Experimental research on Group Decision Support Systems (GDSS) has generally focused on democratic groups whose members typically share the same objectives. In organizations, however, there are many situations where groups have a leader who has the power to override the group's recommendation, the objective of the leader may not be the same as the objective of each member, and not everyone may have the same information. This paper reports the results of an experiment in which the groups, having a designated leader, worked on a mixed-motive task. Within this context, we analyze group decision outcomes and processes for groups that use a face-to-face channel of cormnunication and those that utilize computer mediated communication. We compare performance of the leader and members with respect to an objective measure of performance, the efficient frontier. The results indicate that for this task groups using face-to-face channel outperform groups using computer mediated communication.  相似文献

We investigate whether the merger announcement dates provided in a popular mergers and acquisitions (M&A) database, SDC, serve as accurate event dates for estimating the wealth effects of mergers on target firms located in Turkey. We find that 74 percent of SDC’s merger announcement dates are preceded by merger-related events such as merger rumors, target firms’ search for potential acquirers, and early-stage merger negotiation announcements. Target cumulative abnormal return (CAR) estimates around these early dates are almost twice as large as the CAR estimates around SDC’s merger announcement dates. We argue that our findings have implications for the recently flourishing cross-border M&A literature.  相似文献

Using 28,785 observations of 813 banking institutions in 38 countries during the 1993–2004 period, this study investigates among others, the role of transparency, accounting standards, legal, financing, corporate, and banking environments at the country level and size, risk, and organization form at the bank-specific level affecting the extent of value relevance. The evidence indicates that at the macro-level, the extent of mandated accounting disclosure, differences in accounting measurement practices, and type of legal environment, were the most influencing factors affecting the extent of value relevance of earnings and book values. At the bank-level, the organizational form and risk had the most impact.  相似文献

We investigate how borrowers’ corporate governance influences bank loan contracting terms in emerging markets and how this relation varies across countries with different country‐level governance. We find that borrowers with stronger corporate governance obtain favorable contracting terms with respect to loan amount, maturity, collateral requirements, and spread. Firm‐level and country‐level corporate governance are substitutes in writing and enforcing financial contracts. We also find that the distinctiveness of borrowers’ characteristics affect the relation between firm‐level corporate governance and loan contracting terms. Our findings are robust, irrespective of types of regression methods and specifications.  相似文献

We investigate the role of corporate boards in bank loan contracting. We find that when corporate boards are more independent, both price and nonprice loan terms (e.g., interest rates, collateral, covenants, and performance‐pricing provisions) are more favorable, and syndicated loans comprise more lenders. In addition, board size, audit committee structure, and other board characteristics influence bank loan prices. However, they do not consistently affect all nonprice loan terms except for audit committee independence. Our study provides strong evidence that banks recognize the benefits of board monitoring in mitigating information risk ex ante and controlling agency risk ex post, and they reward higher quality boards with more favorable loan contract terms.  相似文献

This study evaluates how innovation within companies alleviates the information asymmetry problems in relationship lending. We hypothesize that patenting activities could reveal favorable private information and, hence, reduce the information asymmetry between innovative borrowers and banks. Using a sample of US patenting firms from 1987 to 2004, we show that borrowers with higher innovation capability (revealed by having more patent applications, higher research & development (R&D) productivity, or higher‐quality patents) enjoy lower bank‐loan spreads and better nonprice‐related loan terms. Our evidence further suggests that the information benefits of patenting activities on loan spreads is more pronounced for small or less R&D‐intensive firms.  相似文献

This paper investigates the predictability of the volatilities of large versus small firms. Using AR-GARCH models we show that there is symmetry in the ability of firms of different market values to predict conditional variances. Specifically, we show that volatility surprises of small (large) firms are important in predicting the conditional variance of large (small) firms. These results are different than those previously reported which indicate that there is an asymmetry in the predictability of the volatilities of large versus small firms. This predictive ability is still present when the equation of conditional variance includes state variables such as the default premium, dividend yield and the term premium. Finally, our results indicate that the pattern of symmetric predictability is present in both pre- and post-war sample periods.  相似文献

In this paper we consider some factors which are of potential importance in the debate concerning the sources of performance for intermediaries. Using data from depository institutions (banks and savings and loans), we find that the distributional intensity (provided by standardized number of offices in a market) is consistently important in explaining cross- sectional profitability. This result implies that the number of offices in a market is at least as important as more traditional measures of efficiency and concentration in determining returns in this sector of the financial services industry. Indeed, when pooled data are used, there is a strong quadratic relationship between return on assets and the number of offices in a market. We show that this relationship can be viewed as coming from spatially differentiated markets as opposed to collusion or efficiency per se. Finally, we provide evidence that results concerning the rule of efficiency versus market concentration are themselves sensitive to the implicit assumption that there are no close substitutes for the services provided by a sub-set of the industry. In particular, results from ‘pooled’ bank and thrift data often provide conclusions which are different from those which include only banks. © 1997 John Wiley & Sons Ltd.  相似文献

城市化与城市生态环境之间存在着一定的关系.近年来,特别是南疆铁路西延工程全线贯通并投入正式营运以后,铁路对穿越城镇并铁路沿线周边城镇的发展带来了很好的机遇,促进了该区域的经济的发展及城镇化,同时该区域的城镇生态环境也发生了很大的变化.本文在南疆铁路沿线四个城市的2000、2006、2008年统计资料的基础上,首先运用综合评价方法对南疆四城市的城市化水平进行了综合评价,然后分析了南疆四个城市的城市生态环境情况,最后对城镇化与城市生态环境之间的关系进行了分析.结果表明,2000年以来,南疆铁路沿线四城市的城市化水平相对于2000年具有上升趋势.库尔勒市的生态环境水平与城市化水平之间有协调发展特征,但其它三个城市的生态环境水平与城市化水平之间存在不协调发展情况.因此,必须加强阿克苏市、阿图什市、喀什市的城市生态环境的保护工作以促进城市生态环境与城市化水平的协调发展.  相似文献
