Universities and colleges continue to face constraints related to classroom space and faculty time, thus increasing the need to consider options such as hybrid courses that can leverage available resources. This article discusses the benefits of a hybrid course, as well as its design and implementation at a large, public university. In addition, for universities that use the introduction to risk and insurance course as a significant course for attracting majors, we identify the benefits for students from the use of hybrid courses, such as the variety of materials and activities utilized, as well as the flexibility in scheduling. This information may be useful in marketing the course so that it will be immediately attractive to students.  相似文献

Financial planners often advise their clients to first take advantage of employer‐sponsored 401(k) plans, especially those with matching employer contributions. They often recommend next that clients consider a traditional or Roth IRA, depending on their current eligibility and tax bracket. Generally, the traditional IRA tends to be preferable to the Roth IRA if one expects to be in a lower tax bracket during the retirement versus the contribution years. This preference could be impacted by the theoretical or the practical assumptions one could make as to the tax bracket effect, minimum distribution requirements, and the impact of withdrawals on the amount of Social Security benefits taxed. This research compares the traditional and the Roth IRA, examining both the theoretical and practical assumptions of client behavior. The results indicate that the best choice between the types of IRAs depends on whether the investor's actual behavior is consistent with theory or practice.  相似文献

Previous research has examined the demand for life insurance policy loans using aggregate policy loan data. In contrast, we use a detailed household survey data set containing life insurance and policy loan information to alternatively, and in some cases more directly, examine the four hypotheses traditionally associated with policy loan demand. Our research provides the first U.S. evidence (in the post–World War II period) in support of the policy loan emergency fund hypothesis. In particular, we find that the more detailed emergency fund proxies used here reveal a significantly positive relation between loan demand and recent expense or income shocks.  相似文献

We identify finance professors’ opinions on the efficiency of the stock markets in the United States and assess whether their views on efficiency influence their investing behavior. Employing a survey distributed to over 4,000 professors, we obtain four main results. First, most professors believe the market is weak to semi-strong efficient. Second, twice as many professors passively invest than actively invest. Third, our respondents’ perceptions regarding market efficiency are almost entirely unrelated to their trading behavior. Fourth, the investment objectives of professors are, instead, largely driven by the same behavioral factor as for amateur investors–one's confidence in his own abilities to beat the market, independent of his opinion of market efficiency.  相似文献

The operating agreements of many business ventures include clauses to facilitate the exit of joint owners. In so‐called Texas Shootouts, one owner names a single buy‐sell price and the other owner is compelled to either buy or sell shares at that named price. Despite their prevalence in real‐world contracts, Texas Shootouts are rarely triggered. In our theoretical framework, sole ownership is more efficient than joint ownership. Negotiations are frustrated, however, by the presence of asymmetric information. In equilibrium, owners eschew buy‐sell offers in favor of simple offers to buy or to sell shares and bargaining failures arise. Experimental data support these findings.  相似文献

Developing theory from strategic management research in China   总被引:1,自引:9,他引:1  
What are the main approaches to theory development based on strategic management research in China? What are some of the recent efforts in developing theory in this area? What is our recommended approach? To address these questions, this article outlines the three approaches to theory development in China research, articulates the Chinese context within the global economy, and highlights two streams of recent work as examples of following the recommended, integrative approach to theory development.  相似文献

Much research has recognized that cross-disciplinary knowledge inputs are necessary to successful product innovation, particularly in complex products and systems (CoPS) development. This paper focuses on developing an exploratory framework for studying how an inter-organizational knowledge management (KM) approach affects the development of CoPS, and exploring how inter-organizational collaboration affects KM within a CoPS context. Based on a review of the literature and in-depth case studies, this paper puts forward some propositions and develops an integrated conceptual model showing the link between the dimensions of inter-organizational KM and the performance of CoPS development. Finally, the implications of the proposed model for inter-organizational KM in a CoPS environment are discussed.  相似文献

We contribute to the literature on firms' responses to institutional pressures and environmental information disclosure. We hypothesize that CEO characteristics such as education and tenure will influence firms' likelihood to voluntarily disclose environmental information. We test our hypotheses by examining firms' responses to the Carbon Disclosure Project (CDP) and find that firms led by newly appointed CEOs and CEOs with MBA degrees are more likely to respond to the CDP, while those led by lawyers are less likely to respond. Our results have implications for research on strategic responses to institutional pressures and corporate environmental performance. Copyright © 2013 John Wiley & Sons, Ltd.  相似文献

This study examines and extends the resource dependence logic of diversification for a better understanding of outward foreign direct investment (OFDI) activities by emerging market firms. We contend that the diversification logic is bounded by state ownership, an important but less considered component of interdependence. Our empirical results, based on panel data analysis of Chinese listed firms, suggest that the level of interdependence between Chinese and foreign firms in China in multiple forms, including symbiotic, competitive, and partner interdependencies, is positively associated with the level of the Chinese firms' OFDI activities. However, Chinese firms with higher levels of state ownership are less susceptible to the pressures imposed by foreign firms to invest abroad. Copyright © 2013 John Wiley & Sons, Ltd.  相似文献
