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

This article investigates two factors posited to affect consumers' ability to learn a novel attribute relationship (e.g., “no pesticides → USDA organic symbol”) and apply this recently acquired knowledge when making judgments in a new product category. The first factor concerns the nature of the attribute encoding process and, in particular, whether it allows for comparison of examples. The second factor focuses on the relationship between the learning and transfer domains, and examines the influence of perceptual similarity (manipulated two ways: similarity in the elements comprising the attribute relationships, and similarity between the base and target domains) on the transfer process. Study 1 revealed a significant improvement in inter‐domain transfer when a relationship was learned in a multiple‐domain/multiple‐attribute learning environment over a single‐domain/single‐attribute environment. When attribute and domain diversity were examined separately (Study 2), it was found that attribute, but not domain, diversity produced the greatest improvements in transfer. Study 3 showed that the benefits of adding a perceptual similarity cue were most apparent when the transfer conditions were neither too easy (within domain and within attribute) nor too difficult (inter‐domain and inter‐attribute). © 2009 Wiley Periodicals, Inc. 相似文献

In expanding their market to the global level with clear and consistent global brand images across nations, marketers are ever confronting the issue of how to deal with different cultural values. Cultural value is identified as an influential factor on brand image and is widely accepted as one of the crucial concepts in understanding consumer consumption value, which determines choices of consuming everyday products and services. Most firms endeavoring to establish and maintain consistent global brand images, however, adopt a standardized brand image strategy that usually does not consider individual target markets” characteristics, including the concepts of cultural value and consumption value. This study developed a conceptual framework which incorporated cultural value not only as a direct antecedent of brand image, but also as an indirect antecedent of brand image through consumption value, and empirically tested it using the category of apparel. Following this framework, this study hypothesized the differences in brand image, cultural value, and consumption value between the U.S. and South Korea. Data were gathered through surveying university students residing in the San Francisco and Seoul metropolitan areas using a convenience sampling method. A total of 329 completed questionnaires were used in factor analysis, discriminant analysis, and structural equation modeling. The results provide insights into standardized brand image strategies and suggest some implementable tools that might prove effective in both countries. © 2009 Wiley Periodicals, Inc. 相似文献

Two studies investigated whether various tactics of personal selling that generate different levels of resistance also produce different degrees of third‐person perceptions. Furthermore, the studies compared third‐person perceptions to the actual influence on behavior. Study 1 showed that more direct and blatant selling methods produce more TPP. Study 2 showed that people tend to underestimate the influence of the more direct method, especially with regard to themselves. The study concludes by identifying the ideal selling method as one in which the customers are asked about their willingness to listen to the sales campaign before they are told about it. This method increases sales and creates satisfied customers. © 2009 Wiley Periodicals, Inc. 相似文献
