A test of the different implications of the overconfidence and disposition hypotheses

Under both the overconfidence and disposition biases, a positive relationship is predicted between prior returns and subsequent trading volume. However, theoretically the overconfidence and disposition effects have different implications on the relationships between the long- and short-position gains of traders and their subsequent buying and selling activities. We examine a unique dataset obtained from the Taiwan Futures Exchange which records all account-level trades and orders. Our data and methodology have the advantage of being able to empirically differentiate these two effects and we demonstrate that different types of traders exhibit different types and levels of behavioral biases.     

Information and communications technology use,e‐government,pain and stress amongst public servants

This paper examines information and communications technologies use, work intensity, technology preference, respondent characteristics, pain and stress in 240 New Zealand public servants across six agencies. In particular, we find that four variables are the most consistent predictors of pain—hours using a cell phone, stress, female gender and one's salary.     

The unrealized value of incentivized eWOM recommendations

While companies have recognized the perceived economic benefits of encouraging and managing electronic word-of-mouth (eWOM), the benefits may be understated. Companies take into account the influence on the audience. But, what about any effects on the person who communicates the eWOM? We explore the impact that incentivized eWOM has on communicator attitude. Using the saying is believing effect as our theoretical foundation, we suggest that providing eWOM induces a change in the communicator’s attitude. By generating and providing a biased recommendation, the communicator will believe the biased recommendation. Furthermore, the communicator is likely to remember the biased recommendation and will use it to update their attitude. We examine how valence of recommendations (negative versus positive) and the number of opportunities to recommend affect the change in attitude. Our findings indicate that providing recommendations changes communicator’s attitude. Implications of the results are discussed.     

Exclusivity and Control

We model competition between content distributors (platforms) for content providers, and show that whether or not content is exclusive or “multihomes” depends crucially on whether or not content providers maintain control over their own pricing to consumers: if content providers sell their content outright and relinquish control, they will tend to be exclusive; on the other hand, if content providers maintain control and only “affiliate” with platforms, then multihoming is sustainable in equilibrium. We show that the outcome under affiliation depends on the tradeoff between platform rent extraction (which increases in exclusivity) and content rent extraction (which increases in multihoming), and demonstrate that the propensity for exclusivity can be increasing, decreasing, or even nonmonotonic in content quality. Finally, if a content provider internalizes the effect of its own price on platform demand, we prove that a platform that already has exclusive access to content may prefer to relinquish control over content pricing to the content provider in order to reduce price competition at the platform level.     

Effect of Diversity of Large Wildlife Species on Financial Benefits to Local Communities in Northwest Namibia

There exist few quantitative assessments of the relationship between biodiversity per se and economic benefits at scales that are relevant for conservation. Similarly, the merits of Community-Based Natural Resource Management programs for both wildlife and people are contested. Here, we harness two databases, on wildlife surveys and financial benefits, to address these issues for communal conservancies in northwest Namibia. We use ordination methods to characterize the diversity and stability of large wildlife assemblages on conservancies, and demonstrate that diversity (but not stability) is an important explanator of conservancy financial benefits. Our results indicate that for this area of Namibia, biodiversity, as represented by large wildlife assemblages, has an important, positive effect on the tangible financial benefits that people derive from conservation programs.     

基于DEA的物流产业效率测度实证研究——基于我国31个省、市、自治区2008年投入产出数据

文章运用DEA的CCR模型和“超效率”(Super-Efficiency)模型,根据我国31个省、市、自治区2008年物流产业投入产出数据,利用Deap2.1和DEA-Sotver-J.V两个软件对物流产业投入产出效率进行实证研究.结果表明:以上海为代表的15个省市、自治区物流产业投入产出这到相对有效,以北京为代表16个省、市、自治区存在投入冗余,以内蒙古为代表的欠发达地区存在投入不足,产出效率偏低.同时,在非DEA有效省、市、自治区,表现出规模效率大于纯技术效率,进而影响了相对效率,文章对此进行投影分析,并以内蒙古为例,探讨了物流产业投入产出如何实施DEA效率改进.     

Success in social marketing

In a series of articles, Philip Kotler, first with Sidney Levy [11], then with Gerald Zaltman [12], and then singularly [8], has significantly broadened the scope of marketing management. Marketing strategy, according to Kotler, is pertinent in numerous areas in addition to its business application. This article is concerned with one particular area for the expanding application of the marketing concept— social marketing.The use of marketing strategy to achieve social objectives produces both similarities and differences to business applications. Comparing these similarities and differences should produce some insight about the potential success of social marketing.     

Synergy or New Information as a Source of Wealth Change in Acquisitions: The Case of Abandoned Bids

Potential sources of wealth change from acquisition are claimed to include both the opportunity for synergistic benefits and new information about the companies involved. New information may involve revaluation of previously undervalued or under-utilised assets. In the current study analysis is undertaken of the pattern of returns to targets in abandoned bids in the UK which were initiated during the period 1977–1986. The results provide evidence to support the view that acquisitions are undertaken not only for synergistic reasons but also to acquire previously under-utilised assets. The results also provide support for the hypothesis that the market for corporate control acts as one of the disciplinary mechanisms to improve corporate profitability.     

Strategic order splitting,order choice,and aggressiveness: Evidence from the Taiwan futures exchange

We investigate the strategic order‐splitting behavior and order aggressiveness of different types of traders using a unique dataset on the Taiwan Futures Exchange. By examining the trades and orders for each and every account, we find that, as compared with domestic institutional traders and individual traders, foreign institutional traders and futures proprietary firms are more likely to split their orders and it appears that the price adjustments after their trades are permanent. Foreign institutional traders and futures proprietary firms seem to be better informed, with their orders apparently being split so as to reveal their information on a gradual basis. Furthermore, we find that foreign institutional traders and futures proprietary firms use fewer market orders, choosing instead to submit aggressive limit orders, possibly due to their desire to make the most of their information advantage. © 2009 Wiley Periodicals, Inc.
