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

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

In this paper, we examine the determinants of household consumption of newspapers and the amount spent on their purchase by considering several explanatory variables related to household characteristics and the main household wage earner. Results show that the variables have quite similar effects on both the relative probability of buying newspapers and the amount spent. The key variables are the age and occupational status of the main wage earner, the number of household members, income and having to pay for the house, as well as a number of geographical variables. However, certain differences are also observed. The most important is the education of the main wage earner: while its effect on buying newspapers is very small (only those who did not complete primary education are less likely to buy), its effect on the amount spent increases with the level of education. As other studies of cultural goods and services consumption have suggested, education and occupational status are more relevant determinants than income.  相似文献

In view of previous effects of mediated communication on public knowledge, perceptions and concern about sustainability problems, this case study explores a message framing strategy for improving the effectiveness of mediated communication of the somewhat neglected topic of sustainable consumption. It describes how an information campaign on sustainable consumption was strategically framed, employing theories on effective and persuasive communication, and implemented through a community news medium in Christchurch, New Zealand. The resultant impacts of the campaign (significant increases in understanding of sustainable consumption and in the number of parents expressing concern over advertising effects on their children's material desires) were indicative of the potentials of employing strategic message framing for improving mediated communication about sustainability. The study also illustrates the potentials for engaging alternative media in such communication. This paper argues that further steps to develop message framing strategies for mediated communication of sustainable consumption is necessary, as this appears to be a largely neglected area in communication and consumer studies, and concludes with an overview of aspects that may be considered in future communication and other initiatives promoting sustainable consumption as a means for achieving sustainability.  相似文献

This paper reports a qualitative study conducted at four Japanese subsidiaries in China and Vietnam about their process of international knowledge transfer. Building on the literatures concerning the diverse types and characteristics of knowledge in multinational corporations (MNCs), we explore the broad mechanisms adopted and locally generated by the host country subsidiaries for transferring the foreign knowledge and putting the locally embedded knowledge into practical use at the local settings. The findings indicated (1) the limitations of applying a standardized and universal set of knowledge transfer mechanisms without considering local idiosyncrasies and (2) the contributions of local agents and institutions throughout the process of local knowledge adaptation and development.  相似文献

Contemporary management thinking embraces the organizational training theory that sustainable success rests, to a great extent, upon a systematic evaluation of training interventions. However, the evidence indicates that few organizations take adequate steps to assess and analyse the quality and outcomes of their training. The authors seek to develop the existing literature on training evaluation by proposing a new model, specific to management training, which might encourage more and better evaluation by practitioners. Their thesis is that training evaluation is best if it can be based on criteria derived from the objectives of the training and they draw on the management effectiveness literature to inform their proposed model. The study seeks to examine the effect of six evaluation levels – reactions, learning, job behaviour, job performance, organizational team performance and some wider, societal effects – in measuring training interventions with regard to the alterations to learning, transfer and organizational impact. The model was tested with data obtained from 190 middle managers employed by a large banking organization in Greece and the results suggest that there is considerable consistency in the evaluation framework specified. The paper discusses these results and draws conclusions about their practical implications. The study's limitations are considered and some future research needs identified.  相似文献

We use the DATAMATION index of the top 50 domestic IT companies (1975–1995) to track persistence and change at the top of the sector. The trends that we uncover are increasing instability, rejuvenation (declining average age of entrants coupled with increasing average age of quitters), democratization (diminishing revenue inequality at the top) and growing supply‐side intertwining of sub‐sectors and industries within IT due to diversification by long‐term survivors.  相似文献

This paper aims to examine the equivalence of competition mode in a vertically differentiated product market with the relative performance delegation. It demonstrates the equivalence of product quality and social welfare in this delegation game, irrespective of modes of product competition. In addition, in a three‐stage game of quality‐delegation‐quantity (or price), it shows that the delegation coefficient is different between high‐quality and low‐quality firms in an asymmetric vertical differentiated model, and a high‐quality firm makes better use of the delegation than a low‐quality firm.  相似文献

Recent research highlights the role that multinational trading companies may play in impeding price transmission. In markets characterised by imperfect competition, an estimate of the partial elasticity of demand may be of limited practical value if no account is taken of the reaction of competitors. In this paper, we demonstrate the potential for market structure to affect price transmission and trade elasticities, and challenge the presumption that only government intervention can impact upon price transmission, with examples supporting why theory would suggest otherwise.  相似文献
