The estimation of physical intensity processes in the context of default risk is investigated here. Using data from Moody's Corporate Bond Default Database, a term structure of default probabilities for different rating classes is constructed each year from 1970 to 2001. Two specifications used for modeling the dynamics of the (risk‐neutral) intensity process in the bond‐pricing literature are then examined empirically: the Ornstein–Uhlenbeck and square‐root cases. The results reveal that the Ornstein–Uhlenbeck case is not an adequate modeling alternative with a rejection of this specification in five out of seven credit classes and nonsignificant mean reverting behavior for all credit classes. The square‐root case obtains better results with four credit classes out of seven for which this specification cannot be rejected and significant mean reversion parameters in many cases. © 2008 Wiley Periodicals, Inc.

This study examines the competition in price discovery among stock index, index futures, and index options in Taiwan. The price‐discovery ability of the Taiwan Top 50 Tracker Fund, an exchange‐traded fund based on the Taiwan 50 index is examined. The authors find that, after the minimum tick size in the stock market decreases, the bid–ask spreads of the component stocks of the stock index and the Taiwan Top 50 Tracker Fund get lower, and the contribution of the spot market to price discovery increases. © 2008 Wiley Periodicals, Inc.

(1252) Tegegne Gebre‐Egziabher This paper examines the developmental impact of China and India on Ethiopia by examining macro‐level trade, investment and aid relation, and micro‐level impacts on local micro and small‐scale footwear producers. Both secondary and primary data were used. At macro level there are clear evidences of an increase in trade between Ethiopia on the one hand and China and India on the other, though the trade balance disfavours Ethiopia. China has displaced other countries as export destinations for Ethiopia. Similarly, the presence of China and India is also felt in the areas of investment and aid. At local level, Chinese imports of footwear have forced local enterprises to downsize their activity and lose assets and money. At the same time, however, firms have followed both the high road of competition (design and quality improvement, investment in machinery, product specialisation) and the low road of competition (lowering price and profit, reducing raw materials and inputs, and joining the informal sector) to withstand the impact of Chinese imports. The long‐term effect of Chinese imports is to crowd out local efforts of using the sector as the basis for industrialisation. Government, non‐government organisations and local producers should work together in order to withstand the negative impacts of footwear imports by raising the competitiveness of the local producers. 相似文献

Strategic order splitting,order choice,and aggressiveness: Evidence from the Taiwan futures exchange
We investigate the strategic order‐splitting behavior and order aggressiveness of different types of traders using a unique dataset on the Taiwan Futures Exchange. By examining the trades and orders for each and every account, we find that, as compared with domestic institutional traders and individual traders, foreign institutional traders and futures proprietary firms are more likely to split their orders and it appears that the price adjustments after their trades are permanent. Foreign institutional traders and futures proprietary firms seem to be better informed, with their orders apparently being split so as to reveal their information on a gradual basis. Furthermore, we find that foreign institutional traders and futures proprietary firms use fewer market orders, choosing instead to submit aggressive limit orders, possibly due to their desire to make the most of their information advantage. © 2009 Wiley Periodicals, Inc.

This paper investigates the relationships between basic needs and economic growth where the interactions between output, health, nutrition and education are explicitly simultaneous. We find a unidirectional relationship that improving basic welfare contributes strongly to labour productivity change, but a clear reverse causation only from growth to nutrition. There are substantial differences in the patterns of simultaneous interactions at different income and welfare levels. There are strong self‐reinforcing effects of literacy and debt service on poverty, making it difficult for poor countries to rectify their situation. Channelling resources towards improving health, education and nutrition could bring dramatic economic returns. 相似文献

Substantial progress has been made in developing more realistic option pricing models for S&P 500 index (SPX) options. Empirically, however, it is not known whether and by how much each generalization of SPX price dynamics improves VIX option pricing. This article fills this gap by first deriving a VIX option model that reconciles the most general price processes of the SPX in the literature. The relative empirical performance of several models of distinct interest is examined. Our results show that state‐dependent price jumps and volatility jumps are important for pricing VIX options. © 2009 Wiley Periodicals, Inc. Jrl Fut Mark 29:523–543, 2009 相似文献

An examination of consumers’ cross-shopping behaviour 总被引:1,自引:0,他引:1

This study addresses antecedents of cross-shopping behaviour. Five theory-driven hypotheses are derived and tested. The results indicate that impulse buying tendency and perceived time pressure have a statistically significant negative effect on supermarket patronage. Product assortment and price consciousness have a statistically significant negative effect on speciality store patronage, while impulse buying tendency and convenience orientation have a statistically significant positive effect on speciality store patronage. Perceived time pressure has a statistically significant positive effect on meat store patronage. This effect is, however, not statistically significant on seafood store patronage. The findings have managerial implications for both supermarkets and speciality stores. 相似文献

For years, countries in the Middle East and North Africa (MENA) region have been trying to increase entrepreneurship rates and attract foreign investment, however, their bankruptcy statutes remained antiquated and punitive in nature. Potential start‐ups and foreign investors have been deterred from these markets due to a lack of alternative solutions to liquidation and a fear of punishment for business failure. At least seven countries in the region have now taken steps to modernize their bankruptcy laws to provide restructuring mechanisms and other measures designed to incentivize risk‐taking rather than to deter it. With this year's crash in oil prices, an unprecedented global pandemic and an imminent recession, an effective bankruptcy system has become even more critical to avoid catastrophic results for the employment rates and economic value of the companies in the region. However, despite these recent reforms, significant improvements are still needed to maximize the value and benefits of bankruptcy procedures in the face of these growing economic threats. 相似文献
