对中国信用卡消费群体特征的多元统计分析

本文在北京地区调查问卷的基础上设计了一套信用卡评价量表,通过多元统计中的因子分析、方差分析、卡方检验等手段分析信用卡评价变量与人口统计变量的相互关系,从量化的角度得出中国信用卡市场的基本现状和特点:信用卡各项服务的水平有很大的提升空间,开发潜力很大;信用卡的年费普遍过高;年轻群体相比于其他年龄群体对于信用卡的接受度、认同度、透支程度、及时还款程度都是最高的;信用卡的功能有待进一步开发;新功能的宣传所达到的效果较小;营销的细分市场应该主要通过透支额度和服务程度等来划分.最后文章还提出了相应的政策建议.     

Equity compensation and the sensitivity of research and development to financial market frictions

When financial market frictions exist, executives may have to decide which investment activities to reduce when internal funds decrease. Expenditures on research and development (R&D) may be particularly vulnerable because of the long-term nature of innovative activity. We find that equity compensation is associated with lower levels of firm R&D expenditures. Rewarding executives to incur more risk has little effect on R&D expenditures, but rewarding executives for higher returns reduces R&D expenditures and makes R&D expenditures more sensitive to financial market frictions. In contrast, cash compensation reduces the sensitivity of R&D expenditures to financial market frictions.

Pot of gold or winner's curse? An event study of the auctions of 3G mobile telephone licences in the UK

Commentators have suggested that the winning companies in the UK 3G mobile telephone auction overpaid for their licences. However, event‐study method using the market model under ordinary least squares (OLS), robust and structural time‐series estimation yields no systematic evidence of the ‘winner's curse’. Positive as well as negative one‐day wealth effects are observed amongst both winners and losers, and there is no lasting adverse market reaction to the winners, taken as a group. We conclude there is no case for easing the regulatory stance in the industry on grounds that the winners paid too much.     

Delegated trading and the speed of adjustment in security prices

Institutional trading arrangements often involve the portfolio manager delegating the task of trade execution to a separate division within the firm. We model the agency conflict that arises in this setting and show that optimal performance benchmarks often create an incentive to execute orders contrary to concurrent information flow. We hypothesize that aggregate contrarian trading resulting from widespread application of such benchmarks leads to delays in the assimilation of information in security prices. Using institutional trading data, we document the hypothesized contrarian trading pattern and relate the pattern to price-adjustment delays in the response of individual stocks to index futures returns. The evidence supports the assertion that delegated institutional trading contributes to these delays.

Conflicts of interest in sell-side research and the moderating role of institutional investors

Because sell-side analysts are dependent on institutional investors for performance ratings and trading commissions, we argue that analysts are less likely to succumb to investment banking or brokerage pressure in stocks highly visible to institutional investors. Examining a comprehensive sample of analyst recommendations over the 1994–2000 period, we find that analysts’ recommendations relative to consensus are positively associated with investment banking relationships and brokerage pressure but negatively associated with the presence of institutional investor owners. The presence of institutional investors is also associated with more accurate earnings forecasts and more timely re-ratings following severe share price falls.
