In this paper, we propose a general technique to develop first- and second-order closed-form approximation formulas for short-maturity options with random strikes. Our method is based on a change of numeraire and on Malliavin calculus techniques, which allow us to study the corresponding short-maturity implied volatility skew and to obtain simple closed-form approximation formulas depending on the derivative operator. The numerical analysis shows that these formulas are extremely accurate and improve some previous approaches for two-asset and three-asset spread options such as Kirk’s formula or the decomposition method presented in Alòs et al. [Energy Risk, 2011, 9, 52–57]. This methodology is not model-dependent, and it can be applied to the case of random interest rates and volatilities. 相似文献

The present study examines whether women involved with career work have shopping attitudes and purchase participation preferences different from those of women involved in non-career work. It finds that career women do differ from their non-career counterparts with regard to several attitudes that have been related to shopping. The attitudinal changes associated with careers and the socioeconomic resources that accompany such work, however, appear to have only an indirect relationship to preference for mail/phone order buying methods. In addition, career status could not be linked to willingness to expand or contract the traditional areas of female purchase jurisdiction. 相似文献

In this paper we apply a model of early industrialization to the case of New Zealand and Uruguay in 1870–1940. We show how differences in agricultural institutions may have produced different development paths in two countries which were similar under many respects. While in New Zealand the active role of the Crown in regulating the land market facilitated access to land, in Uruguay land was seized by a small group of large landowners. Our model shows that land concentration may have negatively influenced industrialization and growth by impeding the formation of a large group of middle-income landowners and, as a consequence, the development of a domestic demand for basic manufactures. We support this view with a comparative analysis of agricultural institutions and industrial development in New Zealand and Uruguay. 相似文献

In this article, we date the ‘recession’ and ‘expansion’ phases of 46 stock markets around the world from December 1994 to September 2013. We use the Harding and Pagan methodology to identify peaks and troughs in these stock market indices. This approach enables us to establish periods of synchronization between the markets based on the timing of peaks and troughs and to measure this synchronization by means of the Harding and Pagan statistic. We find that several recent world crisis episodes and simultaneous recoveries can be identified with this method. We also present evidence demonstrating an increase in the pro-cyclicality of stock markets around the world. 相似文献

This paper describes a dynamic, multisectoral model of a less developed economy in which investment and income distribution policies influence structural change and the pattern of trade. That is, the model considers a Keynesian 'socialised investment' function and distributional policies that, by their effect on demand, could be also described as Keynesian. The model is used to analyse the effects of different policy regimes in the Argentine economy. In an environment characterised by enduring stagnation, investment policies aimed at increasing the degree of economic autonomy and self-sufficiency do not succeed in significantly changing output and trade patterns, and in reducing the degree of openness of the economy. From a long term perspective, however, stagnation is not necessarily a permanent condition. A new environment of higher growth could evolve from the consolidation of a new technological paradigm and the emergence of new socioeconomic norms and mechanisms. In an environment of lower uncertainty and higher efficacy of the investment, model simulation shows that investment policy is quite successful in augmenting the degree of autonomy and self-sufficiency of the economy. Also, income redistribution has a positive impact on income and welfare growth. 相似文献

We investigate the relationship between entrepreneurial capacities and firm performance. More specifically, we investigate the effects of radical innovation and learning orientation on business performance. We test the effects of entrepreneurial orientation on learning orientation and radical innovation. The results suggest that radical product innovation and companies' orientation to learn have a positive effect on organizational performance. Additionally, we find that entrepreneurial orientation positively influences a firm's capability to learn and innovate. Our findings also show a direct effect of learning orientation on radical innovation, which means that companies with a higher proclivity to learn are more likely to create products and processes, representing a major departure from the state of current knowledge.

We explore whether the expectation of debt forgiveness discourages developing countries from attaining sustainable fiscal independence through improving their tax effort. While the international financial community advises poor countries to improve revenue mobilization, the same international community routinely bails out poor countries that fail to meet their loan repayment obligations, among other reasons as a result of the low tax effort they exercise. The act of bailing out creates an expectation about receiving debt forgiveness time and again in the future. The key prediction of our theoretical framework is that in the presence of debt forgiveness, countries’ tax efforts will decline and more so the higher the intensity of the bailouts. We test this proposition using data for 55 countries from 1995 to 2015. We find that debt forgiveness is significant in lowering tax effort. In addressing the potential of reverse causality, we also find that the international financial community has been more forgiving to countries that exert lower tax effort. These results, which are robust to various specifications, have significant policy implications for donor and recipient countries. 相似文献
