This study derives approximate valuation formulas for basket options and Asian options under the jump‐diffusion process. To obtain an approximation for options prices under the jump‐diffusion process, we extend the Taylor expansion method developed by Ju N. ( 2002 ) under the diffusion process. We show that the Taylor expansion method, suggested in this study, provides better pricing performance as compared to log‐normal or four‐moment methods. The performance improvement using the Taylor expansion method increases as the time to maturity increases. In addition, our numerical analysis shows that jump effects become significant when the expected jump sizes take large negative values. © 2011 Wiley Periodicals, Inc.

While commitment is among the key constructs of consumer–brand relationships, past research has regarded the impact of predictors of brand commitment as being linear and has ignored potential interactive effects among the different antecedents. Applying the investment model of interpersonal relationship, the present research examines the dynamic interplay among the key determinants of consumers' commitment to their relationship with brands (satisfaction, alternatives, and investment) and substantiates the roles of the antecedents in consumer–brand relationship contexts. Results of two studies demonstrate that greater consumer satisfaction and investment and less attractive alternatives lead to a higher level of consumers' commitment to their relationship with a brand. Most important, the results suggest that the perceived size of investment exerts a stronger impact on brand relationship commitment when satisfaction is low while making no significant difference in the commitment level when satisfaction is high. Conversely, the influence of alternative attractiveness on brand relationship commitment appeared to be largely monotonic. © 2010 Wiley Periodicals, Inc.  相似文献

High accessibility to Internet technology and popularization of focus media has given rise to various emerging subcultures among the younger generation who constantly seek novelty. The otaku is such an adolescent subculture of avid collectors who have a special lifestyle and who are obsessed with anime products. This study explores this specific adolescent segment's traits and purchasing behavior patterns. A focus‐group interview was conducted with some adolescent otaku to allow them to express their opinions and purchasing behaviors. Then, a questionnaire was developed based on the interview's findings, and data from a survey of 105 respondents were collected. Exploratory factor analysis was applied to extract the otaku's trait factors, while confirmatory factor analysis and structural equation modeling were used for the verification of the scale and structural model, respectively. The results show that the adolescent otaku present an obsessive preference for visual perception. The main factor influencing the otaku's purchasing intentions in terms of animation, comics, and games (ACG) is their strong interest in and participation willingness toward ACG. Strategic marketing directions applied to this adolescent group should emphasize information visualization to entice their buying behavior.  相似文献

This study examines the effect of advertising expenditure on strengthening a firm’s intangible capital and firm value by attracting the public on the firm’s visibility and then investigates the role of advertising expenditures on a banking firm’s market value, liquidity, and breadth of ownership. The empirical results find that the advertising has a significantly positive effect on banking firm’s share value, liquidity, and institutional holdings. Consequently, this study concludes that advertising benefits banking firms through increased investor perceptions of such firms. In particular, the findings provide additional support for the home bias phenomena, in which investors prefer to invest in familiar stocks.  相似文献

We examine the impact of corporate social responsibility (CSR) activities on loan spreads of syndicated bank loans, with a particular interest in how CSR and credit ratings are interrelated as a joint determinant of loan spreads. Focusing on private debt contracts, we show that both CSR strengths and concerns are related to their loan spreads. CSR strengths work to lower firm risk, hence reducing the loan spread, whereas CSR concerns increase firm risk, thus increasing the loan spread. Once we include detailed credit rating information in the models, however, CSR concerns lose significance, but CSR strengths remain significantly related to the loan spread. We also find that both CSR strengths and CSR concerns are related to loan spread for non-rated firms, but the CSR concern effect is stronger than the CSR strength effect for these firms. A further test shows that firm risk measured by stock return volatility plays as a direct channel through which a firm’s CSR activities affect loan spreads, whose result lends further support to our main results. Overall, our results provide strong evidence that CSR matters to the pricing of loan contracts beyond credit rating information and the results remain robust to the possible firm size effect and the endogeneity issues.  相似文献

Focusing on a product, this paper reconstructs the concept of technological systems first introduced by Carlsson and Stankiewicz (1991) in this Journal. Based on the model, we analyze the evolution process and performance of Korea's technological system for computer numerically controlled (CNC) machine tools as a catching-up case. The study shows that the length of 'learning period' for the system was substantial, even in a catching-up case. Especially, in the Korean case, the government played a 'macro-entrepreneurial' role in the molding of the technological system by giving legitimacy to the system, by mobilizing a nation-specific industrial organization of Chaebol system, and by enhancing the academia-industry-research institution links.JEL Classification: L52, L61, O30We thank two anonymous referees for very helpful comments and suggestions.Correspondence to: B.

Consumer-generated product reviews are a driving force behind online purchases; at the same time, unfavorable reviews can discourage interested online shoppers and eventually hurt the brand. The objective of this exploratory study was to analyze a diverse range of characteristics and the valence of online product reviews that would aid in responding to customer dissatisfaction. Product reviews (N = 1982) from Amazon.com were collected and content analyzed. Some of the key findings include the following: (a) price was the most commonly discussed product feature; (b) online shoppers found two-sided reviews to be most informative, contradicting the commonly held assumption that negative reviews were more informative and diagnostic in nature; and (c) ‘no action’ was the most common end action across two-sided and negative reviews, indicating that varying levels of dissatisfaction might not always lead to a negative end action. Implications for marketers are discussed.  相似文献

We present a complete profile of firms’ foreign currency borrowing surrounding the 2007 global financial crisis. Employing extensive data from Korean firms during 2002–2012, we find that foreign currency borrowing is significantly related to firm attributes of export revenues, firm size, tangible assets and asset growth, as well as to macro-level factors. These results offer two important implications. First, macroeconomic factors alone cannot fully explain firms’ foreign currency borrowing. Second and more importantly, these firm attributes are indicative of a lower default probability and larger collateral value, which would not only facilitate borrowers’ access to foreign currency debt markets but also offer lenders a better protective cushion from possible loan defaults in the face of exchange rate changes and information asymmetry on borrowers’ credits. Period wise, asset-related firm attributes have more pronounced effects in the post- than pre-crisis period. We further show that banking regulations following the crisis effectively limit the access to foreign currency borrowing by Korean firms, most significantly by those belonging to large business groups.  相似文献

We develop an input–output methodology to estimate how Chinese exports affected the country's total domestic value added (DVA) and employment in the years 2002 and 2007. For every US$1000 dollar of Chinese exports in 2007 (2002), DVA and employment are estimated to be US$591 (US$466) and 0.096 (0.242) person-year, respectively. To implement these estimations, we use hitherto unpublished Chinese government data to construct several completely new datasets, including an input–output table with separate input–output and employment-output coefficients for processing exports, non-processing exports, and output for domestic use. We hypothesize that, in comparison with the export sector, China's domestic sector would be relatively autarkic due to China's history of central planning. We expect that exports would generate less DVA and employment than output for domestic use. Processing exports, which are highly dependent on imported inputs, would similarly generate less DVA and employment than non-processing exports. Our findings support these expectations. For both 2002 and 2007, the DVA and employment effects of domestic final demand were higher than those of non-processing exports, which were in turn higher than those of processing exports. However, with the progress of economic reforms, we found that the total DVAs of exports and domestic final demand have converged from 2002 to 2007.  相似文献

Maximum entropy autoregressive conditional heteroskedasticity model   总被引:2,自引:0,他引:2  
In many applications, it has been found that the autoregressive conditional heteroskedasticity (ARCH) model under the conditional normal or Student’s t distributions are not general enough to account for the excess kurtosis in the data. Moreover, asymmetry in the financial data is rarely modeled in a systematic way. In this paper, we suggest a general density function based on the maximum entropy (ME) approach that takes account of asymmetry, excess kurtosis and also of high peakedness. The ME principle is based on the efficient use of available information, and as is well known, many of the standard family of distributions can be derived from the ME approach. We demonstrate how we can extract information functional from the data in the form of moment functions. We also propose a test procedure for selecting appropriate moment functions. Our procedure is illustrated with an application to the NYSE stock returns. The empirical results reveal that the ME approach with a fewer moment functions leads to a model that captures the stylized facts quite effectively.  相似文献
