Too Good to be True? An Analysis of the Options Market's Reactions to Earnings Releases

Using option implied risk neutral return distributions before and after earnings announcements, we study the option market's reaction to extreme events over earnings announcements. While earnings announcements generally reduce short‐term uncertainty about the stock price, very good news does not reduce uncertainty and slightly bad news actually increases uncertainty. We also find that left tail probabilities decrease over earnings releases while right tail probabilities increase. We interpret these findings as evidence of maintained investor expectations that very good news is generally not released during earnings announcements, combined with skepticism in the form of lingering uncertainty at the release of such very good news.     

Comments on the Institutionalist View of Reaganomics

Gender inequality is caused by numerous factors, among which one may find traditional division of labor, family, religion and many other institutions. The state also influences a position of women in society and economy. Nowadays most western states seem to engage in the promotion of equal status of men and women. The European Union (EU) is known for its policy of gender mainstreaming that has been implemented in member states. The EU, however, promotes a neoliberal approach in the economy that seems to be in contradiction to the promotion of gender equality.

In Poland, tendencies to liberate, privatize and deregulate are warmly welcomed as cures for economic underdevelopment. Gender equality, on the other hand, has been challenged as a relic of the former political system. In this paper, the author attempts to answer the question whether macroeconomic policy promoted by the EU influences the status of women in Poland.     

Staged investments in entrepreneurial financing

Venture capitalists deliver investments to entrepreneurs in stages. This paper shows staged financing is efficient. Staging lets investors abandon ventures with low early returns, and thus sorts good projects from bad. The primary implication from staging is that it is efficient to invest more in later rounds. The model yields a number of predictions on how the ratio of early to late round financing varies with uncertainty, the outside options of both parties, the value of the venture, the costs of investment, and project difficulty. We test these predictions against data on venture capital financings and find significant empirical support for the theory.     

Are some Indian banks too large? An examination of size efficiency in Indian banking

In this paper we use data from the years 1997–2003 to evaluate the size efficiency, as distinct from scale efficiency, of Indian banks. Following Maindiratta [Maindiratta A (1990) J Econ 46:39–56] we consider a bank to be “too large” if breaking it up into a number of smaller units would result in a larger output bundle than what could be produced from the same input by a single bank. When this is the case, the bank is not size efficient. Our analysis shows that many of the banks are, indeed, too large in various years. We also find that often a bank is operating in the region of diminishing returns to scale but is not a candidate for break up.

Injury count model for quantification of risk of occupational injury

Reduction of risk of occupational injuries is one of the most challenging problems faced by industry. Assessing and comparing risks involved in different jobs is one of the important steps towards reducing injury risk. In this study, a comprehensive scheme is given for assessing and comparing injury risks with the development of injury count model, injury risk model and derived statistics. The hazards present in a work system and the nature of the job carried out by workers are perceived as important drivers of injury potential of a work system. A loglinear model is used to quantify injury counts and the event-tree approach with joint, marginal and conditional probabilities is used to quantify injury risk. A case study was carried out in an underground coal mine. Finally a number of indices are proposed for the case study mine to capture risk of injury in different jobs. The findings of this study will help in designing injury intervention strategies for the mine studied. The job-wise risk profiles will be used to prioritise the jobs for redesign. The absolute indices can be applied for benchmarking job-wise risks and the relative indices can be used for comparing job-wise risks across work systems.     

The new-breed approach to 21st century human resources

When the CEO for one of the country's large telecommunications companies selected Bonnie C. Hathcock as chief human resources officer almost six years ago, she had not spent day one in a personnel or human resources assignment. At that time, her career spanned 15 years and included a decade in sales and marketing with a Fortune 50 corporation and two training and development assignments with large multinationals. Now after 20 years of corporate life, Bonnie says, “I love this dynamic profession and have discovered my perfect fit in corporate America.” Bonnie and her team of human resource professionals at Siemens Rolm Communications Inc. in California's Silicon Valley, have launched a progressive human resource strategy and a creative organizational design. In this article, Bonnie shares her approach to 21st century human resources that is newbreed, strategic, and refreshingly unconventional. © 1996 by John Wiley & Sons, Inc.
