Among the various external information sources that influence individual investors' trading decisions, no research has considered the important influence of insiders' transactions. Retail investors might copy the behavior demonstrated by insiders' trading; therefore, this study establishes an approach to estimate the buying probability for a certain stock by a certain investor at a certain point in time and analyzes whether insider trade reports influence this probability. Using a sample of more than 270,000 retail trades in Germany between 2008 and 2009, along with more than 3000 insider trades in the same period, we find evidence of copying of insiders' trades by retail investors. The basic mimicry hypothesis holds, even when we consider an information event hypothesis and an insider attention effect hypothesis as alternative explanations. A robustness test also supports the findings. 相似文献

In this paper, the authors argue that stock options are a highly effective marketing communications (marcoms) medium, which due to their influence on the profitability of the organisation, possess characteristics that should be included in strategic marketing planning for financial and non-financial organisations. This study aims to test whether stock options can be used as a means for marketing strategists to build effective branding and loyalty programmes.It is argued that the strategic role of stock options in marketing decision making adds value in business markets. Stock options play a unique role in marketing and in the achievement of corporate goals and targets. The study is supported by the findings of a questionnaire survey based on a sample of Greek companies, grouped into two categories. The first category consists of the most profitable organisations supplying business markets, listed on the Athens Stock Exchange (ASE) and the second consists of large financial organisations. 相似文献

This study provides evidence that the outcome for shareholders resulting from asset sales is determined at the time of transaction by the value for the asset sold. Assets sold above market value are followed by positive and significant abnormal returns over the following three months; these returns are magnified in firms where the balance of power in corporate governance favors shareholders. Abnormal returns following undervalued asset sales are insignificant from zero, indicating value-preservation. Value-preservation when the assets are sold below market value becomes less likely as firms approach financial constraints. The reverse is true when assets are sold above market value. This evidence is documented for apartment REITs, which have a large number of comparable transactions available for estimating expected market values. 相似文献

Allocating resources to competing large‐scale infrastructure projects involves multiple objectives. Traditional decision‐aiding methodologies focus on the trade‐offs among performance and resource objectives. Existing methodologies may fail to account for unknown and emergent risks that are typical of large‐scale infrastructure investment allocation problems. In modern portfolio theory, it is well known that a diversified portfolio can be very effective to reduce non‐systematic risks. The approach of diversification is equally important in choosing robust portfolios of infrastructure projects that may be subject to emergent and unknown risks. In this paper, we demonstrate a methodology to analyze and compare the diversification of portfolios of large‐scale infrastructure projects. We classify and explore several metrics of diversification and integrate them with risk and other performance objectives in a multiobjective approach. We test the new metrics and the methodology in a case study of hundreds of millions of dollars of infrastructure investments. The results suggest that the solutions that consider diversification are more robust to emergent risks, thus, identifying an opportunity to incorporate diversification‐based optimization methodologies to support a variety of problems involving large‐scale infrastructure investments. 相似文献

To attract students to the risk management and insurance profession, strategies need to be developed to overcome biases in their perceptions of the profession. This study attempts to determine some of those perceptions of students—specifically a group of business career high school students and a group of college students enrolled in an introduction to business course—about the personality traits of insurance professionals. A Personality Factor Questionnaire previously used extensively in other research was used to measure differences in student perceptions of personality profiles of different professions. We also measured how student characteristics such as age, sex, and expected college major influence student perceptions of these traits. The overall general conclusion was that perceptions of the profession are not as negative as many imagine, but do require some substantive work to improve, even among students seeking business careers. 相似文献

Real estate swaps are a recent financial innovation based upon the principle of comparative advantage. A real estate swap is a useful tool for real estate risk management and for participating in real estate investment without the high costs associated with real estate. Potential economic benefits and costs associated with real estate swaps are considered and real estate swaps are compared to alternative tools for real estate risk management. The expected utility and effectiveness of risk management with a swap in a multiperiod framework are analyzed. The analysis finds that the subject property's return and its risk characteristics (as reflected in its correlation with interest rate and property index returns) delimit the risk management potential of a given swap position. Optimal swap positions are shown for various regions and property types based on historical return series, from the period between 1983 and 1992, and the parameters of the dynamic model developed. 相似文献

We exploit a unique sample to analyze how homophily (affinity for similar others) and social ties affect career outcomes in banking. We test if these factors increase the probability that the appointee to an executive board is an outsider without previous employment at the bank compared to being an insider. Homophily based on age and gender increase the chances of the outsider appointments. Similar educational backgrounds, in contrast, reduce the chance that the appointee is an outsider. Greater social ties also increase the probability of an outside appointment. Results from a duration model show that larger age differences shorten tenure significantly, whereas gender similarities barely affect tenure. Differences in educational backgrounds affect tenure differently across the banking sectors. Maintaining more contacts to the executive board reduces tenure. We also find weak evidence that social ties are associated with reduced profitability, consistent with cronyism in banking. 相似文献

This paper investigates the potential of models of the range of equilibria to yield a pattern of equilibrium rates of unemployment that is consistent with the observed mix of cycle with no trend in the rate of unemployment. To do this the paper considers a model in which wages are determined by a group of unionised insiders bargaining with an employer. In the model the supply of labour is endogenous. Specifications of the utility function are found which are consistent with the mix of cycle and no trend in the rate of unemployment. Of these it is concluded that loss aversion in the evaluation of wage relativities is a crucial ingredient for models of the range of equilibria. 相似文献

Personal managerial indiscretions are separate from a firm's business activities but provide information about the manager's integrity. Consequently, they could affect counterparties’ trust in the firm and the firm's value and operations. We find that companies of accused executives experience significant wealth deterioration, reduced operating margins, and lost business partners. Indiscretions are also associated with an increased probability of unrelated shareholder-initiated lawsuits, Department of Justice and Securities and Exchange Commission investigations, and managed earnings. Further, chief executive officers and boards face labor market consequences, including forced turnover, pay cuts, and lower shareholder votes at re-election. Indiscretions occur more often at poorly governed firms where disciplinary turnover is less likely. 相似文献
