In this study we examine the effect of dual trading through unlisted trading privileges (UTPs) on liquidity and stock returns. Stocks with UTPs trade in a different market structure than stocks listed and traded only on the AMEX and NYSE. Differences in market structure may affect stock returns through liquidity services provided by the competing markets. The sample comprises 852 AMEX and NYSE firms that began unlisted trading on the Philadelphia, Pacific, Midwest, or Cincinnati exchanges between 1984 and 1988. The results show significantly positive abnormal returns around the SEC's announcement of a regional exchange's filing for UTPs. The results also suggest that increased competition improves trading liquidity. Only stocks with low liquidity before UTPs announcements experience significantly improved liquidity and positive stock returns.  相似文献

This paper reports an empirical assessment of competitive conditions among the major British banks, during a period of major structural change. Specifically, estimates of the Rosse–Panzar H-statistic are reported for a panel of 12 banks for the period 1980–2004. The sample banks correspond closely to the major British banking groups specified by the British Banking Association. The robustness of the results of the Rosse–Panzar methodology is tested by estimating the ratio of Lerner indices obtained from interest rate setting equations. The results confirm the consensus finding that competition in British banking is most accurately characterised by the theoretical model of monopolistic competition. There is evidence that the intensity of competition in the core market for bank lending remained approximately unchanged throughout the 1980s and 1990s. However, competition appears to have become less intense in the non-core (off-balance sheet) business of British banks.  相似文献

How do firms allocate limited search resources among substituting technologies with uncertain prospects? This paper contrasts three different approaches. The first follows evolutionary theorists' portrayals of decision‐making processes under bounded rationality. The second approach—real option reasoning—fosters flexibility by investing in more than one technology and postponing the decision to specialize. Following the third approach—real option pricing—firms base their search investments on forward‐looking calculations of technology option prices. We lay out the contrasting theoretical assumptions behind each of these three approaches and construct a simulation model to compare their implications.

When you're in the midst of a major career change, telling stories about your professional self can inspire others' belief in your character and in your capacity to take a leap and land on your feet. It also can help you believe in yourself. A narrative thread will give meaning to your career history; it will assure you that, in moving on to something new, you are not discarding everything you've worked so hard to accomplish. Unfortunately, the authors explain in this article, most of us fail to use the power of storytelling in pursuit of our professional goals, or we do it badly. Tales of transition are especially challenging. Not knowing how to reconcile the built-in discontinuities in our work lives, we often relay just the facts. We present ourselves as safe--and dull and unremarkable. That's not a necessary compromise. A transition story has inherent dramatic appeal. The protagonist is you, of course, and what's at stake is your career. Perhaps you've come to an event or insight that represents a point of no return. It's this kind of break with the past that will force you to discover and reveal who you really are. Discontinuity and tension are part of the experience. If these elements are missing from your career story, the tale will fall flat. With all these twists and turns, how do you demonstrate stability and earn listeners' trust? By emphasizing continuity and causality--in other words, by showing that your past is related to the present and, from that trajectory, conveying that a solid future is in sight. If you can make your story of transition cohere, you will have gone far in convincing the listener--and reassuring yourself--that the change makes sense for you and is likely to bring success.  相似文献

On 29th January, 2001, President Bush issued an executive order creating a faith‐based initiative office. This paper examines the history of the separation of church and state in the United States starting with the Constitution's First Amendment which established the freedom of religion. Pertinent historical facts through the 1990s are presented. The paper then defines President Bush's faith‐based initiative and how it will be implemented. There is concern about whether this initiative will violate the Constitutional separation of religion and government. Another concern is how it will affect the religious organisations and the charities it is supposed to be helping. There is also a discussion on whether President Bush's faith‐based initiative will have a positive or negative impact on religious organisations as well as keeping then separate from the government. The concern is whether the initiative will benefit and progress society as a whole. Copyright © 2003 Henry Stewart Publications  相似文献
