基于社会责任角度对垄断国企上缴利润的思考

垄断企业得到垄断的超额利润,会导致社会贫富差距进一步分化,造成社会福利的损失。我国垄断企业的超额利润长期稳定存在。从增加社会福利的角度考虑,应加强垄断国有企业对垄断超额利润的上缴,并构建相应的垄断国企上缴利润的制度框架,实现有效的收入再分配。这是基于社会责任对垄断国有企业提出的要求。

‘Adopt a Hypothetical Pup’: A Count Data Approach to the Valuation of Wildlife

The willingness to pay (WTP) for a coyote conservation program is estimated using a novel payment-vehicle, based on how many ‚problem’ coyotes respondents would be willing to sponsor for a year. This hypothetical scenario mimics an increasingly popular type of actual market. Data from a phone survey conducted in Prince Edward Island are analyzed using count data models that consider different processes explaining zero responses and the level of positive responses. This is particularly important in the case of coyotes, often regarded as an economic bad. Estimates of WTP per coyote per year around $18–$22 and annual WTP per contributor of about $46–$57 are obtained.      

A Comparative Analysis of Auditor, Manager and Financial Analyst Interpretations of SFAS 5 Disclosure Guidelines

This study examines empirically whether financial analysts (users), as well as managers (preparers) and external auditors ascribe different interpretations to the SFAS 5 disclosure criteria. We find: (1) financial analysts are, on average, more conservative than managers and auditors in their numerical interpretations of both the 'remote' and 'probable' verbal phrases; (2) managers and auditors share very similar numerical interpretations of these verbal phrases; (3) audit partners' numerical interpretations of the 'remote' region are between those of managers and users, whereas audit managers align their numerical interpretations with those of managers. One danger is that preparers of financial statements may omit loss contingency information that users consider valuable.     

Mobile technology usage and B2B market performance under mandatory adoption

This paper investigates the relationship between mandatory adoption of mobile information technology and market performance in the business-to-business (B2B) setting. This study presents and tests the B2B technology satisfaction model (TSM), including perceived loss of control as the mandatory technology acceptance-specific variable. The results of this study reveal that integrating perceived loss of control with user satisfaction and the TAM (technology acceptance model) in a single model can better explain the B2B market performance model. The empirical results suggest that perceived loss of control has a negative effect on user satisfaction and perceived market performance is influenced by user satisfaction and perceived usefulness. Managerial implications of the study are discussed.
