We provide a new framework for estimating the systematic and idiosyncratic jump tail risks in financial asset prices. Our estimates are based on in-fill asymptotics for directly identifying the jumps, together with Extreme Value Theory (EVT) approximations and methods-of-moments for assessing the tail decay parameters and tail dependencies. On implementing the procedures with a panel of intraday prices for a large cross-section of individual stocks and the S&P 500 market portfolio, we find that the distributions of the systematic and idiosyncratic jumps are both generally heavy-tailed and close to symmetric, and show how the jump tail dependencies deduced from the high-frequency data together with the day-to-day variation in the diffusive volatility account for the “extreme” joint dependencies observed at the daily level. 相似文献

Since the seminal contribution of Jackson and Wolinsky (J Econ Theory 71(1):44–74, 1996) it has been widely acknowledged that the formation of social networks exhibits a general conflict between individual strategic
behavior and collective outcome. What has not been studied systematically are the sources of inefficiency. We approach this
omission by analyzing the role of positive and negative externalities of link formation. This yields general results that
relate situations of positive externalities with stable networks that cannot be “too dense” in a well-defined sense, while
situations with negative externalities tend to induce “too dense” networks. Those results are neither restricted to specific
assumptions on the agents’ preferences (e.g. homogeneity), nor to a specific notion of stability or efficiency. 相似文献

Sweeney (2003) has stated that Anselm of Canterbury produced a paradoxical understanding: God is both inaccessible and obvious (p. 17). The current article proceeds analogically from Anselm's works to a consideration of whether Leadership Studies and the Social Sciences in general can access the obvious omnipresence of History. Finding that neither Leadership Studies nor the other Social Sciences can access that which is obvious, it then extends, in an Anselmian paradox, to discuss the inevitable use of History in Leadership Studies. 相似文献

Disclosure and the cost of equity in international cross-listing 总被引:1,自引:1,他引:0

In this paper, we examine the relationship between disclosure level and the cost of equity capital for a sample of international
firms cross-listing on the New York Stock Exchange. Increased disclosure has the potential to reduce information asymmetry,
reduce the cost of financing and increase analyst following. Using an international asset pricing model, we find that listing
firms experience a decrease in both disclosure risk and systematic risk while matching firms do not. Further, we find that
the magnitude of the decrease is related to three types of disclosure: accounting standards; analyst following; and exchange/regulatory
investor protection. Our results suggest that increased disclosure through accounting standards is beneficial to investors
and that disclosure can be accomplished through information intermediaries, e.g., analyst following. For firms with the lowest
levels of disclosure prior to cross-listing, all three types of disclosure appear to be valuable.

A truism in the marketing literature, and among many marketing practitioners, is that requiring consumers to wait negatively
impacts quality evaluations, purchase intentions and a range of other important outcomes. However, it is also true that consumer
waiting or queuing has historically been considered from an operations perspective. The present research takes a different
approach and examines waits in the context of their ability to function as a signal of quality. Four experiments demonstrate
a required wait can indeed signal quality to consumers and increase, rather than decrease, both purchase intentions and actual
experienced satisfaction. Three moderators of this effect are examined: preexisting knowledge, consumption motivations, and
the extent to which quality is difficult to objectively determine. The results suggest in situations where quality is important,
unknown or ambiguous, managers may increase consumer satisfaction by making consumers wait. 相似文献

Previous studies have indicated that travel satisfaction - the experienced emotions during, and cognitive evaluation of, a trip - can be affected by travel mode choice and other trip characteristics. However, as satisfactory trips might improve a person's attitude towards the used mode, persons may be more likely to use that same mode for future trips of the same kind. Hence, a cyclical process between travel mode choice and travel satisfaction might occur. In this paper we begin to analyse this process—using a structural equation modelling approach on cross-sectional data—for people who engage in walking and cycling for leisure trips in the Belgian city of Ghent. The focus on walking and cycling reflects recent studies indicating that active travel is often associated with the highest levels of travel satisfaction. Results of this exploratory analysis offer tentative support for the idea of a cyclical process: the evaluation of walking and cycling trips positively affects the respondents' attitude towards the respective mode, which in turn has a positive effect on choosing that mode. 相似文献
