我国股票市场费雪效应的误差修正模型检验

持有股票是否能够预防通货膨胀,这要依赖于股票市场是否存在费雪效应。目前,研究费雪效应的文献一般将股票市场作为一个整体来看待,主要考虑时间因素和通货膨胀本身的特点对费雪效应的影响。除了考虑时间和通货膨胀因素外,本文还按照金融资本和总资本比率的高低来选择不同的行业作为研究对象,旨在研究费雪效应与股票所在的行业之间的关系。经研究,本文得出费雪效应与股票行业存在显著的联系,即费雪效应一般只存在于金融资本比率不太高的行业。     

提高农产品价格对促进农民增收作用的有限性研究

尽管农产品价格上涨对农民增收存在种种促进效应,但实践证明,提高农产品价格对促进农民增收的作用是有限的,而且靠提高农产品价格来刺激农业生产供给和提高农民收入的办法越来越难以为继。因此,要解决农业比较利益偏低的问题,必须通过农业的发展,形成农产品价格优势的经济效益基础。     

The Signaling Impact of Low Introductory Price on Perceived Quality and Trial

Economic signaling theory suggests that consumers interpret price withinthe context of market conditions. Under specific conditions it predicts thatlow price may signal high quality. Results from an experiment designed totest the behavioral assumptions underlying this prediction indicate thatconsumers intentions to purchase conform to the predictions of economicsignaling theory, but their judgments of product quality do not. The resultssuggest that consumers' response to signals may be more complex thanpreviously shown.     

The Effect of Product Innovation,Promotion, and Price on Consumer Switching to Private Labels

The channel conflict that exists between retailers and manufacturers of branded products has dynamically shifted as large retailers have expanded their offerings of private label products. This study investigates the ability of consumer packaged goods companies to exert influence in the channel by testing which marketing initiatives implemented by manufacturer brands are more efficient in preventing consumer switching to private labels. We use a hazard model to simultaneously measure the effects due to product innovation, promotion, and price on consumer switching and how strong those effects are. We find that as expected product innovation, promotion, and price exert a negative effect on the consumer likelihood of switching to private labels. However, we find the strongest effect on promotion suggesting the importance of understanding how consumers perceive value in the national brands offer.

顾客参与新产品开发的绩效影响:产品创新类型的调节效应

顾客参与企业新产品开发对新产品开发绩效有着重要影响,在处于转型经济背景下的中国进行相关研究更有着极为重要的战略意义。文章以B-B市场中的制造企业为研究对象,构建了以产品创新类型为调节变量的顾客参与对新产品开发绩效差异化影响的调节效应模型。研究表明,顾客参与对新产品开发时间绩效与创新绩效的积极影响会受到产品创新类型的调节作用;但产品创新类型对顾客参与和财务绩效关系的调节影响不显著。     

The Effect of Sport Sponsorship Programs of Various Sport Events on Stock Price Behavior During a Sport Event

This paper examines sporting event's spillover effect to investor's behavior through event study analysis using the GARCH (p,q) model, focusing on the stock price effects of a sport sponsorship program during and after a sporting event. Studying stock price behavior during a sporting event is attempted for the first time in the marketing and sponsorship literature. First, we provide some summary points from the review of 40 research works and interpretive claims, based on a conceptual and theoretical framework. Second, we consider daily stock returns of 28 listed companies that have sponsored 15 major sports events during the period 2000–2009, in order to examine the effect of major sporting events on sponsors’ stock returns and volatility. The three research hypotheses are supported. Research results show that stock returns and volatility changed significantly during and after the sporting event compared to pre-event period. Results show that stock price effects caused by sports events’ sponsorship programs are firm-specific, as well as sporting event-specific. The findings of this study are of high value for promotion managers as it allows them to become more critically aware of the practical wisdom of sporting events.     

基于美德经验的极端风险溢出效应检验

本文运用GARCH模型和主成分分析方法,从分析极端风险溢出机理出发,实证研究国际金融危机前后美国股票市场、债券市场及金银市场对德国股票市场的风险溢出效应,发现标准普尔500指数对德国法兰克福DAX指数日收率不仅存在极端风险溢出效应,且在金融危机前后的三个时期都存在风险溢出效应;而美国13周国债指数日收益率对德国法兰克福DAX指数日收益率在金融危机前后的三个时期都不存在风险溢出效应;费城金银指数的日收益率只在金融危机时期对德国法兰克福DAX指数日收益率产生风险溢出效应,即仅存在极端风险溢出效应。     

Product Regulation and Stock Prices: The Case of the US Food and Drug Administration

This study focuses on the stock market effects associated with the announcements of product approvals, denials and recalls by the US Food and Drug Administration (FDA), and the impact of product approvals on research and development expenditures (R&D) and forecasts of earnings by Value Line. When the FDA announces approvals, the shareholder wealth of affected firms increases significantly. The announcements of denials and recalls by the FDA are associated with stock price declines. The stock price impact of recalls is dependent on whether the firm voluntarily withdraws a product or if the withdrawal is mandated by the FDA. Specifically, voluntary recalls are not associated with a change in stockholder wealth, while FDA mandated recalls are associated with decreases in stock price. In addition, we find that partial product recalls have a smaller impact than total recalls. An examination of the effects on competitors' stock price reveals losses when the FDA announces an approval or a recall, but no imt for a d. An analysis of changes in risk around FDA decisions suggests that, on average, betas do not change around approvals, recalls or denials. In addition, our results suggest that announcement period stock price behavior is unrelated to risk changes except for approvals where returns are positive and significant for firms with either increasing risk or no change in risk. We also find that approvals are associated with increases in R&D and forecasts of earnings for the sample firms, with returns to stockholders upon announcement of the approval being related to the increases in R&D and short-term earnings forecasts.     

The Moderating Effect of Product Category Knowledge and Attribute Importance on the Attraction Effect

This paper explores the moderating effect of product category knowledge and attribute importance on the attraction effect. The results of our study point to several boundary conditions of the effect. For consumers who have a moderate level of product category knowledge, and for consumers who assign more importance to one product attribute over the other, the attraction effect was strongest. In contrast, the attraction effect was diminished, in some cases to insignificant levels, for consumers with a high or low level of product category knowledge, and for consumers who consider both product attributes about equally important.     

The Effect of GATT/WTO on Export and Import Price Volatility

Despite much interest and discussion concerning the trade‐promoting effects of membership in multilateral trade agreements, little is known about the effect of membership on world trade prices. This paper fills this gap by studying the effects of membership on export and import price volatility. We document a surprisingly strong and robust empirical regularity: GATT/WTO membership reduces the volatility of prices over time for both import and export countries, with similar results found for free trade agreements. We show that results are not driven by sample selection or endogeneity concerns and that the effect is captured by members subject to rigorous accession procedures.     

外国直接投资对我国税收正负影响的实证分析

本文实证分析了外国直接投资对我国税收的正负影响.结论认为,虽然外国直接投资极大地促进了我国税收的增长,但给予外资较高程度的税收优惠也在一定程度上侵蚀了我国的税基,减少了我国的税收收入.由于税收优惠并非吸引外资的显著因素,有必要分步骤地进行现有税收制度改革,最终统一内外资企业的税收制度.

The Impact of Innovativeness and Development Time on New Product Performance for Small Firms

Timing is becoming a new source of competitive advantage. The business press extols the benefits of faster product development. This paper examines whether competitive advantage can be gained by reducing development time across all types of new products or whether this advantage is restricted to certain types of new products. It proposes that product innovativeness moderates the relationship between development time and initial market performance. A survey of 110 small manufacturing firms in computer related industries supports the hypothesis. The survey findings indicate that a firm must guard against over- or under-development of the new product since product innovativeness was found to influence the impact of development time on market performance. The implications for managers are: beware of bringing a new product that is too much, too early or too little, too late.     

高管团队价值观、团队氛围对冲突的影响

文章实证分析了高管团队成员的社会价值观和团队氛围对冲突的影响。结果表明,高管团队的绩效观和集体主义观与任务冲突有正向联系,集体主义观异质性和绩效观异质性抑制任务冲突,利己权力观异质性引起任务冲突。研究发现高管团队开放性和信任构成的团队氛围与任务冲突有正向联系,总经理的集体主义导向与任务冲突正相关。研究没有发现价值观与关系冲突联系的直接证据,关系冲突更可能与情绪因素相联系。

印花税变动对股票波动率和换手率的影响——基于投机市场的分析

运用残差为一阶自回归的随机效应模型,考察中国证券市场三次印花税调整对股票波动率和换手率的影响,结果发现以印花税作为政策工具,监管方并不能有效实现其目标.税率上调导致换手率降低,波动率中期增加、长期减少;税率下调则可能引起换手率、波动率增加,也可能引起两者减少.结合意见分歧投机泡沫理论,尝试给出合理解释.
