Extensive and Intensive Margins of Exports and Labor Heterogeneity

This paper investigates how changes in skilled and unskilled labor supply affect different margins of exports. Using bilateral trade data in manufacturing sectors of 34 countries from 1995 to 2010, we find that most of the impact of skilled labor on exports goes through the intensive margin, whereas most of the effect of unskilled labor works through the extensive margin. These outcomes result from the impact of labor skill composition on the productivity cut‐off of exporters. We also find that the impact of skilled and unskilled labor on trade margins depends on the income level of countries and on the type of products. The results indicate that the effect of skilled labor is greater for low‐income countries and differentiated products, while that of unskilled labor is greater for high‐income countries and homogeneous products.     

Dynamic factor long memory volatility

In this paper, we develop a long memory orthogonal factor (LMOF) multivariate volatility model for forecasting the covariance matrix of financial asset returns. We evaluate the LMOF model using the volatility timing framework of Fleming et al. [J. Finance, 2001, 56, 329–352] and compare its performance with that of both a static investment strategy based on the unconditional covariance matrix and a range of dynamic investment strategies based on existing short memory and long memory multivariate conditional volatility models. We show that investors should be willing to pay to switch from the static strategy to a dynamic volatility timing strategy and that, among the dynamic strategies, the LMOF model consistently produces forecasts of the covariance matrix that are economically more useful than those produced by the other multivariate conditional volatility models, both short memory and long memory. Moreover, we show that combining long memory volatility with the factor structure yields better results than employing either long memory volatility or the factor structure alone. The factor structure also significantly reduces transaction costs, thus increasing the feasibility of dynamic volatility timing strategies in practice. Our results are robust to estimation error in expected returns, the choice of risk aversion coefficient, the estimation window length and sub-period analysis.     

Poverty among ethnic minorities: the transition process,inequality and economic growth

This article investigates the process of reducing poverty in ethnic minority households. Using two recent Vietnam household surveys, we find that ethnic minority households are more likely to be persistently poor and less likely to be persistently non-poor than ethnic majority households. The within-group component generated by the variation in income within each ethnicity group explains more than 90% of the change in total inequality. Income redistribution plays an important role in decreasing the poverty gap and decreasing poverty severity. Different ethnic groups have different poverty patterns, which should be noted when designing policies to alleviate poverty and inequality.     

Are children an incentive or a disincentive for migration? Evidence from Vietnam

This study analyzes the influence of children on household migration decisions using data on current internal movement in Vietnam a country that has experienced significant rural–urban migration in the recent years. Families with children usually have three migration choices: move together, stay together or send only one parent to work afar. Using an instrumental variable approach, we show that having an additional child reduces the probability of household migration by 0.0115, while it increases the likelihood of fathers’ migration by 0.0121. These effects suggest that households with more children may be less mobile but may have a greater economic need for migration.     

Australia's Immigration Selection System and Labour Market Outcomes in a Family Context: Evidence from Administrative Data

This paper examines the efficacy of the Australian points system in a family context among working-age permanent resident immigrants who arrived between 2000 and 2011 when there was a major focus on skills selection. Sixty-seven per cent of these immigrants were granted a skilled visa while 25 per cent hold a spousal visa (spouses of Australian citizens). More than half of the skilled visa recipients are the spouses of the primary applicants. Primary applicants among skilled visa holders are assessed for their skills in line with the Australian points system but secondary applicants, such as spouses, among skilled visa holders and spousal visa holders are not subject to any skills assessment before becoming permanent residents. We study differences in economic outcomes by permanent visa types and the role of points system factors in explaining these differences using the Personal Income Tax and Migrants Integrated Dataset and the Australian Census Longitudinal Dataset. We find that primary skilled visa holders earn at least 26–28 per cent more than spousal visa holders, and this is similar for both genders. However, spouses of primary skilled visa holders earn 13–18 per cent more than spousal visa holders. This difference is higher among females than males. Occupation differences can account for nearly half of the differences in income and can entirely capture the role of education and English proficiency. Primary skilled immigrants and their spouses have higher rates of labour force participation and employment than spousal visa holders, starting in the first year of arrival, and the gap is much higher for primary skilled visa holders, but these differences do not disappear quickly.     

Social capital and human resource management in international joint ventures in Vietnam: a perspective from a transitional economy

This study highlights the importance of social capital in international joint ventures (IJVs), and examines human resource practices as a factor shaping such social capital. Comprehensive measures of social capital are developed and tested, which extend prior work on ‘bonding’ and ‘bridging’ social capital. We also link social capital with its anticipated antecedents and consequences. The study's findings are based on data collected from 164 IJVs located in Vietnam. IJV performance was predicted by training and by the level of trust and cooperation between foreign and local personnel. Training (including acquisition of management skills, technology, and cross-cultural understanding) also was predictive of the measures of social capital. A key practical implication arising from this study is that the return on investment from training of joint venture personnel can stem not only from the transfer of technical and management skills needed for developing competitive advantage, but also from the positive impact on social capital, which further contributes to venture success. The establishment of written objectives and plans for the venture, as well as the IJV's level of control regarding its own HR functions also was found to be related to some components of social capital. The findings of this study reinforce the call to build on the contributions of local personnel in joint ventures, and in Vietnam in particular.     

Inter-Temporal Decompositions of Labour Market and Social Outcomes

This paper compares the Wellington (1993) and Smith and Welch (1989) decompositions of changes in labour market outcomes over time. The two examples considered are differences by gender in educational attainment and the gender wage differential. The results suggest that even though the procedure developed by Wellington (1993) has been favoured in recent research, the Smith and Welch decomposition is a more informative approach.     

High School Graduation in Australia: Do Schools Matter?

This study examines the determinants of high school graduation in Australia. It uses two main approaches to estimation. The first of these is a conventional probit model based on a range of family background and demographic variables. This approach is then extended through consideration of a random parameters probit model. The results show that schools matter to the chances of completing high school in Australia. However, the school effects seem to have more to do with the selection of more able students with superior socioeconomic backgrounds than with the independent creation of favourable school or classroom climates.     

The ex-date impact of special dividend announcements: A note

This study examines the impact of special dividend announcements for a sample of Australian companies on the ex date of the special dividend. This study documents that the drop-off ratio is significantly greater for special dividends that participate in DRPs than non-DRPs. Further, it reveals that the drop-off ratio is greater for resources firms than for financial and industrial firms. Finally, a cross-sectional regression model reveals that the drop in price on the ex-date is significantly related to the announcement period price reaction, DRPs versus non-DRPs, size of the company, and special dividend per share.
