Time or Money: The Relationship Between Educational Attainment,Income Contribution,and Time with Children Among Korean Fathers

Korean parents’ enthusiasm for and financial investment in children’s education are well known. However, parental time with children, particularly fathers’ time, and how it differs by parental education and income are not fully explored. Using the 2009 Korean Time Use Survey data, this paper examines how much time Korean fathers spend with children, how it differs by their education and income contribution to household, and which aspect Korean fathers choose to prioritize: time or money. In order to investigate a cross-couple effect, this paper also considers mothers’ time with children and their level of education. The sample is limited to married couples with the youngest child aged between 0 and 12. The stepwise multivariate regression analysis indicates that fathers’ education consistently shows a positive relationship with childcare time. Although fathers’ income contribution to household income has a negative effect on childcare time, positive effects of fathers’ education remain. Both mother’s education and childcare time increase fathers’ time with children. Korean fathers seem to juggle dual demands for money and time contribution and highly educated fathers tend to prioritize time over money. Given that time has become an important resource, different time investment in children by parental socioeconomic status may exacerbate social inequality.     

Dynamic mixing probability measures of mixtures

ABSTRACT

Lifetime of heterogeneous population can be modeled as mixture of a family of lifetime distributions according to a mixing probability measure. With the help of dynamic mixing measure, the hazard rate of the mixture can also be expressed as the mixture of the hazard rates of the lifetime distributions. Various local stochastic orderings are defined in this article. Applying these local stochastic orderings, we can explore the behavior of the dynamic mixing measures locally and then compare the hazard rates of two heterogeneous populations in both the local and global ways.     

Developing a Crisis Management Index: Applications in South Korea

The purpose of this study is to develop a crisis management index that can gauge a corporation's integrated crisis management capabilities. Although most crisis management models have been devised in Western countries, no full-scale crisis management index has been developed outside the Western hemisphere. This study deploys multiple research stages that reflect the characteristics of crisis management. First, the study validates index items through an extensive literature review, in-depth interviews, and professional audits. The dimensions of the index items are evaluated through an exploratory factor analysis and verified with construct validity through a confirmatory factor analysis. The final index dimensions—the organizational strategy, the organization system and culture, and the execution and communication—were applied to the case of South Korean corporations, and the implications based on their index scores are discussed.     

Stochastic comparison of generalized combined risk processes

Usually, two different types of shock models (extreme and cumulative shock models) are employed to model the dynamic risk processes. In extreme shock models, only the impact of the current fatal shock is usually taken into account, whereas, in cumulative shock models, the impact of the preceding shocks is accumulated as well. However, in practice, the effect of the corresponding shock can be realized in those two ways in one model (i.e., it can be fatal or, otherwise it is accumulated). This observation justifies the consideration of a ‘combined shock model’ in the risk modeling and analysis. In this paper, we generalize the study of the dynamic risk processes that were previously considered in the literature. The main theme of this paper is to find the optimal allocation policies for the generalized combined risk processes via the stochastic comparisons of survival functions. It will be seen that the obtained results hold for ‘general counting processes’ of shocks. In addition, we consider the problem of maximizing a gain function under certain risks and obtain reasonable decisions based on a variability measure. Furthermore, the meaningful explanations for the results on the policy ordering will be provided.     

A parametric approach for measuring the effect of the 10th revision of the international classification of diseases

Summary.  The World Health Organization revises the international classification of diseases about every 10 years to stay abreast of advances in medical science and to compare international health statistics. However, the new revision (i.e. the 10th revision) introduces discontinuities in mortality trends, making it impossible to compare the mortality statistics before and after the revision directly. The US National Center for Health Statistics published comparability ratios to correct the discontinuities between the two sets of mortality data: one coded by the ninth revision and the other by the 10th revision. We propose a parametric two-stage model to produce new comparability ratios and use these ratios to correct the discontinuities. The asymptotic behaviour of the comparability ratios is investigated. Our model not only measures the extent of discontinuities in trends in mortality but also can be used to forecast future mortality. Comparing with the National Center for Health Statistics's ratios, our comparability ratios smooth out the discontinuities better for most causes.     

Understanding Employment Discrimination: A Multilevel Approach

This paper reviews recent research on employment discrimination on the basis of sex, race, and ethnicity in US work establishments. Unlike blatant discrimination of the past, contemporary discrimination is typically more subtle, often unintentional, and develops in relationship to the social context in which it is embedded. Focusing on this covert and dynamic nature of discrimination, we review recent research that identifies factors at the individual, workplace, and societal level that contribute to variation in sex and race discrimination across employment contexts. At each level, we conceptually distinguish between factors that influence employers’ sex and race biases and factors that affect potential victims’ capacity to identify discriminatory experiences at work.

Stemming inequality? Employment and pay of female and minority scientists and engineers

When white men overwhelmingly dominated the science, technology, engineering, and mathematics (STEM) work force, the high pay in STEM occupations was a major source of gender and race inequality in the U.S. economy. As women, Blacks, and Latinos increasingly study STEM fields, new possibilities for achieving pay equality are opening. We test whether the reality matches the promise using two large data sets. Analysis of a five percent Public Use Microdata Sample (PUMS) of the 2000 Census and the 2001-06 American Community Surveys shows that women and minorities earn more, relative to comparable white men, in STEM than in non-STEM fields. This general pattern persists in analysis of a 1% sample of federal personnel records, which include better measures of work experience and education. Thus, federal efforts to increase the representativeness of the STEM workforce should increase pay equality in the economy by moving women and minorities into traditionally high-paying fields.
