regarding the average propensity to consume is available. This leads to a reconstructed complete dataset where each record includes measures on income and expenditure. 相似文献

The aim of this paper is to analyse the relationship between the diffusion process of social representations of justice by the press and their appropriation by readers. Two simultaneous cross-sectional studies were carried out. Study 1 analysed the meaning and the frequency of the word justice in the most important newspaper in Buenos Aires. The results indicate that the representation of justice has a retributive and institutional meaning. Study 2 investigated university students’ social representations of justice (N = 404) through a word association technique. The results showed that the central core of social representation has a retributive and institutional meaning, similar to the representations diffused by the most important newspaper. Nevertheless, significant differences were found with regard to the value attached to justice depending on the newspaper that the participants claimed to read. We can conclude that there is a mutual constitutive circular movement between the social representation of justice diffused by the newspapers and university students’ social representations. Moreover, the differences identified in the way justice was evaluated in the peripheral elements might express the existence of different positionings related to a hegemonic social representation. 相似文献

This paper investigates the role of the extended parental leave in the return to work for mothers of newborn children. Exploiting
the variability in policies offered by the European countries, the paper studies the influence of statutory leave characteristics—length
of the job-protection and payments during the leave-period—on the hazard of returning to work at different ages of the child.
Results suggest that longer periods of job-protection increase the hazard of returning to work; on the other hand, providing
paid leaves increases the probability of remaining at home during the first year of life of the child. 相似文献

In this study, we investigate how economic agents choose gambling partners and how paired risky choices differ from individual
ones. To this aim, we develop a simple model and design a laboratory experiment that allows us to compare individual versus
paired decisions across two treatments, where pairs are, respectively, exogenously and endogenously formed. In both treatments,
paired subjects decide individually and independently how to allocate their wealth over a portfolio of lotteries and fully
commit to share any winnings. The main result from our experiment is that whenever agents are allowed to choose a gambling
partner they decide to team up with other agents who display the same degree of risk aversion as themselves. Moreover, paired
choices consistently involve higher risk taking than individual choices. This finding is more evident when information on
subjects’ risk attitudes is made available and when subjects team up in homogeneous pairs, thereby confirming that subjects
successfully exploit the benefits of mutual insurance. 相似文献

This paper investigates the economic effects on firms' policies of differences in law enforcement. We find that in judicial districts where trials are longer, bank financing is more costly and firms are smaller. However, we do not find any significant relation between law enforcement and firms' leverage ratio. We rationalize our results within a two‐ region dynamic general equilibrium model with asymmetric information and collateralized credit contracts. We find that a stronger enforcement of creditors' rights not only improves credit conditions (partial equilibrium effect), but also fosters individual capital accumulation (general equilibrium effect). In line with this theoretical prediction, we find a positive relation between individual savings and quality of legal enforcement. (JEL: E20, K40, G32) 相似文献

The impact of male-to-female intimate partner violence (IPV) research on participants is unknown. A measure of impact was given to participants in an IPV study to assess systematically the impact of completing questionnaires, engaging in conflict conversations, and being interviewed individually about anger escalation and de-escalation during the conversations. Participants completed a six-question, Likert-scaled impact measure. Both male and female participants rated the impact of the study as helpful to them personally and to their relationships. Female participants rated different segments of the study as more helpful to themselves and their relationships, while male participants did not find any segment of the study to have a different impact than other segments. 相似文献
