The Stock Market Valuation of Research and Development Expenditures

We examine whether stock prices fully value firms' intangible assets, specifically research and development (R&D). Under current U.S. accounting standards, financial statements do not report intangible assets and R&D spending is expensed. Nonetheless, the average historical stock returns of firms doing R&D matches the returns of firms without R&D. However, the market is apparently too pessimistic about beaten-down R&D-intensive technology stocks' prospects. Companies with high R&D to equity market value (which tend to have poor past returns) earn large excess returns. A similar relation exists between advertising and stock returns. R&D intensity is positively associated with return volatility.     

中国证券市场分析师推荐投资价值研究

本文采用中国A股市场中四个主要的证券分析机构在2006年1月1日到2007年4月1日间所发布的股票评级调整事件作为样本，用事件研究法证明了中国A股市场中证券分析机构提供的评级调整推荐报告对股票价格具有显著的影响，而且这种影响还持续了相当长的一段时间。不同研究机构影响力的差异能够在短时间内产生显著的异常收益，但在长的时间段内则效应不显著。不同分析师连续多次调整评级不是主要的影响因素，并没有产生异常收益的显著差异。

Stock Market Valuation,Foreign Investment,and Cross-Country Arbitrage

This study investigates the role of stock market valuation and cross-country arbitrage in shaping foreign direct and indirect investments, contingent upon a country's stage of development. This paper is built upon the mispricing-driven foreign investment hypotheses developed by Baker, Foley, and Wurgler (2009). Interesting findings emerge when developed and emerging markets are considered separately. Empirical evidence indicates that the use of relatively cheap financial capital for foreign investment is prominent among developed countries, but not so in emerging markets. This is largely due to the extremely low level of foreign investment outflows in emerging markets and the inability of unsophisticated emerging market managers to successfully time the market. Further investigation shows that host-country stock market valuation is an important determinant of the mode of foreign investment; investors tend to choose indirect or portfolio investment, as opposed to direct investment, when the stock market is perceived to be undervalued. This is especially the case in emerging markets, where there is more room for misvaluation and potential arbitrage. These findings suggest that the unique institutional features of the markets involved play an important role in shaping foreign investment and cross-country arbitrage.     

The Degree of Internationalization and the Stock Market Valuation of Earnings

In this paper, we examine the impact of the degree of internationalization on a firm's ability to reduce risk and increase profits. Our study seeks to overcome three limitations of many previous studies on the value of internationalization: use of a single measure of internationalization, accrual-basis accounting measures of firm performance, and a small sample size. We use a multi-measure index, stock market assessment, and a large sample size of various firms. Our findings indicate that (1) a firm's degree of internationalization has a positive impact on the investor response to the earnings changes and (2) the market's positive response to the value of internationalization is confined to a high level of internationalization. Our results do not support the argument that, at high levels of internationalization, the costs of internationalization exceed the benefits.     

Valuation and Optimal Exercise of the Wild Card Option in the Treasury Bond Futures Market

The Chicago Board of Trade Treasury Bond Futures Contract allows the short position several delivery options as to when and with which bond the contract will be settled. The timing option allows the short position to choose any business day in the delivery month to make delivery. In addition, the contract settlement price is locked in at 2:00 p .m . when the futures market closes, despite the facts that the short position need not declare an intent to settle the contract until 8:00 p .m . and that trading in Treasury bonds can occur all day in dealer markets. If bond prices change significantly between 2:00 and 8:00 p .m ., the short has the option of settling the contract at a favorable 2:00 p .m . price. This phenomenon, which recurs on every trading day of the delivery month, creates a sequence of 6-hour put options for the short position which has been dubbed the “wild card option.” This paper presents a valuation model for the wild card option and computes estimates of the value of that option, as well as rules for its optimal exercise.     

中国股市新股发行内在价值模型的选择

基于中国资本市场的特殊制度背景,研究中国股市泡沫的着眼点应当是新股发行全过程,即新股从定价、发行至上市的完整过程。IPO泡沫是股市泡沫的重要组成部分,但是研究IPO泡沫的核心问题是IPO估值方法的选择。本文通过剩余收益法和股权自由现金流量法对IPO样本公司进行估值,从理论和估值结果两个方面分别进行分析比较,发现剩余收益法比自由现金流量折现法更适合于中国股市IPO估值。

提高存款准备金率对国债市场影响的实证分析

本文使用干预分析模型，研究了2004年4月25日央行上调存款准备金率这一干预事件对我国国债市场的影响。文中将干预事件的发生时刻设定为政策公布日2004年4月12日。研究结果显示，上调存款准备金率政策公布后，负面影响逐渐上升。4月29日负面影响累计达到最大，此时交易所国债指数也跌到最低点。中国的国债市场仍然尚未达到半强势有效市场。     

国债收益率对信贷市场均衡的影响

国债市场规模的扩大可以满足机构投资者的收益性和流动性偏好,机构投资者投资组合的调整使得国债具有影响信贷市场均衡的功效:国债收益率变化影响信贷市场利率和信贷市场均衡规模。实证研究表明,在协整关系上国债收益率和信贷资金增长率具有负相关关系,表明国债收益率上升对信贷资金增长率具有降低作用,不过效果不明显,不足以成为影响信贷市场资金规模的原因。国债收益率和信贷资金增长率不互为因果关系,这与中国国债规模偏小、持有者结构不合理和交易所国债市场逐渐边缘化的趋向有关。     

New Issue Yield Spreads in the 30-Year Treasury Bond Market

This paper investigates the seasoning process of yield spreads between newly issued and seasoned 30-year Treasury bonds. These securities provide a unique data set for analyzing this relationship in that they allow for control of noncoupon differences between securities that were present in previous studies on corporate bonds. The results indicate that, in contrast to the existing literature, there appears to be a price premium for newly issued securities. We attribute this difference primarily to be a function of a higher degree of liquidity inherent to newly issued Treasury bonds.

中期和长期国债收益率的非线性协和关系及动态调整

本文分析探讨一种用于揭示非平稳时间序列非线性调整过程的模型——两机制门限协和模型,深入研究了该模型的参数估计、检验统计量,并通过自助法模拟计算其检验统计量临界值及P值。鉴于我国中期和长期国债收益率之间存在协和关系,但由于经济主体调整行为的不连续性,这种协和关系往往表现为非线性调整过程,利用传统线性向量误差修正模型无法揭示这种调整过程。为此,本文利用两机制门限协和模型研究我国的中期和长期国债收益率的非线性调整过程,研究结果表明:我国中期和长期国债收益率存在门限非线性协和关系,并可用该模型验证期限结构理论。     

The Stock Market and Corporate Investment: A Test of Catering Theory

We test a catering theory describing how stock market mispricingmight influence individual firms' investment decisions. We usediscretionary accruals as our proxy for mispricing. We finda positive relation between abnormal investment and discretionaryaccruals; that abnormal investment is more sensitive to discretionaryaccruals for firms with higher R&D intensity (opaque firms)or share turnover (firms with shorter shareholder horizons);that firms with high abnormal investment subsequently have lowstock returns; and that the larger the relative price premium,the stronger the abnormal return predictability. We show thatpatterns in abnormal returns are stronger for firms with higherR&D intensity or share turnover.     

Stock Market Valuation of Deferred Tax Assets: Evidence from Internet Firms

Abstract:   We use the provisions of SFAS No. 109 , Accounting for Income Taxes , to examine the extent to which stock prices of Internet firms were associated with expectations of future profitability before versus after the 'market correction' in early 2000. We find that the valuation of deferred tax assets of firms with business models reliant on the level of web site traffic was significantly greater after the market correction. In our view, this evidence is consistent with pre‐correction mispricing.
