ASYMPTOTICS OF IMPLIED VOLATILITY IN LOCAL VOLATILITY MODELS

Using an expansion of the transition density function of a one‐dimensional time inhomogeneous diffusion, we obtain the first‐ and second‐order terms in the short time asymptotics of European call option prices. The method described can be generalized to any order. We then use these option prices approximations to calculate the first‐ and second‐order deviation of the implied volatility from its leading value and obtain approximations which we numerically demonstrate to be highly accurate.     

The political economy of defense procurement and acquisition: The case of South Korean ministry of defense

South Korea faces growing problems in the area of productivity and competitiveness throughout its economy. These problems are also present in the economies of the armed forces. The purpose of this paper is to present methods of improving the productivity of the South Korean Ministry of Defense's acquisition and procurement processes. It also attempts to mention the South Korean defense environment including defense industry after the Second World War, to point out the problems of Korean Fighter Program (KFP) as a case study, to explain concepts and principles of Total Quality Management, which is a management philosophy and methods, and to provide with the possible solutions of its defense acquisition and procurement represented as KFP.     

The relationship between cultural values and learning preference: the impact of acculturation experiences upon East Asians

Globalization and technology advancement are creating more biculturalism at workplaces and learning settings. However, little is known about acculturation experience and its influence on a person's cultural values and learning preference. The research reported in this study investigates the impact of acculturation experiences upon the relationship between cultural values and learning preference of 292 Far East Asians (from Confucian‐influenced societies) and Asian Americans. Different preferences for learning methods and different levels of traditional cultural values were found between these two groups of adult learners. Acculturation experience was identified as the influential factor for the differences. However, they all still retain their traditional cultural values in various degrees regardless of the length of time the individual had been exposed to the acculturation experience. The impact of cultural values on an adult's learning preference is an area of concern in cross‐cultural training and development.     

Comment on “A new simple square root option pricing model”

Câmara A. and Wang Y.‐H. ( 2010 ) introduce a simple square root option pricing model where the square root of the stock price is governed by a normal distribution. They show that their three‐parameter option pricing model can outperform the Black–Scholes option pricing model. We demonstrate that their assumption possesses an internal inconsistency in that the square root of the stock price can take on negative values. We generalize and revise their assumption so that the internal inconsistency can be avoided, and introduce a new square root option pricing model. The difference in option prices calculated from the two models may not be trivial. © 2011 Wiley Periodicals, Inc. Jrl Fut Mark     

Consumer workers as immaterial labour in the converging media markets: three value‐creation practices

This paper takes a practice‐based approach to consumer studies and focuses on the strategic and productive roles that consumers play as immaterial labour or consumer workers in the converging media markets. Based on a case study of a print media organization and its customers, the aim is to discuss the collaborative practices through which value is created in the market. By means of a textual analysis of online and interview data, three value‐creation practices are abstracted and illustrated: constructing a sense of belonging and collective identity, mutual helping and peer support, and building pride and self‐respect. Overall, the paper suggests that in global media environments, consumer‐customers are playing increasingly significant strategic roles in the practices and processes through which value is co‐created in the market. It is therefore concluded that the idea of consumers, and media audiences in particular, as recipients of communication and targets of marketing activities needs to be problematized and the dynamic strategic roles that consumers currently play in the market need to be acknowledged and actively incorporated into the business praxis of media corporations.     

The effects of acculturation and uncertainty avoidance on foreign resident choice for Korean foods

This study attempts to identify dining-out patterns among foreign residents in South Korea, examining the differences in foreign residents’ attitudes toward Korean foods and behavioral intentions to patronize Korean restaurants based on their acculturation and uncertainty avoidance levels. The results show that foreign residents in South Korea dine out frequently and intend to revisit Korean restaurants. However, the high acculturation group has a more positive attitude toward, better understanding of, and more preference for Korean foods than the low acculturation group. Satisfaction, revisiting, and recommendation intentions for Korean restaurants are higher among the high acculturation group than the low. The low uncertainty avoidance group spends more money for dining out than the high uncertainty avoidance group, who perceive Korean foods as expensive. Attitudes toward, understanding of, and preference for Korean foods, do not differ significantly between the two uncertainty avoidance groups; nor do satisfaction and behavioral intentions to Korean restaurants.
