The Role of Book Income, Web Traffic, and Supply and Demand in the Pricing of U.S. Internet Stocks

In this paper I assess the degree of similarity in the cross-sectionalpricing of Internet and non-Internet stocks during the tumultuousyear of 2000. Despite large differences in their economic fundamentals, I find that the equity market values of Internetfirms with immaterial web traffic, firms that are randomly selected, and firms that went public atthe same time as Internet firms are similarly related to analysts' forecasts of earnings in 2001 andthe long-term rate of growth in earnings. This is not the case for firms with intensive web traffic.I also find that at the peak of Internet prices in March 2000 the market rewarded losses ofweb-traffic-intensive firms but did not reward profits, while after the peak the market reversed itsview, rewarding profits but not losses. Beyond earnings, web traffic is significantly positivelypriced both at and after the Internet peak. However, I find no evidence that two proxies forsupply and demand forces – the degree of public float and short interest – are value-relevantfor Internet firms. Overall, I argue that there are enough similarities in the cross-sectional pricingof Internet and non-Internet firms to make it unlikely that the pricing of Internet stocks during2000 was entirely irrational. Moreover, any irrationality in the prices of Internet stockscannot be linked to public float and short interest.     

International trade and world food security : The role of developed countries since the World Food Conference

No mechanism is in place for the international coordination of grain stocks. World market stability is largely dependent upon the actions of major grain trading countries. These countries have avoided the exportation of their domestic supply variations onto world markets over the past decade, but have been reluctant to allow domestic consumption to respond to world shortages and surpluses. Improvement in the sensitivity of domestic storage and consumption to world conditions could increase their contribution to world food security.     

关于我国股票市场发展的若干思考

虽然我国股票市场的发展已经走过了10多年的历程,但是相对于发达国家的股票市场而言,我国股票市场目前尚处于起步阶段。因此,从股票市场发展的长期趋势来讲,稳定是压倒一切的大局,没有稳定的股票市场不可能取得长足的发展;中国股票市场的发展应该定位于为所有的内含于社会主义市场经济内部的企业服务,而不应该把股票市场看作是国有企业的"专利品";从规范股票市场的角度讲,应分期分批的实现国家股和法人股的流通。     

Analyst Activity and Firm Value: Evidence from the REIT Sector

This paper is the first to examine (1) properties of analyst forecasts and (2) effects of analyst following on firm value for all REITs on CRSP, Compustat and I/B/E/S. Our results suggest that REITs operate in an information environment that has changed over time. We find that for periods when the REIT industry was either in the developmental stage (pre-1992), or after other structural changes in the industry (post-2000), more analysts cover REITs and forecasts are more accurate and less biased. Further, we find that mortgage REITs are more transparent than other REIT structures and exhibit properties of analyst behavior that are different from other types of REITs. Our investigation into the effect of analyst coverage on REIT value suggests that analyst coverage increases REIT value (as measured by Tobin’s q) and that the causality does not run the opposite way.

REITs,Decimalization, and Ex-dividend Stock Prices

The ex-dividend pricing of real estate investment trust (REIT) stocks under fractional and decimal pricing regimes is investigated. For REITs, with the move from discrete to decimal pricing, the price drop on the ex-dividend day approaches the dividend amount, the ex-date abnormal return decreases, the spread-to-dividend ratio declines, abnormal trading volume increases, and the potential erroneous appearance of a tax-clientele effect is diminished. Discreteness and other transaction costs are reduced with decimalization implying that part of the persistence in the appearance of the tax-clientele effect when modeling ex-dividend stock pricing might be generated by the interaction between transaction costs, dividend amount, and yield.      

US shipping initial public offerings: Do prospectus and market information matter?

This paper examines the extent that public information, available prior to the initial public offering of shipping companies, is only partially incorporated in the final offer price. The sample includes shipping US initial public offerings that took place in the period 1987-2008, and the analysis employs a set of IPO, market, and firm specific characteristics. Our findings have both theoretical and empirical implications for shipping IPOs, and indicate that there is no asymmetry of information between participants in shipping IPOs. On the theoretical part, the partial adjustment theory of Benveniste and Spindt (1989) is supported, whereas the winner’s curse theory of Rock (1986) is rejected. On the empirical side, the probability of underpricing can be predicted by employing variables available to all IPO participants prior to the issue.

The tail risk of emerging stock markets

We investigate tail risk in emerging stock markets at the country, regional and world levels, by comparing the investable and non-investable segments in terms of the expected shortfall of standardized returns and tail dependence on the world market. Employing the skewed Student-t GJR-GARCH model and the SJC copula, we show that most investable portfolios have lower tail risk but higher tail dependence than non-investable ones; emerging markets are likely more dependent on the world market during large joint losses than large joint gains; and tail dependence of the aggregate and investable markets on the world market varies across countries and regions.

How do employee training and knowledge stocks affect product innovation?

The main purpose of this paper is to explore how interactions of knowledge flows and knowledge stocks could shape firms’ innovative performance. Knowledge flows are measured on the grounds of human resource training practices while different levels and forms of knowledge stocks (i.e. educational attainment, exporting activity, and firm age) are considered. We make use of two-period panel probit regressions and a rich data survey of the 524 largest Greek manufacturing firms conducted in two waves (2011 and 2013). Our findings suggest that the beneficial effects of knowledge flows strengthen when knowledge stocks accumulated by employees’ education and firm age are low. When knowledge stocks are limited, knowledge flows can act as a bridge for product innovation. On the contrary, when knowledge stocks are high, higher investments in knowledge flows may lead to diminishing returns and, thus, to decreased innovation performance beyond a certain point.
