In this study the role of private placements of debt in the capital acquisition decision of public utilities is investigated. Whereas public offerings are sales of securities through financial intermediaries to the public-at-large, private placements are direct sales of securities by an issuing corporation to a limited number of institutional investors. In contrast to the negative stock price reactions typically found for public security sales, private placements are associated with significant positive abnormal returns in the shares of the issuing public utilities. Also, larger private placements appear to elicit a more favorable market response. Results are consistent with reduced information asymmetries and increased monitoring of the issuing firm resulting from the private placement. 相似文献

This paper surveys some recent developments in panel data analysis. In particular, it focuses on the error component model which is popular in panel data applications, and discusses recent advances in its estimation under heteroscedasticity, serial correlation, and a general variance-covariance matrix. It also surveys the extensions of this model to the seemingly unrelated regressions case, and the simultaneous equations case. The dynamic case and the incomplete panel data case are also considered, as well as a host of other miscellaneous extensions. Prediction with this model is briefly surveyed and alternative tests for this model are reviewed. While the bibliography is not exhaustive, this survey should complement previous surveys and should prove useful for researchers working in this area. 相似文献

This paper uses some newly developed methods and techniques to examine the dynamic properties of international output in the presence of a structural break. We provide statistical evidence to show that the unit root test results can, in some cases, be sensitive to whether a one-time structural break in the data is modelled exogenously or endogenously. However, in most cases the unit root test results remain robust to specification of the structural break exogenously or endogenously; moreover, we find that the null hypothesis of a unit root in output can be rejected in favour of a ‘flexible’ trend alternative for a number of countries such as Canada, Denmark, France, and the United States. 相似文献

Studies in marketing often involve application of multi-item scales to measure latent constructs. Once the psychometric properties of a scale have been assessed, responses to individual scale items are often summed to form a composite score, which then is compared across groups by performing statistical tests such as a t test. In this note, we draw researchers?? attention to an often overlooked fact that the t test is attenuated by imperfect measures. As a solution, we propose the disattenuated t statistic and discuss how it would increase accuracy of estimates and affect decisions in the marketing discipline. 相似文献

Preferential trade arrangements should be evaluated by theireffect on prices rather than by their effect on the total valueof trade. This point is emphasized in the theoretical literaturebut rarely implemented empirically. This article analyzes theU.S. Caribbean Basin Initiatives (CBIs) impacton the prices received by eligible apparel exporters. The CBIsapparel preferences are the most important and heavily usedunilateral preferences because of high trade barriers imposedon exports from the rest of the world. A fixed-effects generalizedleast squares (GLS) estimation is used to isolate the effectsof other factors (such as quality, exchange rates, and transactioncosts) and to identify the effects of tariff preferences. CBIexporters capture only about two-thirds of their preferencemargin despite the high degree of competition among importers.This translates into a 9 percent increase in the relative pricesthey receive, with some variance across countries and years.Countries specializing in higher value items capture more ofthe preference margin, and the implementation of the North AmericanFree Trade Agreement (NAFTA) has a negative effect. RemovingMultifibre Arrangement quotas significantly lowers the benefitsof CBI preferences. 相似文献

The chairman of two public companies (and former chair and CEO of Rohm and Haas) draws on his experience as a director of five private and 15 public companies in discussing the challenges and opportunities facing today's corporate boards. Perhaps the most formidable challenge is the pace of technological change, which is making business models ‘in all industries and countries’ obsolete and forcing companies to adapt much more quickly than in the past. Along with the risk of obsolescence is the increase in ‘reputational risk’ associated with an ‘information age’ in which companies are forced to monitor the nearly continuous flow of fact, hearsay, and outright fabrication. The author recommends that public company boards adopt a new ‘partnership’ model. Besides ensuring an ‘ethical tone at the top,’ corporate directors should aim to become partners with the senior management team by playing more active roles in strategic planning, risk management, and the design of performance evaluation and incentive pay systems. In the most striking departure from current practice, the author urges directors to seize the opportunity created by the ‘reconcentration’ of ownership of U.S. public companies by actively engaging large institutional investors in a strategic dialogue about the companies' strengths and vulnerabilities. In so doing, proactive directors can help their management teams preempt shareholder activists and create long‐run value by creating a more effective two‐way channel of communication, one with the potential to give management more confidence when undertaking large strategic investments with longer‐run payoffs. 相似文献

Interval-valued intuitionistic fuzzy sets (IVIFSs) are very flexible tool to cope with the uncertainty arises in multi-criteria decision making (MCDM) problems. In recent times, MCDM problems with interval-valued intuitionistic fuzzy information have achieved more attention from researchers in different areas and consequently, several MCDM methods have been extended for IVIFSs. In this paper, a novel approach based on WASPAS method is developed under IVIFSs. The developed method is based on the operators of IVIFSs, some amendments in the classical WASPAS method and a new process for calculation of criteria and decision experts’ weights. In process for calculating weights, new procedures is propoesd to compute the decision experts’ weights and criteria weights based on interval-valued intuitionistic fuzzy information measures (entropy, divergence and similarity measures) to achieve more realistic weights. Innovative information measures are developed based on the exponential function for IVIFSs to determine the weights of the criteria and decision experts. Since the uncertainty is an unavoidable feature of MCDM problems, the developed method can be a constructive tool for decision-making in an uncertain environment. Further, an uncertain decision making problem of reservoir flood control management policy is implemented with interval-valued intuitionistic fuzzy information, which reveals the effectiveness and reliability of the proposed IVIF-WASPAS method. To validate the result, comparative analysis with existing methods and sensitivity analysis are presented under interval-valued intuitionistic fuzzy environment. 相似文献

The significant negative issuance day returns associated with seasoned equity offerings (SEOs) have been a puzzle. In this paper we provide two explanations for this empirical regularity. First, using an option-based argument, we contend that issuance day returns are negative because of SEO related declines in volatility that reduce the option value of equity. Our empirical examination of US SEOs between 1983 and 2003 strongly supports this contention. Second, we find that the negative issuance date return is also related to market liquidity around the issuance date. Our findings are robust to various sub-samples and the uncertainty resolution argument, and are not driven by SEO buy-sell order imbalances. 相似文献

This study investigates the effects of the exchange rate volatility on the export flows of Indonesia, Malaysia, Republic of Korea, Singapore, Thailand, and the Philippines during 1974–2011. Towards this goal a trade weighted real effective (rather than the bilateral) exchange rate and three different measures of volatility, i.e. obtained from an ARCH model, a GARCH model and a moving-average standard deviation measure are used in this study. Specifically, the export flows between six Asian countries and the rest of the world are investigated rather than focusing on trade with only one country. Our findings reveal that the exchange rate volatility has a significant impact on export flows in the short run as well as in the long run for all the countries in the sample. The impact in the long run is predominantly negative with the exception of Singapore, but in the short run the impact varies across countries. Moreover, our results are robust to the alternative measures of volatility used and most of the findings in the long run and short run are also robust to the crisis period. 相似文献
