We suggest that the medium-term note market provides an excellent laboratory for exploring the relationships between yield, liquidity, and the label affixed to a financial instrument. Crabbe and Turner (1995) examined the liquidity issue and uncovered the counter-intuitive result that issue size is unrelated to liquidity. Their study failed to examine a potential channel for a liquidity effect, however, in the form of multiple issues from a single, typically large, MTN registration filing. We find evidence that file size is significantly related to yield in a number of instances. Several other proxies for liquidity, such as frequency of issue, are also sometimes significantly related to yields. Contrary to Crabbe and Turner (1995) , we find that labeling a security an MTN can have an impact on its yield. The label "note" also appears to matter for yield in some instances. 相似文献

Common sense tells us that the future is an essential element in any strategy. In addition, there is a good deal of literature on scenario planning, which is an important tool in considering the future in terms of strategy. However, in many organizations there is serious resistance to the development of scenarios, and they are not broadly implemented by companies. But even organizations that do not rely heavily on the development of scenarios do, in fact, construct visions to guide their strategies. But it might be asked, what happens when this vision is not consistent with the future? To address this problem, the present article proposes a method for checking the content and consistency of an organization's vision of the future, no matter how it was conceived. The proposed method is grounded on theoretical concepts from the field of future studies, which are described in this article. This study was motivated by the search for developing new ways of improving and using scenario techniques as a method for making strategic decisions. The method was then tested on a company in the field of information technology in order to check its operational feasibility. The test showed that the proposed method is, in fact, operationally feasible and was capable of analyzing the vision of the company being studied, indicating both its shortcomings and points of inconsistency. 相似文献

This paper examines the long-run relationship between short-term and long-term interest rates (both nominal and real) in 19
countries, and explores the possibility that the relationship is statistically stable using Lc, MeanF, and SupF statistics
suggested by Hansen [1992]. Empirical results obtained from various cointegration techniques (Johansen, Phillips and Hansen,
Stock and Watson, and Park) and quarterly data (1973–1998) show considerable support for the expectations hypothesis in all
countries (except the United Kingdom). In a majority of cases, it is also found that a stable relationship exists between
the short-term and long-term interest rates. 相似文献

Endogenous Group Formation 总被引:1,自引:0,他引:1
While the rules governing the formation of groups engaging in collective action may have significant impact on group size and behavior of members, most experiments on public goods have been conducted with the subjects in exogenously fixed groups or of fixed sizes. We study endogenous formation of groups in a public‐goods provision game by allowing subjects to change groups under three sets of rules: free entry/exit, restricted entry with free exit, and free entry with restricted exit. We find that the rules governing entry and exit do have a significant impact on individual behavior and group‐level outcomes. 相似文献

Nonprofit organizations are held to high ethical standards due to their charitable missions serving the common good. Incidents of fiscal mismanagement within the nonprofit sector make it relevant to assay the ethical principles of employees. This study examines the level of Machiavellian propensities of US nonprofit employees. Results indicate Machiavellian propensities do exist in certain nonprofit employees and these employees agree with questionable behavior. Policy makers and oversight agencies may find these results useful in developing corporate governance and accountability measures for nonprofit organizations. Furthermore, board of director members may use these results to monitor employee actions and address management training. 相似文献

In horticultural markets, trade barriers often apply to the processed products whereas domestic support applies to farm-produced raw commodities. Here we assess the effects of such trade barriers and domestic support by simulating the effects of policy reform on global processing tomato markets, which are faced with modest processed product tariffs and high domestic support in the European Union (EU). Both protection and EU subsidy drive down world welfare, but we find that reducing import tariffs for tomato products would yield greater effects on markets and larger welfare impacts outside Europe than would reductions in EU domestic support. 相似文献

We analyze the potential competitive effects of the proposed Basel II capital regulations on US bank credit card lending. We find that bank issuers operating under Basel II will face higher regulatory capital minimums than Basel I banks, with differences due to the way the two regulations treat reserves and gain-on-sale of securitized assets. During periods of normal economic conditions, this is not likely to have a competitive effect; however, during periods of substantial stress in credit card portfolios, Basel II banks could face a significant competitive disadvantage relative to Basel I banks and nonbank issuers. 相似文献

The paper presents a technique developed by the authors, which makes it possible to determine the necessary amount of financing for education at all the budget system levels for 2008-2010, based on the Russian average value of financing, taking into account the budget expenditures index for two variants of student population, i.e. the actual number of on-budget students and the number of students required to meet the economy’s need for trained workers. The technique was developed and the calculations were made on the basis of Russian long-term forecasts and the Russian three-year federal budget for 2008–2010. 相似文献
