中国汇市与股市的信息传递关系——基于股市"牛熊"特征的比较研究

关注金融市场间的风险传染性对于防范金融风险、提高监管效率有着重要的意义.运用多元GARCH模型研究汇改后(2005年7月22日到2009年8月31日)中国股票市场与外汇市场的信息传导过程,其结果表明汇市的波动风险会传染给股市,而股市的波动则不会对汇市产生明显影响,股市与汇市之间的溢出效应是非对称的.分阶段研究显示,在牛市阶段,股市对汇市存在微弱的信息溢出效应;熊市阶段,只存在单向溢出效应,随着时间的推移,汇市对股市的溢出效应逐渐增强.     

信用信息价值的经济分析

一、信用信息的价值 信用交易是以交易对象的所有权和使用权相分离为前提的，对授信方来说，是以利息获取（收益）对交易对象使用权的出让；对受信方来说，是以利息支付（成本）对交易对象使用权的购买；并且信用交易不是即期一次性完成的（合约的签订只是表明交易双方对各自权利义务的承诺），而是在信用交易双方约定的时间内、     

信息传递效率、货币传染与东亚汇率波动溢出分析

本文运用Cheung和Ng交叉相关系数方法,对东亚六国货币①——人民币、日元、韩元、泰国铢、新加坡元和林吉特的名义美元汇率波动溢出进行检验,发现东亚汇率波动溢出普遍存在且具有不对称性和多层次溢出特征。实证结果还表明,日元交易商能更加有效处理来自人民币、韩元、泰铢、新加坡元和林吉特五种货币的信息,而人民币交易商对处理来自日元、泰铢、新加坡元等货币的信息效率不高。     

双重上市股票的价格信息传递——基于内地香港双重上市股票的实证分析

本文选取2003年到2007年4月的内地、香港双重上市股票为样本，运用似不相关（suR）方法实证考察两个市场之间的价格信息传递情况。研究发现：个股日内收益受A股市场大盘影响比同一只股票在香港市场受恒生指数的影响要大；股票价格信息主要由内地流向香港；A股的目内收益显著影响了同一天香港的日内收益，而A股的日内收益对香港隔夜收益的影响相对较弱。     

信号传递和信息甄别模型在管理者收购中的应用

由信息不对称导致的事前的逆向选择和事后的道德风险是我国管理者收购未能达到预期目标的根本原因,因此本文尝试利用信号传递和信息甄剐模型来缓解和消除管理者收购中逆向选择和道德风险的负面影响。     

内幕交易、股价信息含量与市场监管效力——基于中国A股市场的分析北大核心CSSCI

本文针对非法内幕交易对股价信息含量的影响进行实证检验,研究表明:就整体而言,内幕信息通过买卖双向非法内幕交易使交易发生日的股价信息含量显著提高,加剧市场信息不对称程度;并购重组类的内幕信息对内幕交易发生日的股价信息含量的影响最显著,而经营合作投资类的内幕信息影响最不显著;从对内幕交易监管的视角,现行实施的监管法规无法有效遏制由内幕交易造成的市场信息不对称性,且笼统的'盈罚比'监管方法无法有效遏制对公众投资者利益影响最大的内幕交易行为,监管机制有效性仍不足.

完善我国农村金融体系的经济学研究

农村金融是现代农村经济的核心.在我国,农村经济最基本的生产要素(土地、劳动力和资本)中,资本最为稀缺.长期以来,我国农村金融体系存在着严重的缺陷,使得农村经济发展得不到金融行业的强力支持.在此过程中.农村信用社一卣没有准确的定位.更没有充分发挥出其应有的金融功能.要推动现代农业经济的进步,建设社会主义新农村,最终解决"三农问题".就必须研究造成农村金融体系缺陷的根本因素,并在此基础上探索适合我国国情的农村金融体系完善途径.     

A note on noise in the market for bankrupt firms' securities

The well-documented phenomena of departures from the absolute priority rule (APR) have provoked an important public policy debate over their consequences. Some scholars argue that APR violations increase economic efficiency because they play an important role in the avoidance of inefficient liquidations and also mitigate inefficient risk incentives. Another group argues that APR violations should be abolished because they add greater uncertainty to the security valuation process; that is, they increase noise in security prices. To date, however, no evidence has been presented on the issue of how much noise APR violations add. We develop a theoretical model that allows an empirical test of the effect of APR violations on noise; our results suggest that APR violations importantly increase noise. Indeed, at least 30 percent, and as much as 85 percent of the noise in security prices may be attributable to APR violations. This does not suggest that the beneficial effects of APR violations are nonexistent or unimportant, but it does imply that failing to account for the effect of APR violations on noise in any modelling of optimal bankruptcy rules may lead to a suboptimal design. We also find that the amount of noise in this market appears to have declined over time as more institutional/informed investors have entered the market for bankrupt firms' securities and the effect of change in the bankruptcy law has become clearer, both consistent with the noisy rational expectations hypothesis.     

Estimating liquidity premia in the Spanish government securities market

This paper investigates the presence of liquidity premia in the relative pricing of assets traded on the Spanish government securities market. First, a classification of bonds into four different categories based on their degree of liquidity is proposed. Second, liquidity premia are estimated introducing liquidity parameters in the estimation of the zero-coupon yield curve. Results suggest the existence of a liquidity premium for post-benchmark bonds (both strippable and non-strippable). The size of this premium is relatively small. In the case of pre-benchmark bonds, the lack of liquidity does not seem to be priced. It is also shown that these pricing discrepancies are robust to the impact of taxes on bonds.     

Single-stock futures: Evidence from the Indian securities market

Although single-stock futures (SSFs) are useful multi-purpose stock derivatives, they have not received much attention in developed markets. We analyze SSFs in the Indian market to understand their contribution in price leadership. The findings indicate that trades in the stock market contribute more to price discovery than trades in the SSF market (72% and 28%, respectively), while quotes in the SSF market are more price innovative than quotes in the stock market (39% and 61%, respectively). Our analysis suggests that while stock and SSF trade returns have predictive ability for each other, in the case of quotes, only SSF quotes have predictive ability for stock and SSF returns.     

Auction failures and the market for auction rate securities

The market for auction rate securities (ARS) made headlines during the second week of February 2008 when auctions at which the bonds’ interest rates reset experienced a wave of “failures.” Contrary to headlines that attribute the failures to a “frozen” market or investors’ “irrationality,” we find that (1) even at their height, less than 50% of ARS experienced auction failures, (2) the likelihood of auction failure was directly related to the level of the bonds’ “maximum auction rates,” (3) the implied market clearing yields of bonds with failed auctions were significantly above their maximum auction rates, and (4) ARS yields were generally higher than yields of various cash equivalent investment alternatives. We infer that investors priced the possibility of auctions failures into ARS yields and rationally declined to bid for bonds for which required market yields exceeded their maximum auction rates.     

证券市场信息披露中注册会计师的法律责任

当前弥漫我国证券市场的虚假信息强烈冲击着注册会计师行业的可信度和社会地位,广大投资者通过起诉注册会计师来保护自身利益成为一种趋势,而注册会计师法律责任问题也对现行相关法律法规提出了新的挑战.本文集中讨论了虚假报告界定的法律标准、民事责任性质、归责原则及举证责任设置、虚假报告的鉴定制度等部分问题,并提出了对虚假报告的鉴定可以考虑建立独立的审计鉴定人名册制度和具体案件的鉴定人随机选任制度.     

The impact of the French securities transaction tax on market liquidity and volatility

In this paper, we assess the impact of the securities transaction tax (STT) introduced in France in 2012 on market liquidity and volatility. To identify causality, we rely on a distinctive design of the tax, which is imposed on large French firms only, all listed on Euronext. This provides two reliable control groups (smaller French firms and foreign firms listed on Euronext) and allows us to use a difference-in-difference approach in order to isolate the impact of the tax from the other economic changes that have occurred simultaneously. We find that the STT has reduced stock trading, but we find no significant effect on theoretically based measures of liquidity, such as price impact, and no significant effect on volatility. The results are robust whether we rely on different control groups (German stocks listed on the Deutsche Börse), different datasets (firm-level or aggregated data), different periods (from one to six months), or different methodologies (propensity score matching, regression discontinuity design).     

The impact of naked short selling on the securities lending and equity market

This paper examines the impact of naked short selling on equity markets where it is restricted to securities on an approved list. Consistent with Miller's (1977) intuition, stocks with the highest dispersion of opinions and short sale constraints are the only stocks to exhibit significant and negative abnormal returns in the post-event period. We also find slightly higher stock return volatility and a small reduction in liquidity when naked short sales are allowed. Overall, it impairs market quality (liquidity and volatility), although there appears to be some improvement in price efficiency in stocks with high short sale constraints.     

Dealer behavior in the specials market for US Treasury securities

We assess dealer behavior in the specials market for US Treasury securities by comparing dealer participation in the Federal Reserve's securities loan auctions with prices in the private market. Dealer behavior is generally consistent with the law of one price and apparent violations can largely be explained by institutional differences between the private market and the Fed's program. However, for auctions that are effectively noncompetitive, dealers regularly pass up true arbitrage opportunities and frequently overpay to borrow securities. Dealers apparently do not realize that certain auctions are noncompetitive, even though the information needed to discern this fact is publicly available in advance.
