Single Parenthood and Children’s Reading Performance in Asia

Using the data from Program for International Student Assessment, I examine the gap in reading performance between 15‐year‐old students in single‐parent and intact families in 5 Asian countries in comparison to the United States. The ordinary least square regression analyses show negligible disadvantages of students with a single parent in Hong Kong and Korea, once students’ demographic characteristics and socioeconomic background are held constant. Students in single‐parent families in Indonesia and Thailand outperform their peers in intact families. The negative effect of single parenthood remains significant in Japan, even after parent‐child communication is controlled. Interpreting the weak effect of single parenthood in the Asian countries, I consider extended family systems and the relatively high proportion of widowhood among causes of single parenthood.     

Who is Appointed to What Position? The Politics of Appointment in Quangos of Korea

This study identifies the determinants of appointment of executives in quangos. Using data from 85 quangos in Korea over 15 years between 1993 and 2007, we investigate the degree to which various characteristics of organizational actors affect the choice of executives. Three organizational actors include presidents, sponsoring government departments, and the concerned quangos. Although results vary by executive position, the findings of the empirical analysis with multinomial probit and generalized linear mixed models support the idea that the appointment of quango executives is not the result of presidential choice but that of the interactions among the key organizational actors, with different incentives and resources, on the appointment. Compared to former bureaucrats, presidential allies are more likely to be appointed when presidents have more political support from the National Assembly and it is easier for insiders to be promoted as executives from larger and older quangos with clear legal origins.     

Top Team Diversity,Internationalization and the Mediating Effect of International Alliances*

This study examines the mediating effect of international alliances for the relationship between TMT (top management team) job‐related diversity (educational, functional background, outside industry experience and international exposure) and firm internationalization. We argue that firms with greater TMT diversity will use more international alliances, resulting in higher firm internationalization. Based on a sample of 226 US firms during the period 1988–1994, we find that international alliances partially mediate the relationship between TMT international exposure diversity and firm internationalization. However, we do not find international alliances to mediate the relationships between other forms of TMT diversity and firm internationalization. We discuss implications and directions for future research.     

Can Japan Become “A Society Attractive for Immigrants?” Identity,Gender and Nation‐States under Globalization in East Asia

Abstract: In 2003, the total fertility rate in Japan was 1.29. According to many predictions, if the current rate continues, the labor shortage will become critical. The Economic and Fiscal Policy White Paper, edited by the Cabinet Office ( Naikakuhu, 2003a ), stated “If we attempt to fill the lack by accepting immigrants in order to maintain the population of productive workers, we will need to accept 640 000 immigrants every year until 2050. It is necessary to make our country more attractive for foreign workers”. However, it is unlikely that more than 30 million immigrants will choose to live in Japan unless efforts are made to abolish xenophobia and to make qualitative changes that will change Japanese society so that it is more open to co‐existence. Moreover, Japan is not the only country that must worry about future declines in the work force and other countries will most likely start to attract foreign workers earlier than Japan ( Naikakuhu, 2003b ).     

International and Intersectoral R&D Spillovers in the OECD and East Asian Economies

This study empirically explores international and intersectoral R&D spillover effects on the total factor productivity growth of manufacturing and nonmanufacturing sectors based on a pooled time-series data set of 14 OECD economies and 3 East Asian economies—Korea, Singapore, and Taiwan. The study finds that foreign manufacturing R&D has strong influence on domestic productivity growths of both sectors and that domestic manufacturing R&D has a substantial intersectoral R&D spillover effect on domestic nonmanufacturing productivity growth. The social rates of return to manufacturing R&D are estimated to be two to six times greater than the private rates of return.     

SAMUELSON'S DICTUM AND THE STOCK MARKET

Samuelson has offered the dictum that the stock market is "micro efficient" but "macro inefficient." That is, the efficient markets hypothesis works much better for individual stocks than it does for the aggregate stock market. In this article, we review a strand of evidence in recent literature that supports Samuelson's dictum and present one simple test, based on a regression and a simple scatter diagram, that vividly illustrates the truth in Samuelson's dictum for the U.S. stock market data since 1926.(JEL G14 )     

Ridge Regression Estimation for Survey Samples

This paper describes procedure for constructing a vector of regression weights. Under the regression superpopulation model, the ridge regression estimator that has minimum model mean squared error is derived. Through a simulation study, we compare the ridge regression weights, regression weights, quadratic programming weights, and raking ratio weights. The ridge regression procedure with weights bounded by zero performed very well.     

Quantile Regression with Left-Truncated and Right-Censored Data in a Reproducing Kernel Hilbert Space

Li et al. (2007 Li, Y., Liu, Y., Zhu, J. (2007). Quantile regression in reproducing kernel Hilbert spaces. J. Amer. Statist. Assoc. 102:255–268.[Taylor & Francis Online], [Web of Science ®] , [Google Scholar]) developed an estimation method for quantile functions in a reproducing kernel Hilbert space for complete data, and Park and Kim (2011 Park, J., Kim, J. (2011). Quantile regression with an epsilon-insensitive loss in a reproducing kernel Hilbert space. Statist. Probab. Lett. 81:62–70.[Crossref], [Web of Science ®] , [Google Scholar]) proposed an estimation method using the ε-insensitive loss. This article extends these estimation methods to left-truncated and right-censored data. As a measure of goodness of fit, the check loss and the ε-insensitive loss were used to estimate the quantile function. The ε-insensitive loss can shrink the estimated coefficients toward zero; hence, it can reduce the variability of the estimates. Simulation studies show that the estimated quantile functions based on the ε-insensitive loss perform slightly better when ε is adequately chosen.
