上市公司业绩预告与股票收益率的经验研究

运用上市公司财务与市场数据，对业绩剧变公司的业绩预告的特点、影响因素及业绩预告对股票价格影响的实证研究发现，业绩预告披露的可能性与业绩变动、基金持股比例、公司规模等因素有关，与风险、前十大股东持股比例等因素无关；业绩预告披露、年度财务报告披露期间的异常收益率与ROE变动比率、资产规模、信息披露细致程度等因素有关。在年报披露期间，业绩预告披露与否对异常收益率有显著影响，业绩预告会在一定程度上削弱年度财务报告信息对该公司股票的利空、利好效应.

An exploratory study of operational reasons to budget

Budgets are used widely but criticized, mainly for performance evaluation reasons. We find that organizations regard budgets as more important for planning and control than evaluation, thus proposing a rationale for their continued use irrespective of evaluation‐based criticisms. This finding is also important, because most extant budget research focuses on evaluation, suggesting a potential disconnect between budget research and practice. We also find that rolling forecasts are used in tandem with the annual budget in most organizations, and for the same reasons. This was unexpected, as coexistence suggests their adoption for different reasons.     

The Lowest Supply and Demand of Engineering Officers of National Vessels in Taiwan

This article is based on the number of engineering officers from 1994 to 2000 in Taiwan, and adopts a 6-year moving average to work out the transition probability of engineering officers and to construct an absorbing Markov Transition Matrix to forecast the terms of seniority and annual supply in each hierarchy. In order to estimate the minimum number of vessels needed, this article also employed the quantity of demand for imported consumer goods from 1994 to 2000 in Taiwan and applied a Grey model to predict the annual quantity of demand for imported consumer goods. Furthermore, this article estimated the minimum number of demand for engineering officers according to the minimum number of vessels needed. In addition, this paper used cross-analysis to investigate the manpower supply and demand of engineering officers in Taiwan and obtained some important results, which can be valuable references for pertinent authorities.

Globalization, Financial Volatility and Monetary Policy

Recently it has often been claimed that globalization eases the job of central banks as it helps to tame inflation. This is used to argue that central banks (particularly the ECB, referring to the objectives as laid down in the EU Treaty) could or should reduce their efforts in the fight against inflation in favor of supporting the general economic policies of the governments. This paper takes a critical look at this argument, pointing to the structural changes associated with globalization and to the corresponding increase in uncertainty by which the central banks are affected. As an example of this, the increase in financial volatility is analyzed and explained as the result of optimal portfolio allocation, and its implications for monetary policy are discussed.
