流动性、负债融资及代理成本

以中国上市公司为研究对象,考察负债融资及债权人对大股东自利行为与管理者代理行为的影响.从而揭示中国上市公司中债权人抑制大股东和管理者自利行为的动机.利用中国上市公司的数据,实证检验了企业流动性较好时,负债融资对大股东自利行为和管理层代理行为的影响,并揭示了中国上市公司中股东-债权人冲突和负债作为治理机制所带来的经济后果.实证结果表明,当企业流动性较差时,负债融资对大股东自利行为和管理者代理行为有显著抑制作用.当企业流动性较好时,负债融资对大股东自利行为和管理层代理行为无显著抑制作用.

Ethical Attitudes of Accounting Practitioners: Are Rank and Ethical Attitudes Related?

We address a previous finding in the business ethics literature in which accounting professionals in higher rank levels, i.e., “manager” or “partner” of auditing firms, appear to have lower moral reasoning ability than their junior counterparts. Prior investigations have relied upon a similar methodology for estimating ethical beliefs, namely testing “moral reasoning ability” using either the Moral Judgment Interview or Defining Issues Test. In the present study, we use a multiple vignettes approach to test for the existence of the inverse rank-ethical beliefs effect. With only 2 of the 30 vignettes resulting in both managers and partners being more accepting of the ethically charged behaviors, the results presented here using this alternative methodology are generally not supportive of the inverse rank-ethical beliefs phenomenon. We also use a multivariate analysis in order to control for demographic characteristics. Our results suggest that the most robust predictor of ethical attitudes among accounting practitioners is age, not rank within a firm.

Bringing science to market: commercializing from NIH SBIR awards

We offer empirical information on the correlates of commercialization activity for research projects funded through the US National Institutes of Health's (NIH's) Small Business Innovation Research (SBIR) award program. Based on this analysis we suggest possible recommendations for improving this aspect of the performance of NIH's SBIR program. Specifically, we estimate a model of the probability of commercialization as a function of the project's ability to attract additional developmental funding, along with other control variables. We find that additional developmental funding from non-SBIR federal sources and from own internal sources are important predictors of commercialization success, relatively more so than additional developmental funding from venture capitalists. We also find, among other things, that university involvement in the underlying research increases the probability of commercialization. Thus, these factors should be considered by NIH when making awards, if increased commercialization is an objective.     

Determinants of private health insurance coverage among Mexican American men 2010–2013

Abstract

Background: Private health insurance (PHI) represents the largest source of insurance for Americans. Hispanic Americans have one of the lowest rates of PHI coverage. The largest group in the US Hispanic population are Mexican Americans; they account for about two in every three Hispanics. One in every three Mexican Americans aged 64 years and under did not have health insurance coverage. Mexican Americans have the most unfavorable health insurance coverage of any population group in the nation.

Objectives: The objective is to determine the factors associated with the gap in PHI coverage between Mexican American and non-Hispanic American men.

Methods: This study used the National Health Interview Surveys (2010–2013) as the sample. A non-linear Oaxaca-Blinder decomposition was run, estimating the explained and unexplained gap in PHI coverage between the groups. Several robustness tests of the model were also included.

Results: This study estimates that 44.4% of employed Mexican American men are covered by PHI compared to 79.5% of non-Hispanic American men. Nearly 60% of employed Mexican American men were found to be foreign born, 35% have an educational attainment less than a high school degree, and 40% are likely to have language barriers. Decomposition results show that income, low educational attainment, being foreign-born, and language barriers diminished the probability of private health insurance coverage for Mexican Americans, and that 10% of the gap is unexplained.

Conclusions: Most of the difference in the PHI rate between Mexican American men and non-Hispanic men is explained by observable differences in group characteristics: education, language, and immigration status. About 10% of the difference can be attributed to discrimination under the traditional interpretation of an Oaxaca-Blinder decomposition. The PHI rate gap is large and persistent for Mexican American men.     

Financial integration and the ASEAN-5 equity markets

The existence of long-run relationships among the ASEAN-5 equity markets is empirically investigated. This study utilized weekly data spanning January 1988 to August 1999. The results of Granger noncausality test due to Toda and Yamamoto (Journal of Econometrics,66, 225–50, 1995) reveal that the Singapore equity market was not affected by other markets except by the Philippines in the long run. This result shows that there exist opportunities for beneficial international portfolio diversification within the context of the Asean-5 equity markets.     

Engineering and technology students’ perceptions of courses

As cultural, social, political and economic changes take place, the secondary or high school curriculum should reflect and respond to changing needs and aspirations of students. Technology Education has been proactive in this arena as it has transformed over the decades to meet ever-changing societal needs. The most recent change to the discipline has been to add engineering and, as a result, adopting a new name and curriculum-Engineering and Technology Education. The added component and name change in Technology Education is causing discussions about what the new direction means, what professional preparation changes will be incurred, and what work graduating students will be prepared to do. In light of these changes, this study investigated perceptions of high school students in the United States of America about engineering and technology courses they take. To investigate whether students’ perceptions are in accord with current changes in Engineering and Technology Education, 316 students enrolled in engineering and technology courses in Georgia schools that have an affiliation with the Georgia Engineering and Technology Education Association (GETEA) were surveyed. According to data analyses, students’ perceptions can be divided into two factors. Educational Value of Course (factor 1) was extracted from statements measuring the degree to which the courses prepare students for employment and provide them with information regarding future employment. Personal Relevance of Course (factor 2) was derived from statements measuring students’ perceptions about links between engineering and technology education and their personal lives. Such findings suggest these students valued their engineering and technology courses, planned to continue their education, made good grades, and had varied types of career expectations for jobs such as design engineers and architects.
