Impact of Green Innovation on Labor Productivity and its Determinants: an Analysis of the Korean Manufacturing Industry

Due to worsening environmental conditions around the globe, firms have been investing a great deal of money in green technologies as a way of coping with the environmental crisis. This paper uses a unique data set based on the Korea Innovation Survey to examine the impact of green innovation on labor productivity, and the determinants of environmental activities in 2010. The empirical results show that green innovation intended for both firm and customer benefits has a positive effect on labor productivity. This finding means that firms need to implement firm‐oriented green innovation as well as customer‐oriented green innovation in order to increase their performance. Our findings also show that there are significant differences in aggregate green innovations depending on different firm sizes and industries. Specifically, large firms implement environmental activities more than small ones, and pollution‐intensive industries tend to invest more in activities related to environmental technology.

A Taxonomy of Social Networking Site Users: Social Surveillance and Self‐surveillance Perspective

Since social networking sites (SNS) are widely used in modern society, users increasingly use SNS to manage or maintain their existing social relationships and form new ones. This research applies social surveillance and self‐surveillance to classify SNS user types and explores each type's effect on SNS’ marketing performances. Three hundred three online questionnaires are collected to test the research questions. The results of cluster analysis and multivariate analysis of variance (MANOVA) reveal the following four user types based on the different degrees of social surveillance and self‐surveillance: versatile users, self‐expression users, pass‐along users, and introvert users. Further, the introvert users have the least impact on product‐related information sharing, perception of social presence, purchase intention toward offers on SNS, and emotional experiences in social shopping among the four SNS user types.     

Union relevance in the Malaysian labour market

The study estimates the effect of union membership on workers' wages using individual‐level data from a survey conducted among employees in various sectors in Malaysia in 2012. Initial results show that union membership has a positive effect on wages. However, after controlling for endogeneity, union membership or the presence of a labour union within a firm is not statistically significant for individual wage levels. Because there is no trade union wage premium, the study suggests that the revival of labour union membership is not going to be an easy task.     

Assessing the Effects of Leadership Styles on Employees’ Outcomes in International Luxury Hotels

This study examines the effects of transformational, transactional, and non-transactional leadership on hotel employees’ outcomes including extra effort, perceived efficiency, and satisfaction with managers. Employees from eleven 4-star hotels in Spain provided the collected data. A series of statistical analyses (1) identify the elements of three leadership styles using a multi-factor leadership questionnaire (MLQ-5X); (2) examine the effect of leadership styles on employees’ outcomes. The results of this study indicate that “idealized attributes” of transformational leadership and “contingent reward” from transactional leadership are the most important factors that positively affect all three outcomes (i.e., extra effort, perceived efficiency, and satisfaction); and (3) to assess the moderating effect of different types of ownership of hotel properties on the relationship between styles of leadership and outcomes of employees’ activities other than these two elements, the significant factors indicating positive or negative relationships vary depending on the types of individual outcomes as well as ownership of hotel properties. The discussion sections indicate theoretical and practical implications of the findings.     

The Economic Impact of Wireless Number Portability

This paper examines the price response of wireless carriers to the introduction of number portability in the U.S. I find that wireless prices decreased in response to number portability, but not uniformly across plans. Average prices for the plans with the fewest minutes decreased by only $0.19/month (0.97%), but average prices for medium and high‐volume plans decreased by $3.64/month (4.84%) and $10.29/month (6.81%), respectively. The results suggest that higher‐volume users in the wireless market benefited more from the policy‐induced reduction in switching costs.     

Meeting the Needs of Organic Farmers: Benchmarking Organizational Performance of University Extension

A stochastic frontier model is used to explain the performance evaluation by organic producers of programs provided by the U.S. university extension systemproviders. We identify nonmanagerial factors that influence both performance ratings and performance efficiency, defined as achieving a rating as close to the highest rating as possible. Results based on the organic farmer evaluators indicate that extension agents are performing at high mean efficiency of 0.95, but that the average rating is relatively low at 2.66 on a four-point scale. Years of experience in organic farming and the severity of production problems facing farmers have significant impacts on performance ratings.     

Economic returns to schooling in urban China, 1988 to 2001

This study provides estimates of the returns to schooling in urban China over an extended period of economic reforms. We find a dramatic increase in the returns to education, from only 4.0 percent per year of schooling in 1988 to 10.2 percent in 2001. Most of the rise in the returns to education occurred after 1992 and reflected an increase in the wage premium for higher education. The rise is observed within groups defined by sex, work experience, region, and ownership, and is robust to the inclusion of different control variables. The timing and pattern of changing schooling returns suggest that they were influenced strongly by institutional reforms in the labor market that increased the demand for skilled labor.
