That survey research is error prone is not a new idea and different varieties of non-sampling error have been investigated
in the literature as well as consideration being given in many statistics textbooks to the issue of sampling error. The paper
here considers research upon corporate environmental reporting. It compares information provided by corporate environmental
reports with information that survey respondents claim their organization’s environmental report contains. This enables the
accuracy of the claims to be assessed. Consideration is given to two different industries the Water industry and the Energy
industry. Errors due to inaccurate reporting by survey respondents are shown to be relatively infrequent and respondents appear
just about as likely to claim they report information that they do not, in fact, report as to fail to indicate that they report
information that is, in fact, actually reported. 相似文献

It seems that everybody wants to know which companies are the most successful. To help throw light on the issue, and to do so more reliably than the plethora of league tables and charts produced by most business magazines, the London Business School have teamed up with The Economist to compile an assessment of the top performers of the 1980's. 相似文献

This paper examines the potential contributions of institutional theory and the collective strategies framework to assist managers in emerging industries in developing better means of addressing societal concerns. Lack of understanding and difficulties in communication between companies in the forefront of new technology developments and a society that is concerned about the environment have led to many of the problems facing the biotechnology industry. Measures intended to protect the environment from potential adverse effects have frequently restricted activities in the new biotechnology field, even though scientists are themselves convinced of the safety and control they exert over their new technologies. Collective strategies can be instrumental in stabilising certain aspects of the environment. Proper selection of issues and coordinated action can be helpful to all industry participants by informing public perceptions and government regulations and help insure that major environmental trends will evolve in a manner beneficial to all concerned. 相似文献

Cross-sectional and time-series tests using mimicking portfolios are used to assess the exactness of the APT with(out) a residual market factor. The first factor seems to be sufficient to span the efficient set, whether the model is estimated using (un)conditional variance-covariance matrices that are (un)adjusted for nonsynchronous trading. Although the conditional standard deviations of the mimicking portfolios significantly explain the time-variability of security volatilities, the residuals of the mean equation still exhibit heteroskedasticity. Similar results are obtained for portfolios of CAPM-betaranked securities, and for randomly selected individual securities. 相似文献

Concessional Amnesty and the Politics of Immigration Reforms 总被引:1,自引:0,他引:1
Nancy H. Chau 《Economics & Politics》2003,15(2):193-224
This paper establishes a political support model of immigration reforms. The analysis highlights the distinction between border enforcement and employer sanction measures in that the former can be more aptly characterized as an income transfer from employer to native labor interests, whereas the latter generates deadweight losses that are borne entirely by producers. We show that while amnesty may appear to run contrary to the original intent of the immigration reform, it may nevertheless facilitate rent capture by the politician by "wiping the slate clean" and reducing the deadweight loss of employer sanction measures. 相似文献

The paper addresses the question of whether trade restrictiveness impacts economic performance, via a trade restrictiveness index that is decomposable into a trade distortion and a domestic distortion component. The paper builds on the Anderson and Neary price index measure of trade distortion, in evaluating trade restrictiveness via a distance function approach. This is accomplished by adding a “dual” version to their trade restrictiveness price index, based on distance functions that scale output quantities. The authors compute the trade restrictiveness quantity index (TRQI) using a parametric frontier approach to model the production side of the economy, and a panel of information on the agricultural sector of a set of European Community countries. The results suggest that the use of TRQI makes a considerable difference to interpretations of the efficiency impact of agricultural trade policies in EC countries, as compared to policy‐oriented aggregates or result‐oriented measures of trade restrictiveness. 相似文献

Do the Forward Sales of Real Estate Stabilize Spot Prices? 总被引:1,自引:0,他引:1

We examine the effect of forward sale (pre-sale) activities on the volatility of spot prices in the real estate market. The
abundance of pre-sales data and major changes in regulatory control on the pre-sale market during the 90's in Hong Kong allow
us to undertake empirical tests using Hong Kong's real estate data. Our results show that the volatility of spot prices increased
significantly after forward sales were severely dampened by regulatory control measures introduced in 1994, but decreased
again when the measures were partly relaxed in 1998. The results contribute to the long lasting debate on whether the introduction
of a futures market reduces the volatility of spot prices. Previous studies were mainly conducted in markets with low transaction
costs, notably financial markets. By utilizing the unique regulatory changes in the pre-sale market of Hong Kong, we are able
to conduct an experiment on the conditional volatility of spot prices in a high information-cost environment, thereby shedding
light on the important role of forward housing contracts in providing price expectation information for spot trading. 相似文献

It is clear that customer-to-customer contact through informal social networking and more formal company-sponsored platforms, such as discussion forums, is an increasingly integral element in building brand communities. There are many benefits to this interaction, such as nurturing brand champions and ‘super users,’ and reduced service costs through customer-to-customer solutions for product problems. However, there are also hazards inherent in these largely unregulated communities, such as the potential damage of widely spread negative information, which may be based on fact or on malicious intent. Herein, we summarize the results of several years of research examining these communities in an attempt to understand why they succeed, what benefits can be extracted from them, and—in particular—how negative information emerging in these environments can be strategically managed. Based on a series of quantitative and qualitative studies, we identified several key drivers of online brand community success (i.e., intervention, conversion, value creation, and harvesting) and the different combinations of community players who must collaborate to achieve such success. Delving more deeply into the issue of negative information management, we find that the topic being discussed (i.e., core versus augmented product) and the validity of the claim greatly influence a firm's appropriate strategic response. Throughout this article, we offer managerial guidance on the most effective ways to develop primary brand communities that encourage loyalty, purchases, and positive word of mouth. 相似文献
