Valuation of Discrete Dynamic Fund Protection Under Lévy Processes

Abstract

This paper investigates the valuation of discrete dynamic fund protection (DFP) under Levy processes. Specifically, the analytical solution of discrete DFP under Lévy processes is obtained in terms of Fourier transforms. The derivation uses Spitzer’s formula and leads to a recursion on computing the characteristic function of the maximum protection-to-fund ratio using the Fourier inversion. DFP can then be valued efficiently and accurately via the fast Fourier transform. The pricing behavior of the discrete DFP is numerically examined using several Levy processes, such as geometric Brownian motion, jump-diffusion models, and variance gamma process. Numerical experiments confirm that the proposed approach produces highly accurate discrete DFP values within 1 second.     

Gender preference and transfers from parents to children: an inter-regional comparison

This paper examines whether parents exhibit gender preference in the allocation of family resources to their adult children. Gender preference is defined in the context of an altruistic model for inter-vivos transfer from parents to children extended to include educational investment. Data from the Health and Retirement Study (United States) and the Korean Longitudinal Study of Ageing are used to show that the degree of gender preference differs across these culturally distinct regions. Among Korean families, empirical results point to male preference as sons receive larger inter-vivos transfers and attain higher levels of education compared with daughters. In contrast, the evidence pertaining to gender preference among American families points to daughter preference as inter-vivos transfers and educational investment is generally higher among female adult children.     

Is a Picture Always Worth a Thousand Words? The Impact of Presentation Formats in Consumers' Early Evaluations of Really New Products (RNPs)

Really new products (RNPs) enable consumers to do things they have never been able to do before. However, research has shown that consumers have difficulties understanding the benefits of such novel products, and therefore, adoption intentions remain low. Mental simulations and analogies have been identified as effective framing strategies to convey the benefits of RNPs. However, existing research has focused solely on the use of mental simulations and analogies conveyed using words, whereas these can also be conveyed using pictures. Although the general consumer research literature points to a superiority effect of pictures, because the underlying mechanisms that individuals use to understand RNPs differ entirely from those used for traditional products, there is a need to study the impact of pictures for RNPs. Moreover, prior work has not examined differences in RNP type. The present research argues that RNPs can be utilitarian, hedonic, or hybrid and that the optimal presentation format (words versus pictures) is contingent upon the type of RNP considered. Consequently, failure to acknowledge this distinction could lead to negative consequences. The present study aims to identify the impact of alternative presentation formats (i.e., words versus pictures) presented using different framing strategies (i.e., analogies versus mental simulations) on individual responses (i.e., product comprehension and attitude to the product) to three types of RNPs (i.e., utilitarian versus hedonic versus hybrid). Hypotheses are tested by means of an experimental study. The results of the study show that the effectiveness of alternative combinations of framing strategies and presentation formats in enhancing comprehension and attitude for RNPs depends on product type (utilitarian versus hedonic versus hybrid). The empirical findings presented not only extend prior work on consumer responses to mental simulations and analogies for RNPs, but also establish connections between this literature and an underdeveloped stream of research on hybrid products, as well as a broader stream of research on utilitarian versus hedonic product benefits. The findings suggest that practitioners may not have been using optimal marketing communications strategies to convey the benefits of RNPs. Strategies that may help enhance consumer responses to RNPs by taking into consideration product type (utilitarian versus hedonic versus hybrid) are put forward.     

Path‐dependent currency options with mean reversion

This paper develops a path‐dependent currency option pricing framework in which the exchange rate follows a mean‐reverting lognormal process. Analytical solutions are derived for barrier options with a constant barrier, lookback options, and turbo warrants. As the analytical solutions are obtained using a Laplace transform, this study numerically shows that the solution implemented with a numerical Laplace inversion is efficient and accurate. The pricing behavior of path‐dependent options with mean reversion is contrasted with the Black‐Scholes model. © 2008 Wiley Periodicals, Inc. Jrl Fut Mark 28:275–293, 2008

‘Does it Really Affect Me?’ Tourism Destination Narratives,Destination Image,and the Intention to Visit: Examining the Moderating Effect of Narrative Transportation

The extent to which tourism destination marketing narratives with different themes influence readers by imaginatively ‘transporting’ them is quite varied. This study investigates the different degrees of influence such narratives have on destination image and the intention to visit, exploring how the intensity of readers' experiences of being transported by narratives with different themes can influence their intention to visit the places described. Our results reveal the extent to which different narrative themes affect destination image and significantly influence readers' intention to visit. The extent to which narratives with different themes make readers feel transported also has a significant moderating effect on their intention to visit. Copyright © 2015 John Wiley & Sons, Ltd.     

Inventories and optimal monetary policy in a small open economy

We study how inventory investment affects the design of optimal monetary policy in a New Keynesian small open economy model. We find that under producer currency pricing, when the intratemporal elasticity of substitution is smaller than 1, optimal monetary policy in our model with inventories is similar to a standard model without inventories. However, when the intratemporal elasticity of substitution is larger than 1, inventory investment increases the importance of nominal exchange rate stabilization relative to a standard model without inventories. The importance of nominal exchange rate stabilization increases with the intratemporal elasticity of substitution.

Relationship between leader�Cmember exchange and organizational citizenship behaviors: Examining the moderating role of empowerment

This study addresses the moderating role of empowerment on the relationship between leader?Cmember exchange (LMX) quality and subordinates?? organizational citizenship behavior (OCB). Using hierarchical multilevel analyses, we found that LMX is positively related to OCB. Likewise, we found that team-level empowerment climate is positively related to individual-level feelings of empowerment, which, in turn, positively moderate the positive effect of LMX on OCB.
