This paper investigates the role of stochastic volatility and return jumps in reproducing the volatility dynamics and the
shape characteristics of the Korean Composite Stock Price Index (KOSPI) 200 returns distribution. Using efficient method of
moments and reprojection analysis, we find that stochastic volatility models, both with and without return jumps, capture
return dynamics surprisingly well. The stochastic volatility model without return jumps, however, cannot fully reproduce the
conditional kurtosis implied by the data. Return jumps successfully complement this gap. We also find that return jumps are
essential in capturing the volatility smirk effects observed in short-term options.

The optimal asset allocation of the main types of pension funds: a unified framework 总被引:1,自引:0,他引:1
Katarzyna Romaniuk 《The GENEVA Risk and Insurance Review》2007,32(2):113-128
The existing literature deals with the optimal investment strategy of defined benefit (DB) or defined contribution (DC) pension
plans. This article’s objective is to compare the optimal policies of different types of pension plans. This is done by first
defining an original framework, which is based on the distinction between the nature of the guarantee—which can be internal
or external—offered by or to a pension fund. This framework allows to establish links between optimization programs of DC,
DB and targeted money purchase schemes. The case of an internal guarantee appears as a standard portfolio insurer’s problem.
The second kind of guarantee, not analyzed in the literature yet with regard to the resulting optimal policy, is characterized
by the existence of an option in the final wealth definition. Four funds are present in the internal guarantee optimal allocation:
the speculative component, the preference independent guarantee- and contribution-hedge terms and the preference dependent
state variable-hedge fund. The external guarantee program, solved with an original method using the principles of standard
options theory, yields an optimal policy incorporating the delta of the option embodied in the final wealth definition. The
conclusion is that the resulting optimal portfolio policy becomes riskier.

We develop a multiple forest use model to determine the optimal harvest date for a forest stand producing both timber and carbon benefits under a risk of fire. An empirical application is provided for a forest owner producing maritime pine in Southwest of France. Our results indicate that a higher risk of fire will decrease the optimal rotation period. On the contrary, higher carbon prices increase the optimal harvesting age. To investigate the contradictory effects of fire risk and carbon price on forest rotation, we identify the set of carbon prices and fire risks that lead to a given rotation age. We also show that forest owner's willingness to pay for a risk reduction can be substantial (37.33 euros by ha and by year to reduce the annual fire risk from 1.26% to 0.07%). 相似文献

Logistic and power law methodologies for both retrospective and prospective analyses of extended time series describing evolutionary growth processes, in environments with finite resources, are confronted. While power laws may eventually apply only to the early stages of said growth process, the Allee logistic model seems applicable over the entire span of a long range process. On applying the Allee logistic model to both the world population and the world gross domestic product time series, from 1 to 2008 AD, a projection was obtained that along the next few decades the world should experience a new economic boom phase with the world GDP peaking around the year 2020 and proceeding from then on towards a saturation value of about 142 trillion international dollars, while the world population should reach 8.9 billion people by 2050. These results were then used to forecast the behavior of the supply and consumption of energy and food, two of the main commodities that drive the world system. Our findings suggest that unless the currently prevailing focus on economic growth is changed into that of sustainable prosperity, human society may run into a period of serious economical and social struggles with unpredictable political consequences. 相似文献

货币冲击与中国经济波动——基于DSGE模型的数量分析 总被引:1,自引:0,他引:1
基于1993~2008年的季度数据,本文在一个包含Calvo价格粘性的新凯恩斯主义模型中,讨论了中国货币冲击与经济增长的关系。在假定货币政策通过调整货币供给增长实施的前提下,本文根据模型模拟和实际数据的对比以及脉冲响应函数分析得出以下结论:(1)货币并非我国经济波动根源,实际产出对货币供给具有一定反馈作用。(2)通货膨胀的顺周期性和领先增长表明中国经济周期存在总需求拉动的特性。物价波动在中短期主要由货币供应量波动引起。(3)货币政策对实体经济有效但效果有限,货币供给变动对投资的作用效力更大,对消费需求刺激有限。 相似文献

What are the timeless truths of advertising? How can agency leaders manage their teams, their creative talent, and clients? To answer these and other questions, the mythology of the ‘Golden Age of Advertising’ is examined and analyzed herein. Specifically, using ad man Don Draper—protagonist of the fictional, but already culturally iconic, television series Mad Men—as a mythic archetype, lessons are extracted for contemporary advertising practitioners. Ten timeless rules are proposed and explicated in the areas of (1) managing intra-agency leadership processes, (2) managing creative processes, and (3) managing client relationships. 相似文献

This article investigates the differences in yield production, production efficiency, and yield risk for farmers both with and without off‐farm work. Using a nationwide survey of rice farmers in Taiwan, we estimate two stochastic production frontier models that accommodate technical inefficiency and production risk simultaneously for farmers both with and without off‐farm work. The stochastic dominance criterion is then applied to compare the differences in the distributions of the estimated technical efficiency and yield risk between groups. The empirical results indicate that these two groups of farmers use resources in different ways, and off‐farm work is not necessarily associated with lower technical efficiency. For farmers in the lower percentiles of the efficiency distribution, those with off‐farm work are more efficient than their counterparts without off‐farm work. In addition, farmers with off‐farm work face higher production risk and this result is robust for the entire distribution. 相似文献

基于随机前沿生产函数的我国烟草企业效率分析 总被引:1,自引:0,他引:1
本文选取12家烟草企业作为研究对象,利用随机前沿生产函数考察了从2001年到2005年5年期间的烟草企业生产效率.研究结果表明:中国烟草企业之间的生产效率差异并不大;企业规模与企业的生产效率呈正比例关系.本文研究结果的重要政策含义是,如果继续提高烟草企业的生产效率,就必须打破企业间的市场分割,深化企业间的联合重组,保持企业的适度规模. 相似文献
