In this paper we investigate the use of the structured full rank model for hedging the balance sheet of a financial institution. Simulation results suggest that the optimal hedge is insensitive to changes in parameter estimates. In addition, we hedge a portfolio of Treasury bills using both the full information covariance matrix and the structured covariance matrix. We then contrast these results with those obtained from a duration-based model. Empirical results suggest that the structured full rank model is generally more effective in hedging applications than either the full information model or duration-based model.  相似文献

Managerial Equity Ownership and the Demand for Outside Directors   总被引:1,自引:0,他引:1  
This paper examines the linkage between the use of outside directors and managerial ownership. We conjecture there are two linkages: the standard incentive‐alignment demand for monitoring when managers own little stock and an entrenchment‐amelioration demand when managerial stock ownership is high. As a consequence, we predict the association between managerial ownership and board composition will be nonlinear (U‐shaped if the entrenchment effect is sufficiently pronounced). Using UK data, we find that both quadratic and logarithmic models outperform the simple linear relationship assumed in prior research and that the substitution between managerial ownership and board composition is stronger than hitherto supposed.  相似文献

Layered fertility trenches when compared with conventional gardening methods showed little, if any, benefits in yield or water conservation on two soils over several planting seasons. While not conclusively discounting the fertility trench method, it brings into question the wisdom of introducing new methods that may not have clear advantages over traditional methods.  相似文献

This paper examines the comments submitted by UK companies on 20 proposed accounting standards to test the hypotheses that executives favor standards that increase, or dampen the variance of, accounting profit numbers on which their incentive remuneration is based. Test results were generally as hypothesised but only the profit variance outcomes were statistically significant. Allowing for political environment changes affected only the profit variance results. There was no evidence that the relative monetary size of bonus payments was a significant lobbying factor. No significant differences were found between the lobbying preferences of companies with or without executive incentive schemes.  相似文献

I examine the aggregate expected profit generated by informed traders of diverse ability in a competitive market. I assume that efficient traders get perfect information on asset values whereas inefficient traders get noisy information. In the presence of order size restrictions, I show that the aggregate expected profit generated by efficient and inefficient traders together can be higher than that generated by efficient traders alone. Thus, inefficient traders can create value in a constrained trading environment.  相似文献

This study develops a scale, using the American Marketing Association’s code of ethics, to measure the marketing-related norms of marketing practitioners. The scale has five dimensions: 1) price and distribution, 2) information and contracts, 3) product and promotion, 4) obligation and disclosure, and 5) general honesty and integrity. The relative influence of personal moral philosophies and organizational ethical climate on the norms of marketers was also examined in this study. He received his Ph.D. in marketing from Texas Tech University. His work has previously appeared in theJournal of Macromarketing, Journal of Business Ethics, Research in Marketing, Business and Professional Ethics Journal, andJournal of the Academy of Marketing Science, as well as various other journals and proceedings. His research has been accepted for publication in theJournal of Pharmaceutical Marketing and Management and theJournal of Business Ethics, and has been published in various national and regional proceedings. His research interests include marketing ethics, health care marketing, international marketing, and direct marketing. He received his Ph.D. in marketing from the University of Mississippi.

Previous research has developed a representation for the Condorcet efficiency of plurality and negative plurality rules on three candidates for large electorates under the impartial culture condition. This study considers the two stage voting rules on three candidates, plurality elimination and negative plurality elimination. A representation is obtained for the Condorcet efficiency of each for large electorates under impartial culture. The Condorcet efficiencies of both rules are equal and are shown to be substantially greater than the Condorcet efficiency of plurality and negative plurality.  相似文献
