María José Suárez 《Review of Economics of the Household》2013,11(4):545-561
This paper aims to analyze household decisions regarding the childcare of young children. We present two specifications. The first one assumes a sequential decision process. Firstly, parents choose between paid or unpaid care and, secondly, those who opt for paid childcare must decide whether to take their children to a nursery or pre-school or employ somebody to care for them. The second specification is a multinomial Logit in which it is assumed that parents choose from three alternatives: unpaid care, paid care by a nanny, and center-based care. We apply our models to a sample of working mothers with children under three. The database used is the 2008–2010 Spanish Survey of Quality of Working Life (Encuesta de Calidad de Vida en el Trabajo). The results are in line with previous work: Parental education, family composition, income and the characteristics of the mother’s job are important factors in determining the type of childcare chosen for under-three-year-olds. 相似文献

This work analyzes the impact of remittances on nutritional status of children aged <5 years old in Ecuador in 2006. Using a set of anthropometric indicators constructed according to the new World Health Organization standards, the last household survey available for this country, and an instrumental variables strategy controlling for endogeneity of remittances, this study finds a positive and significant effect of remittance income on short-term and middle-term child nutritional status; nevertheless, no significant impact on long-run anthropometric indicators. 相似文献

Bayesian multivariate GARCH models with dynamic correlations and asymmetric error distributions 总被引:1,自引:0,他引:1
The main goal in this paper is to develop and apply stochastic simulation techniques for GARCH models with multivariate skewed distributions using the Bayesian approach. Both parameter estimation and model comparison are not trivial tasks and several approximate and computationally intensive methods (Markov chain Monte Carlo) will be used to this end. We consider a flexible class of multivariate distributions which can model both skewness and heavy tails. Also, we do not fix tail behaviour when dealing with fat tail distributions but leave it subject to inference. 相似文献

This paper brings together the research on temporary organizational forms. Despite a recent surge in publications on this topic, there have been few attempts to integrate knowledge on what we know of such temporary forms of organization. In order to correct this, an integrative framework is proposed around four central themes: time, team, task and context. Within each of these themes, the paper offers an overview of the literature, the gaps in what we know, and what future directions might be taken by scholars hoping to contribute to this important and rapidly growing field. 相似文献

Unions, particularly in Germany, are the subject matter of intense public debates as well as discussions in academic research, which corroborate the former. The last systematically conducted analysis of the status quo in academic research was done in spring 2001. In view of the rather dramatic symptoms of the crisis German unions are facing, it is time to incorporate the latest results of scientific research. This paper addresses this task against the background of a systematic literature review. Three application areas are distilled out of a total of 79 pieces of research that are considered relevant and intensively discussed: (1) the membership in German unions, (2) the unions in the German system of industrial relations and (3) the reformation of the German unions. The detected symptoms of the unions' crisis are impressively documented and explained by the studies. However, shortcomings regarding the respective research questions and the development of recommendations for future courses of action for the unions can also be identified. 相似文献

This paper considers the robustness properties in the time series context of the least median of squares (LMS) estimator. The influence function of the LMS estimator is derived under additive outlier contamination. This influence function is redescending and bounded for fixed values of the AR parameters. The gross-error sensitivity, however, is an unbounded function of the AR parameters. In order to asses the global robustness behavior of the LMS estimator, we consider several notions of breakdown. The breakdown points of the LMS estimator depend on the value of the underlying AR parameter. Generally, the breakdown point is below one half for high values of the AR parameter. The bias curves of the LMS estimator reveal, however, that the magnitude of outliers has to be considerable in order to cause breakdown. 相似文献

A Corporate Culture Pattern to Manage Business Ethics 总被引:2,自引:0,他引:2
Enrique Claver Juan Llopis José L. Gascó 《International Journal of Value-Based Management》2002,15(1):151-163
Within the general frame of proposals for an adequate management of business ethics, this paper is based on the vision of
corporate culture as a pattern to achieve such purpose. If we consider ethics as a specific value of corporate culture, we
may resort to the mechanism of cultural change and implementation in order to manage ethics. Despite the difficulties it entails
in terms of time and money investment, this procedure is one of the safest ways to reach ethical values which are known, shared
and then practiced by all the members of a corporation, whatever the category. From this central standpoint, and basing ourselves
on our own proposal for the management of culture, we shall describe which specific steps must be taken in order to achieve
a set of ethical values which are both realistic and furthermore shared by all collaborators of an organization.
