Opponents of U.S. and Canadian strike replacement legislation contend that restricting the use of strike replacements significantly alters bargaining power and increases strike activity. This article uses data on Canadian manufacturing collective-bargaining agreements to investigate these hypotheses. Although a general ban on strike replacements is found to be associated with longer strikes, little evidence is found to suggest that banning permanent strike replacements significantly influences strike incidence, strike duration, or negotiated wages. 相似文献

The Chicago Board Options Exchange concurrently listed European‐style and American‐style options on the Standard and Poor's 500 Index from April 2, 1986 through June 20, 1986. This unique time period allows for a direct measurement of the early exercise premium in American‐style index options. In this study, using ask quotes, we find average early exercise premiums ranging from 5.04 to 5.90% for calls, and from 7.97 to 10.86% for puts. Additionally, we are able to depict a potentially useful functional form of the early exercise premium. As in previous studies, we find some instances of negative early exercise premiums. However, a trading simulation shows that traders must be able to trade within the bid–ask spread to profit from these apparent arbitrage opportunities. © 2003 Wiley Periodicals, Inc.

In the e-world where many of us live and work, virtual work arrangements will become increasingly commonplace. This paper reports on an exploratory study into the way in which consultants can ply their trade virtually with clients whom they never meet. US-located e-consultants provided advice to Hong Kong-located web site developers on the interface and content aspects of a website that was being developed for an international audience. Extensive analyses of the communication between the consultants and developers is undertaken, in parallel with an analysis of survey data obtained from the two sets of stakeholders. Lessons are drawn for future research and practice. 相似文献

A model to simulate the costs and returns of an individual dairy cow over 14 years under various assumptions of genetic potential, health status and management was developed especially to evaluate the effects of diseases that reduce production and reproduction efficiency and to evaluate alternative management interventions. Data were collected from the Food Animal Health Resource Management System (FAHRMX), Today's Electronic Planning (TELPLAN), Today's Electric Farm Accounting (TELFARM) databases and secondary sources at Michigan State University. A case study of cystic ovaries was analysed using the model. The results showed that it is more economical to treat cystic ovaries than not to treat, and treatment with Gonadotropin Releasing Hormone (GNRH) was superior to Human Chrionic Gonadotropin (HCG). Four to five lactations were the optimum for keeping a dairy cow to replacement and it was estimated that there is a loss of US$0.45 per day of extended calving interval (days open beyond the optimal 70 days). 相似文献

The complex integration strategies of multinationals and cross country dependencies in the structure of foreign direct investment 总被引:13,自引:0,他引:13
The behavior of many multinational enterprises is not well described by existing models of foreign direct investment (FDI). Firms often follow strategies that involve vertical integration in some countries and horizontal integration in others, a strategy known as complex integration. This paper presents a three-country model that is used to analyze why firms might follow a strategy of complex integration. My analysis reveals that complex integration strategies create complementarities between potential host countries that have important implications for the structure of FDI. The analysis also shows that falling transport cost between countries may increase the importance of complex integration strategies. 相似文献

Asian brands have often struggled to develop quality images. The visual aspects of branding have received little attention on how they might be used to strengthen brand perceptions in Asia. Guidelines for designing visual brand stimuli are developed using evaluations of logos in China and Singapore. There is a significant relationship between design and the responses companies seek, including positive affect, perceptions of quality, recognition, consensus in meaning, and feng shui. How designs are perceived, and their effect on consumer responses, were similar between China and Singapore. Companies are encouraged to leverage design to strengthen their brands. In particular, they should select logo designs that are elaborate, natural, and harmonious as these created positive affect and quality perceptions, clear meaning, true recognition, and feng shui. Many of these relationships hold in the United Sates as well, implying that the visual aspects of brand strategies may accomplish companies' goals across international borders. 相似文献

In this paper we re-examine the effect of 12b–1 payments on mutual fund expense ratios by analyzing data from 1988 through 1991. The findings are consistent with previous studies that find charges are a dead-weight cost borne by shareholders. However, we show that this cost increases over time. 相似文献
