走市场之路必须强化社会信用体系

“信用”一词已成为近几年来全社会关注的焦点。信用是现代明的重要标志，是整个社会赖以生存和发展的基础。市场经济是信用经济，没有信用就没有秩序；没有信用，就没有市场。不讲信用，社会就无法维系；不讲信用，市场经济就荡然无存。然而．与此不相适应的是，无视信用，不讲信用，破坏信用比比皆是，     

内地与香港股票市场信用风险的比较

我国股市近几年一直在低谷中徘徊,其根本原因在于市场的各个主体—从上市公司、中介机构到监管者都存在不同程度的信用缺失,从而导致了投资者对股市信心的丧失。如果不消除股票市场的信用危机,那么投资者对内地股票市场长期稳定发展的信心就难以恢复。信心不恢复,股市就没有活力,就不会成为一个健康的、可持续发展的资本市场。内地股票市场的信用风险主要表现在上市公司信用危机和投资者信心危机这两个方面,而信用危机和投资者信心危机分别是由上市公司股权结构不合理和股票市场自身结构的不健全所造成的。因此,解决股票市场信用风险问题是我国股市健康发展的关键。     

我国信用缺失的原因及对策研究

市场经济是建立在发达的信用制度基础上的经济。信用促成了资源的再分配和利润率的平均化，加速了资本的积累和集中；信用是现代明的重要标志，是整个社会赖以生存和发展的基础。市场经济是信用经济，没有信用就没有秩序；没有信用，就没有市场。不讲信用，社会就无法维系；不讲信用，市场经济就荡然无存。然而，与此不相适应的是，在目前我国社会经济生活中，无视信用，不讲信用，破坏信用比比皆是；     

信用交易:解决中国证券市场缺陷的重要手段

引入信用交易制度，只是将已经存在的事实加以标准和规范，其在技术上不存在障碍。虽然信用交易有可能增大股市风险，但同样也是化解证券市场系统性风险的一种较好选择，只要设计得当，就可抑制股市投机，减少纠纷。同时，合理的证券信用交易体系也为股指期货、ETFs、指数基金等金融产品提供了必要的制度支持。为此，笔者分析各国信用交易模式，设计出符合我国实际的信用交易体系。     

社会诚信的缺失与重塑：经济学的视角

一、诚信缺失的成因(一)信用缺失的道德说随着我国改革开放的不断深入,传统的计划经济体制逐渐被市场经济体制所代替。在社会经济转轨时期,由于体制原因和人们思想认识上的偏差,在一定程度上造成了个人信用、企业信用乃至政府信用的缺失,并成为我国当前社会经济生活中的一个突出问题。以证券市场为例,新旧思想交替,观念错综复杂的现实为信用失衡提供了滋长的空间,道德约束的缺失已成为股市发展的重大缺陷。一个明显的现象是,尽管中国证监会每年都查处一批案件,但在业内并没有形成操纵股市可耻的观念,相

信用与经济金融小议

市场经济在本质上是信用经济。没有信用，就没有秩序，市场经济就不能健康发展。没有信用关系维系，就没有顺畅、安全、和谐、健康的交换关系，因而就不会有真正的市场经济，经济的快速、健康、持续发展就无保证。

A Note on Affordability and the Optimal Share Price

Despite the increase in institutional ownership, decreased trading costs, and increased real personal savings, we find that the average stock price is lower today than it was in the 1920s. In the aggregate, the propensity to split is a function of recent market performance, personal savings, and the desirability of appearing to be a small firm. Our results indicate that, after decades of inflation and the average stock price falling, splitting stocks to return to an "affordable" trading range must be rejected as an explanation. This suggests that other economic forces are behind splits, whether traditional or behavioral in nature.     

关于用双向交易模式来降低股市风险的相关分析

从2001年开始,中国股市进入到一轮长达4年的调整期。究其所以,就是因为中国股市实行的单向交易模式使得风险不断累积,最后集中爆发而形成的。要改变这种状况,就要变革这种单向交易模式,建立能够“卖空”个股的双向交易模式。

Stock Option Measures and the Stock Repurchase Decision

The major purposes of this study are two fold. First, we investigate whether or not the dilutive effect from stock options on the denominator of earnings per share is associated with the incurrence of stock repurchases. We use the FASB dilution and the economic dilution as the direct dilution measures and examine their relationship with stock repurchase decision. Second, we explore which of the extant measures of stock options can better explain the incurrence of stock repurchases. Six extant measures of stock options from previous studies are used: (1) the FASB's treasury-stock EPS dilution method, (2) the economic dilution measure based on Core, Guay and Kothari (2002), (3) the number of employee stock option exercises, (4) the number of stock option grants, (5) the number of total stock options outstanding, and (6) the number of exercisable stock options.Using a pooled cross-sectional sample from 1996–2000, we find a positive association between the likelihood of stock repurchases and the FASB dilution as well as the economic dilution in EPS, respectively. Thereby providing support for the undo-dilution hypothesis. The highest incremental explanatory power is found when we add the number of stock options exercisable to the baseline model. However, further analysis does not support the option-funding hypothesis suggested by Kahle (2002). We provide two explanations for why exercisable stock options better explain the stock repurchase decision.     

Market Response to Liquidity Improvements: Evidence from Exchange Listings

The study examines a sample of 895 stocks that moved from Nasdaq to the New York Stock Exchange or to the American Stock Exchange (Amex) between 1971 and 1994. We show how various measures of liquidity such as the bid‐ask spread, trading volume, and stock price precision improve in somewhat different ways upon transfer to NYSE (Amex). We also find that reductions in trading costs (percentage spread) and in pricing error volatility (Hasbrouck's σ₅) can explain most of stock market's positive response to exchange listing. Thus, liquidity has many facets and cannot be represented by the bid‐ask spread alone.     

Stock Splits and Liquidity: The Case of the Nasdaq-100 Index Tracking Stock

In an attempt to disentangle the signaling effect from the liquidity effect of stock splits, I examine the liquidity changes following the two‐for‐one split of the Nasdaq‐100 Index Tracking Stock. Since there can be no signaling with an index stock split, any difference between pre‐ and postsplit trading may be driven by liquidity but not signaling effects. I find that though the postsplit relative bid‐ask spread is higher and daily turnover is unchanged, the frequency, share volume, and dollar‐volume of small trades all increased after the split, indicating that the split improved liquidity for small trade‐sizes.     

The Reaction of Closed End Funds to Stock Distribution Announcements

This study examines the impact of stock split and stock dividend announcements made by closed end mutual funds. We argue that the asymmetric information / signaling hypothesis does not apply to mutual funds. Therefore, any announcement effects must be attributed to other factors such as the optimal trading range hypothesis. We find that closed end funds react no differently than other firms to stock distribution announcements; also, trading volume and turnover remain unchanged after closed end funds' ex-stock distribution days, while liquidity declines for other firms that distribute shares.

The Disparate Nature of Targeted Repurchases: Evidence from Long-Run Performance

Abstract:  We examine the announcement stock returns and long-run performance of 352 targeted repurchases from 1979 to 1998. For those repurchases of blocks that are non-control related we find a positive announcement stock price response and positive long-run stock performance indicating that these repurchases are timed to occur when the company's shares are undervalued and that the market underreacts to this signal. In contrast, for those repurchases of blocks that are control related we find a negative announcement stock price response and insignificant long-run stock performance indicating that these repurchases occur for a different reason. We conclude that control related repurchases are utilized solely to dismiss potential takeover bids and are not timed when the stock is undervalued.
