The market speed of adjustment to new information

A definition of market adjustment is proposed in terms of the time it takes market attributes to reflect new information. Properties of the proposed definition are discussed. In order to operationalize the concept, a statistical method is introduced to estimate the adjustment times. Empirical examples are used to illustrate the proposed method. Some possible economic interpretations are given. The properties of the estimator are also investigated by simulation and analytical methods.     

Innovation,information and long-term growth

Short-term and partial analyses have led to overpessimistic predictions (non-conjunctural unemployment, decline of certain countries, and a slowdown in creativity). A more general approach is based on the idea of industrial revolution: the neolithic—cultivation and domestication; in the 19th century—coal, steel, railways; in the mid—20th century—petrol, cars, etc. A fourth revolution is beginning (electronics, information sciences, telematics, biotics, aquaculture, solar power etc), but this is still in an embryonic phase, whereas earlier revolutions are in their mature stage. An interpretation based on the information sector can lead to a certain pessimism. This can only be avoided by a broader definition of the economy (pattern recognition) in which man, and human investment, have an equal place alongside material investment.

Dealer attention,the speed of quote adjustment to information,and net dealer revenue

Using trade and quote data from the NYSE, we examine the relation between dealer attention, dealer revenue, and the probability of informed trade. We find that dealer revenue net of losses to better-informed traders in NYSE stocks is positively related to the speed at which quotes adjust to full information levels. The speed of quote adjustment is faster for stocks with greater dealer attention, as measured by a stock’s relative prominence at its post and panel location on the NYSE floor. The level of dealer attention in turn is positively related to a stock’s probability of information-based trading. The results are consistent with a theoretical model we derive in which dealers trade multiple securities and must optimally allocate their limited attention to monitoring order flow to minimize losses to better-informed traders.     

知识贸易视角的高校助学贷款创新

我国高校助学贷款是一个涉及众多利益主体的复杂系统行为,实施过程中出现了多目标冲突下的困境.现代大学与助学贷款的特殊经济性质决定了高校助学贷款主要是知识贸易贷款,而金融产品的可分性使其业务主要是知识贸易金融合约,具有个人和社会双重知识型人力资本投融资性质,而且存在知识市场失灵的可能.助学贷款的成功发展既需要银行借助细分产品加强业务管理,参考知识周期确定还贷期限,依托信息优势拓展协同贷款,根据风险来源确定担保方式,同时也需要政府为平衡贷款利率实施差别财政补贴.高校助学贷款实质是基于知识贸易的教育金融工具和政策工具.

Innovation budget pressure,quality of IS information,and departmental performance

Evidence suggests that innovation budgets need to be carefully managed due to increasingly demanding markets, changes in technology and greater international competition. Companies often express concern over the magnitude of their innovation costs, potentially inhibiting them from investing in new product development. This has given rise to concern for innovation budget pressure, which focuses on constraining costs to budgeted levels even if further expenditure might facilitate enhancements in terms of the quality and speed of the innovation process. However, suggestions have been made that decision systems in these settings could benefit in terms of performance outcomes from improvements in information system (IS) information quality. The literature suggests that the impact of quality of IS information on departmental performance is dependent on whether there is an emphasis on innovation budget pressure. The results of this study show that when innovation budget pressure is high, quality of IS information enhances performance. In contrast, when the emphasis on innovation budget pressure is low, quality of IS information does not promote performance.     

Costing efficiency at the central office of information (COI)

The move from vote‐funding to repayment created uncertainty for staff and managers in the Central Office of Information (COI). Financial systems that had been retrospective had to be replaced with systems that captured key numbers and enabled forecasts to be made and performance against targets to be measured.

COI has developed management accounting and unit costing in ways that have enabled the organization to meet targets and succeed as an Executive Agency and trading fund.

The presentation of financial information at corporate Web sites

The advent of the World Wide Web has provided a new avenue for companies to communicate with current and potential investors. Our study investigates corporate Web site financial disclosure practices. We evaluate and compare the Web site disclosure levels of 17 industries, and summarize the frequencies with which a variety of financial disclosure items are found. Our examination identifies several practices that raise potential concerns for the accounting profession. In particular, we investigate annual report excerpts tailored for Internet users and identify information found at Web sites that may increase disclosure risk. We also discuss issues associated with locating and using Web site data.     

Dissemination of information for investors at corporate Web sites

We extend the limited prior research on Internet financial reporting by providing insights into dissemination of two types of financial information at corporate Web sites. One type consists of reports that already have been filed with the SEC (i.e. required filings). The second type is all other (voluntary) information for investors. In doing so we investigate whether Web-based dissemination of both types of data can be explained by theories of incentives to voluntarily disclose information via more traditional means such as meetings or conference calls with analysts. We use regression analysis to test hypotheses that link the variation in the information disseminated through corporate Web sites to factors thought to influence voluntary disclosure of financial information. Presence of required items is significantly associated only with size and a proxy for information asymmetry, while voluntary information item disclosure is associated with variables proxying for size, information asymmetry, demand for external capital, and companies’ traditional disclosure reputations. Our results confirm that incentives motivating initial voluntary disclosure also explain the subsequent dissemination of voluntary material.     

Innovation links,information diffusion,and return predictability: Evidence from China

Based on the activities of patent citation in China, a novel type of cross-firm innovation links is generated to investigate the gradual diffusion of information along the innovation chain via tests of cross-sectional return predictability. Various signals are created to represent the value of the information contained in the innovation links; these signals are demonstrated to have robust cross-predictability for stock returns in both the cross-sectional regression model and portfolio strategies. The effect of predictability is found to be stronger for stocks with high institutional ownership and analyst coverage. Considering the minimum number of steps required to establish the cross-firm linkage, innovation links are further partitioned to represent different proximity of the linked firms. It is then found that information diffuses faster across closely-linked firms than across distantly-linked firms. Sophisticated investors are found to be able to properly process the relevant information and benefit from innovation links.

Components of execution costs: evidence of asymmetric information at the Mexican Stock Exchange

Immediate execution costs for stocks trading at the auction market of the Mexican Stock Exchange (MSE) are five times higher than those for similar NYSE stocks. The source of the trading cost differential is asymmetric information. Mexican stocks are associated with a substantially larger asymmetric information component of the spread (2.76 cents per dollar) than their matched NYSE counterparts (0.28 cents). Results indicate that differences in asymmetric information are not related to stock characteristics, number and sophistication of security analysts, listing and disclosure requirements, ownership restrictions, and voting rights.

Conditioning manager alphas on economic information: another look at the persistence of performance

This article presents evidence on persistence in the relativeinvestment performance of large, institutional equity managers.Similar to existing evidence for mutual funds, we find persistentperformance concentrated in the managers with poor prior-periodperformance measures. A conditional approach, using time-varyingmeasures of risk and abnormal performance, is better able todetect this persistence and to predict the future performanceof the funds than are traditional methods.

Public‐private partnerships versus traditional procurement: Innovation incentives and information gathering

A government agency wants a facility to be built and managed to provide a public service. Two different modes of provision are considered. In a public‐private partnership, the tasks of building and managing are bundled, whereas under traditional procurement, these tasks are delegated to separate private contractors. The two provision modes differ in their incentives to innovate and to gather private information about future costs to adapt the service provision to changing circumstances. The government agency’s preferred mode of provision depends on the information‐gathering costs, the costs of innovation efforts, and the degree to which effort is contractible.
