The price adjustment and lead-lag relations between stock returns: microstructure evidence from the Taiwan stock market

This paper investigates the price adjustment and lead-lag relations between returns on five size-based portfolios in the Taiwan stock market. It finds evidence that the price adjustment of small-stock portfolios is not slower than that of large-stock portfolios. Additionally, limited evidence supports a positive leading role of large-stock portfolio returns over small-stock portfolio returns. These two findings are substantially different from the results of previous research on developed markets.

UNIT MANAGEMENT BUYOUTS, STOCKHOLDER WEALTH, AND SELLING FIRMS' CHARACTERISTICS

Previous research on unit management buyouts, UMBs, has shown that selling firms benefit from the selloff transaction. The current research demonstrates that when the selling firm has either poor liquidity or poor earnings, selling firm shareholders do not benefit as much. We hypothesize that the unit managers have knowledge about the selling firm's difficulties so they do not pay as large a premium for the assets. Since the unit managers technically are employed by the selling firm shareholders, their bargaining to achieve a better price is an agency cost. Finally, selloff frequency does not affect seller abnormal returns.

An empirical analysis of the relationship between the hedge ratio and hedging horizon: A simultaneous estimation of the short‐ and long‐run hedge ratios

This article analyzes the effects of the length of hedging horizon on the optimal hedge ratio and hedging effectiveness using 9 different hedging horizons and 25 different commodities. We discuss the concept of short‐ and long‐run hedge ratios and propose a technique to simultaneously estimate them. The empirical results indicate that the short‐run hedge ratios are significantly less than 1 and increase with the length of hedging horizon. We also find that hedging effectiveness increases with the length of hedging horizon. However, the long‐run hedge ratio is found to be close to the naïve hedge ratio of unity. This implies that, if the hedging horizon is long, then the naïve hedge ratio is close to the optimum hedge ratio. © 2004 Wiley Periodicals, Inc. Jrl Fut Mark 24:359–386, 2004

来自美国能源公司的观点:如何看待能源供应安全

实行石油供应来源多样化有利于提高石油供应的安全性，但是要使供应多样化有效地发挥作用，关键要分清哪些是商业石油供应国，哪些是战略石油供应国。确定前者的重要且充分条件是其石油供应的规模和增长潜力，而后者必须有较大的机动生产能力来弥补世界其他地区的供应中断。据此分析，沙特阿拉伯仍将是可靠的战略石油供应国，伊拉克不会成为新的机动产油国，俄罗斯的石油也不能作为能源安全的基础，里海地区仍有诸多风险，西非对世界石油供应格局的影响有限，拉丁美洲则需要扩大油气部门的开放。对美国而言，最为紧迫的能源安全问题不是石油供应安全而是天然气供应安全。天然气尚未成为全球性商品，难以长途运输且船运费用高昂。美国国内天然气供应和价格所面临的压力对美国的能源安全和经济产生的威胁要大于原油成本的上升。
