French and U.S. trading of cross-listed stocks around the period of U.S. decimalization: Volume, spreads, and depth effects

We analyze how U.S. decimalization affects stocks cross-listed in France (Euronext) and the U.S. (NYSE). The French stocks examined are much larger than the non-U.S. stocks examined in prior studies of decimalization, and their U.S. trading is likely to be dominated by institutions. So, we explore whether a reduction in depths in the U.S. due to decimalization makes the U.S. market less competitive for institutions trading these French stocks. We find evidence consistent with the above. First, the average NYSE trade size for these stocks relative to that on Euronext declines substantially after decimalization. Second, we categorize individual trades by the number of shares traded. We find that mainly driven by large trades, the NYSE proportion of trading of French firms declines markedly after decimalization. Third, using regression analysis, we find that the decline in the U.S. share of institutional trading volume is significantly positively related with the decline in NYSE depths relative to Euronext, and the decline is greater for French firms. Overall, we find consistent results indicating a migration of institutional order flow in French firms to France after NYSE decimalization. Also, intraday analysis indicates that the institutional volume in both France and the U.S. is greatest when both the markets are open.     

全球金融动荡下的中国股票市场及政策选择

中国股票市场自2007年10月以来的深度调整在全球金融动荡的背案下有加速之势、当欧美主要国家频频推出救市举措之际，要求中国政府进行救市的言论再次兴起。文章分析了中国股票市场持续下行的根源以及政府救市的困境、在全球金融市场动荡以及国内市场仍然高估的情况下，直接的救市措施并不可行，还可能产生严重的政策风险和经济风险，不利于中国股市的发展，救市不如救经济。     

Air transportation and urban-economic restructuring: competitive advantage in the US Carolinas

The theoretical agenda of this paper is to bring airports and airline operations more squarely into the mainstream of the urban and regional development literature. The paper examines the spatial and temporal patterns of air passenger flows by airport in the US Carolinas. An emphasis is placed on articulating the linkages that exist between airport operations at the local level, the structural composition of the regional economy, and the competitive strategies of the airline industry. Particular attention was paid to administrative and auxiliary employment levels because it is a knowledge-based producer service that tends to seek out markets that offer high levels of air service connectivity to other places. A major finding in this paper is that those US Carolina airports that experienced significant gains in air passenger volume (e.g., Charlotte and Raleigh-Durham) tended to experience comparable gains in the employment levels of administrative and auxiliary workers, particularly in the manufacturing sector.     

A NUCLEAR FUTURE? UK GOVERNMENT POLICY AND THE ROLE OF THE MARKET

Nuclear power should be a feasible non‐carbon option in a liberalised market for electricity generation. However, if it is to be so, there needs to be a stable carbon price and a tax system which does not treat nuclear generation in a similar way to carbon‐based electricity generation. Further major reform of the electricity generating market will also be necessary.     

Capital flows,current account deficits,and financial crises in emerging market economies

Some emerging market economies are said to face today conditions similar to those faced by Mexico in 1994 at the time of its serious financial crisis. This paper identifies a number of macroeconomic and financial indicators, constructs a profile of the Mexican economy at the time of the crisis, and then compares these with the conditions in other major emerging market economies in Latin America and Asia today in order to determine the extent to which they resemble those of Mexico at the time of the 1994 crisis. The conclusion is reached that macroeconomic and financial indicators cannot by themselves predict Mexican-style financial crises. In today's world of highly integrated capital markets, any anticipation of financial unsustainability can lead to a massive capital outflow from the nation and trigger a crisis, with the catalyst usually being a worsening political problem. The usefulness of the indicators discussed is in providing a profile of the financial condition of the nation, evaluating the potential danger of a financial crisis, anticipating the depth of the crisis if one arises, and pointing to the precautions that a nation can take in trying to avoid a crisis or reduce its severity if one does occur.     

The modified mixture of distributions model: a revisit

Andersen (J Financ 51, 169–204 (1996)) introduced a modification of the mixture of distributions model based on microstructure arguments. Based on a small sample of five stocks, he infers that this modified mixture of distributions (MMD) model adequately captures the joint behavior of trading volume and volatility. We re-examine this claim using a larger sample of twenty-two stocks and two sample periods. Our tests show that 59% of the sample rejects the MMD model in the period 1973–1991, the same period studied by Andersen. Results for the second period (1993–1999) are more supportive of the MMD, especially for number of trades, although nearly one-third of the sample still rejects the MMD. We conclude that further tests are needed before the general validity of the MMD can be established. JEL Classification Numbers C12, C52     

Informed trading before analyst downgrades: Evidence from short sellers

This paper studies short-selling prior to the release of analyst downgrades in a sample of 670 downgrades of Nasdaq stocks between 2000 and 2001. We find abnormal levels of short-selling in the three days before downgrades are publicly announced. Further, we show that this pre-announcement abnormal short-selling is significantly related to the subsequent share price reaction to the downgrade, and especially so for downgrades that prompt the most substantial price declines. Our findings are robust to various controls that might also affect short-selling such as pre-announcement momentum, three-day pre-announcement returns, and announcement-day share price. In addition, the results are independent of scheduled earnings announcements, analyst herding, and non-routine events near downgrades. Further evidence suggests that tipping is more consistent with the data than the prediction explanation which posits that short sellers successfully predict downgrades on the basis of public information about firms’ financial health. Finally, we present evidence that downgraded stocks with high abnormal short-selling perform poorly over the subsequent six months by comparison with those with low abnormal short-selling. Overall, our results support the hypothesis that short sellers are informed traders and exploit profitable opportunities provided by downgrade announcements.

投资者税负差异、税率变动与除息日股价行为——来自A/B股公司的证据

自Campbell 和 Beranek （1955）以来，除息日股价行为之谜一直是困扰学术界的经典难题。半个世纪中，税收效应假说和短期交易假说在解释除息日股价为方面各有建树，但也均遭到经验数据的不支持。中国既发行A股也发行B股的86家公司，在税收上存在的横向差异与纵向变动为求解除息日股价为之谜提供了一个分很好的实验环境。本文经验研究结果表明，除息日股价行为不能用短期交易假说解释，股票市场除息日股价行为一定程度上是股息税与资本利得税之间的差异造成的。
