We examine the impact of the introduction of VIX exchange‐traded products (ETPs) on the information content and pricing efficiency of VIX futures. We document that trades in VIX futures have become less informative and that pricing errors exhibit more persistence after the introduction of VIX ETPs. In addition, we observe that the price process of the VIX futures has become noisier over time. These findings suggest that the introduction of the VIX ETPs had a prominent effect on the properties and dynamics of the VIX futures. 相似文献

This study uses an endogenous Markov-switching framework to examine the interrelatedness of the volatility dynamics of the US and Korean markets. Previous literature assumes that the US market implied volatility index is exogenous to the Korean implied volatility index. Here, we allow for correlations between the US and Korean variables and suggest two types of endogeneity, namely endogeneity in the regressors and in the regime-switching probabilities. The estimation results show that both types of endogeneity are present in the US variables and that the parameter estimates are quite different when endogeneity is considered, indicating a serious endogeneity bias in the parameter estimates. The results of the endogeneity test for the regressors show that the effects of global shocks are often persistent and may last for as long as six periods. Sub-period analyses indicate that the degrees of endogeneity were especially strong during the global financial crisis. 相似文献

The growing community concern for the environment, and rising energy costs to consumers, has led many power utility companies to adopt strategies aimed at reducing energy consumption in the home and workplace. These strategies have typically been based on extrinsically regulated pricing mechanisms. Although more intrinsically driven interventions have been examined, they are often complex and expensive to implement due in part to the high level of human interaction involved. This two‐part study suggests simpler more cost‐efficient alternatives to enhancing energy saving. It does this via two separate but related studies that examined the application of self‐determination theory (SDT) and word of mouth (WOM) within online communities. The findings suggest a significant increase in reported energy‐saving behaviors over time supporting the role of SDT. There was also evidence that positive WOM increases satisfaction of the three psychological needs of autonomy, competence, and relatedness, further enhancing energy‐saving behavior. These findings have important implications for marketers in terms of behavior change. 相似文献

Individuals can claim Social Security at any age from 62 to 70, although most claim at 62. We show that expected present value calculations substantially understate both the optimal claim age and the losses resulting from early claiming because they ignore the value of the additional longevity insurance acquired because of delay. Using numerical optimization techniques, we illustrate that the optimal claim age is between 67 and 70. We calculate that the amount by which benefits payable at suboptimal ages must be increased so that a household is indifferent between claiming at those ages and the optimal combination of ages can be as high as 19.0 percent. 相似文献

Relatively little is understood about factors triggering entrepreneurial behaviour within organizations not driven by profit motives. Governance plays an important role in non‐profits, particularly boards of directors. Integrating resource‐based theory and entrepreneurial orientation research, we examine the influence of non‐profit boards as strategic resources shaping the organization's entrepreneurial orientation and performance. In particular, we focus on the non‐profit board's underlying behavioural orientations, or the extent to which the board is strategic, activist, conservative, and cohesive. Findings from a cross‐sectional survey on arts and culture organizations demonstrate that three of these behavioural orientations impact levels of entrepreneurship occurring within non‐profits. Higher levels of entrepreneurship affect social performance, but not financial performance. 相似文献

Marketing and entrepreneurship have long been recognized as two key responsibilities of the firm. Despite their tight integration in practice, marketing and entrepreneurship as domains of scholarly inquiry have largely progressed within their respective disciplinary boundaries with minimal cross-disciplinary fertilization. Furthermore, although firms increasingly undertake their marketing and entrepreneurial activities across diverse settings, academe has provided little insight into how changes in the institutional environment may substantially alter the processes and outcomes of these undertakings. Herein, we integrate research on marketing activities, the entrepreneurship process, and institutional theory in an effort to address this gap. We first discuss market orientation as enhancing a firm??s opportunity recognition and innovation, whereas marketing mix decisions enhance opportunity exploitation. We then examine how entrepreneurship leads to innovation directed toward market orientation and marketing mix activities. Based on this foundation, we examine differences in marketing and entrepreneurship activities across institutional contexts. 相似文献

This experiment examined the influence of corporate social responsibility and price on consumer responses. Scenarios were created to manipulate corporate social responsibility and price across two domains (environment and philanthropy). Results from a national sample of adults indicate that corporate social responsibility in both domains had a positive impact on evaluation of the company and purchase intent. Furthermore, in the environmental domain corporate social responsibility affected purchase intent more strongly than price did. 相似文献

For three years in Bolivia (2002–2005) the INNOVA Project finished researching several technologies for sustainable agriculture, started by earlier DFID-funded projects. Before INNOVA started critics suggested that these technologies should be discarded in favour of a demand survey. Instead, INNOVA kept the existing technologies, but judged the demand for them with several methods (CIAL, sondeo technology fair, and others). INNOVA found that there was demand for some of the technologies, but that a survey would have missed much of the demand, which is implicit. That is, people are not initially aware of all their problems or of all the possible solutions. Over the years, farmers made more specific, sophisticated demands on the technologies, which evolved as a result. Demand and supply of farm technology are like two sides of an unfolding conversation. 相似文献
