We study the skewness premium (SK) introduced by Bates [J. Finance, 1991, 46(3), 1009–1044] in a general context using Lévy processes. Under a symmetry condition, Fajardo and Mordecki [Quant. Finance, 2006, 6(3), 219–227] obtained that SK is given by Bates' x% rule. In this paper, we study SK in the absence of that symmetry condition. More exactly, we derive sufficient conditions for the excess of SK to be positive or negative, in terms of the characteristic triplet of the Lévy process under a risk-neutral measure. 相似文献

Micro-multinational enterprises (mMNEs) represent a new breed of smaller firms in the field of international entrepreneurship. This study investigates the effects of the three sets of variables, namely international entrepreneurship (which encompasses innovativeness, proactiveness and risk-taking propensity), networking and learning on the probability that a firm will become a MNE. Drawing upon a survey of the activities of 116 Chilean internationalized small- and medium-sized firms and utilizing a logistic regression analysis, this study suggests that risk-taking propensity and networking with domestic and international partners increase the likelihood that the firm will become a mMNE. Our findings confirm the predictive validity of the international entrepreneurship and networking perspectives. Because of the positive association between mMNEs and international performance, the suggestions for management of internationalized firms are to nurture a risk-taking propensity and cultivate a networking orientation. 相似文献

This paper investigates the direct and combined impacts of trade facilitation and information and communication technology (ICT) on bilateral flows of 25 sub-Saharan countries. For that purpose, we select time to export and import as specific trade facilitation indicators and broadband use to study ICT impacts. Our sample covers a total of 93 countries over the period 2004–2018. By preprocessing data analysis, we impute time costs missing values, an essential shortcoming of the available databases, to study trade facilitation over time. Lastly, we employ a gravity model and implement a Bonus Vetus Estimation. Our results show that broadband use exerts a positive and significant effect on trade, especially relevant for intra-African trade flows. Furthermore, the combined effects indicate that broadband also modulates the negative impacts of time to export and time to import in the case of intra-SSA countries' trade. The more significant result is found for time to export. Our results also confirm that time costs are not only particularly harmful to intra-African trade but also negatively impact trade flows from SSA countries to the rest of the world. These outcomes show the importance of coordinating trade facilitation and digital transformation policies, particularly those devoted to digitally transforming African customs. 相似文献
