Abstract: This paper investigates the capital investment decisions of Korean firms and their impact on shareholder wealth. Overall, we find positive abnormal returns surrounding the announcements of 697 cases of investment projects during the period 1992–1999. This paper also finds that the investment decisions of business group ( chaebol ‐affiliated) firms do not increase shareholder wealth, while the capital investment decisions of non‐ chaebol firms generate significantly positive abnormal returns. The multivariate tests provide consistent evidence that the announcement effects for chaebol firms are lower than for non‐ chaebol firms, after growth opportunities, investment size and firm size are controlled for. The findings support the view that the organizational structure of Korean chaebols creates an incentive for managers to make non‐value maximizing capital investment decisions. 相似文献

清中期广西的客民及土客械斗 总被引:4,自引:0,他引:4
朴基水 《中国社会经济史研究》2005,73(4):59-74
清中期,由于广东与广西之间的不平等商品交换和广东人口大量地向广西迁移,引起了广西社会矛盾的深化。虽然广东的移民(客民)为广西经济的开发作出了贡献,但人口增加与耕地不足的矛盾出现了,其表现形式之一就是客民与土著(包括少数民族)间的械斗。由于恶劣的社会经济条件,造成了大部分客民与天地会、‘海贼’结为一伙,进行了反地方官、反清的活动。自雍正年间开始,广东嘉应州的部分客家不断移居广西东南地区,与土著之间在土地、水利、风水、女人等问题上产生纠纷,导致客民和土著间的械斗。这是广西社会秩序动乱的最基本的因素,也是太平天国运动发展的重要转机。 相似文献

We develop a framework to assess the statistical significance of expected default frequency calculated by credit risk models. This framework is then used to analyse the quality of two commercially available models that have become popular among practitioners: KMV Credit Monitor and RiskCalc from Moody's.
Using a unique database of expected default probability from both vendors, we study both the consistency of the prediction and its timeliness. We introduce the concept of cumulative accuracy profile (CAP) that allows to see in one curve the percentage of defaulting companies captured by the models one year in advance. We also use the Miller's information test to see if the models add information to the S&P rating.
The result of the analysis indicates that these models indeed add relevant information not accounted for by rating alone. Moreover, with respect to rating agencies, the models predict defaults more than ten months in advance on average.

This study examines the effect of multiknowledge individuals (especially those possessing both marketing and technological knowledge) on performance in cross‐functional new product development teams. A survey of 62 cross‐functional teams shows that the proportion of multiknowledge individuals has an indirect positive effect through information sharing on product innovativeness and a direct positive effect on time efficiency of new product development teams. 相似文献

This paper examines the negative market impact that resulted from the insurance regulators’ potential reclassification of 140 hybrid capital securities in spring and summer 2006. It illustrates how financial contagion can spring from a regulatory policy change that lacks transparency. We investigate the impact of the uncertainty surrounding the regulators’ true classification criteria by measuring the effect of the reclassification announcements on hybrid new issue volume, cumulative average abnormal returns, bid‐ask spreads, and yield spreads. The financial contagion adversely affected the entire hybrid capital securities market for six months. The effect was most pronounced among those hybrids that were eventually reclassified as common equity equivalents. It was greater for Yankee Tier 1 hybrids, which had been more popular with insurance firm investors prior to the reclassifications, than among non‐Tier 1 hybrids. 相似文献

The purpose of this study is to explore the effectiveness of 3D simulation technology for enhancing spatial visualization
skills in apparel design education and further to suggest an innovative teaching approach using the technology. Apparel design
majors in an introductory patternmaking course, at a large Midwestern University in the United States, participated in this
study. Three different teaching methods (lecture, 3D simulation instruments, and paper patternmaking) were employed in consecutive
instructional phases, within a single day. A short questionnaire devised to assess students’ visualization abilities and overall
evaluation on the three different teaching methods was administered to the students after each of the three phases. Overall,
students’ abilities to visualize 2D patterns onto a human body were improved by all three teaching methods. The 3D simulation
instruments anchored positive effects of training on spatial visualization abilities between lecture and paper patternmaking
practices. The results affirm that 3D simulation technology has positive potential as an efficient instructional tool for
improving students’ visualization skills in apparel design. 相似文献

Understanding the Benefit Sought by Rural Tourists and Accommodation Preferences: A South Korea Case
Duk‐Byeong Park Hee‐Jung Lee Yoo‐Shik Yoon 《International Journal of Tourism Research》2014,16(3):291-302
Rural tourism has been widely acknowledged for its effectiveness in contributing to rural areas’ development. With strong government support, rural tourism has developed in many countries during the last several decades. This study aims to improve the understanding regarding tourism in Korean rural areas using a segmentation approach. The responses of 442 tourists in 23 rural villages were analyzed. Four segments of tourists were identified based on the different benefits they sought for their vacation in rural establishments. The estimation of a multinomial logit model determined the socio‐demographic characteristics and the preferred accommodations of a rural tourist. Discussions and implications of the detailed findings are provided in the last section. Copyright © 2012 John Wiley & Sons, Ltd. 相似文献

abstract We used data from the British 1998 Workplace Employee Relations Survey (WERS98) to examine key unanswered questions about the impact of gender similarity on employee satisfaction at work. The study sample consisted of 11,848 men and 11,278 women from over 1700 workplaces across Britain. In line with gender‐specific compositional arguments, the effects of gender similarity were found to be asymmetrical for men and women, with similarity tending to have a greater positive impact on men than on women. The effects involved were primarily linear in nature. Net of the potentially confounding influence of other factors, they were also found to be quite weak, weaker than has commonly been suggested in the literature. 相似文献
