Expropriation and direct investment 总被引:1,自引:0,他引:1
The paper considers a model in which private foreign investors make direct long-lived capital investments in a small developing country that is subject to stochastic shocks to production. Depending upon the preferences of the host country, we find that expropriation can occur because of either 'desperation or ‘opportunism’. We show that under reasonable assumptions increased investment makes expropriation less likely to occur, and that the level of investment chosen by atomistic foreign investors may be non-optimal. 相似文献

Alba and Chattopadhyay (1985, 1986) have demonstrated that having consumers think about a familiar brand can interfere with the retrieval of competitive brand names, including those that might otherwise be considered for purchase. However, their research is silent about two issues of pragmatic importance. First, is it possible to inhibit retrieval of the consumer's preferred brand? Second, can an unfamiliar brand evoke recall inhibition? Our findings indicate that recall inhibition does not extend to the preferred brand. Our findings further suggest that recall inhibition can be induced by cueing consumers with an unfamiliar brand name, but that such inhibition is less pervasive than evoked by a highly familiar brand name. 相似文献

A model of information technology (IT) ethical work climates is presented. Using these ethical work climates and data collected from a national mail survey of Association for Computing Machinery (ACM) members, empirical measures were developed and evaluated. A mailing of 2446 questionnaires was sent to ACM members and 136 usable responses were returned (5.6%). Using these data, an exploratory factor analysis was performed using principle components analysis to identify the IT ethical work climates from the data. Six of these work climates were identified as predicted by the model. Two ethical work climates that were combinations of the proposed climates were also identified.From the results of the exploratory factor analysis, a confirmatory factor analysis was performed using Calis in PC SAS version 8. The purpose of this analysis was to evaluate the overall fit of these measures to the data and evaluate the psychometric properties of the measures. The fit of the IT ethical work climates model was acceptable. The psychometric properties of these measures were good. Based on these results, conclusions, limitations of the study, and directions for future research are proposed. 相似文献

This study examined the relationship between the proportion of women serving on firms' boards of directors and the extent to which these same firms engaged in charitable giving activities. Using a sample of 185 Fortune500 firms for the 1991–1994 time period, the results provide strong support for the notion that firms having a higher proportion of women serving on their boards do engage in charitable giving to a greater extent than firms having a lower proportion of women serving on their boards. Further, the results suggest a link between the percentage of women on boards and firm philanthropy in the areas of community service and the arts, but found no link between women boardmembers and firm giving to support education or public policy issues. The implications of the findings and some areas for future research are discussed. 相似文献

In this editorial to a collection of papers on ethics in small firms, the case is made for greater use of high quality empirical research on business ethics. Sociological perspectives have much to offer to the field of business ethics that continues to be dominated by normative, moral philosophy. The second contribution of the paper is to argue for a re-orientation away from the large multi-national firm as a benchmark subject of business ethics research. One important point of view to be included is that of the small firm, which remains the dominant organisational form throughout all the OECD countries. 相似文献

How quickly do central bank intervention operations impact the foreign exchange market? And, do intra-daily market conditions influence the effectiveness of central bank interventions? This paper uses high-frequency intra-daily data to examine the relationship between the efficacy of intervention operations and the “state of the market” at the moment that the operation is made public. The results indicate that some traders typically know that the Fed is intervening at least 1 h prior to the public release of the information in newswire reports. Also, the evidence suggests that the timing of intervention operations matters—interventions that occur during heavy trading volume, that are closely timed to scheduled macro announcements, and that are coordinated with another central bank are the most likely to have large effects. 相似文献

This study seeks to answer the following question: Can sales representatives enhance their performance through their acceptance of information technology (IT) tools? Using data collected from two companies, we show that despite uncertain results and the frequent resistance among salespeople to IT interventions, IT acceptance indeed has a positive effect on sales performance. This occurs because salespeople using IT expand their knowledge and, in turn, gain improved targeting abilities, enhanced presentation skills, and increased call productivity. Thus, sales representatives have a strong incentive to accept IT because doing so is likely to sharpen their own job performance. 相似文献

In this article, a typology is presented which will help organizations better reflect the brand image they desire. The assisting typology is based on the extent to which employees know and understand the organization's mission, values, and desired brand image, and the degree to which they perceive their psychological contracts with the organization as being honored. Organizations can be classified as all-stars, rookies, injured reserves, or strike-out kings, based on the characteristics of a preponderance of their employees. As categorized, rookie organizations cannot deliver the desired brand image because most of their employees lack the knowledge and understanding to do so. Injured reserve organizations, on the other hand, cannot achieve the same because firm employees perceive their psychological contracts with the organization as having been violated, which renders the individuals unwilling and unmotivated. For their part, strike-out king organizations share rookie and injured reserve organizations' worst characteristics. Finally, and conversely, all-star organizations consistently deliver the desired brand image to others because their employees are both able and motivated to do so. To help firms attain this highly desired status, specific guidelines are presented herein which may help organizations become “all-stars” in their own right. 相似文献

Technology spillover through trade and TFP convergence: 135 years of evidence for the OECD countries 总被引:7,自引:0,他引:7
Jakob B. Madsen 《Journal of International Economics》2007,72(2):464-480
Using a new dataset on imports of technology and total factor productivity (TFP) over 135 years for the OECD countries, this paper tests whether knowledge has been transmitted internationally through the channel of trade. The empirical estimates show that there is a robust relationship between TFP and imports of knowledge and that 93% of the increase in TFP over the past century has been solely due to imports of knowledge. Furthermore, it is shown that knowledge spillovers have been an important contributing factor behind the TFP convergence among the OECD countries over the period 1870 to 2004. 相似文献
