Random encounters and information diffusion about product quality

This paper explores how social interactions among consumers shape markets. In a two-country model, consumers meet and exchange information about the quality of the goods. As information spreads, demand evolves, affecting the prices and quantities manufactured by profit-maximizing firms. We show that market prices with informational frictions reach the duopoly price with full information at the limit. However, this convergence can take different paths depending on the size asymmetry between countries. In particular, when the country producing the low-quality good is relatively large, the single market does not immediately turn into a duopoly and can be temporarily trapped in a situation of price instability where no Nash equilibrium in pure (but only in mixed) strategies exists and prices can fluctuate between their monopoly and duopoly levels. It follows that the classical price-reducing effects of international trade may take longer to appear. In view of an intense globalization process, understanding how social meetings affect market outcomes is critical for understanding the performance of international economic integration.     

Manufacturer collusion: Strategic implications of the channel structure

We investigate how the structure of the distribution channel affects tacit collusion between manufacturers. When selling through a common retailer, we find—in contrast to the conventional understanding of tacit collusion that firms act to maximize industry profits—that colluding manufacturers strategically induce double marginalization so that retail prices are above the monopoly level. This lowers industry profits but increases the profit share that manufacturers appropriate from the retailer. Comparing common distribution with independent (exclusive) distribution, we show that the latter facilitates collusion. Despite this result, common retailing leads to lower welfare because a common retailer monopolizes the downstream market. For the case of independent retailing, we also demonstrate that contract offers that are observable to the rival retailer are not necessarily beneficial for collusive purposes.     

上市公司信息披露制度研究

作为证券法律制度之一的信息(本文专指会计信息)披露制度,它是维系证券市场健康发展的基本制度,也是证券监管部门实施监管的核心制度.一方面,它必须不折不扣地保障投资者的合法权益;另一方面,它又不能过分严苛地强制要求披露,以免抑制了企业通过证券市场筹资的兴趣.这种微妙的平衡是我国这个没有太多证券市场有效监督经验的国家不得不面对的问题,也是相关学者研究探讨的原因.     

Pay reference arbitration and the disclosure of information

This, the first of two articles, brings together two aspects of industrial relations: the practice of arbitration and the disclosure of information in the specific context of financial information disclosed at general pay claim references, making use of two case studies in which a relatively high degree of information was made available.     

Pay reference arbitration and the disclosure of information

This is the second of two articles which bring together two aspects of industrial relations: the practice of arbitration and the disclosure of financial information at general pay claim references. This article reports and discusses the findings of a mailed questionnaire survey of ACAS arbitrators and offers some general conclusions.     

Optimal disclosure of costly information packages in auctions

In an independent, private values, second-price auction with entry fees we discuss the way in which a seller should optimally spread costly information among the bidders. We find that marginal gross revenues do not generally behave monotonically in total information release. In the two bidder case, essentially, any asymmetric allocation of information dominates the symmetric information allocation. Even the bidder who gets less information is willing to pay a higher entry fee for asymmetric information allocations than for the symmetric one. His entry fee coincides with that of the better informed bidder. Losses from allocating an amount of information non-optimally can be substantial.     

Improving data quality during ERP implementation based on information product map

ABSTRACT

Poor Data Quality (DQ) is amajor culprit in the failure of ERP implantation. Previous DQ solutions focus more on technical approaches, ignoring the importance of seeking the root causes. Therefore, this paper proposes aprocess-driven DQ monitoring framework by Information Product Map (IPMAP). First, IPMAP is applied to visualizethe manufacturing process of critical information products. Then, the potential deficiencies that may arouse DQ problems are examined from the aspects of process and human. Finally, the corresponding DQ improvement strategies are put forward and validated in case study. The results indicate that the framework provides helpful guidance for promoting ERP DQ.

Factors influencing the quality of corporate environmental disclosure

Many firms choose to communicate their environmental strategies through voluntary environmental disclosures. This paper examines patterns in the quality of voluntary environmental disclosures made by a sample of around 450 large UK companies drawn from a diverse range of industrial sectors. The analysis distinguishes between five facets of quality, including the disclosure of group‐wide environmental policies, environmental impact targets and an environmental audit. We examine how the decisions firms face regarding each facet of quality are determined by firm and industry characteristics, and find the quality of disclosure to be determined by a firm's size and the nature of its business activities. Specifically, we find high quality disclosure to be primarily associated with larger firms and those in sectors most closely related to environmental concerns. In contrast to several recent contributions, we find that the media exposure of companies plays no role in stimulating voluntary disclosures.

On the informed seller problem: optimal information disclosure

We consider a revenue-maximizing seller who, before proposing a mechanism to sell her object(s), observes a vector of signals correlated with buyers’ valuations. Each buyer knows only the signal that the seller observes about him, but not the signals she observes about other buyers. The seller first chooses how to disclose her information and then chooses a revenue-maximizing mechanism. We allow for very general disclosure policies, that can be random, public, private, or any mixture of these possibilities. Through the disclosure of information privately, the seller can create correlation in buyers’ private information, which then consist of valuations plus beliefs. For the standard independent private values model, we show that information revelation is irrelevant: irrespective of the disclosure policy an optimal mechanism for this informed seller generates expected revenue that is equal to her maximal revenue under full information disclosure. For more general allocation environments that allow also for interdependent, for common values, and for multiple items, disclosure policies may matter, and the best the seller can do is to disclose no information at all.

Impact of regulation fair disclosure on the information flow associated with profit warnings

By implementing Regulation Fair Disclosure (RFD), the Securities and Exchange Commission's (SEC) intention is to ensure that all market participants have equal access to information, thereby preventing the flow of material information to analysts before other participants. We find that the negative valuation effects of profit warnings are attenuated following the introduction of RFD. This finding implies that since the implementation of RFD, the market appears to rely less on profit warning announcements. We also find that RFD has effectively reduced the leakage of material information to the analyst's favored clients, the market response to profit warnings is less negative when the issuing firm has multiple warnings, and when the warning does not apply beyond the prevailing quarter.     

我国企业环境信息披露的现状分析

伴随着科技现代化和经济全球化的步伐,人类的物质生活得到了极大改善,然而自然生态环境所遭受的破坏也不容小觑。如何应对当前的环境危机,突破遏止人类发展的"瓶颈",已成为亟待解决的问题。企业作为社会的基本单元,既是社会财富的直接创造者,又是环境污染的主要制造者。作为环境的重要影响者之一,企业理应积极践行可持续发展观,主动对外披露环境信息,切实承担起自身的环境责任。随着国家对环境问题的日益重视,环保立法不断加强,我国企业的环境信息披露状况也有了明显改善。但与西方发达国家相比,无论是在披露内容、披露形式还是披露效果方面,情况仍不容乐观。
