样板间:ChART Contemporary的策展实验

寻找房子——在我们开始样板间策展之前2009年的时候我们面临着两项挑战,这两项挑战促使我们重新定义了ChART Contemporary的策展轨迹。其一是我们感受到了全球经济衰退的影响,     

Switching Costs in Two‐Sided Markets

In many markets, there are switching costs and network effects. Yet the literature generally deals with them separately. This paper bridges the gap by analyzing their interaction (or ‘indirect bargain’) in a dynamic two‐sided market. It shows that in the symmetric equilibrium, the classic result that the first‐period price is U‐shaped in switching costs does not emerge, but instead switching costs always intensify the first‐period price competition. Moreover, an increase in switching costs on one side decreases the first‐period price on the other side. Policies that ignore these effects may overestimate the extent to which switching costs can reduce welfare.     

A Study on Pollutant Emission Through Gas Consumption in the Hong Kong Hotel Industry

A survey of 11 hotels in Hong Kong was carried out to collect three years' energy consumption data. Regression analysis indicated that gross floor area was a major and statistically acceptable factor in explaining the gas consumption in new hotels. Based on past consumption data and some established pollutant emission factors, the amount of sulphur dioxides, nitrogen dioxides, carbon dioxides and particulate created by the Hong Kong hotel industry's gas usage during a 10-year period from 1989–1998 was estimated. The study predicts the increase in these amounts in 1999–2003 accompanying the rise in the number of hotels. The findings indicate that emissions will rise by nearly 40% in the next few years, requiring urgent discussions. The study also finds that a heat pump running on coal-fired electricity and with a coefficient of performance (COP) greater than 3 could produce lower level emissions than a gas-fired boiler. It is further suggested that an effective method to reduce the emissions is to substitute naptha with natural gas as the fuel for generating town gas and electricity. We believe the hotel industry should adopt a more proactive approach to reduce gas usage and propose the inclusion of environmental reporting in trade journals.     

A Comparative Study of the Benefits of Applying Target Cost Contracts Between South Australia and Hong Kong

This article aims to identify and analyze the key benefits of adopting Guaranteed Maximum Price and Target Cost Contracts (GMP/TCC) over and above the traditional lump‐sum contractual arrangement through an empirical questionnaire survey conducted in South Australia and compared with the findings in Hong Kong. The Mann‐Whitney U Test indicated differences in perception between the two groups of respondents on the majority of the identified benefits. The study has provided an in‐depth understanding of the perceived benefits of the GMP/TCC scheme, hence leading to a wider application of those alternative integrated procurement strategies in both regions for reference by the construction community at large.     

‘An Examination of the Ethical Commitment of Professional Accountants to Auditor Independence’

This research explores the relationship between work context and professional ethics. Specifically, we analyze through an online survey of professional accountants the degree to which changing work conditions have altered individual accountants’ commitment to the core professional value of auditor independence. We argue that certain changes in the condition of work have made some categories of accountants more susceptible to the logic of commercialism rather than the logic of professionalism. We find general support for this argument. We observe that accountants working outside of public accounting have a higher commitment to independence than do accountants working in the context of public accounting firms. We further observe that accountants in large international accounting firms (i.e. the “Big Four”) report lower commitment to auditor independence than do others in public accounting. And we observe that older accountants report stronger commitment to auditor independence. One finding, however, contradicts our general thesis. We find that commitment to one’s client does not necessarily result in a loss of commitment to the core professional value of independence. We conclude that changes in the context of work have contributed to the demise of ethics among professional accountants and suggest that further research be done to elaborate the relationship between client commitment and independence commitment.     

A Study of the Ethical Performance of Foreign-Investment Enterprises in the China Labor Market

This paper analyses the ethical performance of foreign-investment enterprises operating in China in comparison to that of the indigenous state-owned enterprises, collectives and private enterprises. It uses both the deontological approach and the utilitarian approach in conceptualization, and applies quantitative and econometric techniques to ethical evaluations of empirical evidences. It shows that according to various ethical performance indicators, foreign-investment enterprises have fared well in comparison with local firms. This paper also tries to unravel the effect of a difference in business culture and competitive market forces on ethical performance by comparing the behavior of foreign-investment enterprises with that of the indigenous state-owned enterprises and collectives on the one hand, and with that of the indigenous private enterprises on the other.     

The effects of merchandise coordination and juxtaposition on consumers’ product evaluation and purchase intention in store-based retailing

Many retailers attempt to juxtapose and coordinate complementary products in their stores on the basis of key attributes because good coordination of complementary items can provide consumers with relevant information for their evaluation of individual products. In addition, the aesthetic appeal and the social impression that good coordination offers can be transferred to the products themselves. On the basis of these theories, the authors test the effects of merchandise coordination and juxtaposition (vs. separation) on consumer behavior using actual clothing items as stimuli in a laboratory setting. The authors find that coordination affects consumers’ evaluation of and purchase intention toward a target item only when the item is juxtaposed with a complementary item. This effect can be explained by the aesthetic response of consumers to and their social impression of a grouping of the items. Furthermore, in comparison with displaying the two items separately, juxtaposing them in a poorly coordinated manner appears to depress the target item's evaluation, though juxtaposing them in a well-coordinated manner does not seem to improve the evaluation.     

Changes in the value relevance of accounting information over time: Evidence from the emerging market of China

We investigate the changes in the value relevance of accounting information among Chinese firms over the past two decades, during which accounting reforms are launched to provide decision makers with increased disclosure and higher quality financial information. We also investigate the factors that differentiate firms showing significant value relevance improvement from firms showing little improvement. We find increases in the value relevance of some financial variables and decreases in others, which suggests that accounting numbers help to explain the pricing process of stock shares although at different levels. In addition, we find that value relevance improvements are more pronounced for smaller firms, firms with lower growth rates, and those with greater asset tangibility. We also document that value relevance improvements are generally lower in an exuberant stock market. These results have implications for a variety of information users and policy makers in emerging countries which are reforming their accounting systems.     

On automated e‐business negotiations: Goal,policy, strategy,and plans of decision and action

In recent years, there has been increasing interest in automated e‐business negotiations. The automation of negotiation requires a decision model to capture the negotiation knowledge of policymakers and negotiation experts so that the decision‐making process can be carried out automatically. Current research on automated e‐business negotiations has focused on defining low‐level tactics (or negotiation rules) so that automated negotiation systems can carry out automated negotiation processes. These low‐level tactics are usually defined from a technical perspective, not from a business perspective. There is a gap between high‐level business negotiation goals and low‐level tactics. In this article, we distinguish the concepts of negotiation context, negotiation goals, negotiation strategy, and negotiation tactics and introduce a formal decision model to show the relations among these concepts. We show how high‐level negotiation goals can be formally mapped to low‐level tactics that can be used to affect the behavior of a negotiation system during the negotiation process. In business, a business organization faces different negotiation situations (or contexts) and determines different sets of goals for different negotiation contexts. In our decision model, a business policymaker sets negotiation goals from different perspectives, which are called goal dimensions. A negotiation policy is a functional mapping from a negotiation context to some quantitative measures (or goal values) for the goal dimensions to express how competitive the policymaker wants to reach that set of goals. A negotiation expert who has the experience and expertise to conduct negotiations would define the negotiation strategies needed for reaching the negotiation goals. Formally, a negotiation strategy is a functional mapping from a set of goal values to a set of decision‐action rules that implement negotiation tactics. The selected decision‐action rules can then be used to control the execution of an automated negotiation system, which conducts a negotiation on behalf of a business organization.
