我国股票市场的财富效应分析

股市可以形成一定的虚拟财富效应,对刺激有效需求能产生正效应。而股市的实际财富效应取决于股市行情上涨对企业投资的传导,这一点又受制于股票市场规模、股市上涨持续的时间以及市场的有效性。     

艾略特波浪理论的一种新解说--兼论中国股市的季节波动

中国股市是否存在艾略特波浪?利用统计方法对艾略特波浪理论在中国股市的表现进行实证分析时发现,中国股市存在显著的季节性波动,且这种季节波动和艾略特波浪有着惊人的相似之处,完全可以将季节波动看作艾略特波浪的一种表现形式。上述研究成果同时也证明了艾略特波浪理论在中国股市的客观存在。     

我国证券市场税收政策浅析

我国现行以证券交易印花税为主体的证券税制,在组织财政收入、调节证券市场、抑制过度投机等方面发挥了一定作用,但还存在一些不足之处。建议:进一步调整证券交易印花税的征收办法;建立一套系统、健全的证券税制;消除对公司和股东个人股、红利的重复征税;统一上市公司的企业所得税政策。     

中国股票市场政策演进:公共选择视角

我国中央政府在股票市场中存在双重利益目标:国有企业筹资和资金使用效益最大化,且前者优先。基于此,中央政府对股票市场做出了初始政策安排。但在政策运行中,地方政府、上市公司、市场中介、投资者等经济主体出于各自利益目标,采取了不同行动策略,从而降低了资金使用效益,减少了国有企业筹资额,使得股票市场初始政策安排的收益不断“缩水”。     

Stock Prices and Inflation: New Evidence from the Pacific-Basin Countries

This paper investigates the statistical relationship between stock prices and inflation in nine countries in the Pacific-Basin. On balance, regression analysis on the nine markets shows negative relationships between stock returns in real terms and inflation in the short run, while co-integration tests on the same markets display a positive relationship between the same variables over the long run. The time path of the response of stock prices plotted against corresponding changes in consumer price indices validates this dichotomy in time-related response patterns of stock prices to inflation; namely, a blip of negative responses at the beginning changes to a positive response over a longer period of time. Stock prices in Asia, like those in the U.S. and Europe, appear to reflect a time-varying memory associated with inflation shocks that make stock portfolios a reasonably good hedge against inflation in the long run.     

Time-varying moments, idiosyncratic risk, and an application to hot-issue IPO aftermarket returns

This paper proposes time-varying idiosyncratic risk as a component driving conditional abnormal returns and outlines a corresponding Engle et al. [Econometrica 55 (1987) 391] ARCH-M market model. An application is given to initial public offering (IPO) aftermarket stock returns, where a positive relation between idiosyncratic risk and returns is consistent with young issues’ equity as a contingent claim on firm assets. The empirical results for an illustrative sample of German Neuer Markt stocks traded during the first two years after initial listing indicate pronounced skewness as well as a positive relation between conditional idiosyncratic risk and expected returns. Conditioning aftermarket performance on risk yields much lower levels of abnormal return significance than a standard approach.     

Microstructure and reverse stock splits

In this paper we show that, similar to NYSE/AMEX stocks, NASDAQ stocks exhibit significant ex date returns for reverse stock splits. Although the 10-day cumulative return after the ex date is close to –10%, this does not violate market efficiency, because the average bid-ask spread for the reverse split stock is at least double this return. We also document that these large negative returns are mostly due to a drop in the ask price while bid prices barely change at all. Furthermore, the ex date returns are negatively related to trading volume.These results suggest that there is abnormal selling and a significant buildup of market makers' inventories near the ex date. To reduce the inventory buildup, market makers lower ask prices to induce buying by investors, resulting in the observed negative returns. Lowering bid prices, an alternative strategy for reducing inventories, is not attractive to market makers due to competitive factors and the reduction of commissions associated with a smaller number of transactions. Notably, selling investors have no incentives to sell their stocks early to avoid the observed negative ex date return, since this return is largely an ask price phenomenon and does not represent realized returns to sellers.     

证券市场的货币政策传导功能实证研究

货币政策是货币当局对经济进行宏观调控的重要工具，政策的有效性首先取决于金融领域的传导机制。长期以来我国的货币政策一直以银行信贷为主要传导枢纽，但随着资本市场的发展，其传导功能将日益强化。本文通过实证分析，建议实施货币政策时应充分考虑资本市场对货币政策传导功能的影响。
